    The Bureau of Reclamation is largest wholesaler of water in the United States. Located in the 17 western states, Reclamation serves water to 31 million people, provides irrigated water to 20 percent of Western farmers, and is the second largest producer of hydroelectric power in the United States. Through these activities, Reclamation generates large amounts of water and water-related data, describing reservoirs and river system conditions, hydropower, environmental compliance activities, infrastructure assets, and other aspects of Reclamation's mission activities. Reclamation aims to make water and water-related data sets more easily found, accessed, and used in decision-making activities in order to benefit the public, private sector, and research communities. Historically, there has not been an integrated, bureau-wide system to store data in machine-readable formats; nor a system to permit centralized browsing, open access, and web-services. Reclamation began addressing these limitations by developing the Reclamation Water Information System (RWIS), released in Spring 2017 (https://water.usbr.gov/). A bureau-wide team contributed to RWIS development, including water data stewards, database administrators, and information technology (IT) specialists. The first RWIS release publishes reservoir time series data from Reclamation's five regions and includes a map interface for sites identification, a query interface for data discovery and access, and web-services for automated retrieval. As RWIS enhancement continues, the development team is developing a companion system - the Reclamation Information Sharing Environment (RISE) - to provide access to the other data subjects and types (geospatial, documents). While RWIS and RISE are promising starts, Reclamation continues to face challenges in addressing open water data goals: making data consolidation and open publishing a value-added activity for programs that publish data locally, going beyond providing open access

    Burkardt, Nina; Ruell, Emily W.

    2012-01-01

    Water resources in parts of the Western United States are over-allocated, which intensifies the pressure to support water management decisions with strong scientific evidence. Because scientific studies sometimes provide uncertain or competing results or recommendations, science can become a source of disputes during decision-making processes. The Bureau of Reclamation (Reclamation) is an important water manager in the Western United States, and Reclamation decision processes are often contested by a variety of affected constituencies. We conducted a Web-based survey of Reclamation employees to determine (1) which types of disputes over science are occurring and how common they are, (2) which approaches have been used by Reclamation to try to resolve these different types of disputes, (3) how useful Reclamation employees find these approaches at resolving these types of disputes, (4) the final outcomes of these disputes and the decision-making processes that were hindered by the disputes over science, and (5) the potential usefulness of several different types of dispute resolution resources that Reclamation could provide for employees that become involved in disputes over science. The calculated minimum response rate for the survey was 59 percent. Twenty-five percent of respondents indicated that they had been involved in a dispute over science while working at Reclamation. Native species and species listed under the Endangered Species Act of 1973 were the most common issue types reported in these disputes over science. Survey respondents indicated that they used a variety of approaches to resolve disputes over science and rated most approaches as either neutral or somewhat helpful in these endeavors. Future research is needed to determine whether there are additional variables underlying these disputes that were not measured in this survey that may identify when dispute resolution methods are most effective, or whether resolving aspects of these disputes, such as

    The purpose of this study was to characterize the cyanophyte Aphanizomenon flos-aquae (AFA) from Upper Klamath Lake, Oregon, (UKL) and, based on this description, explore uses for AFA, which would have commercial value. AFA collected from UKL in 2010 from eight sites during a period of approximately 2 weeks were similar in composition spatially and temporally. 31P nuclear magnetic resonance analysis of the samples indicated that the AFA samples contained a broad range of phosphorus-containing compounds. The largest variation in organic phosphorus compounds was found in a sample collected from Howard Bay compared with samples collected the sites at Pelican Marina, North Buck Island, Eagle Ridge, Eagle Ridge South, Shoalwater Bay, and Agency Lake South. 31P Nuclear Magnetic Resonance data indicated that the average ratio of inorganic phosphorus (orthophosphate) to organic phosphorus in the AFA samples was approximately 60:40 in extraction solutions of either water or a more rigorous solution of sodium hydroxide plus ethylenediaminetetraacetic acid. This indicates that when AFA cells senesce, die and lyse, cell contents added to the water column contain a broad spectrum of phosphorus-containing compounds approximately 50 percent of which are organic phosphorus compounds. The organic phosphorus content of AFA is directly and significantly related to the total carbon content of AFA. Total concentrations of the elements Al, Ca, Fe, Mg, Ti and Zn were similar in all samples with the exception of elevated iron in the July 27, 2010, sample from Pelican Marina. Iron concentration in the July 27, 2010, Pelican Marina sample was elevated; the concentration of iron in the August 9, 2010, sample from Pelican Marina was indistinguishable from iron in the other AFA samples that were collected. The carbon to nitrogen ratio in all AFA samples that were analyzed was 5.4 plus or minus 0.04 as compared with the Redfield ratio of carbon to nitrogen ratio of 6.6, which could be

  10. Evaluation of alternative groundwater-management strategies for the Bureau of Reclamation Klamath Project, Oregon and California

    Science.gov (United States)

    Wagner, Brian J.; Gannett, Marshall W.

    2014-01-01

    The water resources of the upper Klamath Basin, in southern Oregon and northern California, are managed to achieve various complex and interconnected purposes. Since 2001, irrigators in the Bureau of Reclamation Klamath Irrigation Project (Project) have been required to limit surface-water diversions to protect habitat for endangered freshwater and anadromous fishes. The reductions in irrigation diversions have led to an increased demand for groundwater by Project irrigators, particularly in drought years. The potential effects of sustained pumping on groundwater and surface-water resources have caused concern among Federal and state agencies, Indian tribes, wildlife groups, and groundwater users. To aid in the development of a viable groundwater-management strategy for the Project, the U.S. Geological Survey, in collaboration with the Klamath Water and Power Agency and the Oregon Water Resources Department, developed a groundwater-management model that links groundwater simulation with techniques of constrained optimization. The overall goal of the groundwater-management model is to determine the patterns of groundwater pumping that, to the extent possible, meet the supplemental groundwater demands of the Project. To ensure that groundwater development does not adversely affect groundwater and surface-water resources, the groundwater-management model includes constraints to (1) limit the effects of groundwater withdrawal on groundwater discharge to streams and lakes that support critical habitat for fish listed under the Endangered Species Act, (2) ensure that drawdowns do not exceed limits allowed by Oregon water law, and (3) ensure that groundwater withdrawal does not adversely affect agricultural drain flows that supply a substantial portion of water for irrigators and wildlife refuges in downslope areas of the Project. Groundwater-management alternatives were tested and designed within the framework of the Klamath Basin Restoration Agreement (currently [2013

  13. Reclamation of urban areas

    International Nuclear Information System (INIS)

    Roed, J.

    1986-02-01

    A literature study was conducted in order to compare the effectiveness and cost of different reclamation procedures that may be employed after an accident on a nuclear facility takes place in which radioactive material is released to the atmosphere. A substantial amount of work has been done on reclaming soil and snow-covered surfaces. Using scrapers or other soil-moving equipment decontamination factors are 10-100. (The decontamination factor is the ratio of the contamination before to that after the decontamination procedure). However, information on decontamination of paved areas by simple methods such as firehosing and vacuum sweeping are poorly documented. Therefore, only a very uncertain figure in the range 2-10 can be given for the decontamination factor here. It is recommended that a major effort be made in the future to investigate the efficiency of these simple methods, because of their relatively low cost. Also, more expensive methods for reducing the dose such as vacuuming, road planing and deep plowing are treated because of their feasibility under certain circumstances. Using these methods dose reduction factors in the 2-100 range can be obtained. Very expensive techniques, such as sandblasting, water cannon, flame spalling, etc. are justifiable usable only in special situations and are therefore considered very briefly here. The methods vary widely in cost. A simple method like vacuum sweeping costs $0.004 per square meter of surface; whereas one like road planing can reach $4 per square meter. A more sophisticated technique like flame spalling costs as much as $100 per square meter. (author)

  17. Value of credit bureau reports

    Directory of Open Access Journals (Sweden)

    Brković Milan

    2017-01-01

    Full Text Available An efficient system of credit information sharing contributes to solving the problem of information asymmetry on the credit and financial markets in general. The consequences of the global economic and financial crisis revealed an increasing demand for reliable information and data which could close the existing gap in their insufficiency, misuse or inadequate analytical value for the economic and financial policy makers. In that sense, more attention is directed to the usefulness of credit information sharing and the practical value of information and data contained in credit bureau reports for the purposes of achieving the overall economic policy goals. The fulfillment of that role depends mostly on the credit information sharing system and its characteristics, participants, and procedures. A credit bureau report in the best possible manner reflects all advantages and disadvantages of the established credit information exchange system in terms of its analytical value for the purposes of efficient macroeconomic and macrofinancial policies.

  18. Greening reclamation of arid region

    Energy Technology Data Exchange (ETDEWEB)

    Kamichika, Makio (Tottori Univ. (Japan))

    1989-01-20

    Arid regions occupy a third of the whole land in the world, and desertification in the rimland makes a problem become more acute. It is also a problem that the large part of such areas is distributed in developing countries. Desertification is defined as a phenomenon, by which the ecological system is degenerated by the change of weather conditions and the pressure of human beings and livestock, and productivity of land is markedly deteriorated. In order to prevent desertification and to promote greening reclamation and agricultural development, it is necessary to analyze desertification mechanism in detail. Artificial factors are overpopulation, too much pasturage, and conversion of grassland into farmland. Natural environmental factors are weather conditions, water resources, soil conditions, etc. It is also important for greening reclamation and development of farm land to evaluate the amount of meteorological resources (such as water resources, energy resources, etc.) and to search for the possibility of their utilization. Because of major condition to grow plants is water environment, investigation and development of water resources are important. If a project ignores the cycle of the ecological system, it might be in danger of retrogradation toward desertification. 8 refs., 10 figs., 4 tabs.

  1. Reconstruction of groundwater circulation after seashore reclamation

    2017-04-01

    In recent years, the effects of land reclamation on the coastal groundwater system have received increasing attention in China as extensive reclamation activities have altered the original groundwater dynamics and salinity distribution in the coastal subsurface. Previous studies focused on either the steady-state groundwater flow or the large scale numerical simulation after land reclamation, however the short-period variation of groundwater flow and its impacts on hydrogeochemical system have not often been considered. Furthermore, a permeable coastal boundary assumed exclusively in previous work is often not the case in contemporary engineering practice, and an impermeable coastal boundary with dikes has been adopted in this study. We investigate the temporal variation of groundwater levels in the un-reclaimed clay layer and reclaimed layer based on the continuous observation of 14 monitoring wells in Zhoushan island, China. We use the morphological wave analysis method to study the effect of nonstationary tidal signals on groundwater level fluctuations. The results indicate that the method of continuous wavelet transform is suitable for analyzing the groundwater flow pattern, where short period groundwater level fluctuations are affected by tidal activities through pipes built in the reclamation dike. In particular, the method of discrete wavelet transform (DWT) is proved effective in extracting tidal signals from groundwater level time series. The approximation term in the multi-resolution analysis is well in agreement with original groundwater level data, demonstrating the advantages of the DWT method in obtaining the change trends of geological, hydrological, and climate variables. Additionally, an examination of groundwater samples indicates that saltwater exists in entire reclamation regions. Our study reveals some different groundwater features in reclamation regions where the coastal boundary is impermeable, which could provide significant implications

  2. The state of oil sands wetland reclamation

    Foote, L. [Alberta Univ., Edmonton, AB (Canada)

    2010-07-01

    The state of oil sand and wetlands reclamation was the subject of this presentation. Wildlife habitat and response, plant community and production, and microbial biology were examples of research areas surrounding this body of knowledge. Hydrological research and landscape ecology were discussed along with peatlands and marshes such as the Corvette and the Kia. A few examples of what has been learned in the area of wetlands reclamation was presented. Other topics were also discussed, such as timeframes, pragmatic policy approaches, reclamation costs, research needs and some ideas on maturing the field. It was concluded that environmental conditions change with time and area because of time, chemistry, physics, stoichiometry, as well as biotic mediation and facilitation. figs.

  6. Methods of assessing vegetation reclamation success

    International Nuclear Information System (INIS)

    Walker, D.; Evans, A.N.

    1992-01-01

    Three elements for gauging pipeline right-of-way reclamation success on cultivated land are reviewed. Plant density measurement is a quick and early method of identifying problems. The density criteria is best measured the first season after construction. Crop production, the second element, can be measured in several ways, with weight of crop per unit area being the most definitive. However, reclaimed land may not be fully productive for several years, and control of agricultural production inputs such as fertilizer is needed if comparisons between crop production on disturbed and undisturbed land are to be valid. The third element is vegetation composition, in terms of the presence of weeds and crop sensitivity. For native rangeland, procedures are discussed for assessing reclamation in terms of plant density, vegetative cover and erosion control, weed presence, and range condition. The relationship between density and cover is noted. For forested land, assessment on the basis of density and plant composition is outlined. A sampling procedure is proposed for deciding if a reclamation site meets acceptable reclamation standards. 13 refs., 4 figs., 7 tabs

  8. Risk-based optimization of land reclamation

    Lendering, K.T.; Jonkman, S.N.; Gelder, P.H.A.J.M. van; Peters, D.J.

    2015-01-01

    Large-scale land reclamations are generally constructed by means of a landfill well above mean sea level. This can be costly in areas where good quality fill material is scarce. An alternative to save materials and costs is a ‘polder terminal’. The quay wall acts as a flood defense and the terminal level is well below the level of the quay wall. Compared with a conventional terminal, the costs are lower, but an additional flood risk is introduced. In this paper, a risk-based optimization is developed for a conventional and a polder terminal. It considers the investment and residual flood risk. The method takes into account both the quay wall and terminal level, which determine the probability and damage of flooding. The optimal quay wall level is found by solving a Lambert function numerically. The terminal level is bounded by engineering boundary conditions, i.e. piping and uplift of the cover layer of the terminal yard. It is found that, for a representative case study, the saving of reclamation costs for a polder terminal is larger than the increase of flood risk. The model is applicable to other cases of land reclamation and to similar optimization problems in flood risk management. - Highlights: • A polder terminal can be an attractive alternative for a conventional terminal. • A polder terminal is feasible at locations with high reclamation cost. • A risk-based approach is required to determine the optimal protection levels. • The depth of the polder terminal yard is bounded by uplifting of the cover layer. • This paper can support decisions regarding alternatives for port expansions.

    1981-01-01

    Ninety MGD of municipal secondary effluent is to be reclaimed for use as cooling water in the Palo Verde Nuclear Generating Station in Arizona. The water reclamation plant design criteria are presented for nitrification, lime-soda softening, filtration, and sludge processing. In-pipe storage is used for flow equalization. Forced air down-draft trickling filters with computer-controlled recycle are used for nitrification. Effluent recirculation is used to maintain constant sludge blanket dept in the upflow solids contact clarifier softening units. An influent flow-splitting, gravity-backwash, dual-media filter is used for final suspended solids removal. Rheological data was used in the hydraulic design of sludge piping. Computerized automatic flushing also aids in preventing sludge pumping problems. Reclamation plant design and construction are integrated in one Engineering-Procurement-Construction project conducted by a single company. 5 refs

  10. Comparative study of German and Greek lignite mine reclamation

    International Nuclear Information System (INIS)

    Dietrich, N.L.

    1994-01-01

    The reclamation planning of three European lignite mining districts are compared: amount and extent of planning, integration with mining operations, and results. The districts are: Rheinbraun (Cologne), Leipzig-Borna (''East'' Germany), and Megalopolis (Greece). Lignite mines were visited and mining and reclamation personnel interviewed. The Rheinbraun mines have the most thorough reclamation operations. The integrated mine and reclamation operations are world class in size, scope, and detail of reclamation. A comprehensive landscape and reclamation plan is required in the mine permitting process. The Leipzig-Borna district is the second largest of the districts, studied little pre-mining planning of the post-mining landscape or land uses was evident. Reclamation is not closely integrated with the mining and typically occurs many years after the mining. Reduced lignite production since German reunification has left vast areas of disturbed land with little mining; and no funding for the reclamation of the large areas of mined land reclamation. The Greek Megalopolis mines have mine operations plan, but with no integrated reclamation planning. The initial spoil pile was reclaimed according to the original German mining plan. No pits have been reclaimed, and spoil areas are revegetated sporadically. The Rheinbraun mining operations Cologne which include a post mining landscape/land use plan have integrated and timely reclamation operations. The other two mining operations, which do not have a comprehensive and detailed reclamation and landscape/land use plans, do not integrate reclamation operations with the mining operations. The results are large areas of mined land unreclaimed for many years

    1978-01-01

    Bureau research programs and projects are designed to address many of the State's major concerns in the areas of geologic, energy, mineral, land, and environmental resouces. Research programs incorporate geologic concepts that will build toward an understanding of a specific resource and its impact on human activities. In addition to resource assessments in uranium, lignite, and geopressured geothermal energy, the Bureau continued research into analysis of governmental policy related to energy. Systemic geologic mapping, coastal studies, basin analysis projects, and investigations in other areas of economic geology further indicate the range of research programs carried forward in 1978. Specifically, research on mineral resources and land resources, coastal studies, hydrogeology, basin studies, geologic mapping, and other research (tektites and meteorites, carboniferous of Texas, depositional environments of the Marble Falls Formation, Central Texas) are reported. The establishment of the Mining and Mineral Resources Research Institute is followed. Contracts and grant support and contract reports are listed. The publications eminating from the Bureau are listed. Services rendered by the Bureau and personnel information are included. (MCW)

    Full Text Available Abstract. Disturbed by the mining industry area in Bulgaria is about 24.113 ha of which only 8.253 ha are reclaimed. Reclamation of disturbed areas covers a complex of engineering, technical, ameliorative, agricultural, forestry and other activities, which aim at restoration of the disturbed terrains and their re-entry into economic turnover in accordance with environmental conditions and area landscape. All disturbed lands as well as their adjacent areas that have completely or partially lost productivity as a result of the negative impact of mining activities and land damage are subject to reclamation. Land reclamation is a two-step process which includes: technical reclamation and biological reclamation. Technical reclamation is performed by the land owner and covers cleaning and preparation of the terrain, leveling, final formation and laying a humus soil layer on site by adding appropriate “improvers” (e.g. fertilizers, texture enhancers, etc.. Biological reclamation covers restoration of the productivity of the disturbed areas. Reclamation technologies applied in Bulgaria as a whole have led to a state of these territories that requires both maintenance and search for new ways of integration of the reclaimed landscapes with modern economic activities. The aim of the study is analysis and applying reliable modern practices that ensure good results in visual qualities of landscape and more options for future use of the reclaimed land.

    Teck Coal has undertaken a project to compile data and interpretations from reclamation research conducted at the company's various open-pit metallurgical coal mining operations in British Columbia and Alberta. The reclamation research synthesis project aims to compile into a single document all the reclamation research done on Teck Coal properties, to synthesize the findings of the research in a single reference, to clearly articulate research findings and optimum reclamation practices, and to shape future reclamation and monitoring efforts according to identified challenges or high-priority issues. The implementation involves reproducing all the documents as digital appendices to the synthesis document, creating summaries of every report, and categorizing according to topic area. An in-progress sample of the summary and synthesis completed to date was presented. It focused on the reclamation of ungulate habitat in southeast British Columbia. The sample involved identification of preferred elk browse and forage species, the reclamation of preferred forage species (both grass/forb and tree/shrub), the relative advantages of native and naturalized and introduced grass and forb species, techniques for survival, and nutritional characteristics. The priorities identified were to develop seed mixes to improve performance and meet changing reclamation objectives, to replicate the benefits of individual plant protectors with less cost/effort, and to determine the quantity or proportion of ungulate browse shrub species necessary for high-quality winter-range habitat. The synthesis document is to guide future reclamation work, educate new reclamation practitioners, and contribute more widely to overall reclamation knowledge. 1 ref., 2 tabs., 1 fig.

    Surface mining began in Southwest Virginia in the mid-1940's, however, few or no records were kept before 1950 and it was not until 1966 that the first Virginia reclamation law was passed. Two years later in 1968, the Division of Mined Land Reclamation was created and tree planting began on a uniform basis in Virginia surface mines.

  5. Reclamation of uranium mining and milling disturbances

    Farmer, E.E.; Schuman, G.E.

    1987-01-01

    Since 1945 the history of uranium mining and milling in the US has been a story of wide fluctuations in market prices and in mining and milling capacity. The late 1960's and the 1970's saw a sizeable reduction in the production of yellowcake because of an earlier over-supply, a leveling off of the military demand, and a failure of the nuclear electric power industry to create the anticipated commercial demand. The decline in the domestic production of yellowcake has continued through the early 1980's to the present. Today, there are five operating uranium mills in the US: one in Wyoming, two in Utah, one in New Mexico, and one in Texas. Of these five mills, three are operating on a reduced schedule, as little as three days a month. A significant portion of the current US production of uranium goes overseas to fulfill Japanese, French, and other European contracts. There is still a sizeable reclamation job to be accomplished on old uranium wastes, both tailings impoundments and overburden embankments. Before the Uranium Mill Tailings Control Act of 1978 (PL 95-604), reclamation was frequently omitted altogether, or else done in a haphazard fashion. We do not know the total area of unreclaimed, radioactive, uranium overburden wastes in the western US, but the area is large, probably several thousand hectares. Fortunately, these overburden wastes are almost entirely located in remote areas. Mill tailings are more difficult to reclaim than overburden, and tailings represent a more serious health hazards. There are approximately 25 million metric tons of unreclaimed uranium mill tailings, with variable health hazards, located in the US

  6. The development of a field method for evaluating the success of reclamation efforts on abandoned mine lands

    International Nuclear Information System (INIS)

    Hunsberger, E.L.; Michaud, L.H.

    1994-01-01

    Abandoned Mine Lands (AML) are prevalent throughout Pennsylvania and in other areas of the US. Reclamation of these sites has been an ongoing concern of the Pennsylvania Department of Environmental Resources (PA DER) for over 20 yr. As the state of the technology improves, a variety of techniques have been utilized to rehabilitate AML. These reclamation efforts have resulted in vast improvements in the conditions of the sites, especially in water quality, erosion control, and aesthetic beauty. However, little work has been done to evaluate and document the success of individual reclamation techniques. Working with the Bureau of Abandoned Mine Reclamation, PA DER, a study was conducted at The Pennsylvania State University to address this need. The main goal of the project was to develop an evaluation system that could be easily carried out in the field by one person. The result of this study was the development of the Reclamation Success Evaluation System (RSES). The system utilizes three main parameters to evaluate reclamation success: (1) Surface Water Quality, (2) Extent of Erosion, and (3) Success of the Vegetative Cover. A series of guidelines and recommendations was developed for each of these evaluation parameters. The RSES was tested under field conditions by applying it to a watershed that contains both reclaimed and unreclaimed AML sites. This test proved that the RSES is an easily implemented and effective tool for evaluating the success of AML reclamation efforts. The system facilitates the comparison of reclamation efforts at different sites, it can be conducted by one person, and the results are easily interpreted

    A broad review of mine land reclamation problems and challenges in arid lands is presented with special emphasis on work recently completed in India. The economics of mining in the Indian Desert is second only to agriculture in importance. Lands disturbed by mining, however, have only recently been the focus of reclamation attempts. Studies were made and results compiled of problems associated with germplasm selection, soil, plant and overburden characterization and manipulation, plant establishment methods utilized, soil amendment needs, use and conservation of available water and the evaluation of ecosystem sustainability. Emphasis is made of the need for multi-disciplinary approaches to mine land reclamation research and for the long-term monitoring of reclamation success.

  10. Reclamation of acidified lakes near Sudbury, Ontario

    Energy Technology Data Exchange (ETDEWEB)

    Scheider, W.; Adamski, J.; Paylor, M.

    1975-01-01

    As part of the ministry of the Environment Lake Reclamation Program, Ca(OH)/sub 2/ and CaCO/sub 3/ were used to artificially offset acidic conditions, re-establish buffer systems and reduce heavy metal levels in two low pH lakes near Sudbury, Ontario. Middle and Lohi lakes were treated in the fall of 1973 and monitoring continued into 1975. The lakes upstream of each treated lake, Hannah and Clearwater respectively, were monitored as controls. It was determined that a combination treatment (CaCO/sub 3/ plus Ca(OH)/sub 2/ as opposed to Ca(OH)/sub 2/ only) provided a more stable buffer system and maintained improved water quality for a longer period of time. Microbial and phytoplanktonic populations showed a positive response to treatment, increasing in standing stock. Zooplanktonic and zoobenthic populations decline, probably due to the lethally rapid pH change. Numbers are expected to increase in future in response to the improved water conditions and increased food availability.

    1979-01-01

    The types of solid wastes and effluents produced by the southwestern coal and uranium mining and milling industries are considered, and the current methods for the disposal and reclamation of these materials discussed. The major means of disposing of the solid wastes from both industries is by land fill or in some instances ponding. Sludges or aqueous wastes are normally discharged into settling and evaporative ponds. Basic reclamation measures for nearly all coal and uranium waste disposal sites include solids stabilization, compacting, grading, soil preparation, and revegetation. Impermeable liners and caps are beginning to be applied to disposal sites for some of the more harmful coal and uranium waste materials

    Results of chemical testing are presented of the local reclamants (ashes of various deposits and ferrochromium plant slags) to study the possibilities of their use for chemical soil reclamation. Attention was paid to the investigation of pollutant (strontium) behaviour in the reclamant-acid soil-plant-ground water system. Tracer method was used, 85 Sr was applied as a label. Prospects of zeolite application to control the strontium behaviour following the reclamant introduction into soil were considered. It was shown that zeolite application permitted to regulate strontium behaviour in the reclamant-soil-plant-ground water system. At that the modified zeolites possessing high Sr selectivity are recommended for application

  2. An economic framework for analyzing reclamation after energy extraction in the Powder River Basin of Wyoming

    Science.gov (United States)

    Perry, Abby A.

    Wyoming's economy is highly dependent on natural gas and coal production, but energy extraction degrades rangelands. Federal and state laws and policies govern reclamation of disturbed lands. However, establishing sagebrush plant communities is difficult and defining successful reclamation can be challenging. We analyze reclamation costs in the Powder River Basin of northeastern Wyoming using coal company annual reclamation reports. We also construct a probabilistic mathematical programming model that characterizes a coal company's reclamation decision-,making process and proposes a way to incorporate uncertainty into reclamation modeling. We also use results from a plant sciences field experiment to incorporate costs into optimal seed mix and herbicide choice. This thesis also draws attention to the disconnect between the data biologists collect and the data that economists need to model reclamation decision-making.

  3. Jiangsu coastal highland reclamation and its wetland ecological construction-a case analysis of the Tiaozini reclamation project

    Science.gov (United States)

    Yu, Meixiu; Xu, Xianghong

    2017-04-01

    Reclamation is one potential solution for the increasing demand of new land for living and development. In past centuries, many coastal countries, such as the Netherlands, UK, Japan, South Korea and Singapore, had exploited extensively sea enclosing and reclamation fordefense against storm surges,agricultural and industrial development, as well as for coastal city expansion along the coast. China has continuously reclaimed coastal sea areas from the 1950s. With rapid economic development and increasing population in coastal areas during recent decades, reclamation has been regarded as an effective measure to resolve the land shortage as cities and industries expand, particularly in South-East coastal areas. Jiangsu province, located in East China, has a similar amount of land territory area to the Netherlands, however, its population is almost fivefold instead. Since its coastal area generates large amounts of tidal flat resources due to its unique hydrodynamic and geomorphic conditions, coastal reclamation plays a vital role in guaranteeing the food security for the Jiangsu Province or even the whole nation. The Tiaozini Reclamation Project (TRP), located between N32.720°-32.882°, E120.894°-120.969°, in Jianggang county of Jiangsu coastal region, with an area of 6,746ha, was reclaimed along the prograding muddy silt coast in 2012. It should be noted that the TRP was reclaimed from theoretical bathymetrical datum of about 4.6m. It is estimated that the shoreline moves towards the sea at a rate of 100m/year and the tidal flat raises at a rate of 5 10 cm/year respectively because of the external tidal flat being continually prograding and drying. After finishing reclamation,the TRP develops with nature: for the dried tidal flat high land,developing ecological agriculture after integrated soil improvement with reducing salt and cultivating fertilizer; for the drying tidal flat,developing ecological fishery by inceasing artificial wetland area; for lower tidal flat

    A mass of construction and demolition (C&D) waste are generated in Shanghai every year, and it has become a serious environment problem. Reclaiming the waste concrete to produce recycled aggregate (RA) and recycled aggregate concrete (RAC) is an effective method to reduce the C&D waste. This paper develops a reclamation chain of waste concrete based on the researches and practices in Shanghai. C&D waste management, waste concrete disposition, RA production and RAC preparation are discussed respectively. In addition, technical suggestions are also given according to the findings in practical engineering, which aims to optimize the reclamation chain. The results show that the properties of RA and RAC can well meet the requirement of design and practical application through a series of technical measures. The reclamation chain of waste concrete is necessary and appropriate for Shanghai, which provides more opportunities for the wider application of RA and RAC, and it shows a favorable environmental benefit.

    In several Texas environmental laws, the Bureau of Economic Geology is designated as a planning participant and review agency in the process of fulfilling environmental laws. Two examples are legislation on reclamation of surface mines and regulation of processing low level radioactive wastes. Also, the Bureau is the principal geological reviewer of all Environmental Assessments and Environmental Impact Statements which the Office of the Governor circulates for state review on all major developmental activities in Texas. The BEG continues its strong interest in environmental geology. In February 1988, it recommitted its Land Resources Laboratory, initiated in 1974, toward fulfilling needs of state, county, and city governments for consultation and research on environmental geologic problems. An editorial from another state geological survey would resemble the about description of texas work in environmental geology. State geological surveys have led federal agencies into many developments of environmental geology, complemented federal efforts in their evolution, and continued a strong commitment to the maintenance of a quality environment through innovative geologic studies

  7. Experimental verification of the energetic model of the dry mechanical reclamation process

    Directory of Open Access Journals (Sweden)

    R. Dańko

    2008-04-01

    Full Text Available The experimental results of the dry mechanical reclamation process, which constituted the bases for the verification of the energetic model of this process, developed by the author on the grounds of the Rittinger’s deterministic hypothesis of the crushing process, are presented in the paper. Used foundry sands with bentonite, with water-glass from the floster technology and used sands with furan FL 105 resin were used in the reclamation tests. In the mechanical and mechanical-cryogenic reclamation a wide range of time variations and reclamation conditions influencing intensity of the reclamation process – covering all possible parameters used in industrial devices - were applied. The developed theoretical model constitutes a new tool allowing selecting optimal times for the reclamation treatment of the given spent foundry sand at the assumed process intensity realized in rotor reclaimers - with leaves or rods as grinding elements mounted horizontally on the rotor axis.

    Full Text Available Mining activities will reduce species diversity, whereas forest reclamation would restore the species diversity, which was previously a forested area. This research was conducted in PT Bukit Asam area, in 6 locations, and in natural forest, as a comparison. The objective of this research was identifying biodiversity of plants and birds in a reclamation area which had different planting years through an approach of diversity indices of vegetation and birds (H', index of species similarity of plants and birds, and leaf area index (LAI. Research results showed that secondary succession occurred in the reclamation area. The value of plant diversity index in reclamation area of 1995 planting year exhibited diversity values which approached that of natural forest, except for undergrowth vegetation. Index of plant species similarity between reclamation area and natural forest did not show any presence of similar communities, but the reclamation area of 1995 planting year exhibited values of plant species similarity indices at all strata, ranging from undergrowth vegetation, seedlings, saplings, poles, and trees. Index of bird diversity in reclamation area of planting the year 1998 possessed the highest value and approached that of natural forest, namely 2.43. Reclamation area of 1998 planting year possessed the highest similarity index of bird species, namely 50%. Reclamation area of the planting year 1995 possessed LAI which approached natural forest, namely 1.89. The older the planting year, the larger was the value of LAI, except for the disturbed reclamation area, namely reclamation area of 1996 planting year and reclamation area of 2001 planting year

    OpenAIRE

    Gouin, Clayton David

    2017-01-01

    Alberta’s oil sands are large, naturally occurring deposits of bitumen, a non- renewable, mineral resource. One problem Alberta faces is the scale of ecological disturbance from oil sands mining. Alberta’s current reclamation law for oil sands requires land to be reclaimed to a state of equivalent land capability and reclamation responsibilities are placed on oil companies. Reclamation publications from oil sands mine sites are currently limited. Additionally, less research on stakeholders’ r...

  19. Sea Reclamation Status of Countries around the South China Sea from 1975 to 2010

    Directory of Open Access Journals (Sweden)

    Junjue Zhang

    2017-05-01

    Full Text Available As a way of turning sea into land for living space for humans, the actions of sea reclamation bring about significant benefits. Nevertheless, it is also an under-recognized threat to the environment and the marine ecosystem. Based on images in two periods, sea reclamation information of countries around the South China Sea was extracted from 1975 to 2010. The spatial state and driven forces of sea reclamation are then discussed. Results show that the overall strength of sea reclamation in the South China Sea was great. New reclaimed land added up to 3264 km2. Sea reclamation for fish farming was the main reclamation type and widely distributed in the whole area, especially on the coast from the Pearl River Delta to the Red River Delta, and the coast of Ca Mau Peninsula. Sea reclamation in China and Vietnam was rather significant, which occupies 80.6% of the total reclamation area. Singapore had the highest level of sea reclamation. New reclaimed land for fish farming holds a key role in China, Vietnam, and Indonesia, while new reclaimed land for construction and docks dominated in Malaysia, Singapore, and Brunei. Areas and use-type compositions of new reclaimed land in countries varied greatly due to the differences of economic factors, policy inclination, and landscapes in the respective countries.

  20. Assessment of Reclamation Treatments of Abandoned Farmland in an Arid Region of China

    2016-11-01

    Full Text Available Reclamation of abandoned farmland is crucial to a sustainable agriculture in arid regions. This study aims to evaluate the impact of different reclamation treatments on abandoned salinized farmland. We investigated four artificial reclamation treatments, continuous cotton (CC, continuous alfalfa (CA, tree-wheat intercropping (TW and trees (TS, which were conducted in 2011–2012 in the Manasi River Basin of Xinjiang Province, China. Soil nutrient, microorganism and enzyme activity were examined in comparison with natural succession (CK in an integrated analysis on soil fertility improvement and soil salinization control with these reclamations. Results indicate that the four artificial reclamation treatments are more effective approaches than natural restoration to reclaim abandoned farmland. TW and CA significantly increased soil nutrient content compared to CK. CC reduced soil salinity to the lowest level among all treatments. TW significantly enhanced soil enzyme activity. All four artificial reclamations increased soil microbial populations and soil microbial biomass carbon. TW and CA had the greatest overall optimal effects among the four treatments in terms of the ecological outcomes. If both economic benefits and ecological effects are considered, TW would be the best reclamation mode. The findings from this study will assist in selecting a feasible method for reclamation of abandoned farmland for sustainable agriculture in arid regions.

  1. The influence of reclamation to malaco - assemblages of limestone quarry

    Science.gov (United States)

    Kupka, J.; Svehlakova, H.; Beranek, J.; Lokajickova, B.

    2017-10-01

    Quarries fundamentally change the character of the landscape, both in the mined parts and in its immediate surroundings. Inside the mined areas, there are many different types of microbiotopes, their character is very different from the surrounding ecosystem. Destruction of original biotopes is an opportunity for settlement by new plant and animal communities. To monitor these biodiversity changes in the landscape, appropriate groups of organisms are used. Only a bioindicator that is well processable from a taxonomic point of view and its demands on the environment and its distribution are well-known, gives reliable results. For these reasons, less moving molluscs are used in many works. The territory of the southern part of the Devonian limestone of the Moravian Karst is affected by the industrial mining of limestone. There is forest quarry in Lisen, which was ended in 1997 and a few years later reclamation work was started on parts of the mined area. The study of molluscs in this model territory was used to assess the impact of reclamation methods on the malaco - assemblage’s diversity inside the quarry.

  2. Analysis of effectiveness of used sands reclamation treatment – in various technological devices

    2009-10-01

    Full Text Available The analysis of effectiveness of spent sands reclamation treatment performed in technological devices of various intensity of dry reclamation – during which used binding material is being removed from grain surfaces – is presented in the paper. Variety of reclamation influences was considered via the realization of the so called elementary operations such as: rubbing, grinding and crushing [1-5], which are realised mainly in dry mechanical reclamation devices but also appear in other technological devices for sand preparation.The model rotor reclaimer and two types of mixers used for preparing initial foundry sands with resin U 404 and hardener 100 T3 of the Hüttenes-Albertus Company were applied for tests.The theoretical model for assessing the effectiveness of reclamation treatment developed by the author [3, 4], was experimentally verified [5, 7], with the application of standard testing procedures. The model can be considered a new tool enabling the selection of optimal reclamation times for the given used sand at the assumed intensity of silica sand matrix recovery. Sand mixture of a proper composition fulfilled needed technological properties after total hardening was used as charge material in experiments. The reclamation treatment consisted of mechanical and mechanical-cryogenic reclamation performed within a wide range of times and conditions influencing the treatment intensity.

    Managing and identifying the sources of anthropogenic stress in coastal wetlands requires an in-depth understanding of relationships between species diversity and human activities. Empirical and experimental studies provide clear evidence that coastal reclamation can have profound impacts on marine organisms, but the focus of such studies is generally on comparative or laboratory research. We developed a compound intensity index (reclamation intensity index, RI) on hybrid coastal reclamation, to quantify the impacts of reclamation on coastal ecosystems. We also made use of mean annual absolute changes to a number of biotic variables (biodiversity, species richness, biomass of total macrozoobenthos, and species richness and biomass of Polychaeta, Mollusca, Crustacea, and Echinodermata) to determine Hedges’d index, which is a measure of the potential effects of coastal reclamation. Our results showed that there was significant difference of coastal reclamation intensity between Yellow Sea, East China Sea and South China Sea, the biological changes in effect sizes of the three regions differed greatly over time. Our modelling analyses showed that hybrid coastal reclamation generally had significant negative impacts on species diversity and biomass of macrozoobenthos. These relationships varied among different taxonomic groups and included both linear and nonlinear relationships. The results indicated that a high-intensity of coastal reclamation contributed to a pronounced decline in species diversity and biomass, while lower-intensity reclamation, or reclamation within certain thresholds, resulted in a small increase in species diversity and biomass. These results have important implications for biodiversity conservation and the ecological restoration of coastal wetlands in face of the intensive reclamation activities. (letter)

    The recently reorganized GGOS Bureau of Networks and Observations has many elements that are associated with building and sustaining the infrastructure that supports the Global Geodetic Observing System (GGOS) through the development and maintenance of the International Terrestrial and Celestial Reference Frames, improved gravity field models and their incorporation into the reference frame, the production of precision orbits for missions of interest to GGOS, and many other applications. The affiliated Service Networks (IVS, ILRS, IGS, IDS, and now the IGFS and the PSMSL) continue to grow geographically and to improve core and co-location site performance with newer technologies. Efforts are underway to expand GGOS participation and outreach. Several groups are undertaking initiatives and seeking partnerships to update existing sites and expand the networks in geographic areas void of coverage. New satellites are being launched by the Space Agencies in disciplines relevant to GGOS. Working groups now constitute an integral part of the Bureau, providing key service to GGOS. Their activities include: projecting future network capability and examining trade-off options for station deployment and technology upgrades, developing metadata collection and online availability strategies; improving coordination and information exchange with the missions for better ground-based network response and space-segment adequacy for the realization of GGOS goals; and standardizing site-tie measurement, archiving, and analysis procedures. This talk will present the progress in the Bureau's activities and its efforts to expand the networks and make them more effective in supporting GGOS.

    Honaker, R.Q.; Chugh, Y.P.; Patwardhan, A.

    1998-01-01

    A vast number of coal refuse ponds represent a significant economical resource base that may also be considered to be environmentally harmful. The fine coal fraction in a preparation plant consists of the purest particles in the entire preparation plant and, thus, if recovered, could enhance the quality of the plant product. However, until recently, the ability to effectively recover fine coal has been limited due to the lack of efficient fine particle separation technologies. As a result, a large portion of the fine coal produced in the US during this century has been disposed into refuse pond along with the acid producing components of the associated gangue material. Research conducted by Southern Illinois University scientists has found that advanced fine coal cleaning technologies can be used to recover high quality coal from refuse ponds while also utilizing a novel technique for neutralizing the acid generation potential of the pyrite-rich reject stream. Various circuitry arrangements will be discussed and metallurgical results presented in this publication

  13. Reclamation of plutonium from pyrochemical processing residues

    International Nuclear Information System (INIS)

    Gray, L.W.; Gray, J.H.; Holcomb, H.P.; Chostner, D.F.

    1987-04-01

    Savannah River Laboratory (SRL), Savannah River Plant (SRP), and Rocky Flats Plant (RFP) have jointly developed a process to recover plutonium from molten salt extraction residues. These NaCl, KCL, and MgCl 2 residues, which are generated in the pyrochemical extraction of 241 Am from aged plutonium metal, contain up to 25 wt % dissolved plutonium and up to 2 wt % americium. The overall objective was to develop a process to convert these residues to a pure plutonium metal product and discardable waste. To meet this objective a combination of pyrochemical and aqueous unit operations was used. The first step was to scrub the salt residue with a molten metal (aluminum and magnesium) to form a heterogeneous ''scrub alloy'' containing nominally 25 wt % plutonium. This unit operation, performed at RFP, effectively separated the actinides from the bulk of the chloride salts. After packaging in aluminum cans, the ''scrub alloy'' was then dissolved in a nitric acid - hydrofluoric acid - mercuric nitrate solution at SRP. Residual chloride was separated from the dissolver solution by precipitation with Hg 2 (NO 3 ) 2 followed by centrifuging. Plutonium was then separated from the aluminum, americium and magnesium using the Purex solvent extraction system. The 241 Am was diverted to the waste tank farm, but could be recovered if desired

RSI uses 9 indices from three indicators of environment factor which are coastal resources, building and infrastructure.

  1. Reclamation of abandoned underground mines in the United Kingdom

    International Nuclear Information System (INIS)

    Brook, D.

    1994-01-01

    Since 1980, the Derelict Land Grant program has supported reclamation of abandoned mines in the United Kingdom. The stabilization of large-scale limestone mines in the West Midlands has stimulated the development of new methods of bulk infilling using waste materials as thick pastes. Colliery spoil rock paste develops strengths of 10 to 20 kPa to support roof falls and prevent crown hole collapse. Pulverized fuel ash rock paste develops strengths over 1 MPa where lateral support to pillars is required. Smaller scale mine workings in the West Midlands and elsewhere have been stabilized using conventional grouting techniques, hydraulic and pneumatic stowing, foamed-concrete infill, bulk excavation with controlled backfill, and structural support using bolts, mesh, and shotcrete

    The use of a Geographic Information System (GIS) and related technologies (e.g., Digital cartographic tools, satellite image processing systems) can benefit the planning and monitoring of open-pit mine reclamation activities. PCI Geomatics, in conjunction with Luscar Limited's Line Creek Mine, has developed a GIS-based system designed to store information relevant to planning and assessing reclamation progress. Data that existed in various formats throughout the company, and which had been collected since the mine-planning phase, was integrated into the GIS. The system is used to summarize current reclamation activities and is linked to corporate costing procedures. Monitoring of reclamation activities and quantifying change in the mine area is easily done using the spatial analysis capabilities of the GIS. Assessments of the change in reclamation areas are enhanced by using satellite image data to produce inexpensive and timely information on the land base, and allow the comparison of the health of the vegetation to reclamation areas from year to year. The implemented system substantially reduces the time needed to generate statistics and produce maps for government or internal reports. Also, there are benefits in terms of both cost and effectiveness of reclamation planning

    Coastal reclamation is the gain of land from the sea or coastal wetlands for agricultural purposes, industrial use or port expansions. Large-scale coastal land reclamation can have adverse effects on the coastal environment, including loss of marine habitats and deterioration of coastal water quality. In recent decades, coastal land reclamation has occurred extensively to meet the increasing needs of rapid economic development and urbanization in China. The overall objective of this study is to understand the coastal reclamation status of China from 1979 to 2014 and analyzed its driving factors for mitigating negative ecological effects. The data of coastal reclamation were done with the ERDAS Imagine V9.2 platform and ArcGIS software based on remote images including Landsat, SPOT, ZY-2 and ZY-3. Potential driving factors for sea reclamation were selected based on statistics bulletins and the knowledge of experts in coastal management. In order to understand the relationships among possible impact factors and coastal reclamation, the Partial Least-Squares Regression models was constructed. The analysis results indicated that the total area of reclamation was 11162.89 km2 based on remote sensing images between 1979 and 2014. Shandong Province is the largest reclamation area, reaching 2736.54 km2, and the reclamation is mainly concentrated in Zhejiang, Jiangsu and Liaoning, where the reclamation areas were all more than 1000 km2. According to the remote sensing images, there are three coastal reclamation hotspot regions including Bohai bay (in which is located Liaoning, Tianjin and Hebei), Jiangsu province coastal area and Hangzhou bay (in Zhejiang province). A large scale land reclamation plan of more than 5880 km2 has been made by local government and 2469 km2 has approved by the State Council. From the analyzed results, there is a significant collinearity between these indicators, and no significant correlation between the area of reclamation and selected

    The US Bureau of Mines, in cooperation with the Idaho National Engineering Laboratory (INEL), conducted over 30 hours of melting tests to vitrify simulated low-level radioactive wastes from the INEL. Radioactive Waste Management Complex (RWMC). Five separate waste compositions were investigated, each consisting of noncontaminated soil from the RWMC and surrogate materials used to simulate the actual buried wastes. The RWMC soil and five waste compositions were melted in a 50-lb, single-phase electric arc furnace with a water-cooled shell. These tests were conducted to determine melting parameters in preparation for a large-scale melting campaign to be conducted in the Bureau's 1-metric ton (mt), water-cooled-wall, 3-phase electric arc furnace. Bulk chemical composition was determined for each of the feed materials and for the slag, metal, fume solids, and offgas furnace products, and distributions were calculated for the key elements. The material balance for the furnace operation indicates that from 63 to 84 pct of the feed reported to the slag. Cerium, used as the surrogate for the radionuclides in the wastes, demonstrated an extremely strong affinity for the slag product. Although slag temperatures as low as 1,250 C were recorded when melting the RWMC soil, temperatures in excess of 1,600 C were necessary to achieve the fluidity required for a successful slag tap

    A broad spectrum of environmental and reclamation issues associated with mine development were discussed at this conference along with rehabilitation of lands disturbed by resource exploration; metal, placer and coal mining; and, sand and gravel quarries. Research has shown that it is possible to minimize or eliminate environmental damage, even in challenging terrain, by using appropriate remedial methods such as revegetation, reforestation, soil conservation, resloping, and recontouring of the soil to return the ecosystem to a natural self-sustaining state. It was noted that revegetation and reforestation efforts typically involves the selection of appropriate species that will adapt to climatic and local soil conditions. The conference featured 21 presentations, of which 4 have been indexed separately for inclusion in this database. refs., tabs., figs

    Full Text Available In this article, there were presented the results of research on combined mechanical and thermal regeneration of waste moulding sand with furfuryl resin originated from one of national foundries manufacturing aluminium alloys castings. Attempts of mechanical reclamation were led on the REGMAS reclaimer enabling to realize preliminary and primary reclamation with use of two modes of mechanical interactions on waste moulding sand. In the first attempt the reclaimer worked without any additional regenerating elements, and as the second solution, the reclaimer operated with additional crushing and abrasive elements to increase the result of primary reclamation. Thermal reclamation was led in the prototypic thermal reclaimer, enabling to fully control the process of grain matrix recovery. As a result of completed investigations the small efficiency of mechanical reclamation was determined. However, use of combined regeneration allowed for obtaining grain matrix of high purity. Thermal regeneration was conducted in prototypic thermal reclaimer. Evaluation of reclaim (reclaimed material quality was carried out in the way of iginition losses and grain-size analysis, surface morphology and also by executing of strength testing of moulding sand prepared on obtained grain matrix for the particular reclamation operations.

    This case study details reclamation planning for the Flatiron Companies' South Boulder Creek Park Project in Boulder, Colorado. The site contains a deposit of high-quality sand and gravel considered to be one of the best and largest known deposits of aggregate materials in the Front Range area. The aggregate deposit is located in a highly visible site just off the Denver-Boulder Turnpike at the entrance to the city from Denver, and adjacent to a residential portion of the city. In order to make maximum use of pre-mining planning, as a tool for resolving a conflict over the company's proposed operation, an extensive cooperative planning effort was initiated. This included the preparation of an environmental impact assessment, numerous public hearings, operating and reclamation plan review by city authorities, annexation of the site to the city, and the granting of a scenic easement on the property to the city for the development of a regional recreation park. A suite of contractual agreements was worked out among Flatiron Companies, the City of Boulder, the Colorado Open Lands Foundation, and the Federal Bureau of Outdoor Recreation. The purpose of this case study is to allow the planner to gain insight into the procedures, possibilities, and constraints involved in premining planning in a cooperative situation.

    1978-12-01

    Thermoluminescent materials have been used in radiation dosimetry for many years, but their application to nationwide personnel dosimetry has been scarce. An undertaking of this nature requires that methods be established for identification of dosimeters and for fast interpretation and communication of dose to the users across the country. It is also necessary that records of cumulative dose of individual radiation workers be continuously updated, and such records be maintained for a prolonged period. To do this many problems pertinent to associated equpment, vis. the computer, TL reader, their interfacing, and to the operational procedures of the service had to be resolved. Since April 1977, the Radiation Protection Bureau has been providing a Thermoluminescent Dosimetry Service to Canadian radiation workers. This document describes the RPB dosimeter, its characteristics, various aspects of the service, objectives of the service, and how the objective goals of the service are achieved. (auth)

    The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m 3 , while extended aeration (EA) and advanced reclamation treatment require 1.2 kWh per m 3 . The energy represents around 40% of the OPEX in MBRs. In terms of CAPEX, the implementation costs of a CAS facility followed by conventional water reclamation treatment (physical-chemical + sand filtration + disinfection) ranged from 730 to 850 €.m -3 d, and from 1,050 to 1,250 €.m -3 d in the case of advanced reclamation treatment facilities (membrane filtration) with a capacity of 8,000 to 15,000 m 3 d -1 . The MBR cost for similar capacities ranges between 700 and 960 €.m -3 d. This study shows that MBRs that have been recently installed represent a cost competitive option for water reuse applications for medium and large capacities (over 10,000 m 3 d -1 ), with similar OPEX to EA and conventional water reclamation treatment. In terms of CAPEX, MBRs are cheaper than EA, followed by advanced water reclamation treatment.

    This report contains a set of recommendations prepared by Oak Ridge National Laboratory (ORNL) for the US Bureau of the Census pertaining to technology innovation and management. Technology has the potential to benefit the Bureau's data collection, capture, processing, and analysis activities. The entire Bureau was represented from Decennial Census to Economic Programs and various levels of Bureau management and numerous experts in technology. Throughout the Bureau, workstations, minicomputers, and microcomputers have found their place along side the Bureau's mainframes. The Bureau's new computer file structure called the Topologically Integrated Geographic Encoding and Referencing data base (TIGER) represents a major innovation in geographic information systems and impressive progress has been made with Computer Assisted Telephone Interviewing (CATI). Other innovations, such as SPRING, which aims to provide Bureau demographic analysts with the capability of interactive data analysis on minicomputers, are in the initial stages of development. Recommendations fall into five independent, but mutually beneficial categories. (1) The ADP Steering Committee be disbanded and replaced with The Technology Forum. (2) Establishment of a Technology Review Committee (TRC), to be composed of technology experts from outside the Bureau. (3) Designate technological gurus. These individuals will be the Bureau's experts in new and innovative technologies. (4) Adopt a technology innovation process. (5) Establish an Advanced Technology Studies Staff (ATSS) to promote technology transfer, obtain funding for technological innovation, manage innovation projects unable to find a home in other divisions, evaluate innovations that cut across Bureau organizational boundaries, and provide input into Bureau technology analyses.

    2013-04-01

    The reclamation of degraded soils adding waste amendments can add significant concentrations of Pb. Because of this, it is important to know the sorption capacity of Pb by the soils where wastes with high concentrations of this metal are applied. To determine the sorption capacity of Pb by mine soils, before and after reclamation treatments, four different sites were selected at a settling pond mine zone: an untreated one as the control sample (B1), a vegetated one with pines for 21 years (B2v), a vegetated with eucalyptus for 6 years (B3v) and an amended with sewage sludges and paper mill residues for 5 months (B4w). All soils had one horizon except B4w, where twice were sampled (B4Aw and B4Bw). The B4Bw is considered analogous of the control soil. To evaluate the sorption capacity by the soils, sorption isotherms were constructed using single-metal solutions of Pb2+ nitrates (0.03, 0.05, 0.08, 0.1 and 0.5 mmol L-1) containing 0.01 M NaNO3 as background electrolyte (Vega et al., 2009). The overall capacity of the soil to sorb Pb was evaluated as the slope Kr (Vega et al., 2008). The obtained results show that the sorption isotherm of Pb by control soil (B1) and its analogous (B4Bw) are of L-type curve, whereas the sorption isotherms of the treated soils (B2v, B3v and B4Aw) are of H-type curve (Giles et al., 1974). The most of the obtained isotherms do not fit with the models of Langmuir or Freundlich, therefore sorption capacity was evaluated by Kr parameter. According to the obtained Kr parameter, B1 and B4Bw have the lowest Pb sorption capacity (Kr = 0.480 and 0.556, respectively), which increased two times after recently waste amending (B4Aw; Kr = 0.998). The vegetated sites (B2v and B3v) also have higher sorption capacity than B1, but lower than B4Aw (Kr = 0.692 and 0.725, respectively). The highest sorption capacity of Pb by the amended soil is due to its characteristics such as high pH and organic carbon content. This is corroborated by the significantly

  2. Methodology for monitoring land reclamation of coal mining dumps

    Val, C.; Gil, A.

    1994-01-01

    The main objective of reclaiming coal mining dumps is to create a stable and self-sustaining land surface that can, in the long term, be put to some productive use. The relationship that is established between the soil and vegetation is the starting point for the newly created ecosystem to enter into a dynamic evolution. In order to know this evolution, it is necessary to develop a methodology for monitoring systematically the reclaimed surfaces. This monitoring methodology should make it feasible to continuously evaluate the obtained results and serve to clarify the potential uses of the reclaimed lands. This paper explains a monitoring methodology implemented at the mining waste dump at the Puentes Mine in Spain. It consists of the selection of 11 plots on the basis of the time the spoils have been exposed to weathering, the type of reconstructed soils, the reclamation system applied, and the revegetation success. Furthermore, an attempt was made to include every possible situation in the dump. Over a period of 3 years, the evolution of the physicochemical conditions of the reconstructed soils, the soil organisms, the herbaceous species, mycorrhizae, tree species, and vertebrates in these plots were studied. The paper also defines the parameters that need to be controlled within each phase of the study. The results obtained reveal the necessity to place the spoils selectively in the dump, the possibilities offered by the ashes as amendments, and the importance of applying organic fertilizers, seeding herbaceous species as a first phase, selecting tree species, and introducing the vertebrates, soil organisms, and mycorrhizae gradually

    The Land Reclamation Program will address the need for coordinated applied and basic research into the physical and ecological problems of land reclamation, and advance the development of cost-effective techniques for reclaiming and rehabilitating mined coal land to productive end uses. The purpose of this new program is to conduct integrated research and development projects focused on near- and long-term reclamation problems in all major U.S. coal resource regions including Alaska and to coordinate, evaluate, and disseminate the results of related studies conducted at other research institutions. The activities of the Land Reclamation Laboratory program will involve close cooperation with industry and focus on establishing a comprehensive field and laboratory effort. Research demonstration sites will be established throughout the United States to address regional and site-specific problems. Close cooperation with related efforts at academic institutions and other agencies, to transfer pertinent information and avoid duplication of effort, will be a primary goal of the program. The major effort will focus on the complete coal extraction/reclamation cycle where necessary to develop solutions to ameliorating the environmental impacts of coal development. A long-range comprehensive national reclamation program will be established that can schedule and prioritize research activities in all of the major coal regions. A fully integrated data management system will be developed to store and manage relevant environmental and land use data. Nine research demonstration sites have been identified.

    Full Text Available Tailings are what’s left over from mining. The rock where copper, gold, silver and other minerals found is ground up into fine particles so that the valuable material can be taken out and refined. The solid waste would affect the environment physically and biologically. Characteristics of tailing are high porosity with low water holding capacity, poor organic matter, poor macro and micro nutrients and no microorganism activity. Therefore, it takes time and requires strategy to manage and change them to a more productive area. Many technologies have been applied to rehabilitate tailing for agriculture. The technologies including the use of manure, compost, mulch, biosolid, chemical fertilizer, microorganism (bacteria, mycorhiza and phytoremediation. Phytoremediation is the use of plants to remediate selected contaminants in the contaminated soil, sludge, sediment, water (ground, surface, waste water. Phytoremediation encompasses a number of different methods that can lead to contaminant degradation, removal or immobilization. Those methods including phytodegradation/rhizodegradation, phytoextraction, phytovolatilization and phytostabilization. The phytoextraction is inexpensive compared with the conventional technology. Some forages have been used for phytoremediation such as Paspalum notatum (Bahia grass, Vetiveria zizonoides (Vetiver grass, Cynodon dactylon (Bermuda grass, since they have been known as heavy metal hyperaccumulator plant.

  6. Inventory of past DOE land disturbance, Yucca Mountain, Nevada, and estimated general reclamation costs

    International Nuclear Information System (INIS)

    1989-04-01

    Since 1976, DOE preliminary investigations for a high level nuclear waste repository at Yucca Mountain, Nevada, have caused widespread disturbances of the landscape. This report addresses the areal extent of those disturbances that have accrued up to June 1988, and identifies expected associated reclamation costs. It was first necessary to identify disturbances, next to classify them for reclamation purposes, and, then, to assign general reclamation costs. The purposes of the analysis were: (1) to establish the amount of disturbance that already exists in the area of Yucca Mountain in order to identify alterations of the landscape that comprise the existing baseline conditions; (2) to identify estimated general reclamation costs for repair of the disturbances; (3) to provide information needed to establish disturbance models, and eventually environmental impact models, that can be applied to future DOE activities during Site Characterization and later phases of repository development, if they occur, and (4) to provide indicators of the needs for reclamation of future disturbances created by DOE's Site Characterization program. Disturbances were estimated using measurements from June 1988, large scale color aerial photography. Two reconnaissance site visits were also conducted. The identified disturbance totals by type are displayed in tabular form in the appendices. 84 refs., 2 figs., 9 tabs

  10. Reclamation and reuse of LEU silicide fuel from manufacturing scrap

    International Nuclear Information System (INIS)

    Gale, G.R.; Pace, B.W.; Evans, R.S.

    2004-01-01

    In order to provide an understanding of the organization which is the sole supplier of United States plate type research and test reactor fuel and LEU core conversions, a brief description of the structure and history is presented. Babcock and Wilcox (B and W) is a part of McDermott International, Inc. which is a large diversified corporation employing over 20,000 people primarily in engineering and construction for the off-shore oil and power generation industries throughout the world. B and W provides many energy related products requiring precision machining and high quality systems. This is accomplished by using state-of-the-art equipment, technology and highly skilled people. The RTRFE group within B and W has the ability to produce various complexly shaped fuel elements with a wide variety of fuels and enrichments. B and W RTRFE has fabricated over 200,000 plates since 1981 and gained the diversified experience necessary to satisfy many customer requirements. This accomplishment was possible with the support of McDermott International and all of its resources. B and W has always had a commitment to high quality and integrity. This is apparent by the success and longevity (125 years) of the company. A lower cost to convert cores to LEU provides direct support to RERTR and demonstrates Babcock and Wilcox's commitment to the program. As a supporter of RERTR reactor conversion from HEU to LEU, B and W has contributed a significant amount of R and D money to improve the silicide fuel process which ultimately lowers the LEU core costs. In the most recent R and D project, B and W is constructing a LEU silicide reclamation facility to re-use the unirradiated fuel scrap generated from the production process. Remanufacturing use of this fuel completes the fuel cycle and provides a contribution to LEU cores by reducing scrap inventory and handling costs, lowering initial purchase of fuel due to increasing the process yields, and lowering the replacement costs.

    2017-06-01

    Full Text Available Metals with an average crustal abundance of <0.01 ppm, which are high in supply shortage due to soaring demand, can, under the excessive environmental risk and <1% recycling rate of their production, be termed as ‘critical’ in a limited geo-boundary. A global trend to the green energy and low carbon technologies with geopolitical scenario is challenging for the sustainable reclamation of these metals from secondary resources. Among the available processes, bio-reclamation can be a sustainable technique for extracting and concentrating these metals. Therefore, in the present paper, the potential reclamation of critical metals (including rare earth elements, precious metals, and a common nuclear fuel element, uranium via their interaction with microbe/s has been reviewed.

  14. Reclamation of oil and gas well sites on privately-owned land in Alberta: An evaluation of benefits and costs

    International Nuclear Information System (INIS)

    Bates, L.A.

    1994-01-01

    In Alberta, ca 24,000 oil/gas well sites will be abandoned over the next 10 years. There is concern that the expense to reclaim the surface lands at these sites to current standards represents a substantial opportunity cost to industry and the provincial economy. The economic costs and benefits associated with regulation of such reclamation activity are examined and the impacts of surface access regulations on the reclamation process are discussed. Cost benefit analysis is not easily applied to environmental regulation where some extra-market benefits and costs are intangible and/or unmeasurable. Although this qualifies the results, it appears that the costs of wellsite reclamation exceed the benefits. Costs are defined as reclamation expenses; benefits are defined as the real estate value of the land, or the net present value of agricultural land rentals. An effort has been made to provide a proxy for the extra-market value of the land to the landowner. The continuation of full surface access compensation for nonproducing wells can result in negative incentive effects that reduce allocative efficiency of reclamation regulation. Reclamation costs are correlated with well age and surface access payments, but not with agricultural land use or geographic region. This suggests that reclamation standards designed to reclaim well sites to the same productive capacity as site-adjacent land is not driving reclamation effort. Rather, landowners have negotiated substantial annual surface lease payments and may also be demanding greater reclamation effort, either to maximize compensation due to higher expectations. Methods of reducing these negative incentive effects to better achieve reclamation goals are suggested. 49 refs., 9 figs., 17 tabs

  15. Determination of Parameters of the Moulding Sand Reclamation Process, on the Thermal Analysis Bases

    Directory of Open Access Journals (Sweden)

    Łucarz M.

    2014-10-01

    Full Text Available For the practical and functional reasons the investigation of the thermal decomposition process is of an essential meaning in relation to the thermal stabilisation of materials and obtaining for them the desired thermal properties. On the other side, thermal tests are carried out in order to identify degradation mechanisms, which is important in the environment protection context, including materials reuse. The cycle of investigations in which thermal TG-DTA methods were applied as supplementary ones for the works on the optimisation of the thermal reclamation process is presented in the hereby paper. The thermal reclamation process as a utilisation method of spent moulding and core sands is more costly than other reclamation methods, but in the majority of cases it simultaneously provides the best cleaning of mineral matrices from organic binders. Thus, the application of the thermal analysis methods (TG-DTA, by determining the temperature range within which a degradation followed by a destruction of bounded organic binders in moulding sands, can contribute to the optimisation of the thermal reclamation process and to the limiting its realisation costs.

  16. The influence of aspect on the early growth dynamics of hydroseeded species in coal reclamation areas

    Energy Technology Data Exchange (ETDEWEB)

    Gonzalez-Alday, J.; Marrs, R.H.; Martinez-Ruiz, C. [University of Valladolid, Palencia (Spain)

    2008-08-15

    Question: Does aspect affect hydroseeding success and the development of vegetation during early vegetation establishment on the steep slopes of coal wastes during the reclamation process? Location: Open-pit coal mine near Villanueva de la Pena, northern Spain. Methods: In the first year after hydroseeding, we monitored the dynamics of hydroseeded species in three permanent plots of 20 m{sup 2} on north- and south-facing slopes every two months. Soil properties and weather conditions were also monitored. Aspect was related to total plant cover during early revegetation, and south-facing slopes had the lowest cover. Aspect also influenced the early dynamics of hydroseeded grasses and legumes establishing on these slopes. Grass cover was greater on the north slope throughout the study, but differences in plant cover between north and south slopes appeared later for the legumes. Aspect also affected the relative contribution of both of grasses and legumes to the total plant cover, with grasses dominant on both northern and southern slopes, except during the summer on the southern slope. The species with the greatest difference in cover between the north- and south-facing slopes were Festuca spp., Lolium perenne and Trifolium repens. In coal mine reclamation areas of Mediterranean climates, differences in the development of hydroseeded species depended on the slope of the coal mine reclamation areas, and this information is of importance to managers in selecting species for use in reclamation.

  8. Access road reclamation

    International Nuclear Information System (INIS)

    Manson, T.; Blok, M.

    1997-01-01

    A general review of the measures involved in restoring abandoned access road sites in British Columbia was presented. Permits and licences are needed for the use of crown land for roads used by the petroleum and natural gas industry for exploration activities. However, the regulatory framework for road site reclamation is not well developed. The nature of access road reclamation is very site-specific. Some of the issues that are considered for all reclamation projects include slope stability, water control, revegetation, soil rehabilitation, access management and monitoring. The primary objective of reclaiming access road sites is to return the site to conditions that are equal or better than pre-disturbance conditions. Restoration measures must be approved by BC Environment and by the Department of Fisheries and Oceans where federal fisheries responsibilities are involved. 54 refs., 5 tabs., 3 figs

  9. Reclamation of abandoned mined lands along th Upper Illinois Waterway using dredged material

    Energy Technology Data Exchange (ETDEWEB)

    Van Luik, A; Harrison, W

    1982-01-01

    Sediments were sampled and characterized from 28 actual or proposed maintenance-dredging locations in the Upper Illinois Waterway, that is, the Calumet-Sag Channel, the Des Plaines River downstream of its confluence with the Calumet-Sag Channel, and the Illinois River from the confluence of the Kankakee and Des Plaines rivers to Havana, Illinois. Sufficient data on chemical constituents and physical sediments were obtained to allow the classification of these sediments by currently applicable criteria of the Illinois Environmental Protection Agency for the identification of hazardous, persistent, and potentially hazardous wastes. By these criteria, the potential dredged materials studied were not hazardous, persistent, or potentially hazardous; they are a suitable topsoil/ reclamation medium. A study of problem abandoned surface-mined land sites (problem lands are defined as being acidic and/or sparsely vegetated) along the Illinois River showed that three sites were particularly well suited to the needs of the Corps of Engineers (COE) for a dredged material disposal/reclamation site. Thes sites were a pair of municipally owned sites in Morris, Illinois, and a small corporately owned site east of Ottawa, Illinois, and adjacent to the Illinois River. Other sites were also ranked as to suitability for COE involvement in their reclamation. Reclamation disposal was found to be an economically competitive alternative to near-source confined disposal for Upper Illinois Waterway dredged material.

    Since the 1950s, reclamation of land affected by brown coal mining in the Czech Republic has been conducted. Since this time, there has been significant improvement in quality development of reclamation measures. This paper discussed the results of different studies where technically reclaimed sites as well as naturally developed sites were investigated. The paper discussed the methodology of the study as well as results of succession versus reclamation and next preferences. One of the studies that was examined involved four groups of animals that have a close relation to soil and plant vegetation. These included ground beetles, bugs, molluscs, and birds. This study found that the spontaneously developed sites could be characterized by the same or a higher biodiversity than those technically reclaimed. The second study examined bird nest preferences either to domestic or to exotic trees. The results showed that although exotic trees dominate on reclaimed sites, the birds preferred the domestic trees for nesting. It was concluded that the natural succession could play a significant role within reclamation practices, particularly on those sites where higher species diversity is desirable. 10 refs., 2 figs.

  12. Nanoenhanced Materials for Reclamation of Mine Lands and Other Degraded Soils: A Review

    Directory of Open Access Journals (Sweden)

    Ruiqiang Liu

    2012-01-01

    Full Text Available Successful mine soil reclamation facilitates ecosystem recovery, minimizes adverse environmental impacts, creates additional lands for agricultural or forestry uses, and enhances the carbon (C sequestration. Nanoparticles with extremely high reactivity and deliverability can be applied as amendments to improve soil quality, mitigate soil contaminations, ensure safe land–application of the conventional amendment materials (e.g., manures and biosolids, and enhance soil erosion control. However, there is no report on using nanoenhanced materials for mine soil reclamation. Through reviewing the up-to-date research results on using environment-friendly nanoparticles for agricultural soil quality improvement and for contaminated soil remediation, this paper synthesizes that these nanomaterials with high potentials for mine soil reclamation include zeolites, zero-valent iron nanoparticles, iron oxide nanoparticles, phosphate-based nanoparticles, iron sulfide nanoparticles and C nanotubes. Transport of these particles in the environment and their possible ecotoxicological effects are also discussed. Additionally, this article proposes a practical and economical approach to applying nanotechnology for mine soil reclamation: adding small amounts of nanoparticles to the conventional soil amendment materials and then applying the mixtures for soil quality improvements. Hence the cost of using nanoparticles is reduced and the benefits of both nanoparticles and the conventional amendment materials are harnessed.

    2015-04-01

    This paper describes seven examples of geomorphic reclamation on mined lands of Spain, as solutions for complex environmental problems, by using the GeoFluv method through the Natural Regrade software (Carlson). Of these seven examples, four of them have been partially or totally constructed. Each of them has its own particularities and contributions, becoming innovative geomorphic solutions to existing environmental (ecological, social and economic) problems. The Quebraderos de la Serrana example (Toledo province) allowed a local company to get permission for slate quarrying in a highly ecologically vulnerable area; before that, the permission for extracting rocks had been rejected with a conventional reclamation approach. The Somolinos case is, to this date, the most complete geomorphic reclamation in Spain, and the first one in Europe to have been built by using the GeoFluv method. This restoration has healed a degraded area of about six hectares at the outskirts of the Somolinos hamlet, in a valuable rural landscape of the Guadalajara province. The Arlanza example (Leon province) shows a design which proposes to restore the hydrological connectivity of a coal mine dump which blocked a valley. The Machorro and María Jose examples (Guadalajara province) are allowing kaolin mining to be compatible with the preservation of protected areas at the edge of the Upper Tagus Natural Park (UTNP), in highly vulnerable conditions for water erosion. The Campredó case (Tarragona province) shows an agreement between a mining company, the academia, and the Catalonian Agency of Water, to combine a high standard of geomorphic reclamation with solving problems caused by flooding downstream of a clay mining area. Finally, the Nuria example is also located at the UTNP area; the goals here are to stabilize a large landslide in a waste dump and to minimize the risk of occurrence of flash floods from mining ponds. Additional information on these examples and about the state of art of

    The Reclamation Landscape Model Development Project was initiated in 1991 to develop a modelling framework to assist in oil sands mine reclamation planning. The initial year focused on developing a suite of computer simulation models suitable for evaluating hydrodynamic, water quality and biological conditions of fine-tails bottom lakes that would be capped with a layer of fresh water. That modelling framework was further refined in 1992--93 by incorporating probabilistic capabilities, developing of secondary production and food-chain components, and implementing of a model to simulate contaminant concentrations in the Athabasca River. In 1993--94 the emphasis expanded from a focus solely on developing tools for evaluating wet landscape options to developing an integrated modelling framework capable of evaluating both wet and dry landscape reclamation options. Major components completed in 1993--94 included development of a dry landscape module that includes surface runoff, groundwater seepage, air vapor and bioaccumulation components, a wetlands module to assist in evaluating treatment potential and for optimizing design of wetlands units, and a risk analysis module for quantifying risks to human health and ecological receptors. The Reclamation Landscape Model is a compartment modelling system that consists of a number of stand-alone computer programs that can be run in conjunction with one another or separately. The computer programs that simulate contaminant-fate processes range from simple empirical models to complex, mechanistic, three-dimensional, dynamic models, which are capable of predicting contaminant concentrations in water, soil, air and biota for a wide range of reclamation landscape units. Most of the component models have probabilistic capabilities

    Nelson, L.R.; MacKinnon, M.; Gulley, J.R.

    1993-01-01

    The hot water process for the extraction of bitumen from oil sands leads to the production of large volumes of wastewater and the formation of a large inventory of fine clay tailings. This fine tailings material and its associated water are acutely toxic to various aquatic test organisms during bioassays. An overview is presented of toxicity testing at Syncrude and Suncor, the application of toxicity testing to fine tailings management, and the role in reclamation planning. The main acutely toxic component of the tailings is the polar organic acid fraction, specifically naphthanates. These naphthanates are readily degraded biologically by indigenous microbial populations. Toxicity testing is aimed at assessing the degree of both acute and chronic toxicity and the long term potential for the input of toxins into the environment from various proposed reclamation measures. 28 refs., 6 figs., 2 tabs

    Residual ammonia and pathogenic microorganisms restrict the reclamation and reuse of wastewater treatment plant (WWTP) effluent. An electrochemical system was developed for the simultaneous removal of ammonia and disinfection of actual WWTP effluent. The performance of the electrochemical process on synthetic wastewater at different chloride ion concentrations was also investigated. Results demonstrated that the optimal chloride concentration for ammonia and Escherichia coli (E. coli) removal was 250 mg/L. Successful disinfection of E. coli in actual effluent was achieved at 0.072 Ah/L, but the inverse S-type inactivation curve indicated that there was a competitive consumption of strong oxidants and chloramines working as another disinfectant. A higher electric charge (0.58 Ah/L) was required to simultaneously reduce E. coli and ammonia to levels that meet the reclamation requirements for WWTP effluent. At this electric charge, no trihalomethane, chlorate, or perchlorate in the system was observed, indicating the biological safety of this process. These results demonstrate the potential of this electrochemical process as a tertiary wastewater treatment process for WWTP effluent reclamation purposes.

In recent decades, all coastal provinces and metropolises in China have experienced severe coastal reclamation related to land scarcity caused by rapid economic growth and urbanization. However, the value of coastal wetlands and ecosystems has not been well understood and appreciated until recent development of advantageous methods of restoring reclaimed land to coastal wetlands in many developed countries. The overall objective of this study is to provide detailed spatial and temporal distributions of coastal reclamation; analyze drivers such as coastal economy, population growth, and urbanization; and understand the relationships among the drivers and land reclamation. We used long-term Landsat image time series from 1985 to 2010 in 5-year intervals, in combination with remotely sensed image interpretation and spatial analysis, to map the reclamation status and changes across the coastal region of China. The Landsat images time-series analysis was also conducted to evaluate the effects of the economy, population, and urbanization drivers on coastal reclamation. The analysis results indicated that 754,697 ha of coastal wetlands have been reclaimed across all coastal provinces and metropolises from 1985 to 2010, and the trend increased sharply after 2005. High-intensity coastal reclamation was mainly driven by the booming economy, especially after 2000, associated with urbanization and industrial development in China's coastal region; this was closely correlated with the gross domestic product (GDP) per capita. The continuous large-scale coastal reclamation of its coastal region now means China is facing a great challenge, including the enormous loss of vegetated coastal wetlands, negative environmental effects, and potential disaster risks related to coastal flooding under future change climate

    Full Text Available Pasture degradation is a concern, especially in susceptible sandy soils for which strategies to recover them must be developed. Microbiological and biochemical soil health indicators are useful in the guindace of soil management practices and sustainable soil use. We assessed the success of threePanicum maximum Jacq. cultivars in the reclamation of a pasture in a sandy Typic Acrudox in the northwest of the state of Paraná, Brazil, based on soil health indicators. On a formerly degraded pasture withUrochloa brizantha (Hochst. ex A. Rich. R.D. Webster, a trial with threeP. maximum (cv. Massai, Tanzânia, or Mombaça was conducted. Lime and phosphate were applied at set-up, and mineral N and K as topdressing. A remnant of degraded pasture adjacent to the trial was used as control. Twenty-three chemical, physical, microbiological and biochemical attributes were assessed for the 0-10 cm topsoil. The procedures for reclamation improved most of the indicators of soil health in relation to the degraded pasture, such as soil P, mineral N, microbial biomass C, ammonification rate, dehydrogenase activity and acid phosphatase. CO2 evolution decreased, whereas microbial biomass C increased in the pasture under reclamation, resulting in a lower metabolic quotient (qCO2 that points to a decrease in metabolic stress of the microbial community. The reclamation of the pasture withP. maximum, especially cv. Mombaça, were evidenced by improvements in the microbiological and biochemical soil health indicators, showing a recovery of processes related to C, N and P cycling in the soil.

  11. Diet of desert tortoises at Yucca Mountain, Nevada, and implications for habitat reclamation

    Rakestraw, D.L.; Holt, E.A.; Rautenstrauch, K.R.

    1995-12-01

    The diet of desert tortoises at Yucca Mountain was assessed during 1992 to 1995 using a combination of feeding observations and scat analysis. Feeding observation data (1993 through 1995) showed that tortoises fed on a wide variety of items. The most frequently eaten items were forbs and annual grasses. These two forage groups comprised more than 90% of all bites taken. Analysis of scat (1992 and 1993) also showed that grasses and forbs were the most common groups, making up more than 80% of the composition of scat. Yearly differences between proportions of species in the diet were observed and were most likely attributable to differences in plant productivity, which is linked to rainfall patterns. Non-native species were an important component of the diet in all years, accounting for 13 to 50% of all bites observed and 6 to 24% of scat contents. A list of all items encountered in the diet is provided. To facilitate reclamation of desert tortoise habitat disturbed by the Yucca Mountain Site Characterization Project, native forage species that should be included in reclamation seed mixes, when feasible, were identified. Although shrubs make up only a small proportion of the diet, they should also be included in reclamation efforts because they provide habitat structure. Tortoise cover sites, and microhabitats amenable to seed germination and seedling establishment. In addition, non-native species should not be planted on reclaimed sites and, if necessary, sites should be recontoured and soil compaction reduced prior to planting

  12. Application of dry stackable tailings technologies : providing the base for reclamation

    The tailings containment structures are some of the largest man made features on the planet. This presentation demonstrated that dry stackable tailings technology may reduce the volume of the accumulated fluid fine tailings. Dry stackable tailings can contribute to boreal forest reclamation and reduce water requirement from the Athabasca River. Much of the water used for the production of each barrel of bitumen is recycled. The water is tied up in the pore spaces of the mineral sand, silt, and clay component which forms the mature fine tailings (MFT) that are contained behind large dykes. Syncrude and Suncor have used a wide variety of technologies to create a dry stackable tailings from this fluid fine tailings substrate. The availability of dry stackable tailings will open options for reclamation strategies that end with the original wetlands or boreal forest. Some of the tailings management options that would lead to a dry stackable tailings naturally also significantly decrease the barrels of water lost with each barrel of bitumen production. These options were discussed along with an analysis of their impact on recycle and pore water quality and quantity. There is an opportunity to remove residual bitumen during the transfer of fluid fine tailings to recover water and create dry stackable tailings. If this bitumen removal is extensive enough, it might be possible to use the dry stackable tailings directly as a reclamation material. tabs., figs.

  13. Can we build better compost? Use of waste drywall to enhance plant growth on reclamation sites.

    2013-11-15

    Compost is a readily available source of organic matter and nutrients and is produced large scale in many jurisdictions. Novel advancements in composting include addition of construction waste, such as drywall, to address its disposal while potentially improving compost quality for use in land reclamation. Varying compositions (15-30% by weight) of coarse and ground waste drywall were added to manure and biosolids during composting. Six composts were applied at four rates (0, 50, 100, 200 Mg ha(-1)) to three reclamation soils (agricultural, urban clean fill, oil sands tailings). Response to composts was assessed in the greenhouse with three plant species (Hordeum vulgare L. (barley), Agropyron trachycaulum (Link) Malte (slender wheat grass) and Festuca saximontana Rydb. (rocky mountain fescue). Drywall added to biosolids or manure during composting had no detrimental effects on vegetation; any negative effects of compost occurred with and without drywall. In agricultural soil and clean fill, biosolids composts with 15% coarse and 18% ground drywall improved native grass response, particularly biomass, relative to biosolids compost without drywall. Drywall manure composts reduced native grass response relative to manure compost without drywall. Only low quality tailings sand was improved by 30% coarse drywall. Compost rate significantly affected above and below ground biomass in agricultural soil and reduced performance of native species at highest rates, suggesting a threshold beyond which conditions will not be suitable for reclamation. Grinding drywall did not significantly improve plant performance and use of coarse drywall would eliminate the need for specialized equipment and resources. This initial research demonstrates that drywall composts are appropriate soil amendments for establishment of native and non native plant species on reclamation sites with consideration of substrate properties and plant species tolerances to dictate which additional feed

    LaFevers, J.R.; Johnson, D.O.; Dvorak, A.J.

    1976-12-01

    This study, sponsored by the U.S. Energy Research and Development Administration, addresses the environmental implications of extraction of coal in North Dakota. These implications are supported by details of the geologic and historical background of the area of focus, the lignite resources in the Fort Union coalfield portion. The particular concentration is on the four-county area of Mercer, Dunn, McLean, and Oliver where substantial coal reserves exist and a potential gasification plant site has been identified. The purposes of this extensive study are to identify the land use and environmental problems and issues associated with extraction; to provide a base of information for assessing the impacts of various levels of extraction; to examine the economics and feasibility of reclamation; and to identify research that needs to be undertaken to evaluate and to improve reclamation practices. The study also includes a description of the physical and chemical soil characteristics and hydrological and climatic factors entailed in extraction, revegetation, and reclamation procedures.

  15. Surface Mining and Reclamation Effects on Flood Response of Watersheds in the Central Appalachian Plateau Region

    2009-01-01

    Surface mining of coal and subsequent reclamation represent the dominant land use change in the central Appalachian Plateau (CAP) region of the United States. Hydrologic impacts of surface mining have been studied at the plot scale, but effects at broader scales have not been explored adequately. Broad-scale classification of reclaimed sites is difficult because standing vegetation makes them nearly indistinguishable from alternate land uses. We used a land cover data set that accurately maps surface mines for a 187-km2 watershed within the CAP. These land cover data, as well as plot-level data from within the watershed, are used with HSPF (Hydrologic Simulation Program-Fortran) to estimate changes in flood response as a function of increased mining. Results show that the rate at which flood magnitude increases due to increased mining is linear, with greater rates observed for less frequent return intervals. These findings indicate that mine reclamation leaves the landscape in a condition more similar to urban areas rather than does simple deforestation, and call into question the effectiveness of reclamation in terms of returning mined areas to the hydrological state that existed before mining.

    The main challenges faced in the reclamation of severely degraded lands are in the management of the systems and finding plant species that will grow under the harsh conditions common in degraded soils. This is especially important in extremely adverse situations found in some substrates from mining activities or soils that have lost their upper horizons. Under these conditions, recolonization of the area by native vegetation through natural succession processes may be extremely limited. Once the main physical and chemical factors restrictive to plant growth are corrected or attenuated, the introduction of leguminous trees able to form symbioses with nodulating N₂-fixing bacteria and arbuscular mycorrhizal fungi constitutes an efficient strategy to accelerate soil reclamation and initiate natural succession. These symbioses give the legume species a superior capacity to grow quickly in poor substrates and to withstand the harsh conditions presented in degraded soils. In this article we describe several successful results in Brazil using N₂-fixing legume tree species for reclamation of areas degraded by soil erosion, construction and mining activities, emphasizing the potential of the technique to recover soil organic matter levels and restore ecosystem biodiversity and other environmental functions.

  17. Grasshopper sparrow reproductive success and habitat use on reclaimed surface mines varies by age of reclamation

    Wood, Petra; Ammer, Frank K.

    2015-01-01

    We studied 3 mountaintop mining–valley fill (MTMVF) complexes in southern West Virginia, USA to examine grasshopper sparrow (Ammodramus savannarum pratensis) demographic response to different age classes of mine land reclamation. For 71 nests monitored during the 2001–2002 breeding seasons, overall nest success (36%) was within the range of nest success rates previously reported for this species, but it was highest on more recently reclaimed sites (56%). Nest density and clutch size did not differ (P > 0.30) among reclamation age classes, whereas number of fledglings was greater (P = 0.01) on more recently reclaimed sites. We measured vegetation variables at 70 nest subplots and at 96 systematic subplots to compare nest vegetation with vegetation available on the plots. We found that nests occurred in areas with more bare ground near the nest, greater vegetation height–density surrounding the nest site, lower grass height, and fewer woody stems, similar to previous studies. As postreclamation age increased, vegetation height–density and maximum grass height increased, and sericea (Lespedeza cuneata) became more dominant. Nest success declined with increasing vegetation height–density at the nest. The grasslands available on these reclaimed mine complexes are of sufficient quality to support breeding populations of grasshopper sparrows, but nest success decreased on the older reclaimed areas. Without active management, grasslands on reclaimed MTMVF mines become less suitable for nesting grasshopper sparrows about 10 years after reclamation.

    Directory of Open Access Journals (Sweden)

    Harionovskij A.A.

    2017-09-01

    Full Text Available The urgency of the issue of reclamation of disturbed lands is due to the fact that coal mining by both open and underground methods is inevitably accompanied by exclusion from economic circulation and violation of lands for various purposes, by changing the terrain and forming an industrial landscape. The article contains information on the volumes of disturbance and reclamation of lands in the coal industry In the article the directions of reclamation and applied technologies, domestic developments and foreign experience are considered. It was noted that the priority areas for reclamation of disturbed lands in the coal industry are: agricultural, forestry and sanitary-hygienic. It is noted that the quality of the recultivated areas is not always at the proper level, which creates dif culties in their subsequent use. The main reasons for the low quality of reclamation are the lack of the necessary amount of initial data on the composition and properties of soil and rock mass of the dumps at the development stage of the reclamation projects, the lack of special technical means for performing remediation works at a high level, the lack of a landscape approach to the restoration of disturbed areas. Measures to prevent spontaneous combustion of rock dumps are laid in projects and are not implemented in practice in full, which leads to the occurrence of res. Two new developments in the eld of reclamation are presented: the microbiological method developed by MNIIECO TEK JSC, and the method for restoring the biological productivity of disturbed lands, proposed by the Scienti c Research Institute of Agricultural Problems of Khakassia SB RAAS. Identi ed problem issues in the eld of reclamation and a list of measures to improve the state of protection of land resources. In the article it is shown that in order to improve the state in the sphere of land resources protection in the coal industry, it is necessary to improve the applied mining technologies

  9. Role of the Bureau of Radiological Health in controlling radioactivity in consumer products

    International Nuclear Information System (INIS)

    Neill, R.H.

    1978-01-01

    Under authority provided by the Public Health Service Act, the Bureau of Radiological Health may cooperate with State and local authorities on matters relating to the preservation and improvement of the public health. Within the Bureau, the Division of Radioactive Materials and Nuclear Medicine is responsible for the development of a comprehensive radioactive materials control program, including user protection at the State and Federal levels. The objective of radiological health programing is to protect or minimize exposure as a presumptive index for somatic injuries and to minimize the deterioration of the genetic constitution of the population. To achieve this objective, there must be consistent, uniform, and all-inclusive control of radioactive materials. A brief history of past uses of some radioactive materials is presented. Since the authority of the Nuclear Regulatory Commission to license and control source and byproduct materials does not include naturally occurring and accelerator-produced radioactive materials (NARM), the Bureau's program has concentrated in this area. Recently, in cooperation with other Federal and State radiation control agencies, the Bureau has drafted some guidelines for NARM that will be useful to the states in implementing their programs

    2016-04-01

    The mining production is situated in the several provinces of Ukraine. Specification of the problem coal and mixed sulfide mining activities in Ukraine have resulted in the generation of hundreds of millions of tons of hazardous wastes consisting of rest of manganese and iron oxides, traces of rare elements, sulphur bearing minerals, such as pyrite. These wastes have been / are still deposited, throughout the years, in huge stockpiles and dams. Land restoration in the mining region takes several forms. One of the ways is land reclamation. This way includes forest, recreation and agricultural reclamation. Land reclamation in industrial regions is conducted in one technological cycle with the process of ore mining. The soil mass is taken off, piled up and heaped onto the land after the rock has been replaced. The ecohydrogeological background of reclaimed lands forming and exploration was worked out. It foresee an environment restoration of disturbed lands to manage flow down, atmospheric precipitations taking aside, the process of the reclaimed profile biogenetic horizons formation and promotion with total depth 1.0-1.2 m and involvement of more suitable rocks and artificial drainage building. The effectiveness of different models of land reclamation and heavy metals migration through the rock-soil-plant system was investigated. Field experiments were carried out to study the adaptive potential of plants having different requirements for substrate fertility, with the main task to assess the prospects of land management for the rocks of the Nikopol manganese basin. The rocks exposed to the surface after manganese ore mining, first technical stage of landscape restoration, and plant melioration stages pass into other geochemical conditions and change their physical-chemical properties. During long-term melioration crops have dramatically improved some processes as following: bioweathering of rocks, phytomeliorated rocks fertility growth, etc. Meantime some rocks

    Houghton, R.L.; Anderson, G.S.; Hill, S.R.; Burgess, J.L.; Wald, J.D.; Patrick, D.P.; Hall, R.L.; Unseth, J.D.

    1987-01-01

    About 590,000 pounds of uranium oxide were recovered from 85,000 tons of lignite in at least 16 North Dakota pits between 1955 and 1967. Because uranium salts in the overburden generally were not recovered, spoil piles at abandoned mine sites contain elevated uranium contents. Reclamation of these mines is required to eliminate public hazards due to elevated radiation and toxic-element levels. A pilot reclamation project was implemented at one abandoned mine pit in northwestern Stark County. Basically, the reclamation involved the replacement of spoil material into the pits from which it was removed. Based on analyses of drill-hole cutting samples obtained from 2-foot depth increments on a 50-foot grid over the 7.25-acre spoil pile, spoil material with radium-226 concentrations exceeding 5 picocuries per gram above background or with uranium concentrations exceeding 5 times background was identified and mapped in three dimensions. This ''most-contaminated'' spoil material was selectively replaced in the mine pits above the water table to prevent dissolution of uranium salts and under a minimum of 5 feed of cover to minimize postreclamation surface-radiation levels. Similarly, areas of spoils with specific conductance greater than 5,000 microsiemens per centimeter were replaced at least 6 feet below the postreclamation ground surface to promote revegetation and above the water table to prevent enrichment of dissolved-solids concentrations in the aquifer. Finally, replaced zones of high radioactivity and soluble salts were capped with clay from the base of an adjacent pit; and the surface topography was mounded to minimize infiltration that might introduce radioactive and other soluble salts into the aquifer

  15. ENHANCEMENT OF TERRESTRIAL CARBON SINKS THROUGH RECLAMATION OF ABANDONED MINE LANDS IN THE APPALACHIAN REGION

    Energy Technology Data Exchange (ETDEWEB)

    Gary D. Kronrad

    2002-12-01

    The U.S.D.I. Office of Surface Mining (OSM) estimates that there are approximately 1 million acres of abandoned mine land (AML) in the Appalachian region. AML lands are classified as areas that were inadequately reclaimed or were left unreclaimed prior to the passage of the 1977 Surface Mining Control and Reclamation Act, and where no federal or state laws require any further reclamation responsibility to any company or individual. Reclamation and afforestation of these sites have the potential to provide landowners with cyclical timber revenues, generate environmental benefits to surrounding communities, and sequester carbon in the terrestrial ecosystem. Through a memorandum of understanding, the OSM and the U.S. Department of Energy (DOE) have decided to investigate reclaiming and afforesting these lands for the purpose of mitigating the negative effects of anthropogenic carbon dioxide in the atmosphere. This study determined the carbon sequestration potential of northern red oak (Quercus rubra L.), one of the major reclamation as well as commercial species, planted on West Virginia AML sites. Analyses were conducted to (1) calculate the total number of tons that can be stored, (2) determine the cost per ton to store carbon, and (3) calculate the profitability of managing these forests for timber production alone and for timber production and carbon storage together. The Forest Management Optimizer (FORMOP) was used to simulate growth data on diameter, height, and volume for northern red oak. Variables used in this study included site indices ranging from 40 to 80 (base age 50), thinning frequencies of 0, 1, and 2, thinning percentages of 20, 25, 30, 35, and 40, and a maximum rotation length of 100 years. Real alternative rates of return (ARR) ranging from 0.5% to 12.5% were chosen for the economic analyses. A total of 769,248 thinning and harvesting combinations, net present worths, and soil expectation values were calculated in this study. Results indicate that

    2014-01-01

    The growing concern about the effectiveness of reclamation strategies has motivated the evaluation of soil properties following reclamation. Recovery of belowground microbial community is important for reclamation success, however, the response of soil bacterial communities to reclamation has not been well understood. In this study, PCR-based 454 pyrosequencing was applied to compare bacterial communities in undisturbed soils with those in reclaimed soils using chronosequences ranging in time following reclamation from 1 to 20 year. Bacteria from the Proteobacteria, Chloroflexi, Actinobacteria, Acidobacteria, Planctomycetes and Bacteroidetes were abundant in all soils, while the composition of predominant phyla differed greatly across all sites. Long-term reclamation strongly affected microbial community structure and diversity. Initial effects of reclamation resulted in significant declines in bacterial diversity indices in younger reclaimed sites (1, 8-year-old) compared to the undisturbed site. However, bacterial diversity indices tended to be higher in older reclaimed sites (15, 20-year-old) as recovery time increased, and were more similar to predisturbance levels nearly 20 years after reclamation. Bacterial communities are highly responsive to soil physicochemical properties (pH, soil organic matter, Total N and P), in terms of both their diversity and community composition. Our results suggest that the response of soil microorganisms to reclamation is likely governed by soil characteristics and, indirectly, by the effects of vegetation restoration. Mixture sowing of gramineae and leguminosae herbage largely promoted soil geochemical conditions and bacterial diversity that recovered to those of undisturbed soil, representing an adequate solution for soil remediation and sustainable utilization for agriculture. These results confirm the positive impacts of reclamation and vegetation restoration on soil microbial diversity and suggest that the most important

  17. The study of the impact for social culture toward the planning of reclamation for Benoa Bay in Bali

    2017-05-01

    This study aims to examine the impact of social culture on the planning of reclamation for Benoa Bay in Bali. This study began with a discussion about the process to get a license for the reclamation of Benoa Bay, and then discussed the impact on social culture, especially for the contamination of traditional holy places (places where are used for Balinese Hindus' religious rituals and customs). This study used a descriptive method with regulation, legislative, and literature approaches. The result of this study was recorded, analyzed, interpreted and compiled in the form of a paper. From the results of this study, the authors concluded that the process to get a license ignored the environment, and paid no attention to socialization and the communication of information about the developmental planning of reclamation in Benoa Bay in Bali. From the aspect of social culture, the traditional holy places for Balinese Hindus will be contaminated.

    The article considers the methodological and practical aspects of reclamation of landfills and dumps of municipal solid waste in a waste management system. The general tendencies of system development in the context of elements of the international concept of waste hierarchy are analyzed. Statistics of the formation and burial of domestic waste indicate a strategic non-alternative to the rejection of landfill technologies in favor of environmentally, energy efficient and economically expedient ways of utilization of municipal waste as a world trend. Practical approaches to the study of territories on which there are dumps and landfills are considered to justify the design solutions for reclamation.

  19. The use of some geochemical methods in evaporation pond reclamation assessments

    Certain geochemical techniques, such as complete inorganic identification, rare earth fingerprints, and the use of chondrite plots that may be used over and above CCME (Canadian Council of Ministers of the Environment) standards in the reclamation of evaporation ponds, are described. These techniques permit the separation of contaminant elements that occur naturally beyond provincial or CCME standards. They also permit conclusions to be drawn about soil stratification around the lagoons. The methods are less costly yet more effective than conventional assessment methods. Use of these techniques is illustrated with an example from an Alberta gas plant. 7 refs., 6 tabs., 5 figs

    2015-01-01

    Relative efficiency of gypsum, potassium silicate and their combinations at different levels for reclamation of saline sodic soil was tested. Treatments were replicated thrice. All pots were arranged according to completely randomized design and treatments were applied to the soil according to treatment plan. Appropriate time was given to achieve the reclamation of saline sodic soil and relative efficiency was assessed through laboratory analysis. After this, rice seedling (Shaheen Basmati) was transplanted in all the pots i.e., 3 plants per pot. Necessary N, P and K fertilizers were applied at the recommended rate. After crop harvest, soil samples were taken for analysis of pH, electrical conductivity (EC), sodium adsorption ratio (SAR) and exchangeable sodium percentage (ESP) of soil. All the amendments when used alone or in combination with each other improved the chemical parameters of soil. All levels of gypsum (100%, 75% and 50% G.R) proved effective in lowering pH, EC, SAR and ESP of saline sodic soil. Similar trend was observed with the use of all levels of potassium -1 silicate (225, 150 and 75mg per kg soil) of soil. Combinations of gypsum and potassium silicate also remained better in this regard. The most effective treatment was application of the full required rate of gypsum. (author)

  1. Impact of direct greenhouse gas emissions on the carbon footprint of water reclamation processes employing nitrification-denitrification.

    Science.gov (United States)

    Schneider, Andrew G; Townsend-Small, Amy; Rosso, Diego

    2015-02-01

    Water reclamation has the potential to reduce water supply demands from aquifers and more energy-intensive water production methods (e.g., seawater desalination). However, water reclamation via biological nitrification-denitrification is also associated with the direct emission of the greenhouse gases (GHGs) CO₂, N₂O, and CH₄. We quantified these direct emissions from the nitrification-denitrification reactors of a water reclamation plant in Southern California, and measured the (14)C content of the CO₂ to distinguish between short- and long-lived carbon. The total emissions were 1.5 (±0.2) g-fossil CO₂ m(-3) of wastewater treated, 0.5 (±0.1) g-CO₂-eq of CH₄ m(-3), and 1.8 (±0.5) g-CO₂-eq of N₂O m(-3), for a total of 3.9 (±0.5) g-CO₂-eqm(-3). This demonstrated that water reclamation can be a source of GHGs from long lived carbon, and thus a candidate for GHG reduction credit. From the (14)C measurements, we found that between 11.4% and 15.1% of the CO₂ directly emitted was derived from fossil sources, which challenges past assumptions that the direct CO₂ emissions from water reclamation contain only modern carbon. A comparison of our direct emission measurements with estimates of indirect emissions from several water production methods, however, showed that the direct emissions from water reclamation constitute only a small fraction of the plant's total GHG footprint.

    1998-12-31

    The use of post-mining reclamation ponds for the production of freshwater shrimp was evaluated by examining different stocking densities. Juvenile shrimp (Macrobrachium rosenbergii) averaging 0.5g each were stocked into four existing ponds at Peabody`s Ken Surface Mine at 6,175; 12,350; 18,500; and 24,700/ha (2,500, 5,000, 7,500, and 10,000/acre) on June 1, 1995. Shrimp were fed twice a week for 103 days, with harvest conducted September 13, 1995. Survival averaged 40%, overall. Average individual weight size was inversely related to stocking density ranging from 52 g (8.7 shrimp/lb) at 6,175/ha to 20.3 g (22.7 shrimp/lb) at 18,500/acre. Total production was directly related to stocking density ranging from 97 kg/ha (86 lbs/acre) at low density to 211 kg/ha (188 lbs/acre) at 18,500/ha shrimp acre. The major difficulty was at harvest due to difficulty in draining ponds. Construction of designed culture ponds with gravity drains during reclamation could greatly enhance survival, harvestability, and commercial feasibility.

    2016-12-01

    This paper describes an effective approach to select suitable plant species for reclamation of mined lands in Chadormaloo iron mine which is located in central part of Iran, near the city of Bafgh in Yazd province. After mine's total reserves are excavated, the mine requires to be permanently closed and reclaimed. Mine reclamation and post-mining land-use are the main issues in the phase of mine closure. In general, among various scenarios for mine reclamation process, i.e. planting, agriculture, forestry, residency, tourist attraction, etc., planting is the oldest and commonly-used technology for the reclamation of lands damaged by mining activities. Planting and vegetation play a major role in restoring productivity, ecosystem stability and biological diversity to degraded areas, therefore the main goal of this research work is to choose proper and suitable plants compatible with the conditions of Chadormaloo mined area, providing consistent conditions for future use. To ensure the sustainability of the reclaimed landscape, the most suitable plant species adapted to the mine conditions are selected. Plant species selection is a Multi Criteria Decision Making (MCDM) problem. In this paper, a fuzzy MCDM technique, namely Fuzzy Analytic Hierarchy Process (FAHP) is developed to assist chadormaloo iron mine managers and designers in the process of plant type selection for reclamation of the mine under fuzzy environment where the vagueness and uncertainty are taken into account with linguistic variables parameterized by triangular fuzzy numbers. The results achieved from using FAHP approach demonstrate that the most proper plant species are ranked as Artemisia sieberi, Salsola yazdiana, Halophytes types, and Zygophyllum, respectively for reclamation of Chadormaloo iron mine.

    2014-12-01

    Full Text Available The article deals with the recent positive changes in the industrial landscape of the Karviná region in a broader context. The Karviná region has been the most important part of the coal-bearing Ostrava-Karviná District. Since the industrial revolution, the position of the primary mining area has brought a dynamic economic development and a great concentration of population into the fast-growing conurbation cities, particularly between 1950s and 1980s. However, the dominant coal mining and processing has had a negative impact on the environment, the character and utilization of the landscape. Many environmental, socioeconomic and other problems did not become fully evident until the social changes at the turn of 1980s and 1990s. At present, a great attention is being paid to the reclamation of the affected landscape. As a result, the region is starting to change its unflattering image of an industrial and problematic area devastated by coal extraction for the better after many years. The various forms of land reclamation, modification of water bodies, construction of new sports and recreational facilities and so on are bringing a gradual improvement of the environment in the region, creating a new cultivated landscape that can be used, among other things, for various forms of tourism and relaxation.

    A range of methods, from simple cost benefits analyses to sophisticated decision making systems, are available for assessing the net countermeasure benefits to man contamination of different environments. As part of the Nordic Nuclear Safety Research Programme, an attempt was made to develop a strategy for mid- and long-term reclamation of contaminated cultivated agricultural environments, animals, forests, freshwater and fish, and urban environments. The study focused on the long-lived nuclides 137 Cs and 90 Sr. Also social implications and a sound environmental management should be addressed in the selection of a countermeasure strategy. The considerations of the cultivated agricultural environment included a model of a Nordic environment, with different soil types, land use and crops. When considering countermeasure strategies for animals, both transfer and production rates have to be compared, as the transfer of radiocaesium to animals in cultivated areas is low compared to the transfer in unimproved areas or to wild animals. The countermeasures considered for freshwater were: use of alternative water supply, and ion exchange method, and for freshwater fish: limiting consumption, brining in households, and wet land and lake liming. In urban environments knowledge on the source strengths, relative dose rate at different locations (indoor, outdoor) due to the deposition on different urban surfaces (roofs, walls, paved areas, trees, bushes etc.) is important. For all environments costs and averted doses were estimated for a fallout scenario giving 1 MBq m -2 of 137 Cs. The effectiveness of the different countermeasures was then compared and reclamation strategies suggested. (author)

    Reclamation is a method of ultimate utilization of land adversely affected by mining or other industrial activity. The paper explains the types of reclamation and the term “optimal reclamation”. Technological options of the long-lasting process of mine dumps reclamation starting with the removal of overlying rocks, transport and backfilling up to the follow-up remodelling of the mine dumps terrain. Technological units and equipment for stripping flow division. Stripping flow solution with respect to optimal reclamation. We recommend that the application of logistic chains and mining simulation with follow-up reclamation to open-pit mines be used for the implementation of optimal reclamation. In addition to a database of local heterogeneities of the stripped soil and reclaimed land, the flow of earths should be resolved in a manner allowing the most suitable soil substrate to be created for the restoration of agricultural and forest land on mine dumps. The methodology under development for the solution of a number of problems, including the geological survey of overlying rocks, extraction of stripping, their transport and backfilling in specified locations with the follow-up deployment of goal-directed reclamation. It will make possible to reduce the financial resources needed for the complex process chain by utilizing GIS, GPS and DGPS technologies, logistic tools and synergistic effects. When selecting machines for transport, moving and spreading of earths, various points of view and aspects must be taken into account. Among such aspects are e.g. the kind of earth to be operated by the respective construction machine, the kind of work activities to be performed, the machine’s capacity, the option to control the machine’s implement and economic aspects and clients’ requirements. All these points of view must be considered in the decision-making process so that the selected machine is capable of executing the required activity and that the use of an

    Full text: Radiation safety at areas affected by the natural uranium mining and milling facilities is very important for the environment protection and human health. For this purpose the close operator-regulator contact is required during remedial operations. One of the key mechanisms of the operating regulatory supervision of radiation safety at uranium legacy sites is organization of independent radiation control and monitoring in the course of reclamation and after its completion. The main stages of this strategy include: detailed radiation survey at the area and in the vicinity of the former uranium mining sites; threat assessment in order to identify the regulatory priorities; environmental radiation control and monitoring. Tailings and shallow disposal sites of the uranium mining wastes are the most critical areas in terms of potential hazard for the environment. Tailings are the source of contamination of the near-land air due to the radionuclide dust resuspension from the tailing surface; surface and ground water due to washing out from by precipitation and surface streams of toxic and radioactive elements. Frequently, contamination of surface and ground waters results in some problems, especially when using the leaching fluids for the solution mining and draining hydraulic fluids. Radiation risk for the residents of areas near not operating uranium mining and milling facilities depends on the following factors: radon exhalation from the surface of dumps and tailing; radioactive dust transfer; using radioactive material in building; contamination of surface water streams and aquifers used for drinking water supply; contamination of open ponds used for fish breeding and catching; contamination of foodstuffs grown in the nuclear legacy areas. Radiation monitoring is necessary for the up-to-date response to changing radiation situation during reclamation and arrangement of adequate countermeasures. We mean here comprehensive dynamic surveillance including long

    The performance of the Sha-he wastewater reclamation plant was evaluated in this study. To remove residual nitrogen after Anaerobic-Anoxic-Oxic (A2O) treatment, three multistage Anoxic-Oxic (A/O) were added to investigate the nitrogen removal efficiency and its mechanism. In addition, the constituents and evolution of dissolved organic matter (DOM) during wastewater reclamation was also investigated using a method combining fluorescence spectroscopy with fluorescence regional integration (FRI). The results suggested that multistage A/O treatment can effectively improve the nitrogen removal ability under low concentrations of carbon sources. The total nitrogen (TN) exhibits significantly positive correlation with fulvic acid-like materials and humic acid-like materials. The correlation coefficient for TN and fulvic acid-like substances (R2 = 0.810, P nitrogen removal may be achieved with the fulvic-like and humic-like substances, and the removal effects were higher by fulvic acid-like substances than humic-like substances, mostly due to that the latter were relatively more difficult to be utilized as carbon source during the nitrogen removal process. The effluent water quality of biological treatment reached the first grade A standard of "Cities sewage treatment plant pollutant discharge standard" (GB18918-2002). In addition, the effluent from the membrane bioreactor reached the "Standards of reclaimed water quality" (SL368-2006).

    Wastewater samples from the secondary clarifier of two treatment plants were spiked in the microgram-to-tens-of-microgram per liter range with diuron (herbicide), ibuprofen and diclofenac (anti-inflammatory drugs), sulfamethoxazole and erythromycin (antibiotics), bezafibrate and gemfibrozil (lipid regulators), atenolol (β-blocker), carbamazepine (anti-epileptic), hydrochlorothiazide (diuretic), caffeine (stimulant) and N-acetyl-4-amino-antipiryne, a metabolite of the antipyretic drug dypirone. They were subsequently ozonated in continuous flow using 1.2L lab-scale bubble columns. The concentration of all spiking compounds was monitored in the outlet stream. The effects of varying ozone input, expressed as energy per unit volume, and water flow rate, and of using single or double column were studied in relation to the efficiency of ozone usage and the ratio of pollutant depletion. The ozone dosage required to treat both wastewaters with pollutant depletion of >90% was in the 5.5-8.5 mg/L range with ozone efficiencies greater than 80% depending on the type of wastewater and the operating conditions. This represented 100-200 mol of ozone transferred per mole of pollutant removed. Direct and indirect environmental impacts of ozonation were assessed according to Life Cycle Assessment, a technique that helped identify the most effective treatments in terms of potential toxicity reduction, as well as of toxicity reduction per unit mass of greenhouse-gas emissions, which were used as an indicator of environmental efficiency. A trade-off between environmental effectiveness (toxicity reduction) and greenhouse-gas emissions was observed since maximizing toxicity removal led to higher greenhouse-gas emissions, due to the latter's relatively high ozone requirements. Also, there is an environmental trade-off between effectiveness and efficiency. Our results indicate that an efficient use of ozone was not compatible with a full pollutant removal.

    Phosphogypsum (PG), a byproduct of the phosphate fertilizer industry, was produced and stockpiled at the Agrium Fort Saskatchewan facility from 1965 to 1991. Upon decommissioning, the outer slopes of the PG stacks were reclaimed by applying 15 cm of topsoil and planting a non-native seed mix. Physical, chemical, and hydrologic evaluations of the cover system confirmed that plants were successfully growing in various soil capping depths and were often rooting more than 200 mm into the PG. Percolation past the substrate into PG during a typical storm event was low (< 10 mm), and runoff from the stacks was negligible. Runoff quality met most guidelines, but some parameters, including fluoride, were up to 18 times higher than provincial or federal guidelines for soil and water quality. However, the cover system, when applied appropriately, does meet basic reclamation objectives. The exceedances are found in areas where the cover system has been compromised by erosion or mixing or in areas where the cover system has not been fully applied, such as roads or the inner basin. In areas where the cover system has been applied successfully, basic reclamation requirements are met.

    Full Text Available Jewish observance of shmita (alternatively spelled shemitah—the sabbatical year, or seventh (sheviit year—is changing. Historically rooted in agriculture, modern Jewish environmentalists are seizing upon the long-ignored environmental and social justice (tikkun olam aspects of shmita as originally described in the five books of Moses, the Torah in the Hebrew Bible, the basis of Jewish law. Primary research was conducted through key-stakeholder interviews with leading American and Israeli Jewish environmentalists and thought leaders. They see shmita as a core Jewish value—one that, like Shabbat, the Jewish sabbath, has the power to transform society. Their work has brought shmita from an obscure law dealt with mainly by Israel’s Orthodox to a new Jewish ethos being discussed across the United States, Europe, Israel, and even on the floor of Knesset, Israel’s parliament. This article also describes shmita as delineated in the Torah and through the rabbinic canon of halacha (Jewish law, and explains shmita practice from biblical times to the present day.

    Full Text Available The research was aimed at assessing the salinity and sodicity effects of two soil types submitted to correction on barley crop. The two soils, contained in cylindrical pots (0.40 m in size and 0.60 m h supplied with a bottom valve for the collection of drainage water and located under shed to prevent the leaching action of rainfall, were clay-textured and saline and sodic-saline at barley seeding, as they had been cultivated for 4 consecutive years with different herbaceous species irrigated with 9 types of brackish water. In 2002-2003 the 2 salinized and sodium-affected soils (ECe and ESP ranging respectively from 5.84-20.27 dSm-1 to 2.83-11.19%, submitted to correction, were cultivated with barley cv Micuccio, and irrigated with fresh water (ECw = 0.5 dS m-1 and SAR = 0.45 whenever 30% of the maximum soil available moisture was lost by evapotranspiration. Barley was shown to be a salt-tolerant species and did not experience any salt stress when grown in soils with an initial ECe up to 11 dS m-1. When it was grown in more saline soils (initial ECe of about 20 dS m-1, despite the correction, it showed a reduction in shoot biomass and kernel yield by 26% and 36% respectively, as compared to less saline soils.

    Dubravka Mlinarić

    2017-01-01

    Full Text Available In the paper the authors are focused on local and trans-border migration processes in Northern Dalmatia and their influence on the economic and demographic development of the Vrana feudal estate during the 17th and 18th century. The research was based on the complex and qualitative analysis of demographic, economical, confessional and cartographic archival sources, followed by the correlation of existing secondary literature research (desk-study analysis. The primary scientific goal was to determine how the land reclamation and corresponding protomodern migrations, which had occurred prior the statistical period of migration registration, have changed and influenced further economic and environmental development of this particular hinterland of the Dalmatian area. The change of the lowland marshy borderlands was investigated within the frames of its physical ambience, geo-strategic position, and its communication, commercial and migratory potential, within the interdisciplinary framework and discourse of ecohistory and environmental studies methodology and approach. In addition, this paper tends to discuss whether the Borelli family's private venture of investing in land reclamation was an economic success or rather an adventurous experiment since they failed to keep the immigrants colonized from Bukovica in permanent settlements. After getting the Vrana estate as a feudal possession in 1752, these Italian family members undertook a huge action of marshland and land reclamation in order to re-evaluate and redefine land use in the area that was once a prosperous Roman barn field, which provided food for a much larger population. Consequently, these newly gained lands were used by the state, along with some other tax and administrative benefits, to attract agrarian labour force. After drying the Vrana moors and marshes, damp soil improved in quality and the excess water was taken away, especially after the trenching of main and collateral ditches

    2009-01-01

    Teck Coal Ltd. operates 6 open-pit coal mines, of which 5 are located in the Elk Valley in southeastern British Columbia. The Fording River Operations (FRO) began in 1971 in mining areas in Eagle Mountain, Turnbull Mountain and Henretta Valley. The recovery of approximately 5 million tons of coal from the Henretta Creek Valley posed significant challenges to mine planners, hydrologists and environmental experts because the coal had to be recovered from the valley flanks and also from under the main valley floor, on which the fish-bearing Henretta Creek runs. The Henretta Dragline Mining project was described along with the water control structures and fisheries management efforts for the cutthroat trout. A detailed Environmental Impact Assessment and Stage 1 mining report for the Henretta Valley area was completed in December 1990. FRO was granted a mining and reclamation permit in 1991. A temporary relocation of 1,270 metres was required in in April 1997 in order to enable mining on both sides and below the creek bed. Among the innovative construction techniques was a diversion of Henretta Creek through large diameter steel culverts and a specialized crossing of the creek to allow fish passage. The first water flowed through the reclaimed Henretta Creek channel in late 1998 and the first high flow occurred in the spring of 2000. Teck coal FRO then launched an annual fish and fish habitat monitoring program which focused on the Henretta Creek Reclaimed Channel and Henretta Lake. This document presented the results from the final year, 2006, and a summary of the 7 year aquatic monitoring program. It was concluded that from mining through to reclamation, the Henretta project shows the commitment and success of mining and reclamation practices at Teck Coal. Indicators of the project's success include riparian zone vegetation, fisheries re-establishment, aquatic communities and habitat utilization by terrestrial and avian species. 33 refs., 1 fig.

  1. Impact of direct greenhouse gas emissions on the carbon footprint of water reclamation processes employing nitrification–denitrification

    Water reclamation has the potential to reduce water supply demands from aquifers and more energy-intensive water production methods (e.g., seawater desalination). However, water reclamation via biological nitrification–denitrification is also associated with the direct emission of the greenhouse gases (GHGs) CO{sub 2}, N{sub 2}O, and CH{sub 4}. We quantified these direct emissions from the nitrification–denitrification reactors of a water reclamation plant in Southern California, and measured the {sup 14}C content of the CO{sub 2} to distinguish between short- and long-lived carbon. The total emissions were 1.5 (± 0.2) g-fossil CO{sub 2} m{sup −3} of wastewater treated, 0.5 (± 0.1) g-CO{sub 2}-eq of CH{sub 4} m{sup −3}, and 1.8 (± 0.5) g-CO{sub 2}-eq of N{sub 2}O m{sup −3}, for a total of 3.9 (± 0.5) g-CO{sub 2}-eq m{sup −3}. This demonstrated that water reclamation can be a source of GHGs from long lived carbon, and thus a candidate for GHG reduction credit. From the {sup 14}C measurements, we found that between 11.4% and 15.1% of the CO{sub 2} directly emitted was derived from fossil sources, which challenges past assumptions that the direct CO{sub 2} emissions from water reclamation contain only modern carbon. A comparison of our direct emission measurements with estimates of indirect emissions from several water production methods, however, showed that the direct emissions from water reclamation constitute only a small fraction of the plant's total GHG footprint. - Highlights: • Direct greenhouse gas emissions were measured at a wastewater reclamation plant. • These greenhouse gas emissions amounted to 3.9 (± 0.5) g-CO{sub 2}-eq m{sup −3} of wastewater. • {sup 14}C analysis of the CO{sub 2} emissions was conducted to determine the fossil component. • 11.4% to 15.1% of the emitted CO{sub 2} was derived from fossil sources.

    Full Text Available In traditional technologies of casting moulds and core production on the basis of high-silica sands with binding agent addition, the reclamation consists mainly of a sand recovery and very seldom of a sand and bentonite recovery.Analysis of data from several countries indicates that from 600 to 1200 kg of fresh sand is used for 1 tonne of ferrous casting alloys. In Poland it is 1000 kg of sand for 1 tonne of castings [1]. Out of this amount approximately 20% of fresh sand is used for core production and the remaining amount for rebounding moulding sands. Analysis of data from 20 largest Polish foundries, performed in 2004 [2] indicates that approximately 50% of waste foundry sands is reclaimed while the rest is directed to dumping grounds. Taking into account all remaining foundries it can be estimated that approximately 250-350 000 tonnes of waste foundry sands are sent to dumping grounds annually.Important issue are costs of storage, which depend on the kind of wastes and on the ownership form of dump-sites (municipal dumpinggrounds, plant’s or own [belonging to the foundry] as well as on their relation to the costs of purchasing fresh sands. Average charges for storage of moulding sands wastes on storage yards in Europe are within the range: 12.5 to 61 Eu, which means from 85% to above 400% of purchasing costs of 1 tonne of fresh high-silica sand. The contractual price accepted for such sand in the BREF UE document [3] is 14.56 Eu. Problems of scientific and development research concerning the reclamation of used foundry sands can be systematised according to the research fields and the actual state of knowledge - based on the analysis of scientific papers.

    Disc infiltration tests were carried out to study the soil infiltration characteristics under different rates of soil amendments application, and to investigate the effects of biochar and polyacrylamide (PAM) application on saline soil hydraulic properties, pore characteristics and contribution of each pore to soil water flow in coastal reclamation region. The results showed that soil satura-ted hydraulic conductivity increased by 46.4% when biochar was applied at 2% compared with the control, and decreased with increasing PAM application. The total effective soil porosity and r>100 μm pores were increased by 8.3% and 10.2% (PPAM application. Particularly, the total effective soil porosity decreased markedly when PAM was applied at 1‰ and the reduction was up to 88%. With the application of biochar and PAM, the contribution of r500 μm played a major role in determining water flows.

    The growing use of reclaimed wastewater for environmental purposes such as stream flow augmentation requires comprehensive ecological risk assessment and management. This study applied a system analysis approach, regarding a wastewater reclamation plant (WRP) and its recipient water body as a whole system, and assessed the ecological risk of the recipient water body caused by the WRP effluent. Instead of specific contaminants, two toxicity indicators, i.e. genotoxicity and estrogenicity, were selected to directly measure the biological effects of all bio-available contaminants in the reclaimed wastewater, as well as characterize the ecological risk of the recipient water. A series of physically based models were developed to simulate the toxicity indicators in a WRP through a typical reclamation process, including ultrafiltration, ozonation, and chlorination. After being validated against the field monitoring data from a full-scale WRP in Beijing, the models were applied to simulate the probability distribution of effluent toxicity of the WRP through Latin Hypercube Sampling to account for the variability of influent toxicity and operation conditions. The simulated effluent toxicity was then used to derive the predicted environmental concentration (PEC) in the recipient stream, considering the variations of the toxicity and flow of the upstream inflow as well. The ratio of the PEC of each toxicity indicator to its corresponding predicted no-effect concentration was finally used for the probabilistic ecological risk assessment. Regional sensitivity analysis was also performed with the developed models to identify the critical control variables and strategies for ecological risk management. Copyright © 2016 Elsevier Ltd.

    2007-01-01

    Presently, the BLM (Bureau of Land Management) has identified a multitude of abandoned mine sites in primarily Western states for cleanup. These sites are prioritized and appropriate cleanup has been called in to reclaim the sites. The task is great in needing considerable amounts of agency resources. For instance, in Colorado alone there exists an estimated 23,000 abandoned mines. The problem is not limited to Colorado or to the United States. Cooperation for reclamation is sought at local, state, and federal agency level to aid in identification, inventory, and cleanup efforts. Dangers posed by abandoned mines are recognized widely and will tend to increase with time because some of these areas are increasingly used for recreation and, in some cases, have been or are in the process of development. In some cases, mines are often vandalized once they are closed. The perpetrators leave them open, so others can then access the mines without realizing the danger posed. Abandoned mine workings often fill with water or oxygen-deficient air and dangerous gases following mining. If the workings are accidentally entered into, water or bad air can prove fatal to those underground. Moreover, mine residue drainage negatively impacts the local watershed ecology. Some of the major hazards that might be monitored by higher-resolution satellites include acid mine drainage, clogged streams, impoundments, slides, piles, embankments, hazardous equipment or facilities, surface burning, smoke from underground fires, and mine openings.

  6. Draft reclamation program plan for site characterization

    International Nuclear Information System (INIS)

    1989-08-01

    As part of its obligations under the Nuclear Waste Policy Act, as amended, the US Department of Energy (DOE) has developed an environmental program that is to be implemented during site characterization at the Yucca Mountain site. This site is proposed for the location of the nation's first high-level radioactive waste repository. A program for the reclamation of areas disturbed by site characterization is part of the overall environmental program for that site. This Reclamation Program Plan (RPP) describes the reclamation policy of the DOE for the Yucca Mountain site and presents an overview of the reclamation program. The RPP also provides an overview of the reclamation needs relative to site characterization; a review of legislation and requirements pertinent to reclamation; and a review of previous commitments made by the DOE to certain types of reclamation activities. The objective of the DOE reclamation program at Yucca Mountain is to return land disturbed by site-characterization activities to a stable ecological state with a form and productivity similar to the predisturbance state. The DOE will take all reasonable and necessary steps to achieve this objective. 19 refs., 2 tabs

    The evaluation of virus reduction in water reclamation processes is essential for proper assessment and management of the risk of infection by enteric viruses. Ultrafiltration (UF) with coagulation-sedimentation (CS) is potentially effective for efficient virus removal. However, its performance at removing indigenous viruses has not been evaluated. In this study, we evaluated the reduction of indigenous viruses by UF with and without CS in a pilot-scale water reclamation plant in Okinawa, Japan, by measuring the concentration of viruses using the real-time polymerase chain reaction (qPCR). Aichi virus (AiV) and pepper mild mottle virus (PMMoV) were targeted in addition to the main enteric viruses of concern for risk management, namely, norovirus (NoV) genogroups I and II (GI and GII) and rotavirus (RoV). PMMoV, which is a plant pathogenic virus and is present at high concentrations in water contaminated by human feces, has been suggested as a useful viral indicator. We also investigated the reduction of a spiked model virus (F-specific RNA bacteriophage MS2) to measure the effect of viral inactivation by both qPCR and plaque assay. Efficiencies of removal of NoV GI, NoV GII, RoV, and AiV by UF with and without CS were >0.5 to 3.7 log 10 , although concentrations were below the detection limit in permeate water. PMMoV was the most prevalent virus in both feed and permeate water following UF, but CS pretreatment could not significantly improve its removal efficiency (mean removal efficiency: UF, 3.1 log 10 ; CS + UF, 3.4 log 10 ; t test, P > 0.05). CS increased the mean removal efficiency of spiked MS2 by only 0.3 log 10 by qPCR (t-test, P > 0.05), but by 2.8 log 10 by plaque assay (t-test, P < 0.01). This difference indicates that the virus was inactivated during CS + UF. Our results suggest that PMMoV could be used as an indicator of removal efficiency in water reclamation processes, but cultural assay is essential to understanding viral fate.

  12. Feasibility of In-Situ Aeration of Old Dumping Ground for Land Reclamation

    Directory of Open Access Journals (Sweden)

    Huan-Huan Tong

    2013-12-01

    Full Text Available Dumping grounds are characterized by the absence of engineering controls such as base liners and cover layer. Consequently, these dumping grounds present risks for surrounding resources such as soil, groundwater and air. The concern for groundwater contamination by leachate from tropical dumping grounds is heightened due to the greater amounts of rainfall and subsequent infiltration and percolation through the waste mass. The emergent demand for old dumping grounds reclamation drives the need to employ remediation technologies. Generally, in-situ aeration is a remediation method that promotes aerobic conditions in the later stage of dumping ground. It accelerates carbon transfer, reduces remaining organic load, and generally shortens the post closure period. However, high rainfall in tropical areas straitens this technique. For example, pollutants could be easily flushed out and more energy should be required to overcome hydrostatic pressure. Although heavy rainfall could supply sufficient water to the substrate and accelerate degradation of organic matter, it may inhibit aerobic activities due to limited air transfer. The waste characterization from Lorong Halus Dumping Ground (closed dumping ground in Singapore showed that the waste materials were stabilized after 22 years closure. According to the Waste Acceptance Criteria set by European Communities Council, the waste materials could be classified as inert wastes. One interesting finding was that leachate layer detected was about of 5 - 8 meter depth, which entirely soaked the waste materials. Hence, the reclamation design and operation should be carefully adjusted according to these characters. Lorong Halus Dumping Ground case study can provide a guideline for other tropical closed landfills or dumping grounds.

  16. Paths toward reclamation: therapeutic jurisprudence and the regulation of medical practitioners.

    Science.gov (United States)

    Freckelton, Ian; Flynn, Joanna

    2004-08-01

    Much about what used to be termed "disciplinary" investigations and hearings is being revisited in the modern era. Therapeutic jurisprudence enables informed and sensitive awareness to potentially therapeutic and counter-therapeutic effects of both investigations and hearings conducted by medical regulatory authorities. This article analyses key aspects of authorities' processes from the perspective of notifiers/complainants and practitioners. Using developments at the Victorian Medical Practitioners Board as a base, it addresses issues of both investigative procedures and decision-making at formal and informal hearings, as well as the ramifications of re-hearings for the integrity of peer review informed regulation. It argues that where reclamation of practitioners is possible (namely where impropriety is not of the most serious order), there is much that is constructive about a focus upon enhancement of performance and competence levels, rather than the traditional preoccupation with whether registered status needs to be affected as a result of practitioner conduct.

  17. LANDSAT remote sensing: observations of an Appalachian mountaintop surface coal mining and reclamation operation

    International Nuclear Information System (INIS)

    1979-10-01

    The potential benefits of using LANDSAT remote sensing data by state agencies as an aide in monitoring surface coal mining operations are reviewed. A mountaintop surface mine in eastern Kentucky was surveyed over a 5 year period using satellite multispectral scanner data that were classified by computer analyses. The analyses were guided by aerial photography and by ground surveys of the surface mines procured in 1976. The application of the LANDSAT data indicates that: (1) computer classification of the various landcover categories provides information for monitoring the progress of surface mining and reclamation operations, (2) successive yearly changes in barren and revegetated areas can be qualitatively assessed for surface mines of 100 acres or more of disrupted area, (3) barren areas consisting of limestone and shale mixtures may be recognized, and revegetated areas in various stages of growth may be identified against the hilly forest background

    One of the important overriding themes of the Los Alamos National Laboratory as a world-class scientific institution is to utilize its expertise in enhancing the long-term welfare of society by minimizing negative side effects of nuclear technology over the past five decades. The Los Alamos National Laboratory is therefore committed to the use of its technical competencies and nuclear facilities, developed through programs in the areas of defense and civilian nuclear research, to support activities which will benefit the United States as a whole. As such, this paper discusses the organizational details and requirements of the Neutron Source Reclamation Program at Los Alamos. This program has as its mission the retrieval, interim storage, and chemical reprocessing of 238 PuBe, 239 PuBe and 24l AmBe neutron sources residing in the hands of private companies and industries, academic institutions, and various state and Federal government agencies

    To understand the status of schistosomiasis of staff in the Hydrology Bureau of Yangtze Water Resources Committee and the Oncomelania hupensis snail condition of their work areas in 2013, so as to provide the evidences for the schistosomiasis control in the industry. The physical examination data about schistosomiasis of the staff from 2006 to 2013 were collected and analyzed to understand the schistosomiasis prevalence condition of the staff and the changes of their liver parenchyma. Meanwhile, the snail status in the work areas was surveyed. There were 1,393 staff involved in the physical examinations of schistosomiasis in 2003, 197 of them were schistosomiasis patients, the prevalence rate was 14.14%, and no new acute schistosomiasis case occurred. The cases whose liver parenchyma were classified as Grade 0, I , II , III occupied 28.9%, 67.0%, 3.05% and 1.02%, respectively. A total of 24 work areas were involved in the snail survey, and 71 snails were captured. Among the whole snails captured, 39 were living snails, but no schistosome infected snails were found. The prevalence rate of schistosomiasis in staff of the Hydrology Bureau of Yangtze Water Resources Committee is relatively high, so the schistosomiasis surveillance as well as the snail survey and control still should be carried out consistently.

    Solar Evaporation Ponds (SEP) were used by Union Carbide India Limited (UCIL), Bhopal for storage of wastewater containing high concentrations of inorganic chemicals especially chlorides. Area occupied by the SEPs had to be recovered due to closure of the plant. A prerequisite to the reclamation of the SEP area is a study of adjoining soil and groundwater, which may be contaminated due to possible leakage in the pond. Surface soil, subsurface soil and groundwater samples were collected and analysed. The electrical conductivity method was employed inside the pond to test for leak in the geo-membrane liner. This was further confirmed by physically checking the liners. Based on the wet period, total rainfall and evaporation rate of the region, drying of remaining wastewater by spreading in dry ponds followed by pond dismantling was scheduled.

    1995-01-01

    An analysis of the difficulties associated with the re-establishment of reclamation vegetation on a dry underground coal mine site in southern Utah, USA, is presented. Precipitation amounts, seed mix, seed bed preparation techniques, and soil properties all appeared to be adequate for vegetation establishment at the site. However, failure of repeated revegetation efforts in a redisturbed area of the mine site may have been due to higher soil salinity levels in the area, which may have given 'Kochia scoparia' an initial competitive advantage. Lack of soil moisture and allelopathic effects due to the dense carpet of 'Kochi' may have also contributed to the continued lack of revegation success. 14 refs., 7 figs., 6 tabs

  2. Neutron activation, k0-- method, as a tool for Phytoremediation studies and reclamation of degraded areas

    Uemura, George; Menezes, Maria Angela de Barros C.

    2007-01-01

    Phytoremediation is a technology that can be considered as a relatively recent one, although it is based on knowledge that has been gathered and accumulated for a long time. One advantage of phytoremediation is its relatively low cost, but, as it must rely on plant growth, its results might be quite slow to be achieved, specially in countries with temperate climate, which is not the case of vast areas of Brazilian territory. One of the aims of phytoremediation is the search of plants that are hyperaccumulators, i.e., that are capable of accumulating pollutants and/or contaminants in high concentrations, of which the fern Pteris vittata is a fine example, considering arsenic accumulation. The possibilities of exploring Brazilian native flora for this purpose demand no further comments. The reclamation of degraded areas demands might not necessarily rely only on species and/or varieties that are hyperaccumulators, but also on taxa that are resistant to a given pollutant or a mixture of pollutants. In this case, a precise analysis of the environment is fundamental, specially to ascertain, for sure, that some toxic element is not present. In this work, species known to accumulate arsenic from Brazilian native flora like Indian mustard (Brassica juncea) and Mirabilis jalapa were grown and exposed to arsenic. After that, they were lyophilised and analysed by means of the k 0- standardization method using the TRIGA MARK I IPR-R1 reactor at CDTN/CNEN. Certified reference material were also analysed to verify the accuracy of the method. The advantages of neutron activation, k 0- method, a multi-elemental analysis technique, in phytoremediation and reclamation of degraded areas, are discussed in the present paper. (author)

    In this progress report of the Central Bureau for Nuclear Measurements at Geel (Belgium) researches related to neutron data and to non-neutron nuclear data are gathered. Neutron data are essentially related to cross-section measurements: for instance, concerning actinides, structural materials as Cr and Fe, fission products. Some studies are classified as concerning standard neutron data. Underlying physics is no forgotten neither than equipment (linear accelerator). Non-neutron nuclear data is concerned essentially with decay studies. Some compilations and evaluations are also given. Improvement of measurement and source preparation techniques is a part of this section

    A new concept of volume-retarded osmosis and low-pressure membrane (VRO-LPM) hybrid process was developed and evaluated for the first time in this study. Commercially available forward osmosis (FO) and ultrafiltration (UF) membranes were employed in a VRO-LPM hybrid process to overcome energy limitations of draw solution (DS) regeneration and production of permeate in the FO process. To evaluate its feasibility as a water reclamation process, and to optimize the operational conditions, cross-flow FO and dead-end mode UF processes were individually evaluated. For the FO process, a DS concentration of 0.15 g mL -1 of polysulfonate styrene (PSS) was determined to be optimal, having a high flux with a low reverse salt flux. The UF membrane with a molecular weight cut-off of 1 kDa was chosen for its high PSS rejection in the LPM process. As a single process, UF (LPM) exhibited a higher flux than FO, but this could be controlled by adjusting the effective membrane area of the FO and UF membranes in the VRO-LPM system. The VRO-LPM hybrid process only required a circulation pump for the FO process. This led to a decrease in the specific energy consumption of the VRO-LPM process for potable water production, that was similar to the single FO process. Therefore, the newly developed VRO-LPM hybrid process, with an appropriate DS selection, can be used as an energy efficient water production method, and can outperform conventional water reclamation processes.

  8. Bacterial Root Microbiome of Plants Growing in Oil Sands Reclamation Covers

    2017-05-01

    Full Text Available Oil sands mining in northern Alberta impacts a large footprint, but the industry is committed to reclaim all disturbed land to an ecologically healthy state in response to environmental regulations. However, these newly reconstructed landscapes may be limited by several factors that include low soil nutrient levels and reduced microbial activity. Rhizosphere microorganisms colonize plant roots providing hosts with nutrients, stimulating growth, suppressing disease and increasing tolerance to abiotic stress. High-throughput sequencing techniques can be used to provide a detailed characterization of microbial community structure. This study used 16S rRNA amplicon sequencing to characterize the bacterial root microbiome associated with annual barley (Hordeum vulgare and sweet clover (Melilotus albus growing in an oil sands reclamation area. Our results indicate that Proteobacteria dominated the endosphere, whereas other phyla such as Acidobacteria and Gemmatimonadetes were restricted to the rhizosphere, suggesting that plants have the ability to select for certain soil bacterial consortia. The bacterial community in the endosphere compartments were less rich and diverse compared to the rhizosphere. Furthermore, it was apparent that sweet clover plants were more selective, as the community exhibited a lower richness and diversity compared to barley. Members of the family Rhizobiaceae, such as Sinorhizobium and Rhizobium were mainly associated with clover, whereas Acholeplasma (wall-less bacteria transmitted by insects was unique to barley. Genera from the Enterobacteriaceae family, such as Yersinia and Lentzea were also mostly detected in barley, while other genera such Pseudomonas and Pantoea were able to successfully colonize both plants. Endophytic bacterial profiles varied within the same plant species at different sampling locations; however, these differences were driven by factors other than slope positions or cover management. Our results

    The declared mission of the International Bureau of Weights and Measures are the world uniformity of the measurement, however until some years ago a formal mechanism didn't exist for its complete implementation. With this end arose the Mutual Recognition Agreement whose specific objective is to establish the grade of equivalence of the national standards, the one of mutually recognizing the calibration and measurement certificates and the one of providing to the governments of a sure technical tool in its commercial negotiations and regulatory matters at international level. Cuba like an associated country to the Meter Convention, signed the agreement and it intended to demonstrate the international equivalence of its standards. The best measurement and calibration capacities of the country in the dosimetric magnitudes are in the Secondary Laboratory of Dosimetric Calibration of the Protection and Hygiene of Radiations Center. This capacities were included in the Regional Metrological Organization COOMET in the year 2003. In June of the 2005 the metrological capacities have been approved and published in the databases of the International Bureau of Weights and Measures as demonstration of the high competition of the calibration works that its are carried out in the laboratory. This approval is one of the maximum international recognitions that the patterns of a country can receive and its are the result of 10 years of work of the laboratory like part of the international net OIEA/OMS, which has given it the possibility to gauge the patterns and of adopting internationally validated calibration methodologies. On the other hand, it has been decisive the participation of the laboratory in multiple international comparisons of their patterns, as well as the implementation of a system of administration of the quality credited by the competent national organ. The article reviews the technical work of the laboratory during several years that it gave as result this

    A process to recover high purity 10 B enriched crystalline boron powder from a polymeric matrix was developed on a laboratory basis and ultimately scaled up to production capacity. The process is based on controlled pyrolysis of boron-filled scrap followed by an acid leach and dry sieving operation to return the powder to the required purity and particle size specifications. Typically, the recovery rate of the crystalline powder is in excess of 98.5 percent, and some of the remaining boron is recovered in the form of boric acid. The minimum purity requirement of the recovered product is 98.6 percent total boron

Processing organic materials or residues and the creation of high quality organic soil improving materials will close material cycles and contribute to the value added on a regional scale. This should be an essential part of a sustainable material flow management. The presentation will focus on the application of biochar substrates for the reclamation of sandy soils in Northeastern Germany. Lignite mining activities leave raw soils without humus on dumps and tips. The rapid formation and maintenance of a balanced humus and nutrient budget is of great importance. Field, lysimeter and pot experiments were part of the research program in order to find out the impact of biochar substrate application on soil functions and plant growth and to derive quality criteria and recommendations for practice. The results of the experiments show that application of biochar substrates (BCS) improved soil properties like nutrient supply, organic carbon content, water storage and cation exchange capacity. However, crop yields did not increase in the year of BCS application on the test sites or even decreased on the dumped soil with rising amounts of BCS. This is a consequence of nitrogen immobilization and sorption in the soils treated with BCS. Therefore, BCS applications should be combined with mineral fertilization of nitrogen and BCS production should be modified aiming to improve contents and release of plant available nitrogen. In the third year after BCS application variants treated with 60 t BCS ha-1 (15 Vol.-% biochar) showed highest yields, exceeding the variants with mineral fertilization. On the dumped soil, in the fourth and fifth year after

    The Bureau of Land Management (BLM) has been actively expanding its capacity to work cooperatively with other agencies, Tribes, the public, and other stakeholders using collaborative and alternative dispute resolution (ADR) approaches. In 1997, the BLM created the BLM’s Collaboration and Alternative Dispute Resolution Program (Collaboration/ADR Program) to centralize, strengthen, and coordinate these efforts. Specifically, the Collaboration/ADR Program is charged with developing ADR policies; ensuring that statutory and regulatory requirements are met; and providing training, resources, and direct support for collaboration and ADR in the BLM. At the request of the Collaboration/ADR Program, the Policy Analysis and Science Assistance Branch of the U.S. Geological Survey, located in the Fort Collins Science Center, conducted an online survey of BLM employees in early 2013 to address four overarching questions: What information sources and assistance resources are BLM employees currently accessing to fill their conflict/dispute resolution and collaboration needs?

    Anthropogenic activities create a number of significant greenhouse gases and thus potentially contribute to global warming. Methane production is significant in some agricultural production systems and from wetlands. In soil, methane can be oxidised by methanotrophic bacteria. However, little is known about methane production and oxidation in oil sand reclamation covers. The purpose of this study was to investigate methane production and oxidation potential of tailing sands and six different reclamation layers of oil sands mining sites in Alberta, Canada. Methane production and oxidation potential were investigated in laboratory scale microcosms through continuous headspace analysis using gas chromatography. Samples from a reclamation layer were collected at the Canadian Natural Resources Limited (CNRL) reclamation site at depths of 0-10 cm, 10-20 cm and 20-40 cm in October 2014. In addition, tailing sands provided by Suncor Energy Inc. and soil from a CNRL wetland were studied for methane production. Samples were dried, crushed and sieved to 4 mm, packed into serum bottle microcosms and monitored for eight weeks. Methane production potential was assessed by providing an anoxic environment and by adjusting the samples to a moisture holding capacity of 100 %. Methane oxidation potential was examined by an initial application of 2 vol % methane to the microcosms and by adjusting the samples to a moisture holding capacity of 50 %. Microcosm headspace gas was analysed for methane, carbon dioxide, nitrous oxide and oxygen. All experiments were carried out in triplicates, including controls. SF6 and Helium were used as internal standards to detect potential leaks. Our results show differences for methane production potential between the soil depths, tailing sands and wetlands. Moreover, there were differences in the methane oxidation potential of substrate from the three depths investigated and between the reclamation layers. In conclusion, the present study shows that

    Since the 1960s, the marshes in the Sanjiang Plain, Northeast China, which are an important reservoir for dissolved carbon, have undergone long-term reclamation to farmland, resulting in elevated marsh loss and degradation on a large scale. This study compared the concentrations of dissolved carbon, as well as the chemical characteristics of dissolved organic carbon (DOC), in natural marshes, a degraded marsh, and drainage ditches sampled during the growing seasons between 2008 and 2010 to clarify the temporal-spatial variability of the dissolved carbon in the fluvial system influenced by the long-term reclamation. The results show that the average concentrations of total dissolved carbon (TDC) and DOC are considerably greater in the natural marshes than in the degraded marsh and drainage ditches. The average DOC concentration for the natural marshes, approximately 35.53 ± 5.15 mg L(-1), is approximately 2.39 times that in the degraded marsh (14.84 ± 4.21 mg L(-1)) and 2.77 times the average value in the ditches (12.84 ± 4.49 mg L(-1)). The dissolved inorganic carbon (DIC) exhibits increased trends in the drainage ditches compared with the natural marshes, whereas the hydrophobic fraction of DOC is present at lower concentrations in the degraded marsh and ditches. Fluorescence indices also indicate that the DOC in the degraded marsh and ditches has a simpler humification structure. In total, the long-term reclamation has led to great variability in the DOC concentration and chemical characteristics in the fluvial system. Changes in the DOC production potential and hydrological regimes due to sustained reclamation are deemed the predominant causes of this effect. The continuously decreased DOC concentration and high variability of DOC in the surface fluvial systems are inevitable if reclamation continues in the Sanjiang Plain. More importantly, the presence of tyrosine and tryptophan-like substances in the ditches indicates that there has been extensive

    Coal mine sites can have significant effects on local environments. In addition to the physical disruption of land forms and ecosystems, mining can also leave behind a legacy of secondary detrimental effects due to leaching of acid and trace elements from discarded materials. This report looks at the remediation of both deep mine and opencast mine sites, covering reclamation methods, back-filling issues, drainage and restoration. Examples of national variations in the applicable legislation and in the definition of rehabilitation are compared. Ultimately, mine site rehabilitation should return sites to conditions where land forms, soils, hydrology, and flora and fauna are self-sustaining and compatible with surrounding land uses. Case studies are given to show what can be achieved and how some landscapes can actually be improved as a result of mining activity.

    Processes of possible self-restoration of technogenically disturbed soils are studied in Central and Southern European Russia. Reclamation procedures are mainly not implemented in this vast region, and the natural soil restoration is supposed. Heaps overlaying the former steppe and cropland landscapes are created in the course of rock waste stacking after preparative and cleaning mining works during the underground coal extraction. Approximately 1 500 heaps occupying over 8 000 ha were formed in the area of the Donets Coal Basin. Soils are destroyed under heaps, land subsidence occurs in coal mining areas and acid lakes are usually formed in these ground depressions. Spontaneous combustions happen often and can continue for decades. In order to prevent them, heap surfaces are in some cases levelled and filled with water, forming peculiar ponds. After 70 years of heaps existence and ca. 50 years after their ignition, soil formation is just in the early stages. Heap surface differs a lot in geochemical and mineralogical characteristics from those of surrounding steppe soils that suffered substantial changes at distances up to 1 km. Development of plant communities in areas near coal dumps and heaps is one of the indicators of landscape-geochemical changes. Formation of ruderal phytocenoses with 10-15 % of local flora, as well as invasive and introduced plants occurred under the complex impact of ecological conditions. Communities formed by them are distinguished by the structure simplicity, low species diversity, and plant growth anomalies. Quarries and dumps are formed during underground and open-cast mining of ore deposits. During the last 50 years after abandoning mines in forest areas, the 30 m deep quarries have filled with the creep material less for 0.5 m, and sediments from water streams have added 1-3 cm. Thickness of argillaceous layers does not exceed 1-2 cm at small rock chips of the dumps that measures up to 70 km in length. The dumps are partially

    Tynanthus panurensis (Bureau) Sanwith (Bignoniaceae) is a liana vine used in traditional Amazonian medicine as a tonic and energizer as well as a treatment for rheumatism. These traditional indications prompted this study of the antioxidant and anti-inflammatory activities of T. panurensis bark extract (ETP). Phytochemical analysis of ETP showed the presence of saponins and a high concentration of phenols and flavonoids. A battery of in vitro tests revealed that the extract has free radical-scavenging antioxidant properties and reduces microsomal lipid peroxidation, uric acid synthesis, and tumor necrosis factor-α production. The anti-inflammatory properties of ETP were further confirmed in vivo in a rat carrageenan edema model, in which the extract exhibited a potent activity. These results support the idea that T. panurensis bark extract could be beneficial for treating inflammation and are in agreement with one of the main traditional uses of this plant.

    A new mechanism modus of micro ultrasonic electroremoval (MUERM) using a precise nanostructure reclamation and a design twins-oval tool offering faster performance in removing the Indium-tin-oxide (In2O3SnO2) thin-films from the surface of the optical PET-diaphragm (PET) of digital paper is demonstrated. Through the ultra-precise etching of the nanostructure, the semiconductor industry can effectively reclaim defective products, thereby reducing production costs. For the removal-process, a faster feed rate of the PET combined with a higher electric current produces a faster removal rate. Using ultrasonic energy transmitted into the electrolyte to assist in the chemical reaction can improve the effect of dreg discharge and contributes to the achievement of a fast PET feed rate. The average removal effect of the ultrasonics is better than the pulsed current while the current rating needs not to be prolonged. The high rotational speed of the twins-oval tool increases the dreg discharge mobility and improves the removal effect. A small height of the anode and the cathode, or a large width of the cathode corresponds to a higher removal rate for the In2O3SnO2. A small arc edge radius of the anode and the cathode also corresponds to a higher removal rate for the In2O3SnO2.

    Plans are being made to construct Dalian Offshore Airport in Jinzhou Bay with a reclamation area of 21 km(2). The large-scale reclamation can be expected to have negative effects on the marine environment, and these effects vary depending on the reclamation techniques used. Water quality mathematical models were developed and biology resource investigations were conducted to compare effects of an underwater explosion sediment removal and rock dumping technique and a silt dredging and rock dumping technique on water pollution and fishery loss. The findings show that creation of the artificial island with the underwater explosion sediment removal technique would greatly impact the marine environment. However, the impact for the silt dredging technique would be less. The conclusions from this study provide an important foundation for the planning of Dalian Offshore Airport and can be used as a reference for similar coastal reclamation and marine environment protection.

    In this paper, an improved multi-scale integrated modeling framework has been established to evaluate coastal reclamation intensity (CRI). About 7 indicators are considered, including ecological degradation intensity (EDI), hydrodynamic disturbance (IHD), engineering types, water quality, economic investment, population growth, and reclaimed land area. Meanwhile, an integrated framework enhanced methods in terms of (a) measuring intensity of ecological degradation process under multi-scale impact, (b) developing the indicator system of CRI, and discussing the driving forces and trends of coastal reclamation, (c) determining fuzzy preference relations of weight and calculating the specific value of CRI with the case study areas of Yellow River estuary from 2000 to 2015. As the result, the CRI has been expanded unceasingly in recent years. The total growth rate from 2000 to 2015 is about 37.97%. It is concluded that CRI has climbed to a higher intensity level in resent 15years. Copyright © 2017. Published by Elsevier Ltd.

    A combined three-stage system, (1) coagulation (2) zeocarbon filtration and (3) membrane filtration, a combination of microfiltration (MF) and reverse osmosis (RO), was investigated for reclamation of tunnel construction wastewater having a salinity of 10.8-12.9‰ and a concentration of suspended solids (SS) in the range of 264-1084 mg/L. The initial stages - coagulation, zeocarbon filtration and MF - served as a precursor to RO membrane filtration to successfully reduce water contaminants to less than 0.2 nephelometric turbidity units (NTU) of turbidity, thereby minimizing the potential for fouling. The RO system subsequently removed over 99% of remaining pollutants including ionic substances, resulting in less than 0.02 NTU turbidity, less than 0.04 mg/L total nitrogen (TN) and less than 0.01 mg/L total phosphorus (TP). Also, addition of an RO system markedly reduced high salt concentrations (high chloride (Cl(-)) concentrations) in the wastewater, exceeding 99% salt elimination. Thus, reclaimed water from our combined system met and exceeded currently regulatory quality standards for wastewater reuse (turbidity ≤ 2.0 NTU; TN ≤ 10 mg/L; TP ≤ 0.5 mg/L; Cl(-) ≤ 250 mg/L).

  14. Challenges in forest reclamation of marginal lands: a balance between site conditions and seedling quality

    2017-04-01

    Forest loss and degradation is occurring worldwide, but at the same time efforts in forest restoration are ever increasing. While approaches to restoration often follow specific stakeholder objectives, regional climates and the degree of site degradation also play an important role in the prioritization of restoration efforts. Often the restoration of degraded lands can satisfy only few measurable objectives; however, to design and restore resistant and resilient ecosystems that can adapt to changing conditions, there is a need for new and adaptive management approaches. Mining and other resource extraction industries are affecting more and more forested areas worldwide. A priority in the reclamation and certification of forest lands disturbed by industrial activity is their expeditious redevelopment to functioning forests. To rehabilitate these heavily disturbed areas back to forest ecosystems, planting of trees remains one of the most effective strategies for the redevelopment of a continuous tree canopy on a site. It is well understood that access to good quality seedling stock is essential to achieve establishment success and early growth of seedlings. However, most reclamation areas have challenging initial site conditions and these conditions are often not a single factor but a combination of factors that can be additive or synergistic. Therefore successful forest restoration on degraded lands needs to consider multiple objectives and approaches to minimize trade-offs in achieving these objectives. To meet these demands, new methods for the production and evaluation of seedling stock types are needed to ensure that that seedlings are fit to grow on a wide range of site conditions or are particularly designed to grow in very specific conditions. Generally, defining seedling quality is difficult as it is species specific and results have been mixed; likely influenced by site conditions, further reiterating the need to carefully evaluate sites allowing

    Full Text Available A group of Minnesota architects created the ASHSB in 1914 to provide a solution for theshortage of middle class housing in the U.S. By 1919, the bureau had offices throughout the U.S. and received the endorsement of both the American Institute of Architects and the Department of Commerce. During this time, the members of the Bureau produced hundreds of plan sets and monthly bulletins to assist homeowners with their housing choices. The monthly magazine The Small Home, in conjunction with the published plan books--Your Future Home and How to Plan, Finance, and BuildYour Home--dispensed valuable information to potential homebuyers across the nation. To date, one master’s thesis (Lisa Schrenk, University of Virginia 1990 and an article (Thomas Harvey, 1991 have been written about the ASHSB. Neither one discussed the relationship of this group with the AIA, a keyendorsement agency.This research involved extensive archival research at the AIA. Records from the early 20th century were analyzed to determine the relationship between the AIA and the ASHSB in the early 20th century. This relationship provides insight into the current lack of architectural involvement in single-family house design today. The single most prevalent building type in the U.S. is the single-family house, yet architects are little involved in the design of most of them. Architects have the ability and training to create sustainable, affordable, and well-design single-family houses and yet they do not. This paper seeks to provide one explanation through the interpretation of the historic relationship of the AIA to the ASHSB.

    1979-12-01

    Eroding ridges of acidic coal-mine spoil in La Salle County, Illinois, were leveled to form a gently-sloped raised plateau. Four test plots were constructed: a control plot and three treatment plots that received a 0.9-m-thick cover of dredged material obtained from the Metropolitan Sanitary District of Greater Chicago. Two treatment plots received lime applications and all plots were seeded with a mixture of grasses. Pressure-vacuum soil water samplers were installed, in duplicate, at two levels in the control plot and at three levels in each treatment plot. The three levels in the treatment plots coincided with dredged material, the dredged-material mine-spoil interface, and the underlying mine spoil. Surface water, soil water, and groundwater were monitored for 29 water-quality parameters for one year. Rainfall, air temperature, runoff, and water-level elevation data were collected also. Detailed analysis of the data indicates that the dredged material used in this study does not adversely affect water quality; it supports abundant plant growth, lessens groundwater contamination, and controls acid runoff. The dredged material is judged to be a suitable material for use in reclamation of surface-mined land.

    2014-08-01

    Full Text Available The recent international competition for the reclamation of the Hiriya landfill (2004, located in the centre of Israel’s metropolitan area, was the climax of a fiveyear project, in which the fifty-year-old landfill (1948–1998, Israel’s largest, became the focus of international artistic, planning and design activities.This paper discusses the Hiriya project in order to explore the reciprocity between local activity within the field of landscape architecture and the global arena of landscape architecture practice, focusing specifically on the reclamation of marginal landscapes.For many years, Hiriya served as a symbol of Zionists’ environmental neglect. Therefore, unsurprisingly, the reclamation of the site and the design of the metropolitan park surrounding it became a national symbol of regeneration, involving world-renowned experts. By examining the planning process, and particularly the recent design competition, this paper explores the relationship between the local and the global, and significantly, the difficulty of bridging these opposing stands visà- vis landscape reclamation. The design process proved that, to be part of the global arena, it is not enough to bring in foreign designers and let them play according to local rules. It requires frankness toward greater  global cultural changes that are beyond the sole activity of design. The design proposals exemplify complex and rich interpretations of local and global ideas by both local and foreign designers, but ultimately proving that at times, outsiders are more successful in grasping the site’s genius loci than locals.

    The kidney maintains systemic acid-base balance by reclaiming from the renal tubule lumen virtually all HCO 3 - filtered in glomeruli and by secreting additional H + to titrate luminal buffers. For proximal tubules, which are responsible for about 80% of this activity, it is believed that HCO 3 - reclamation depends solely on H + secretion, mediated by the apical Na + /H + exchanger NHE 3 and the vacuolar proton pump. However, NHE3 and the proton pump cannot account for all HCO 3 - reclamation. Here, we investigated the potential contribution of two variants of the electroneutral Na + /HCO 3 - cotransporter NBCn2, the amino termini of which start with the amino acids MCDL (MCDL-NBCn2) and MEIK (MEIK-NBCn2). Western blot analysis and immunocytochemistry revealed that MEIK-NBCn2 predominantly localizes at the basolateral membrane of medullary thick ascending limbs in the rat kidney, whereas MCDL-NBCn2 localizes at the apical membrane of proximal tubules. Notably, NH 4 Cl-induced systemic metabolic acidosis or hypokalemic alkalosis downregulated the abundance of MCDL-NBCn2 and reciprocally upregulated NHE 3 Conversely, NaHCO 3 -induced metabolic alkalosis upregulated MCDL-NBCn2 and reciprocally downregulated NHE 3 We propose that the apical membrane of the proximal tubules has two distinct strategies for HCO 3 - reclamation: the conventional indirect pathway, in which NHE 3 and the proton pump secrete H + to titrate luminal HCO 3 - , and the novel direct pathway, in which NBCn2 removes HCO 3 - from the lumen. The reciprocal regulation of NBCn2 and NHE 3 under different physiologic conditions is consistent with our mathematical simulations, which suggest that HCO 3 - uptake and H + secretion have reciprocal efficiencies for HCO 3 - reclamation versus titration of luminal buffers.

    Large area of tidal flats in Chinese coast has been reclaimed to support agriculture and urban development because of rapid population and economic growth. Knowledge of soil development mechanisms is essential for efficient management of land resources in coastal zone. So far, most studies have focused on consequences of soil physico-chemical properties on soil quality evolution after tideland reclamation for cultivation; yet a large part of soil bioprocess drives many soil processes. The effect of organism composition on the performance of soil development remains unclear. The purpose of our work was to reveal the organism composition change and its influence on soil quality impotent. In this study, we choose seven reclamation districts along a chronosequence in eastern coast of China, which were respectively reclaimed in 1956, 1971, 1980, 1997, 2009, 2013 and unenclosed tidal flat. The latest districts reclaimed in 2013 were left to succession fallow which were covered with halophytic vegetation and the rest districts were agriculturally managed. Soil samples at 0-20 cm were collected in each district. Soil physical, chemical and biological properties and wheat yields were measured. The result showed after the transformation from tidal flat to cropland, longer tillage time (>5 year) lead to higher soil clay and silt, SOC contents and lower bulk density, while soil clay and C contents declined within the first 5 years after reclamation. Agricultural reclamation significantly improved SOC contents of 0-20 cm depth form 0.11±0.05% to 0.77±0.10%. It needs about 35 years to achieve stable yield level after reclamation. Meanwhile, the soil community composition changed strongly over time. More significant relationships were found among soil physicochemical properties and bacteria community. And the variation trend of soil community richness (chao1) is similar to soil C contents, dropped at first 5 years and then significantly increased. Our results indicate that the

    2017-11-01

    The structure of the mesoherpetobionts arthropod communities of the reclamated dump of the Krasnobrodsky coal pit (Kemerovo region, Russia) has been studied. It was established that the pioneer grouping of mesoherpetobionts arthropod represented by classes of Chilopoda, Arachnida and Insecta-Ectognatha has been formed on the dump for two years after the soil deposition. From the Arachnida, the species of the order Aranei are the most active in the stocking of the dumps. From the class Chilopoda, the species of Lithobiomorpha appear the first on the dump. Insects from the following three orders, Heteroptera, Hymenoptera and especially Coleoptera take the main part in the expansion of dumps and the formation of primary communities. Among the Coleoptera, the beetles of the family of Carabidae (44 species, dynamic density 22.9 specimens/10 trapped per day) dominate. From them, small or medium-sized species are mainly involved in stocking the dumps. There are significant differences in the complexes of ground dump carabid beetles in comparison with the control group, differing in species composition of dominant species, species richness and species diversity parameters

  12. Natural vs. plantation forests: A case study of land reclamation strategies for the humid tropics

    Jordan, Carl F.; Farnworth, Edward G.

    1982-11-01

    Biomass and productivity were compared in two plantations and in one stand of natural regeneration on similar sites in a premontane moist forest region of Puerto Rico. While initial growth rates of plantation species were higher, after four decades productivity of the natural regeneration plots was equal to or greater than productivity of the plantations. For the first 44 years, aboveground biomass of natural regeneration increased at an average annual rate of 3.8t·ha-1·yr-1, but the last year of the study it was 14.7t·ha-1. Biomass increment of a pine plantation averaged between 8 and 10.5t·ha-1·yr-1 except for one year when the rate was much lower, possibly because of hurricane damage. A tropical hardwood plantation averaged close to 4t·ha-1·yr-1 for 41 years. It is suggested that in countries where funds for land reclamation are limited, intensive plantations may not always be the best strategy. Natural regeneration or shelterbelt plantations may be suitable alternatives.

    Water reclamation plants frequently utilise reverse osmosis (RO), generating a concentrated reject stream as a by-product. The concentrate stream contains salts, and dissolved organic compounds, which are recalcitrant to biological treatment, and may have an environmental impact due to colour and embedded nitrogen. In this study, we characterise organic compounds in RO concentrates (ROC) and treated ROC (by coagulation, adsorption, and advanced oxidation) from two full-scale plants, assessing the diversity and treatability of colour and organic compounds containing nitrogen. One of the plants was from a coastal catchment, while the other was inland. Stirred cell membrane fractionation was applied to fractionate the treated ROC, and untreated ROC along with chemical analysis (DOC, DON, COD), colour, and fluorescence excitation-emission matrix (EEM) scans to characterise changes within each fraction. In both streams, the largest fraction contained 10 kDa molecules, with 17-34% of organic compounds as COD. Iron coagulation affected a wider size range, with better removal of organics (41-49% as COD) at the same molar dosage. As with iron, adsorption reduced organics of a broader size range, including organic nitrogen (26-47%). Advanced oxidation (UV/H2O2) was superior for complete decolourisation and provided superior organics removal (50-55% as COD). Copyright © 2011 Elsevier Ltd. All rights reserved.

    2007-01-01

    The filtration characteristics of two different module configurations with coarse pore filter (non-woven fabric) were investigated for sludge floc separation in an activated sludge reactor for domestic wastewater reclamation. A polypropylene non-woven fabric filter (35 g/m2) was used for the two different module configurations, one flat and one tubular type, each with a filtration area of 0.052 m2. The different module types, submerged in the oxic compartment of A/O (anaerobic/oxic) type reactors, were operated simultaneously. The filtration fluxes were gradually increased from 0.5 to 1.2 and 1.73 m/d. The filtration pressures were more stably maintained for the tubular type module than the plate type. The tubular type module installed horizontally with two-side suction showed less filtration pressures than the tubular type module installed vertically with one-side suction. The solid separation was significantly high showing less than 5 mg/L effluent solids. The organic and T-N removal efficiencies were around 95 and 50%, respectively. The 85% removal of T-P was achieved with 20 mg/L injection of PAC (poly-aluminum chloride).

    2017-01-01

    Full Text Available Tin mining in Bangka Belitung has been exploited for hundred years. The province is the second largest tin producer in the world. Secondary data from studies which took place in all four regencies in Bangka Island were discussed to show the impact of mining activities and its reclamation studies. In order to add plant selection criteria for regevetate mined soil, the greenhouse and laboratory experiment was carried out with fourteen herbs and grass species in Tennessee. The mining activities increase the wealth of the community, but the other hand they change and decrease the environmental stability, and cause horizontal conflicts. Offshore mining reduced water quality, change sea bed caused the change of biodiversity. Onshore mining activity reduces biodiversity and causes floods and damages infrastructure. While the more economic species are demanded, planting local tree species is challenging. An evaluation with local tree species concluded that best adapted species based on anatomical and physiological measurements was not those that showed the best performance in the field. The greenhouse and laboratory findings indicate that some physiological characteristics i.e. plant height and cover, transpiration rate, and foliar pigments may be used to select plant adaptability to mined soil.

    The total reclamation of any site requires time, physical control of the site, favorable natural conditions, and a considerable capital investment. It must be realized that processes involving biological systems require time to become established and self-sustaining. The Staunton 1 project has been designed to provide data on many aspects of the reclamation process. Data collected to date indicate a significant improvement in overall environmental quality, a substantial increase in the economic potential of the site and adjacent properties, and a genuine enhancement of the entire area's aesthetic value. The Staunton 1 Reclamation Demonstration Project, in addition to reclaiming this one site, will provide the necessary design data for future reclamation efforts of this type.

    The historical development of a process of reclamation of intertidal areas in an estuary has been quantitatively studied by means of old engravings, maps, navagation charts, and aerial photographs. These show that about 83 percent of the natural coastline of the estuary has disappeared, nearly two-thirds of its intertidal area has been covered, and over 40 percent of its volume has been lost. The rate of this artificial process is several tens of times faster than that of the natural sedimentation. Extrapolation of the observed trends shows that, if these continue, the intertidal areas would disappear completely in 31 to 105 years. Theoretical calculations based on comparisons with other estuaries show that the accumulated loss in the productivity of living matter (in the form of primary producers), since the process started about 140 years ago, could reach 1.5·1010 kg. This could represent, considering several possible food chains, the equivalent of the food necessary to sustain several thousand people for life. An economic analysis of the impact of the process has been made by considering, first, the decrease in fish and shellfish catches in the bay (using historical data and data about present clam productivity) and the decrease in its aesthetic quality and recreational potential. These were determined by means of interviews with the population to obtain a “demand curve” for the willingness to pay for the preservation and use of the bay. Second, the price of the man-made land obtained was considered. The data obtained show that the economic losses would offset the benefits within 10 to 30 years.

    Hoyer, Jesse L.

    1993-01-01

    Turbomilling, an innovative grinding technology developed by the U.S. Bureau of Mines in the early 1960's for delaminating filler-grade kaolinitic clays, has been expanded into the areas of particle size reduction, material mixing, and process reaction kinetics. The turbomill, originally called an attrition grinder, has been used for particle size reduction of many minerals, including natural and synthetic mica, pyrophyllite, talc, and marble. In recent years, an all-polymer version of the turbomill has been used to produce ultrafine, high-purity, advanced ceramic powders such as SiC, Si3N4, TiB2, and ZrO2. In addition to particle size reduction, the turbomill has been used to produce intimate mixtures of high surface area powders and whiskers. Raw materials, TiN, AlN, and Al2O3, used to produce a titanium nitride/aluminum oxynitride (TiN/AlON) composite, were mixed in the turbomill, resulting in strength increases over samples prepared by dry ball milling. Using the turbomill as a leach vessel, it was found that 90.4 pct of the copper was extracted from the chalcopyrite during a 4-hour leach test in ferric sulfate versus conventional processing which involves either roasting of the ore for Cu recovery or leaching of the ore for several days.

  5. THE DEVELOPMENT OF SYNTHETIC SOIL MATERIALS FOR THE SUCCESSFUL RECLAMATION OF ABANDONED MINED LAND SITES

    2006-03-01

    Abandoned mine sites associated with coal and metal mining across the western United States have been left as unproductive wastelands. The availability of soil materials or other materials to support the restoration of the vegetative cover and enhance the recovery of such areas is limited. The restoration of these areas often requires the use of available amendments such as organic waste products or to help stabilize the soil. Many of the organic waste products, including sewage sludge, clarifier sludge, fly ash sludge, and other by-products from the agricultural industries such as compost can be employed for beneficial uses. This study looked at the feasibility of applying organic waste products to a mine soil in Montana to increase soil fertility and enhance plant productivity. Waste rock samples were tested for acid forming potential via acid base accounting. Samples cores were constructed and leached with simulated rainwater to determine amendment affect on metal leaching. A greenhouse study was completed to determine the most suitable amendment(s) for the field mine land site. Results from the acid base accounting indicate that acid formed from the waste rock would be neutralized with the alkalinity in the system. Results also show that metals in solution are easily held by organics from the amendments and not allowed to leach in to the surrounding water system. Data from the greenhouse study indicated that the amendment of sewage sludge was most promising. Application of 2% sewage sludge along with 1% sewage sludge plus 1% clarifier sludge, 2% compost, and no treatment were used for mine land application. Initial results were encouraging and it appears that sewage sludge may be a good reclamation option for mine lands.

    The purpose and major goal of the Bureau of Products and Standards (BPS) is to support IAG's Global Geodetic Observing System (GGOS) in its objective to obtain consistent products describing the geometry, rotation and gravity field of the Earth, along with its variations in time. The work of the BPS is primarily built on the IAG Services and the products they derive on an operational basis from various geodetic observation techniques such as VLBI, SLR/LLR, GNSS, DORIS, satellite altimetry, gravity satellite missions, gravimetry, etc. In this framework it is a fundamental requirement that common standards and conventions are used by all IAG components for the analysis of the different geodetic observations. The BPS also concentrates on the integration of geometric and gravimetric parameters and the development of new products, required to address important geophysical questions and societal needs. In this presentation we give an overview about the key activities of the BPS and summarize the major findings of its recent activities. Some examples of the BPS inventory on standards and conventions used for the generation of IAG products, which has recently been published in the IAG Geodesist's Handbook 2016, will be highlighted, indicating that there are several shortcomings and deficiencies. It will also be discussed how to proceed with the recommendations given in the inventory and how to resolve inconsistencies and gaps. Finally, this presentation will give an overview about the future plans of the BPS towards the development of new products based on the integration of geometric and gravimetric observations.

  12. Internet access and sexual offences against children: an analysis of crime bureau statistics from India

    Directory of Open Access Journals (Sweden)

    Subahani Shaik

    2015-07-01

    Full Text Available Introduction: The association between pornography and sexual crime is controversial, with various researchers finding positive, no, or negative associations. Recent evidence suggests that there may be a specific association between child pornography, which is easily available on the Internet, and sexual offences against children. Methods: Using methodology similar to an earlier study from India, we obtained official statistics on sexual offences against children, namely rape and procurement of minor girls, for the period 2000-2012 from the National Crime Records Bureau. We analysed the association between the rates of these crimes and Internet access, measured by the number of users per 1,00,000 people. Results: Even after correcting for population growth, we found significant linear associations between Internet availability and the rates of both these offences against children. However, there was no correlation between the growth rate of Internet access and the rate of increase of these crimes. Discussion: While the association between pornography and the rape of adults is still under debate, our results provide indirect evidence of a possible association between Internet availability and sexual crimes against children. Regulation of the Internet to suppress access to child pornography may prevent at least some of these crimes.

    The purpose of this analysis is to provide the U.S. Department of the Interior (DOI) and the Bureau of Land Management (BLM) with an overview of renewable energy (RE) generation markets, transmission planning efforts, and the ongoing role of the BLM RE projects in the electricity markets of the 11 states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming) that comprise the Western Electricity Coordinating Council (WECC) Region. This analysis focuses on the status of, and projections for, likely development of non-hydroelectric renewable electricity from solar (including photovoltaic [PV] and concentrating solar power [CSP]), wind, biomass and geothermal resources in these states. Absent new policy drivers and without the extension of the DOE loan guarantee program and Treasury's 1603 program, state RPS requirements are likely to remain a primary driver for new RE deployment in the western United States. Assuming no additional policy incentives are implemented, projected RE demand for the WECC states by 2020 is 134,000 GWh. Installed capacity to meet that demand will need to be within the range of 28,000-46,000 MW.

    The GGOS Bureau of Products and Standards (BPS) supports the IAG in its goal to obtain products of highest possible accuracy, consistency, and temporal and spatial resolution, which should refer to a consistent reference frame, stable over decades in time. To achieve this important goal, it is a fundamental requirement that common standards and conventions are used by all IAG components for the analysis of the different space geodetic observations. The BPS also concentrates on the integration of geometric and gravimetric parameters and the development of new products, required to address important geophysical questions and societal needs. In this presentation we summarize the major findings of the product-based inventory, which has been compiled by the BPS, addressing the following major products and topics, such as the terrestrial and celestial reference frames, the Earth orientation parameters, GNSS satellite orbits, gravity field models and vertical reference frames. Some examples of this inventory will be highlighted, indicating that there are several shortcomings and deficiencies. It will also be discussed how to proceed with the recommendations given in the inventory and how to resolve inconsistencies and gaps. Finally, we will give an overview about the future plans of the BPS towards the development of new products based on the integration of geometric and gravimetric observations.

    The estimated amount of water resources is about 63 billion cubic meters in Korea. However, due to the lack of precipitation during the dry season, natural flows are not enough for the water supply. In addition, since the lack of water affects water quality, environmental problems are occurred in natural and social systems. In this study, we investigated the application feasibility of ferrate(VI) systems to water and wastewater treatment. And we'd like to suggest an alternative solution for conservation and efficient reuse of the limited water resources. In the research area of environmental applications, a primary interest has been focused to the power of ferrate(VI) systems in the decomposition of pollutants in wastewater and industrial effluents due to its potential use as a strong, relatively non-toxic, and oxidizing agent for diverse environmental contaminants. Also ferrate(VI) has additional advantages as a very efficient coagulant and a sorbent of pollutants. We have analysed and compared several ferrate(VI) manufacturing processes, especially focused on the electro chemical methods(Fig. 1). And we have investigated the applications of the manufactured ferrate(VI) in our own laboratory and the commercial ferrate(VI) to decomposition of persistent organic pollutants in water. Under optimal conditions, the removal efficiencies of 2-chlorophenol and benzothiophene were above 90%(Fig. 2). The ferrate system(VI) is promising and can be one of the most efficient alternatives among the advanced oxidation processes(AOPs) for degradation of persistent organic pollutants, and is an innovative technology for the wastewater reclamation, water reusing systems, and water treatment systems.

    Inappropriate usage of reclaimed wastewater has caused outbreaks of viral infectious diseases worldwide. International and domestic guidelines for wastewater reuse stipulate that virus infection risks are to be regulated by the multiple-barrier system, in which a wastewater treatment process composed of sequential treatment units is designed based on the pre-determined virus removal efficiency of each unit. The objectives of this review were to calculate representative values of virus removal efficiency in wastewater treatment units based on published datasets, and to identify research topics that should be further addressed for improving implementation of the multiple-barrier system. The removal efficiencies of human noroviruses, rotaviruses and enteroviruses in membrane bioreactor (MBR) and conventional activated sludge (CAS) processes were obtained by a systematic review protocol and a meta-analysis approach. The log10 reduction (LR) of norovirus GII and enterovirus in MBR were 3.35 (95% confidence interval: 2.39, 4.30) and 2.71 (1.52, 3.89), respectively. The LR values of rotavirus, norovirus GI and GII in CAS processes were 0.87 (0.20, 1.53), 1.48 (0.96, 2.00) and 1.35 (0.52, 2.18), respectively. The systematic review process eliminated a substantial number of articles about virus removal in wastewater treatment because of the lack of information required for the meta-analysis. It is recommended that future publications should explicitly describe their treatment of left-censored datasets. Indicators, surrogates and methodologies appropriate for validating virus removal performance during daily operation of wastewater reclamation systems also need to be identified.

    Previous studies reported (15)N enrichment of biota in reclamation wetlands that contain oil sands processed material (e.g., processed water and tailings); however, there is little information on the factors controlling (15)N enrichment in these systems. In this microcosm study, the aim was to examine stable C and N isotopes and growth (chlorophyll a [chl a] and dry weight) of algae as a function of exposure to different sources and concentrations of water-soluble fractions (WSF) derived from tailings. Two sources of tailings including mature fine tailings (MFT) and consolidated tailings (CT) and peat-mineral overburden were utilized to generate separate WSF that differed in water quality. In general, there was (15)N enrichment of filamentous algae along the increasing gradient of WSF/nutrient concentrations in both CT and peat microcosms, and among the different sources, algae were more (15)N enriched in CT WSF than in peat WSF. Growth of filamentous algae was inhibited at higher WSF concentrations, possibly due to reduced light availability at elevated levels of fine clay particles in MFT microcosms and colored dissolved organic carbon (DOC) in peat microcosms. Filamentous algae displayed lower biomass and (15)N depletion in 100% peat WSF. This study indicated that both the quality (source) and quantity of WSF affected algal growth and directly and/or indirectly influenced δ(15)N of algae. The distinct (15)N enrichment of primary producers derived from tailings suggest that stable N isotopes might be useful to trace exposure to oil sands processed material in biota that utilize these resources in reclaimed systems constructed with tailings or natural systems that receive tailings dyke seepage.

    Public land management agencies, such as the Bureau of Land Management (BLM), are charged with managing rangelands throughout the western United States for multiple uses, such as livestock grazing and conservation of sensitive species and their habitats. Monitoring of condition and trends of these rangelands, particularly with respect to effects of livestock grazing, provides critical information for effective management of these multiuse landscapes. We therefore investigated the availability of livestock grazing-related quantitative monitoring data and qualitative region-specific Land Health Standards (LHS) data across BLM grazing allotments in the western United States. We then queried university and federal rangeland science experts about how best to prioritize rangeland monitoring activities. We found that the most commonly available monitoring data were permittee-reported livestock numbers and season-of-use data (71% of allotments) followed by repeat photo points (58%), estimates of forage utilization (52%), and, finally, quantitative vegetation measurements (37%). Of the 57% of allotments in which LHS had been evaluated as of 2007, the BLM indicated 15% had failed to meet LHS due to livestock grazing. A full complement of all types of monitoring data, however, existed for only 27% of those 15%. Our data inspections, as well as conversations with rangeland experts, indicated a need for greater emphasis on collection of grazing-related monitoring data, particularly ground cover. Prioritization of where monitoring activities should be focused, along with creation of regional monitoring teams, may help improve monitoring. Overall, increased emphasis on monitoring of BLM rangelands will require commitment at multiple institutional levels.

    The coal mining history in Canmore, Alberta was presented along with reclamation activities that mine regulators carried out following closure of the mines after nearly 100 years of underground mining. The 7 seams that were mined commercially extend over distances of a few hundred feet and have been displaced by faults. Voids and collapsed rubble in shallow underground workings pose a risk of potential ground subsidence that can affect the stability of surface structures and infrastructure, including the planned development of the proposed Three Sisters Mountain Village on land above the abandoned mines. The village includes plans for 10,000 residential homes, 2 golf courses, and a resource centre. A mine works mitigation program involved drilling primary injection boreholes on a 15 m grid pattern to map the constraint zones in order to gain a better perspective of the subsidence issues as well as the effects of subsidence on structural stress and public safety. When determining mitigation criteria, various land uses and ranges of subsidence hazards were considered to be compatible with each land use. A paste backfill composed of aggregate from a locally available till overburden site was mixed with cement and injected into the void spaces. This paper described the cemented paste backfill injection method; confirmatory methods; maximum volume and pressure criteria; survey for ground uplift; and borehole camera and manual checks for cemented paste backfill in adjacent boreholes. Quality control testing was carried out by means of slump tests. It was concluded that cemented paste backfill mix could be used successfully to stabilize abandoned mine workings for land recovery. 8 refs., 5 tabs., 7 figs.

    Full Text Available Infections by protozoans of the genus Leishmania are the major worldwide health problem, with high endemicity in developing countries. The drugs of choice for the treatment of leishmaniasis are the pentavalent antimonials, which exert renal and cardiac toxicity. Thus, there is a strong need for safer and more effective treatments against leishmaniasis. The present study was designated to evaluate, by a bioguided assay, the leishmanicidal activity of hidro-ethanolic extracts from different parts (leves, caule and root of one same plant the Arrabidaea brachypoda (DC. Bureau. Its has been used to relieve general pain, painful joints and kidney stones in Brazilian folk medicine. Nevertheless, scientific information regarding this species is scarce; there are no reports related to its possible leishmanicidal activity. The leves extract presented the best activity on promastigotes forms of Leishmania (L. amazonensis, when compared to the other extracts. It showed significant activity on Leishmania (L. amazonensis. Our results are promising, showing that these compounds are biologically active on Leishmania (L. amazonensis.

    Full Text Available Abstract Background A retrospective examination was conducted of injuries, physical fitness, and their association among Federal Bureau of Investigation (FBI new agent trainees. Methods Injuries and activities associated with injuries were obtained from a review of medical records in the medical clinic that served the new agents. A physical fitness test (PFT was administered at Weeks 1, 7 and 14 of the 17-week new agent training course. The PFT consisted of push-ups, sit-ups, pull-ups, a 300-meter sprint, and a 1.5-mile run. Injury data were available from 2000 to 2008 and fitness data were available from 2004 to early 2009. Results During the survey period, 37% of men and 44% of women experienced one or more injuries during the new agent training course (risk ratio (women/men = 1.18, 95% confidence interval = 1.07-1.31. The most common injury diagnoses were musculoskeletal pain (not otherwise specified (27%, strains (11%, sprains (10%, contusions (9%, and abrasions/lacerations (9%. Activities associated with injury included defensive tactics training (48%, physical fitness training (26%, physical fitness testing (6%, and firearms training (6%. Over a 6-year period, there was little difference in performance of push-ups, sit-ups, pull-ups, or the 300-meter sprint; 1.5-mile run performance was higher in recent years. Among both men and women, higher injury incidence was associated with lower performance on any of the physical fitness measures. Conclusion This investigation documented injury diagnoses, activities associated with injury, and changes in physical fitness, and demonstrated that higher levels of physical fitness were associated with lower injury risk.

  13. Organizational behavior of regulatory agencies: a case study of the Bureau of Consumer Services in the Pennsylvania Public Utility Commission

    Silver, J.H.

    1981-01-01

    Regulatory agencies operate in a complex field of organizations and interest groups. The variety of behaviors that occur in the regulatory field are not satisfactorily explained by current interpretative frameworks. Regulatory agencies are at once criticized and praised. They flourish as organizational entities, yet they exhibit behavior that is often inexplicable. Notions like clientele capture, the politics of regulation, exchange theory, and institutionalized organizations do not singly explain the vagaries of regulatory behavior. A merger of these viewpoints, however, provides a foundation for a comprehensive interpretative framework. A bureau of consumer services within a state public utility commission is viewed as an institutionalized organization. From this perspective, a variety of ritual behaviors, based upon symbolic and tangible interorganizational exchanges are observed and characterized. The outcome of these exchanges is the establishment of the Bureau of Consumer Services as a legitimate regulatory agent with significant impact upon the formulation of regulatory policy in the formal proceedings of the Pennsylvania Public Utility Commission.

    The Staunton 1 Reclamation Demonstration Project involves an evaluation of the reclamation process for a deep coal mine refuse system. A typical abandoned midwestern deep coal mine refuse site was selected, final land use was determined, baseline data were collected, engineering plans were developed and implemented, and a post-construction evaluation was begun. The project is a cooperative effort by two state agencies--the Abandoned Mined Land Reclamation Council of Illinois the Illinois Institute for Environmental Quality--and the U.S. Department of Energy through the Land Reclamation Program at Argonne National Laboratory. Current investigations are monitoring groundwater, surface water quality, aquatic ecosystems, revegetation, soil characteristics, erosion and runoff, soil microbial and soil fauna populations, wildlife, and economic effects of the reclamation effort. The research is a multidisciplinary approach to the concept of ecosystem response to reclamation.

    2017-01-01

    Abandoned tailings ponds produce environmental and human health hazards due to the transfer of heavy metals through wind and water erosion or leaching. To reduce these hazards, a reclamation strategy has been developed on a tailings pond based on aided phytostabilization. In 2011 marble mud and pig slurry were applied to the surface of a tailings pond and in the spring of 2012 thirteen native vegetal species were introduced. The evolution of different soil properties and the bio-available fraction of the heavy metals Cd, Pb and Zn were monitored for two years (2012-2013). The results showed that the pH, aggregate stability, organic carbon, total nitrogen and cation exchange capacity increased after the application of the amendments and the growth of vegetation, whilst the bio-available fraction of the heavy metals drastically decreased (90-99%). Thus, the strategy followed proved to be positive for reducing the availability of heavy metals and improving soil quality and fertility. These results are promising in areas with extractive activity of carbonated materials, since the generated waste can be used for the reclamation of soils affected by heavy metals, transforming a residual material into a useful by-product.

    Canola seed lots of four varieties (Serow4, Serow6, Pactol as local cultivars and Evita as exotic variety) were treated with gamma rays at four doses (0, 100, 400 and 600 Gy). The present study aims to evaluate useful mutations in canola which possess high seed yield and oil content under new reclamation desert land at Ras-Suder-Sinai (saline) and Inshas (harsh and poor fertility) in M 4 and M 5 generations. The results at M 4 and M 5 generations showed that the 13-selected mutant lines on the bases of number of pods and seed yield/plant differed in their yield response according to environmental conditions. Over the two locations, the highest number of pods plant and seed yield was found at line 75 (M4) and line 11 for seed yield and line 78 for number of pods in M5 compared to other genotypes. More over, all the mutant lines compared to their parents showed significant or insignificant increases for all studies traits during the two successive generations. Over the two generations, the highest mean value compared to all genotypes was found in line 22 for plant height at Sudr and line 11 at Inshas, for fruiting zone length, the highest value was noticed in line 18 at Sudr and line 75 at Inshas, for the highest number of pods, (125/plant) it was found in line 63 at Sudr and (193/plant) in line 75 at Inshas which reflected the highest seed yield ( 8 g/plant).The highest mean value compared to all genotypes was found for 100 seed-weight in line 8 at Sudr and line 11 at Inshas which appeared the highest seed yield at Suder. Over all studied conditions, the mutant line 75 derived from Evita variety was characterized by the highest mean values for fruiting zone length of plant and number of pods/plant, reflecting a high seed yield (6.47 g/plant ) or about 83.87% over its parent. The increase of seed yield/plant for mutant line 11 over its parent was about 68.8% followed by line 8 surpassed its parent for seed yield by about 60.2 %. The oil content of canola seeds in

    2011-12-01

    Full Text Available Abstract Background A one-year prospective examination of injury rates and injury risk factors was conducted in Federal Bureau of Investigation (FBI new agent training. Methods Injury incidents were obtained from medical records and injury compensation forms. Potential injury risk factors were acquired from a lifestyle questionnaire and existing data at the FBI Academy. Results A total of 426 men and 105 women participated in the project. Thirty-five percent of men and 42% of women experienced one or more injuries during training. The injury incidence rate was 2.5 and 3.2 injuries/1,000 person-days for men and women, respectively (risk ratio (women/men = 1.3, 95% confidence interval = 0.9-1.7. The activities most commonly associated with injuries (% of total were defensive tactics training (58%, physical fitness training (20%, physical fitness testing (5%, and firearms training (3%. Among the men, higher injury risk was associated with older age, slower 300-meter sprint time, slower 1.5-mile run time, lower total points on the physical fitness test (PFT, lower self-rated physical activity, lower frequency of aerobic exercise, a prior upper or lower limb injury, and prior foot or knee pain that limited activity. Among the women higher injury risk was associated with slower 300-meter sprint time, slower 1.5-mile run time, lower total points on the PFT, and prior back pain that limited activity. Conclusion The results of this investigation supported those of a previous retrospective investigation emphasizing that lower fitness and self-reported pain limiting activity were associated with higher injury risk among FBI new agents.

  19. Estimated abundance of wild burros surveyed on Bureau of Land Management Lands in 2014

    2015-01-01

    The Bureau of Land Management (BLM) requires accurate estimates of the numbers of wild horses (Equus ferus caballus) and burros (Equus asinus) living on the lands it manages. For over ten years, BLM in Arizona has used the simultaneous double-observer method of recording wild burros during aerial surveys and has reported population estimates for those surveys that come from two formulations of a Lincoln-Petersen type of analysis (Graham and Bell, 1989). In this report, I provide those same two types of burro population analysis for 2014 aerial survey data from six herd management areas (HMAs) in Arizona, California, Nevada, and Utah. I also provide burro population estimates based on a different form of simultaneous double-observer analysis, now in widespread use for wild horse surveys that takes into account the potential effects on detection probability of sighting covariates including group size, distance, vegetative cover, and other factors (Huggins, 1989, 1991). The true number of burros present in the six areas surveyed was not known, so population estimates made with these three types of analyses cannot be directly tested for accuracy in this report. I discuss theoretical reasons why the Huggins (1989, 1991) type of analysis should provide less biased estimates of population size than the Lincoln-Petersen analyses and why estimates from all forms of double-observer analyses are likely to be lower than the true number of animals present in the surveyed areas. I note reasons why I suggest using burro observations made at all available distances in analyses, not only those within 200 meters of the flight path. For all analytical methods, small sample sizes of observed groups can be problematic, but that sample size can be increased over time for Huggins (1989, 1991) analyses by pooling observations. I note ways by which burro population estimates could be tested for accuracy when there are radio-collared animals in the population or when there are simultaneous

    Full Text Available The Rieti Plain is crowned by calcareous-marly reliefs (Rieti and Sabini Mountains and represents an intra-Apennine Plio- Quaternary alluvial and fluvial-lacustrine basin formed after multistage extensional tectonic processes. This territory presents huge amounts of water resources (Velino and Turano rivers; several springs; Lungo and Ripasottile lakes, relics of ancient Lacus Velinus. The aquifers occurring in the reliefs often have hydraulic continuity with the Rieti plain groundwater (detected at about 1-4 m below ground surface, which has general flow directions converging from the reliefs to the lake sector. Hydraulic exchanges between groundwater and surface waters are variable in space and time and play a relevant role for groundwater resource distribution. The Rieti Land Reclamation Authority was instituted in 1929 by Royal Decree N. 34171-3835, and integrates eight former authorities, dating the end of 1800s. It contributes to maintain the reclamation actions in the Rieti Plain, which started with the realization of the Salto and Turano artificial reservoirs, along two left tributaries of Velino River. The hydroelectric energy production purposes struggle with the reclamation and flood mitigation activities in the plain. The Land Reclamation Authority actuated the Integrated Reclamation General Project through the realization of pumping stations, connection and drainage canals, forestry-hydraulic works, rural roads, movable dams along Velino River and irrigation ditches. The irrigation activities, granted by the derivation of 5 m3/s from the Velino River, are carried out through 194,000 hectares within the territory of 42 municipalities of the Rieti Province. The Rieti Land Reclamation Authority contributes to the irrigation needs and to the environmental and hydrogeological protection and monitoring.

    Disturbances in Canada's boreal forest occur in both upland forests and in peatlands. These disturbances originate from both anthropogenic and natural causes, particularly fire. Techniques for the restoration, as well as the reclamation of peatlands and forests impacted by agriculture, urban development, or oil and gas activities, have made significant advancement over the last decade and these techniques need to be incorporated into the regulation and management of peatland and forest ecosystems. This symposium addressed the issue of how this research is affected by climate change. The sessions were entitled: (1) reclaiming forest and forest soils impacted by oil and gas production, (2) influence of oil sands development on forest communities, (3) understanding the importance of peatland and forest carbon in the twenty-first century, (4) reclaiming wetlands on mined oil sands tailing, (5) disturbance in peatlands and its relevance to minimizing disturbance footprints and informing reclamation efforts, and (6) restoration and management of harvested peatlands. The symposium featured 37 presentations, of which 6 have been catalogued separately for inclusion in this database. refs., tabs., figs.

  2. Evaluation of the seasonal performance of a water reclamation pond-constructed wetland system for removing emerging contaminants.

    2012-01-01

    The capacity of a full-scale reclamation pond-constructed wetland (CW) system to eliminate 27 emerging contaminants (i.e. pharmaceuticals, sunscreen compounds, fragrances, antiseptics, fire retardants, pesticides, and plasticizers) and the seasonal occurrence of these contaminants is studied. The compounds with the highest concentrations in the secondary effluent are diclofenac, caffeine, ketoprofen, and carbamazepine. The results show that the constructed wetland (61%) removes emerging contaminants significantly more efficiently than the pond (51%), presumably due to the presence of plants (Phragmites and Thypa) as well as the higher hydraulic residence time (HRT) in the CW. A greater seasonal trend to the efficient removal of these compounds is observed in the pond than in the CW. The overall mass removal efficiency of each individual compound ranged from 27% to 93% (71% on average), which is comparable to reported data in advanced treatments (photo-fenton and membrane filtration). The seasonal average content of emerging contaminants in the river water (2488 ng L(-1)) next to the water reclamation plant is found to be higher than the content in the final reclaimed water (1490 ng L(-1)), suggesting that the chemical quality of the reclaimed water is better than available surface waters.

    The problems connected to ground water dynamics take place in various areas of the people economic activity. For want of it in some branches the greatest interest rep- resents creation of quantitative parameters of a water mode, in one cases - of a level mode H(t) (land reclamation, agricultural and forest economy, ecology), in other - cre- ation of water discharge Q (t) (water-intakes for a water-supply or on the contrary - protective system from mines and quarry submerge). In a number of branches the ex- treme interest is represented by ground water quality dynamics (potable water-supply, inflow to rivers and lakes used for fish-breeding etc.). Each from these cases requires the account of features for want of creation of ground water dynamics models, re- alization of monitoring for their identification. With allowance for aid above in the report, the problems connected to ground water dynamics are bro-ken on three types: 1) evaluations of the system state and matching with normative parameters or match- ing of various objects among themselves; 2) prognosises of dynamics of ground water amount and quality; 3) problems of decision making support (optimization of ground water management), formalized as: The analysis is conducted for each of them and the conditions of choice of a generality level of a variable state describing ground stream dynamics (soil humidity, ground wa- ter level, water volume in the camera) and alternate variants, appropriate to them, of models describing water dynamics are shown: physical with the distributed parameters (equation of joint filtering of the bicomponent environment water-air, water-transfer equation, Boussinesk equation; with lumped parameters (chamber model with cam- eras of a various degree aggregating down to "a black box"), and also non-physical (statistical, regressive and neural networks) model.

    This report describes work conducted on the Building Materials Reclamation Program for the period of September 2008 to August 2010. The goals of the project included selecting materials from the local construction and demolition (C&D) waste stream and developing economically viable reprocessing, reuse or recycling schemes to divert them from landfill storage. Educational resources as well as conceptual designs and engineering feasibility demonstrations were provided for various aspects of the work. The project was divided into two distinct phases: Research and Engineering Feasibility and Dissemination. In the Research Phase, a literature review was initiated and data collection commenced, an advisory panel was organized, and research was conducted to evaluate high volume C&D materials for nontraditional use; five materials were selected for more detailed investigations. In the Engineering Feasibility and Dissemination Phase, a conceptual study for a regional (Mecklenburg and surrounding counties) collection and sorting facility was performed, an engineering feasibility project to demonstrate the viability of recycling or reuse schemes was created, the literature review was extended and completed, and pedagogical materials were developed. Over the two-year duration of the project, all of the tasks and subtasks outlined in the original project proposal have been completed. The Final Progress Report, which briefly describes actual project accomplishments versus the tasks/subtasks of the original project proposal, is included in Appendix A of this report. This report describes the scientific/technical aspects (hypotheses, research/testing, and findings) of six subprojects that investigated five common C&D materials.

    2013-01-01

    Full Text Available China, as a large agricultural country as well as a major country with great demand for grain, has played a more and more important role in the international grain market. As Northeast China is one of the major commodity grain bases in China as well as one of the regions with the highest intensity of human activities, it plays an important role in influencing the global food security. This study first generally analyzed the cultivated land reclamation and the climate change of temperature and precipitation in Northeast China during 2000–2010. Then, on the basis of these data, the climatic effects of cultivated land reclamation in Northeast China during 2030–2040 were simulated by the weather research forecast (WRF model. Finally, the possible effects of the climate change on the grain yield and the potential influence on the food security were analyzed. The simulation result indicated that the temperature in Northeast China would be increasing on the whole, while the precipitation would be decreasing. The result of this study can provide some theoretical support to the agricultural economic development in Northeast China and serve the national macropolicy and food security strategy of the whole China.

    Monitored composing was studied as a method for reducing the quantity of waste requiring disposed from a landfill reclamation project. After each of two re-screening steps, composted {open_quotes}soil{close_quotes} from a single long windrow of varying depths and moisture content was subjected to analytical testing to determine its suitability to remain as backfill in a reclaimed landfill site. The remaining uncomposted waste was combusted at a waste-to-energy facility to determine if Btu values were improved. Results indicate that a full-scale composting operation could result in a net decrease of approximately 11 percent in disposal costs. The Btu value of the reclaimed waste was calculated to be 4,500 to 5,000 Btu/lb. The feasibility of composting reclaimed waste at other landfill reclamation projects will depend upon site-specific technical and economic factors, including size and nature of the organic fraction of the waste mass, local processing costs, and the cost of waste disposal alternatives.

    Recent improvements in the management of oil sand tailings used by the Canadian oil sand industry have resulted in the production of composite tailing sands (CT): a new challenging material for reclamation work. Jack pine (Pinus banksiana Lamb.), hybrid poplar (Populus deltoides Bartr. ex Marsh. xPopulus nigra L.) and red clover (Trifolium pratense L.) plants were used in an 8-week greenhouse bioassay to evaluate the mycorrhizal inoculum potential of CT. This inoculum potential was compared with that of three other reclamation materials [common tailing sands (TS), deep overburden (OB) and muskeg peat (MK)], and with three sites reclaimed in 1982 (R82), 1988 (R88) and 1999 (R99). CT was devoid of active mycorrhizal propagules while all other materials showed some level of inoculum potential. Arbuscular mycorrhizal fungi were observed on roots of clover or poplar grown in TS, OB, and all substrates containing peat (MK, R82, R88 and R99). Pine roots were also colonized by vesicle-forming hyphae of an unidentified fine endophyte and by dark septate fungi. Ectomycorrhizas (ECM) were observed on pine and poplar grown in OB, MK, and in soils from the two older reclaimed sites (R82 and R88). Using morpho- and molecular typing, six ECM fungi were identified to the genus or species level: Laccaria sp., Thelephora americana, Wilcoxina sp. (E-strain), Tuber sp. (I-type), a Sebacinoid, and a Pezizales species. Laccaria sp. and Wilcoxina sp. were the most frequently observed ECM species.

    Full Text Available The history of the kitchen has received much attention from designers and design historians. Since the writings of Catharine Beecher, designers, household engineers, and others have written about the importance of the kitchen as the center of the home. This research traces the impact of the writings of theorists such as Frederick Taylor, Georgie Boynton Child, Helen Binkerd Young, and Christine Frederick on the designs produced by the architects in the first quarter of the 20th century.  Frederick’s work took the concept of an efficient kitchen to a new level applying movement studies and introducing new ideas to the kitchen layout and arrangement.  In a properly laid out and equipped kitchen, steps were saved by placing kitchen cabinets, ovens and stoves, refrigerators and sinks where they were needed in the sequence of food preparation and delivery to dining table as well as clean up after the meal.  In her books, she also provided advice on a variety of considerations, such as appliances and accessories, lighting and ventilation; materials, finishes and color; and appliances and equipment.  In 1919 a group of architects dedicated to improving the housing stock in the United States through good design banded together to form the Architects’ Small House Service Bureau (ASHSB.  Their first plan book, How to Plan Finance and Build your Home published in 1921, also encouraged labor-saving kitchen design and provided advice on kitchen design. The research reported here assesses how the influence of Frederick and Boyton’s advice as reflected in the work of and interpreted by Helen Binkerd Young is demonstrated in the kitchen designs of the ASHSB’s first plan book. A plan content analysis instrument, developed using Frederick’s writings and edited to include other variables from Young and Child, is used to analyze the 99 kitchens and two essays in the ASHSB’s plan book.  The plans and accompanying comments evidence enthusiasm for

    Losari Beach is the most important site in Makassar. It lies at the west side of Makassar city. This place is known as the place where people are relaxed and gathering with friends or family after working, and now it becomes the icon of Makassar city. As the biggest city in eastern Indonesia, Makassar grows very fast. We can find constructions for building hospitals, shopping malls, bussines activities, and residences everywhere. The most important construction activities that will effect Losari Beach is the reclamation to build the Center Point of Indonesia that takes an area of 157 hectares and it is located at the west side of Losari Beach. In the last research presented in 9th International Conference on Marine Technology (October 2014) using surface-water modeling system (SMS) software showed that reclamation will significantly increase concentrations of BOD and COD (± 7 mg/L for BOD and 6.2 mg/L for COD). This condition will cause Losari Beach becomes very polluted. A probable solution to overcome this problem is to clean the wastewater before introducing to the sea. This paper will describe the type of the wastewater treatment plant that can be used to solve the water pollution problem in Losari Beach.

    Full Text Available In order to research the effects of landscape pattern and ecological effects caused by homestead land reclamation in hilly and mountainous regions of southwest China, taking land reclamation project of homestead in Dazhu Village, Qiantang Town, Hechuan District of Chongqing City as an example, the land use structure and landscape pattern changes were studied based on ArcGIS and methods of landscape ecology. The ecological effects were evaluated with an indices system which was constructed with optimized landscape pattern and the weight assigned for each index by AHP (analytic hierarchy process method. The results showed that the ecological environment was improved as a result of homestead land reclamation project. Almost of the evaluation index, such as length and density of corridor and ecological services value, had positive effects on ecosystem. But the dominance index and fractal dimension index had negative effects. In conclusion, the rural scattered residential areas were concentrated to some extent by implement of the homestead land reclamation project, which saved the rural residents living area to provide the land utilization index for urban and rural construction and conducive to the development of new rural construction and rural ecological civilization construction.

  18. The position of the Bureau of International Recycling on unwanted radioactivity and scrap

    1999-01-01

    The Bureau of International Recycling (BIR) speaks as the unified voice of the international recycling industry on a world level, promoting free-trade in non-hazardous recyclables and the increased usage of recycled goods. In October 1998, BIR presented its 'Guide to Radioactivity' to its members in order to explain the basics of radioactivity, to help determine what actions material recyclers should take and to provide an initial contact guide for summoning expert help. The Guide was promulgated together with a survey questionnaire; initial results of this survey have been collated. BIR members do not trade in radioactive materials and do not wish to receive hazardous radioactive contaminated materials. Furthermore it is very uncommon to find this unwelcome and unwanted material. The burden of handling contaminated materials should not rest on the recycling industry alone, however, as the hazards associated with processing contaminated materials are potentially extreme, recyclers have a role to help safeguard both their workforce and subsequent customers. Some BIR members have invested in in-plant detection equipment of various types from a variety of suppliers to detect contamination from 'lost' sources or from naturally occurring radioactive materials (NORM). Strict State control on sources in use would be very welcome to limit these ' losses'. Not all BIR members are in a position to provide or operate detection equipment; therefore, BIR would welcome States providing detection and control at sea ports and at border checkpoints on railways and roads. Some states have proposed permitting requirements for the handling of radioactive contaminated materials and have tried, inappropriately, to impose on the mainstream recycling industry, permits designed for the specialist decontamination or decommissioning industry. Current discussions on applying the transport of dangerous goods regulations would lead to unnecessary and impracticable additional restraints to

    Bedrock strata of the mining district of Indiana (Indiana Coal Mining District, ICMD) include numerous coalbeds of economic importance, together with underclays, roof shales, limestones, and sandstones of Pennsylvanian age. These are typically poor aquifers with low hydraulic conductivities and specific yields. Surficial materials include loess, till, alluvium, and other deposits of pleistocene age. The loess and till also have low hydraulic conductivities, so that very few shallow aquifers exist in the vicinities of abandoned mine land (AML) sites, except where they are close to the alluvial fill of large bedrock valleys. The hydrologic cascade at AML sites in Indiana is strongly conditioned by the existence of elevated deposits of coarse-grained coal-preparation refuse and flooded underground mine workings. Flooded mines are the principal conduits of groundwater flow in the area, but their boundaries, flowpaths, and mechanisms of recharge and discharge are very different from those of natural aquifers and are poorly understood. Acidic mine drainage often emerges as seepages and springs on the edges of the elevated refuse deposits, but the low permeability of the natural surficial materials and bedrock inhibits the development of off-site groundwater contaminant plumes. The water balance across the surface of the refuse deposits is critical to reclamation planning and success. Enhancing runoff through reduction of infiltration capacity has the beneficial effect of reducing recharge through the acid-generating refuse, but the excess runoff may be accompanied by soil erosion that can lead to reclamation failure. Furthermore, during cool seasons and stormy periods, a well vegetated surface promotes recharge through increased infiltration, resulting in greater rates of acidic baseflow seepage. Passive Anoxic Limestone Drains (PALDs) have been successfully coupled with wetland treatment systems to improve surface waters that discharge from AML sites. Storm runoff from

    2000-06-01

    Under the direction of Cecilia Payne-Gaposchkin and Sergei Gaposchkin, a program was subsidized by the Milton Fund of Harvard Observatory in 1937 for the study of all variable stars then known to be brighter than tenth photographic magnitude at maximum. This included some 1512 stars for which a grand total of 1,263,562 estimates of magnitude were made, ranging from a low of 16 (except for a few novae) to 4084 observations per star. The sky had been divided into 54 fields, and the results of the measurements presented field by field in two volumes of the Annals of Harvard Observatory. Then, in another volume, the results were discussed in four sections, each dealing with a particular class of variable: 1, those of RV Tauri type; 2, the eclipsing variables; 3, Cepheids and RR Lyrae variables, and 4, the red variables, especially Mira-type and semiregular variables. For the present paper, many of these results have been compared with modern determinations in the 1985-87 version of the "General Catalogue of Variable Stars (GCVS)". In particular, there are numerous instances of disagreement as to whether a star should be classified RV or SR. Although there are many instances where the Milton Bureau determinations of types of variability differ from the types given in modern catalogues, the reasons for the differences are generally understandable. For 17 RV Tauri type stars in this survey multiple periods have now been determined. Many of these still deserve continued observations in order to ascertain the constance of the periods and improve the accuracy of their longest reported periods.

    Full Text Available Large-scale reclamation projects during the past decades have been recognized as one of the driving factors behind land subsidence in coastal areas. However, the pattern of temporal evolution in reclamation settlements has rarely been analyzed. In this work, we study the spatio-temporal evolution pattern of Linggang New City (LNC in Shanghai, China, using space-borne synthetic aperture radar interferometry (InSAR methods. Three data stacks including 11 X-band TerraSAR-X, 20 L-band ALOS PALSAR, and 35 C-band ENVISAT ASAR images were used to retrieve time series deformation from 2007 to 2010 in the LNC. An InSAR analysis from the three data stacks displays strong agreement in mean deformation rates, with coefficients of determination of about 0.9 and standard deviations for inter-stack differences of less than 4 mm/y. Meanwhile, validations with leveling data indicate that all the three data stacks achieved millimeter-level accuracies. The spatial distribution and temporal evolution of deformation in the LNC as indicated by these InSAR analysis results relates to historical reclamation activities, geological features, and soil mechanisms. This research shows that ground deformation in the LNC after reclamation projects experienced three distinct phases: primary consolidation, a slight rebound, and plateau periods.

    Artificial recharge and reclamation of stormwater into groundwater is a newly developing strategy to augment water resources in the Adelaide metropolitan area of South Australia. Mixing between injected storm water and native groundwater can be most effectively using naturally occurring chloride ion. Stable isotopes of the water molecule are used more effectively during short term tests (i.e., immediately following injection events), and requires frequent monitoring of the surface water end-member. Biogeochemical processes involving geochemical reactions such as organic matter oxidation, carbonate mineral dissolution and sulfide mineral oxidation are very effectively traced by δ 13 C and 14 C (of TDIC) and δ 34 S (of SO 4 2- ). The most important processes occurring in the Tertiary limestone aquifer in Adelaide were carbonate mineral dissolution which is induced largely by CO 2 production during organic matter oxidation. Sulfide mineral oxidation is a minor process, and is accompanied by an equivalent amount of sulfate reduction after injection of the stormwater. (author)

    Visual evaluation of chest radiograph images is the most practical and effective method. This study compared the Body Mass Index, waist circumference, and mAs with chest radiographs of 351 women. The Bureau of Radiological Health method was used to evaluate the image quality of chest X-ray images by anatomical and physical methods. The average age of the subjects was 30.17±4.73 and the average waist circumference was 66.91±4.67 cm. The mean Body Mass Index value was 20.21±2.23, the mean value of mAs was 3.04±0.78, and the mean value of Bureau of Radiological Health was 79.83±8.45. When the Body Mass Index value increased, waist circumference and mAs mean value increased. The mean value of Body Mass Index was statistically significant(p<0.05) in Group 4 compared to Groups 1 and 2, with increasing Body Mass Index. Exposure control of the automatic exposure control system is considered to be well performed according to body thickness or Body Mass Index at the time of chest radiography. As the Body Mass Index increases, the thickness of the body increases and the breast thickness of the woman also increases. Therefore, it is considered that the exposure amount is changed by the automatic exposure control device to affect the image quality.

  9. Waste acid detoxification and reclamation

    1988-01-01

    Economically feasible processes that reduce the volume, quantity, and toxicity of metal-bearing waste acids by reclaiming, reusing, and recycling spent acids and metal salts are being developed and demonstrated. The acids used in the demonstrations are generated during metal-finishing operations used in nuclear fuel fabrication; HF-HNO 3 , HNO 3 , and HNO 3 -H 2 SO 4 wastes result from Zr etching, Cu stripping, and chemical milling of U. At discharge, wastes contain high concentrations of acid and one major metal impurity. The waste minimization process used to reclaim acid from these three streams incorporates three processes for acid regeneration and reclamation. Normally, HNO 3 remains in the bottoms when an aqueous acid solution is distilled; however, in the presence of H 2 SO 4 , HNO 3 will distill to the overhead stream. In this process, nitrates and fluorides present as free acid and metal salts can be reclaimed as acid for recycle to the metal-finishing processes. Uranium present in the chemical milling solution can be economically recovered from distillation bottoms and refined. Using acid distillation, the volume of chemical milling solution discharged as waste can be reduced by as much as 60% depending on the H 2 SO 4 concentration. A payback period of 2.2 years has been estimated for this process. The development and demonstration of precipitation and distillation processes for detoxification and reclamation of waste acid is supported by the US Department of Energy's Hazardous Waste Remedial Actions Program (HAZWRAP)

    2007-01-01

    The paper deals with a suitability analysis of waste rock application in hydric reclamation on the basis of studying its impact on water quality in the natural water-bearing subsidence troughs. The evaluation was carried out in sixteen localities where waste rock had been used in the past for the purposes of bank system improvement. Within the evaluation of waste rock impact on the hydrochemical character of water in the subsidence troughs the values of geochemical background were identified. In order to compare the impact of waste rock on the quality of water, changes in the hydrochemical parameters were monitored in the localities without waste rock banking, with partial (maximum 1/2 circumference) and complete waste rock banking.

    1977-02-01

    A mountain-top removal coal mining operation in south-central West Virginia is examined in this case study. A 2010 acre tract that is partly owned and partly leased by Cannelton Industries, Inc., has been about half stripped of the 5 Block and 6 Block Coals. The surrounding land area is characterized by steep-sided hills and generally lacks extensive tracts of level land suitable for agricultural or residential/commercial development. The Cannelton operation, which has already leveled several ridges, is creating areas which may be considered to have a higher land use potential than before mining. Although this site is generally isolated from urbanized areas and thus from structured regional planning efforts, it merits study as an excellent example of an innovating mining technique and integrated site-specific mining and reclamation planning.

    1991-01-01

    The US DOE is required by law and other regulatory requirements to reclaim disturbances created by site characterization activities at Yucca Mountain. Because of the difficulty of reclaiming arid areas and the lack of site specific information on successful reclamation techniques and procedures, the DOE has developed a comprehensive reclamation program. The program consists of three phase: Planning, operational and research. The planning phase is a continuing process that ensures that program policy, goals, tasks and responsibilities are clearly identified and linked. Three inter-related planning documents have been released by the DOE that establish the program objectives and outline the steps needed to successfully meet those objectives. The operational phase uses best available knowledge to develop and implement reclamation plans that are site-specific for each disturbance. Reclamation activities start prior to any surface disturbance with a survey of each disturbance by trained scientists. The scientists survey the area for the presence of protected species or critical wildlife habitat. They also gather vegetation, landscape, soils and other environmental data that is used to assess the impact of the proposed disturbance. Recommendations can be made to either avoid areas or mitigate impacts. The operational phase includes interim reclamation to protect valuable resources and control erosion prior to final reclamation. Monitoring of reclaimed sites is conducted to correct problem areas and insure that reclamation objectives are achieved. The third phase of the reclamation program is designed to provide site-specific information on effective reclamation techniques through research and field demonstrations. Information on potentially successful techniques will be used to update to improve the effectiveness of the reclamation activities at Yucca Mountain

    Full Text Available The results are presented of vegetation survey on the alkaline and saline soda waste disposal site at Janikowo Soda Plant near Toruń (central Poland. The site was subject to reclamation using diverse techniques including sewage sludge and ash, starting from the year 2000 onwards. The survey was made to evaluate the status of plant succession as well as stability and diversity of vegetation cover. The vegetation was inventoried using the cover-frequency method, on a 10 x 10 m quadrat samples randomly distributed over the reclaimed area. Communities were classified using the Central-European approach by Braun-Blanquet (1964. In 2013, the vegetation was well established and provided a dense cover of the substrate. 108 plant species were found compared to some 5–8 plants which arrived spontaneously until the year 2000. Species richness increased 15 fold since the year when reclamation started. Species of graminoid and Asteraceae families prevailed in most patches of local vegetation. The vegetation cover on sites treated with a mixt of power plant ash and sewage sludge was less stable and less diverse than that on sites where sewage sludge only was applied. Annuals and biennials dominated in the vegetation on ash grounds while more competitive perennials prevailed on sewage sludge substrates. On the latter substrates there develop plant communities classified as an association of smooth meadow grass and common yarrow Poa pratensis-Achillea millefolium, whose species combination closely resembles that of seminatural fresh meadows. On the ash grounds, a variety of associations of ruderal plants were found with dominating Loesel mustard and common mugwort Sisymbrium loeselii-Artemisia vulgaris. Phytoindicatory methods using Ellenberg values have shown that waste substrates contained increased salt concentrations, however, there was no indication of increased heavy metal contents, as no plants tolerating excessive amounts of heavy metals were

    Rapid urbanization and reclamation processes in coastal areas have resulted in serious pollution to the aquatic environment. Less is known on the geochemical fractions and ecological risks in river sediment under various human activities pressures, which is essential for addressing the connections between heavy metal pollution and anthropogenic influences. River sediments were collected from different landscapes (i.e., urban, rural and reclamation areas) to investigate the impacts of urbanization and reclamation on the metallic pollution levels and ecological risks in the Pear River Estuary of China. Results showed that Cd, Zn and Cu with high total contents and geoaccumulation index (I geo ) were the primary metals in the Peal River sediments. Generally, urban river sediments, especially the surface sediment layer (0-10 cm), exhibited higher metallic pollution levels. As for geochemical fractions, reducible and residual fractions were the dominant forms for six determined metals. And the percentage of heavy metals bound to Fe-Mn oxides decreased with increasing soil depth but the reverse tendency was observed for residual fractions. Compared with rural river sediments, heavy metals were highly associated with the exchangeable and carbonate fractions in both urban and reclamation-affected river sediments, suggesting that anthropogenic activities mainly increased the active forms of metals. Approximately 80% of Cd existed in the non-residual fraction and posed medium to high ecological risk according to the risk assessment code (RAC) values. The redundancy analysis (RDA) revealed that both urbanization and reclamation processes would cause similar metallic characteristics, and sediment organic matter (SOC) might be the prominent influencing factor.

    2014-01-01

    This study describes an approach for surface modification of a nonwoven membrane by diatomite/iron oxide to examine its filterability. Analysis results showed that nonwoven hydrophilicity is enhanced. Static contact angle decreases dramatically from 122.66° to 39.33°. Scanning electron micrograph images show that diatomite/iron oxide is attached on nonwoven fiber. X-ray diffraction analysis further proves that the compound is mostly magnetite. Fourier transformed infrared spectra results reveal that two new absorption peaks might be attributed to Si-O and Fe-O, respectively. Modified and original membranes were used in double nonwoven membrane bioreactors (MBRs) for synthetic wastewater treatment. High critical flux, long filtration time, slow trans-membrane pressure rise and stable sludge volume index confirmed the advantages of modified nonwoven. Comparing with original nonwoven, similar effluent qualities are achieved, meeting the requirements for wastewater reclamation.

    Four experiments were conducted to examine the competitive effects of introduced annual weeds on certain native and reclamation species. The first experiment was initiated by discing three sites in the Powder River Basin, Wyoming, at three distances from introduced weed seed sources. Introduced weed colonization was greatest when a seed source was located nearby. Higher weed cover resulted in reductions of percent cover, density, and richness of the native species. The second experiment was conducted in the greenhouse and was designed to determine if there are changes in response of S. kali and the native grasses Agropyron smithii and Bouteloua gracilis to competition and water regime. Both grass species had lower biomass and higher stomatal resistance when growing in mixed culture with S. kali than in pure culture in the dry regime, but there were no significant differences in the wet regime. In general, the difference in plant response between mixed and pure cultures was more pronounced in the dry than in the wet regime. The third study was a greenhouse experiment on germination and competition of S. kali (a C/sub 4/ species) with native species Lepidium densiflorum (C/sub 3/), Chenopodium pratericola (C/sub 3/), A. smithii (C/sub 3/), and B. gracilis (C/sub 4/) under May, June, and July temperature regimes. Salsola kali germinated equally well in all three regimes, but the other C/sub 4/ species had highest germination in the July regime and the C/sub 3/ species in the May and June regimes. The fourth study was designed to examine the effect of weed colonization on the success of mine reclamation. Little effect was observed, but colonization by introduced annuals was very low. (ERB)

    The Bureau for Revising Medical Books was a temporary agency established by the government of the Northern Song Dynasty in 1057, the 2nd year of Jiayou of Emperor Renzong, exclusively for the edition, revision and publishing of ancient medical books. 11 medical books were revised and edited by 13 Bureau members in a period of 12 years until 1069, the 2nd year of Xining of Emperor ShenZong, which eventually became the final versions until today. 8 medical books were initially planned for the revision, but 11 were actually completed in the end. The time for completing a revision varied from over 10 years at most to less than 1 year at least. Instead of working in the office, the officers of the Bureau for Revising Medical Books did their works at home. The members of the said Bureau came from the Tiju officer of the Bureau for Revising Medical Books and the officials of revising medical books, consisting of both Confucian ministers and medical officers. Confucian ministers played an important role in revising medical books. The Bureau had a strict workflow in electing revising officials, making the project, and the determination of the principles and arrangements of the tasks of editing and proofreading.

    The Argonne Land Reclamation Program, sponsored by the United States Department of Energy's Assistant Secretary for Environment, is a joint effort of two Argonne divisions: Energy and Environmental Systems and Environmental Impact Studies. The program is carried out by a multidisciplinary team of scientists and engineers and has three primary objectives: (1) to develop energy-efficient and cost-effective mining and reclamation techniques; (2) to assist industry in evaluating the viability of environmental regulations and demonstrating techniques to meet these regulations; and (3) to supply data and evaluation techniques to decisionmakers concerned with trade-offs between energy development and environmental quality. Six integrated field research sites have been established to address problems associated with surface mining operations. This program relies heavily on input from industry and has developed working arrangements with coal companies at each of the current mining sites. A major area of interest is the development of a ten-year environmental mining and reclamation research plan for the Assistant Secretary for Environment. The Land Reclamation Program assigns the highest priority to the transfer to users of information generated by its research.

    Fragmented structures create metaphorical wounds in the landscape altering the ecological and cultural processes associated with it, as it can be seen in many mine areas. Therefore it is advisable to organize the reclamation plan in the beginning of mine operating to provide spatial and functional integration of the landscape based on scientific arguments and with all possible legal and administrative means, which is generally the case of the Strategic Environmental Assessment. However, there are many abandon mine areas where no reclamation plan has been carried out, such as the case of Mining District of Sierra Minera Cartagena-La Unión, SE Spain. In these cases it is vital to respond in a sustainable manner for healing the landscape wounds of post-mining activities. Reclamation activities of a post-mining district includes not only the mine soils also all land uses around them, for this reason on necessary create practical solutions for returning the functions of ecologic and cultural processes of the area. Greenway approach shows the main veins which are crucial for keeping alive and sustaining the mentioned processes of the area. Therefore the main objectives of this study are to 1) develop an integrated local greenway network to be able to preserve significant resources and values of the district, and to 2) develop this greenway network as a part of reclamation process for degraded areas. Landscape assessments revealed the most valuable and potential connectivity resources of the area. These clustering and linear patterns of resource concentrations include mountain range and valleys, natural drainage network, legally protected areas and cultural-historical resources. Conservation areas, cultural-educational resources of post-mining activities and the riverbeds have been the main building stones for the greenway corridor. The multifunctional greenway approach serves as landscape reclamation and planning tool in a degraded area by showing the priority zones for

    The effect of reclamation on heavy metal concentrations and the ecological risks in ditch wetlands (DWs) and riparian wetlands (RWs) across a 100-year chronosequence in the Pearl River Estuary of China was investigated. Concentrations of 4 heavy metals (Cd, Cu, Pb, and Zn) in soil and plant samples, and sequential extracts of soil samples were determined, using inductively coupled plasma atomic absorption spectrometry. Results showed that heavy metal concentrations were higher in older DW soils than in the younger ones, and that the younger RW soils contained higher heavy metal concentrations compared to the older ones. Although the increasing tendency of heavy metal concentrations in soil was obvious after wetland reclamation, the metals Cu, Pb, and Zn exhibited low or no risks to the environment based on the risk assessment code (RAC). Cd, on the other hand, posed a medium or high risk. Cd, Pb, and Zn were mainly bound to Fe–Mn oxide, whereas most of Cu remained in the residual phase in both ditch and riparian wetland soils, and the residual proportions generally increased with depth. Bioconcentration and translocation factors for most of these four heavy metals significantly decreased in the DWs with older age (p < 0.05), whereas they increased in the RWs with younger age (p < 0.05). The DW soils contained higher concentrations of heavy metals in the organic fractions, whereas there were more carbonate and residual fractions in the RW soils. The non-bioavailable fractions of Cu and Zn, and the organic-bound Cd and Pb significantly inhibited plant growth. - Highlights: • Heavy metals in ditch wetland accumulated with increasing reclamation history. • Heavy metals exist in the Fe–Mn oxides and residual fractions in both wetlands. • Cd posed a medium to high environmental risk while low risk for other metals. • Long reclamation history caused lower BCFs and TFs in DWs and higher levels in RWs. • RW soils contained more heavy metals in the carbonate

    Conventional reclamation interventions of post-smelting slag dumps being undertaken so far either failed or produced poor results. Certain lichens, especially of the genus Cladonia, are known as effective colonisers of bare ground in anthropogenic habitats. The paper presents preliminary results of the experiment aimed at the evaluation of lichen usefulness in reclamation interventions. The cultivation in vivo involving transplantation of lichens directly on slag substrate was established in 2015. Five species, i.e. Cladonia rei, C. cariosa, C. pyxidata, C. subulata, C. macilenta, were transplanted into 32 cuvettes filled with sterilised slag substrate. The sample weight of 2 and 6 g were used and half of cuvettes were regularly supplied with 2% malt solution. The first important symptoms at the present stage of the experiment are as follow: the growth of thalli has appeared only in the case of first three species; C. rei shows the most effective development; cuvettes with 6 g sample weight are characterized by higher coverage of fresh lichen thalli; lichen biomass are visually higher in cuvettes treated with malt solution. The results give us reason to believe that lichens could be successfully used as an alternative element during planning of slag dumps reclamation in the future.

    In 1882, the director of the Córdoba Observatory became involved in a debate over international missions that were observing the transit of Venus across the sun, criticizing them for doing "harm to science, leaving substance aside in search of a shadow." The governor of Buenos Aires province and members of France's Bureau of Longitudes fostered these missions, and the instruments they used would serve in the founding of the local observatory in La Plata. The Córdoba observatory's second director would later state that the work carried out in La Plata had been as useful as "a single well bucket in irrigating the area covered by Córdoba's canals." The article reveals the hidden rivalry between international networks engaged in mutual accusations and the ensuing disputes between institutions.

    Canadian fire weather index system (FWI) is the most widely used fire weather index system in the world. Its fuel moisture prediction is also a very important research method. In this paper, litter moisture contents of typical forest types in Tahe Forestry Bureau of Northeast China were successively observed and the relationships between FWI codes (fine fuel moisture code FFMC, duff moisture code DMC and drought code DC) and fuel moisture were analyzed. Results showed that the mean absolute error and the mean relative error of models.established using FWI moisture code FFMC was 14.9% and 70.7%, respectively, being lower than those of meteorological elements regression model, which indicated that FWI codes had some advantage in predicting litter moisture contents and could be used to predict fuel moisture contents. But the advantage was limited, and further calibration was still needed, especially in modification of FWI codes after rainfall.

    Reclaimed salt marshes are fragile environments where water salinization and accumulation of heavy metals can easily occur. This type of environment constitutes a large part of the Po River Delta (Italy), where intensive agricultural activities take place. Given the higher Ni background of Po River Delta soils and its water-soluble nature, the main aim of this contribution is to understand if reclamation can influence the Ni behavior over time. In this study, we investigated the geochemical features of 40 soils sampled in two different localities from the Po River Delta with different reclamation ages. Samples of salt marsh soils reclaimed in 1964 were taken from Valle del Mezzano while soils reclaimed in 1872 were taken nearby Codigoro town. Batch solubility tests and consecutive determination of Ni in pore-water were compared to bulk physicochemical compositions of soils. Bulk Ni content of the studied soils is naturally high, since these soils originated from Po River sediments derived from the erosion of ultramafic rocks. Moreover, it seems that Ni concentration increases during soil evolution, being probably related to the degradation of serpentine. Instead, the water-soluble Ni measured in the leaching tests is greater in soils recently reclaimed compared to the oldest soils. Soil properties of two soil profiles from a reclaimed wetland area were examined to determine soil evolution over one century. Following reclamation, pedogenic processes of the superficial horizons resulted in organic matter mineralization, pH buffer, and a decrease of Ni water solubility from recently to evolved reclaimed soil.

    The reconstruction of disturbed landscapes back to working ecosystems is an issue of increasing importance for the oil sand areas in Alberta, Canada. In this context, the fate of oil-sand-derived organic material in the tailings sands used for reclamation is of utmost environmental importance. Here we use electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry of maltene fractions to identify compositional variations over a complete oil sand mining and recultivation process chain. On the basis of bulk compound class distributions and percentages of unique elemental compositions, we identify specific compositional features that are related to the different steps of the process chain. The double bond equivalent and carbon number distributions of the N1 and S1O2 classes are almost invariant along the process chain, despite a significant decrease in overall abundance. We thus suggest that these oil-sand-derived components can be used as sensitive tracers of residual bitumen, even in soils from relatively old reclamation sites. The patterns of the O2, O3, and O4 classes may be applied to assess process-chain-related changes in organic matter composition, including the formation of plant-derived soil organic matter on the reclamation sites. The N1O2 species appear to be related to unidentified processes in the tailings ponds but do not represent products of aerobic biodegradation of pyrrolic nitrogen compounds.

    Full Text Available Over the past six decades, coastal wetlands in China have experienced rapid and extensive agricultural reclamation. In the context of saline conditions, long-term effect of cultivation after reclamation on soil chemical properties has not been well understood. We studied this issue using a case of approximately 60-years cultivation of a coastal saline marsh in Bohai Rim, northern China. The results showed that long-term reclamation significantly decreased soil organic carbon (SOC (-42.2% and total nitrogen (TN (-25.8% at surface layer (0-30 cm as well as their stratification ratios (SRs (0-5 cm:50-70 cm and 5-10 cm:50-70 cm. However, there was no significant change in total phosphorus (TP as well as its SRs under cultivation. Cultivation markedly reduced ratios of SOC to TN, SOC to TP and TN to TP at surface layer (0-30 cm and their SRs (0-5 cm:50-70 cm. After cultivation, electrical conductivity and salinity significantly decreased by 60.1% and 55.3% at 0-100 cm layer, respectively, suggesting a great desalinization. In contrast, soil pH at 20-70 cm horizons notably increased as an effect of reclamation. Cultivation also changed compositions of cations at 0-10 cm layer and anions at 5-100 cm layer, mainly decreasing the proportion of Na+, Cl- and SO4(2-. Furthermore, cultivation significantly reduced the sodium adsorption ratio and exchangeable sodium percentage in plow-layer (0-20 cm but not residual sodium carbonate, suggesting a reduction in sodium harm.

    Sediments were collected to a depth of 20 cm from urban, rural, and reclamation-affected rivers in the Pearl River Delta of China. In total, 16 organochlorine pesticides (OCPs) were analyzed in all sediment samples, and the occurrence, possible sources, toxicity, and health risks of OCPs were evaluated to compare the contamination characteristics of OCPs in sediments among the three types of rivers. The results showed that concentrations of Σ16OCPs in sediments from the three rivers followed the order urban river > reclamation-affected river > rural river, with a mean value of 247.21, 232.91, and 114.92 μg/kg, respectively, and the predominant OCPs were hexachlorobenzene (HCB), dieldrin, aldrin, endrin, and hexachlorocyclohexanes (HCHs). Source diagnostics illustrated that there might be recent input of HCHs, dichlorodiphenyltrichloroethanes (DDTs), and endosulfan in some sampling sites. Based on the soil quality thresholds of China, both HCHs and DDTs fell within the range of class II criteria except for some sediment samples in urban rivers with lower levels (below class I criteria). According to sediment quality guidelines, 92.86 % of samples were predicted to be toxic. The health risk assessment showed that OCPs would not pose a threat to people via dermal contact, ingestion, and inhalation, and the followed order of incremental lifetime cancer risks for OCPs in sediment samples was reclamation-affected river > urban river > rural river.

    It is believed by recent releases of World Health Organization (WHO) that more than half of the world's population (3.2 billion) live in areas that are at risk of malaria transmission. Although increased efforts are dramatically reducing the malaria burden in some places where the rate of new cases indicates a fall by 37% globally and 60% death rate. Unfortunately, the subSaharan Africa still shares 89% of malaria and 91% of malaria deaths. Essentially, attacking the causative vectors and reclamation of the vector breeding sites could be remarkable for the rolling back the malaria epidemic project. Consequently, it is essential to explore the possibility of using recent Landsat-8 data remote sensing data and applications of Geographic Information System (GIS) technique in contributing to the realization of this objective. This investigation used for identifying mosquito breeding habitat (Derelict Ponds) zones the application of supervised classification of the Landsat-8 image in conjunction with GIS layering which allowed identification of high risk prone regions for mosquito breeding habitat. The methodology delineated 10 spatial locations of the Derelict Ponds (DP) spread around the Birnin Kebbi urban environment. Moreover, the results combined with comparative analysis of the link between warm climatic (temperature and rainfall data) conditions and Malaria prevalence that is associated with urban poverty. This study indicates that the application of Landsat-8 data and GIS techniques can be a useful tool for planning and management of environmental health and mapping of hot spot environmental problem areas.

    Landscape connectivity is an important indicator to measure effectiveness of landscape ecological services. Waterbody connectivity in Lianyun New City, the new reclamation region of Lianyungang, was investigated based on GIS technology and effective distance model. The results showed that the total connectivity of waterbodies was poor in Lanyun New City. Connectivity of patches was related to characteristics of ecological process, ecological services value and spatial arrangement. The higher the ecosystem services value of patches was, the greater its contribution to the overall water landscape connectivity was. Some patches with long strip structure played a key role to improve the landscape connectivity. By classifying the importance of connectivity and functional groups of waterbody patches, planning of waterbodies in Lianyun New City conformed to the theory of non-substitutable pattern developed by Forman. Waterbody patches with corresponding functions should be considered with priority when planning and building a new city. The present study demonstrated that connectivity of patches should be an important factor to be considered in ecological landscape planning. Construction of ecological corridors should not only take the number of ecological landscapes into consideration, but also pay attention to spatial arrangement of landscapes in order to improve the overall landscape connectivity.

    Vegetation plays a significant role in mass retention, solar energy dissipation, water cycle forming and local climate changes on reclamation plots of mining areas. This paper discussed the use of Landsat satellite data in order to evaluate different types of reclamation and their development for the last 20 years in the case of the Velka podkrusnohorska dump. Biophysical parameters which can be indicators of solar energy dissipation that were utilized to analyse changes of temporal development from 1991 to 2009 included land surface temperature, surface moisture expressed as wetness index tasseled cap, and normalized difference vegetation index. From these parameters, a functional index was then developed. The paper discussed the development of these parameters and their relationship to solar energy dissipation. It was concluded that since 1995, the observed parameters significantly changed, gradually converging to the state of the surrounding landscape. 16 refs., 2 tabs., 2 figs.

    Although reclamation techniques for forest ecosystems recovery have been developed over the past decades, there is still a great difficulty in the establishment on environment assessment, especially when compared to the non-disturbed ecosystems. This work evaluated the results and limitations on cassiterite-mined areas in reclamation, at Brazilian Amazônia. Floristic variables from 29 plots located on 15-year-old native species reforestation sites and two plots from preserved open/closed canopy forests were analyzed in a chronosequece way (2010-2015). Regeneration density, species richness, average girth, and average height were evaluated every year, by means of cluster analysis (Euclidian distance, Ward method) and submitted to multiscale bootstrap resampling (a=5%). It was conduced the regression analysis for each identified group in 2015 in order to verify differences between the chronosequece development. The results showed the existence of two main groups in 2010, one witch all mined plots were allocated and other with open/closed canopy plots. After 2011 some mined areas became allocated in the open/closed canopy plots group. From 2013 and on open/closed canopy plots appeared shuffled in the formed groups, indicating the reclamation sites conditions became similar to natural areas. Finally, in 2015 three main groups were formed. The regression analysis showed that group three had a higher trend of development for regeneration density, with higher angular coefficient and higher values. For species richness all the groups had a similar trend, with values lower than open/closed canopy forest. In average girth higher trends were observed in group one and all values were near to open canopy forest in 2015. Average height showed better trends and higher values in group two. It was concluded that all mined sites had a forest recovery process. However, different responses to reclamation process were observed due to the differences in the degraded soils

    This document contains summary reports of stream habitat surveys, conducted in the Cowlitz River basin, by the Bureau of Fisheries (BOF, now National Marine Fisheries Service) from 1938--1942. These surveys were part of a larger project to survey streams in the Columbia River basin that provided, or had provided, spawning and rearing habitat for salmon and steelhead. The purpose of the survey was to determine the present condition of the various tributaries with respect to their availability and usefulness for the migration, breeding, and rearing of migratory fishes. Current estimates of the loss of anadromous fish habitat in the Columbia River Basin are based on a series of reports published from 1949--1952 by the US Fish and Wildlife Service

    Full Text Available The effect of gypsum on the physical and chemical characteristics of sodic soils is nonlinear and controlled by multiple factors. The support vector machine (SVM is able to solve practical problems such as small samples, nonlinearity, high dimensions, and local minima points. This paper reports the use of the SVM regression method to predict changes in the chemical properties of sodic soils under different gypsum application rates in a soil column experiment and to evaluate the effect of gypsum reclamation on sodic soils. The research results show that (1 the SVM soil solute transport model using the Matlab toolbox represents the change in Ca2+ and Na+ in the soil solution and leachate well, with a high prediction accuracy. (2 Using the SVM model to predict the spatial and temporal variations in the soil solute content is feasible and does not require a specific mathematical model. The SVM model can take full advantage of the distribution characteristics of the training sample. (3 The workload of the soil solute transport prediction model based on the SVM is greatly reduced by not having to determine the hydrodynamic dispersion coefficient and retardation coefficient, and the model is thus highly practical.

    An integrated indicator system was developed for determining synthetic environmental responses under multiple types of coastal reclamation engineering in the Yellow River estuary, China. Four types of coastal engineering works were analyzed, namely port construction, petroleum exploitation, fishery and aquaculture, and seawall defense. In addition, two areas with limited human disturbances were considered for comparison. From the weights of the response value for each indicator, port construction was determined to be the primary impact contributor among the four engineering works studies. Specifically, hydrodynamic conditions, ecological status, economic costs, and engineering intensity were on average 72.78%, 65.03%, 75.03%, and 66.35% higher than those of other engineering types. Furthermore, fishery and aquaculture impact on water quality was 42.51% higher than that of other engineering types, whereas seawall defense impact on landscape variation was 51.75% higher than that of other engineering types. The proposed indicator system may provide effective coastal management in future. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The aim of this research is to evaluate the groundwater geochemistry in western Nile Delta area as an example of an aquifer influenced by reclamation and seawater intrusion. To conduct this study, 63 groundwater samples and one surface water sample from El Nubaria Canal were collected. To estimate the origin of dissolved ions and the geochemical processes influencing this groundwater, integration between land use change, pedological, hydrogeological, hydrogeochemical, and statistical approaches was considered. Results suggest that the groundwater flow regime changed from northeast and southwest directions around El Nubaria canal before 1966 to northern and northeastern directions due to newly constructed channel network. Soil salinity and mineral contents, seepage from irrigation canal, and seawater intrusion are the main factors controlling the groundwater chemistry. Statistically, the groundwater samples were classified into eight groups, one to four for the deep groundwater and five to eight for the shallow groundwater. The deep groundwater is characterized by two groups of chemicals (SO 4 -HCO 3 -Mg-Ca-K and Cl-Na), while the shallow groundwater groups of chemicals are Na-Cl-SO 4 and K-HCO 3 -Ca-Mg. Both shallow groundwater and deep groundwater are mostly saturated with respect to carbonate minerals and undersaturated with respect to chloride minerals. Sulfate minerals are above the saturation limit in the shallow groundwater, but in the deep samples, these minerals are under the saturation limit. Ion exchange, carbonate production, mineral precipitation, and seawater intrusion are the geochemical processes governing the groundwater chemistry in the study area.

    On 15 May 1939, John J. Lynch of the U.S. Bureau of Biological Survey located 13 whooping cranes (Grus americana), including 2 prefledged young, during an aerial survey near White Lake in southwestern Louisiana. His observation was the last historic record of whooping cranes breeding in the wild in the United States, and it confirmed the presence of a nonmigratory breeding population along the Gulf Coast. While reviewing old U.S. Fish and Wildlife Service files at the National Archives in 1999, we located Lynch's original 1939 field note, 2 letters, 5 photographs, and a draft manuscript describing the discovery; 4 other related letters also were found. Because of their biological and historical interest, we have reproduced the documents in this paper. A thorough assessment of the White Lake marshes as a potential site for returning nonmigratory whooping cranes to southwestern Louisiana should be conducted.

    This report presents recommendations relative to the use of expert systems and machine learning techniques by the Bureau of Labor Statistics (BLS) to substantially automate product substitution decisions associated with the Consumer Price Index (CPI). Thirteen commercially available, PC-based expert system shells have received in-depth evaluations. Various machine learning techniques were also reviewed. Two recommendations are given: (1) BLS should use the expert system shell LEVEL5 OBJECT and establish a software development methodology for expert systems; and (2) BLS should undertake a small study to evaluate the potential of machine learning techniques to create and maintain the approximately 350 ELI-specific knowledge bases to be used in CPI product substitution review.

    In his highly regarded and influential Modernity and the Holocaust Zygmunt Bauman launched one of the most passionate and sustained critiques of 'bureaucratic rationality' seen within social theory for some time. In so doing he drew heavily upon the work of Max Weber for support. In this brief paper I am interested in exploring the extent to which Weber really is the anti-bureaucratic ally Bauman claims him to be. In the first part of the paper I outline the main elements of Bauman's critique of bureaucratic rationality, drawing particular attention to its reliance upon a self-consciously Weberian theoretical lexicon. In the second part of the paper I seek to indicate that, despite his claims to be following in Weber's tracks, Bauman's conclusions regarding the moral vacuity of bureaucratic conduct are the very antithesis of Weber's own.

    The purpose of this study was to determine the comparative environmental impacts of coupled seawater desalination and water reclamation using a novel hybrid system that consist of an osmotically driven membrane process and established membrane desalination technologies. A comparative life cycle assessment methodology was used to differentiate between a novel hybrid process consisting of forward osmosis (FO) operated in osmotic dilution (ODN) mode and seawater reverse osmosis (SWRO), and two other processes: a stand alone conventional SWRO desalination system, and a combined SWRO and dual barrier impaired water purification system consisting of nanofiltration followed by reverse osmosis. Each process was evaluated using ten baseline impact categories. It was demonstrated that from a life cycle perspective two hurdles exist to further development of the ODN-SWRO process: module design of FO membranes and cleaning intensity of the FO membranes. System optimization analysis revealed that doubling FO membrane packing density, tripling FO membrane permeability, and optimizing system operation, all of which are technically feasible at the time of this publication, could reduce the environmental impact of the hybrid ODN-SWRO process compared to SWRO by more than 25%; yet, novel hybrid nanofiltration-RO treatment of seawater and wastewater can achieve almost similar levels of environmental impact.

    Full Text Available Prediction of tunneling induced soil deformation is an important issue in the design of tunnels constructed in the densely populated urban areas. In this paper, commercial FEM software 3D ABAQUS is adopted to simulate the behavior of soil caused by tunneling under vehicle loads in the coastal reclamation area. A field case study was also carried out to verify the accuracy of the proposed model. A good agreement was achieved. It is also found from the studies that the areas affected by soil deformation can be classified into four zones: the key disturbed zone, the secondary disturbed zone, the general disturbed zone, and minor-disturbed zone. The maximum soil deformation occurs on side of the longitudinal medial axis of the tunnel. The shape of the settlement curve is almost the same as that of the normal distribution curve. The soil deformation in the action zone of vehicle load is greater than that of the nonaction zone of vehicle load.

    Soil contaminated by hydrocarbons, cannot be used for agricultural intents due to their toxic effect to the plants. Surfactants producing by plant growth promotory rhizobacteria (PGPR) can effectively rig the problem of petroleum hydrocarbon contamination and growth promotion on such contaminated soils. In the present study three Pseudomonas strains isolated from contaminated soil identified by 16S rRNA analysis were ascertained for PGPR as well as biosurfactants property. Biosurfactants produced by the strains were further characterized and essayed for rhamnolipids. Inoculation of the strains in petrol hydrocarbon contaminated soil and its interaction with Withania somnifera in presence of petrol oil hydrocarbons depict that the strains helped in growth promotion of Withania somnifera in petrol oil contaminated soil while rhamnolipids helped in lowering the toxicity of petrol oil. The study was found to be beneficial as the growth and antioxidant activity of Withania sominfera was enhanced. Hence the present study signifies that rhamnolipids producing PGPR strains could be a better measure for reclamation of petrol contaminated sites for growing medicinal plants.

  20. Decoupling Agricultural Nonpoint Source Pollution from Crop Production: A Case Study of Heilongjiang Land Reclamation Area, China

    Full Text Available Modern agriculture often leads to nonpoint source pollution. From the perspective of a decoupling analysis, this research evaluates the relationship between crop production and agricultural nonpoint source pollution (via fertilizer application, using the Heilongjiang land reclamation area as a case study. As it is the largest commodity grain base and green food base in China, more than 80% of water pollution in this area comes from fertilizer application. This study adopts an export coefficient model to hindcast nitrogen loss delivered to surface water via fertilizer application and conduct a further analysis of decoupling agricultural nonpoint source pollution from crop production. The results indicated that weak decoupling frequently occurred. However, this tendency was not steady in the period 2001–2012, and weak decoupling was typical in each branch based on the average value. Regarding the example of decoupling agricultural nonpoint source pollution from rice production, weak decoupling occurred more often, but this tendency was not steady over time. In addition, expansive coupling occurred in 2006, 2010 and 2012, and there were no definite signs of it improving. All branches, except for the Suihua branch, reached the degree of weak decoupling. A basic fact is that a decoupling tendency and environmental deterioration coexist in both the past and present. The decoupling analysis will contribute to localized strategies for sustainable agricultural development.

    The Japan Nuclear Cycle Development Institute (JNC) conducted research and development projects on uranium exploration in Japan from 1956 to 1987. Several mine facilities, such as waste rock yards and a mill tailing pond, were retained around Ningyo-toge after the projects ended. Although there is no legal issue in the mine in accordance with related law and agreements at present, JNC has a notion that it is important to reduce the burden of waste management on future generations. Thus, the Ningyo-toge Environmental Engineering Center of JNC proposed a reclamation plan for these facilities with fundamental policy, an example of safety analysis and timetables. The plan has mainly three phases: Phase I is the planning stage, and this paper corresponds to this: Phase II is the stage to perform various tests for safety analysis and site designing: Phase III is the stage to accomplish measures. Preliminarily safety analyses suggested that our supposed cover designs for both waste rock and m ill tailing are enough to keep dose limit of 1mSv/y at site boundaries. The plan is primarily based on the Japanese Mine Safety Law, also refers to ICRP recommendations, IAEA reports, measures implemented overseas, etc. because this is the first case in Japan. For the accomplishment of this plan, it is important to establish a close relationship with local communities and governments, and to maintain a policy of open-to-public

  2. Vertical Distribution and Flux of Nutrients in the Sediments of the Mangrove Reclamation Region of Muara Angke Kapuk, Jakarta

    Full Text Available The reclaimed mangrove estuary in Muara Angke Kapuk is a reclaimed area that has not evaded the impacted of pollution and waste in the areas surrounding Cengkareng, Jakarta. This is apparent from the fact that almost all sediments under the mangrove trees are buried under heaps of plastic trash. However, the reclaimed region still has variety of organism, which indicating that the region still has an internal carrying capacity, especially nutrients from sediment. The purpose of this research was to examine the condition of sediment nutrients in this mangrove reclamation region. The research was conducted by taking water samples using a modification of the stratified cup at a sediment depth of 0-15 cm with depth intervals of 2.5 cm, and taking sediment samples using the sediment ring. Pore water samples were measured for dissolved oxygen (DO and concentrations of ammonia, nitrite, nitrate, and phosphate. Sediment samples were used to obtain porosity values. The data obtained is used to make vertical concentration profiles and analysis of vertical nutrient flux. Vertical nutrient flux analysis was performed with the aid of QUAL2K software version 2.11. The results showed different vertical distributions and flux of nutrients, where influx for ammonia and phosphate and an increase in line with increasing sediment depth, while nitrate efflux and a decreased concentration. The flux calculation of nitrite as transitory nutrient was not done, but the concentration decreased after a depth of 2.5 cm. This indicates that the high contamination on the surface does not prevent the natural chemical processes so the reclaimed region can still provide nutritional support for its organism.

    Intensive agricultural development can change land use, which can further affect regional ecosystem services and functions. With the rapid growth of the population and the national demand for food, the northeast of China, which is located in the high latitudes, has experienced four agricultural developments since the 1950s. The original wetlands of this area were developed for farmland. The evaluation of ecosystem services is conducted to reveal the ecosystem status and variable trends caused by land reclamation. The aim of this study is to provide scientific basis for environmental management and for the sustainable development of agriculture in Northeast China. With GIS-RS technology, a typical farm was chosen to analyze variations in the ecosystem service value in response to land use changes during the study period. The total ecosystem service value of the farm decreased from 7523.10 million Yuan in 1979 to 4023.59 million Yuan in 2009 with an annual rate of -1.6 % due to the decreasing areas of woodland and wetland. The increased areas of cropland, water area and grassland partly offset the loss of the total value, but the loss was still greater than the compensation. Waste treatment and climate regulation were the top two service functions with high service values, contributing to approximately 50 % of the total service value. The spatial difference of the ecosystem service value also was analyzed. The wetlands located in the central and northeastern sections of the farm changed significantly. From the aspect of ecosystem service value, the wetland and water area should be conserved, as they have the highest value coefficients. The accuracy of the value coefficient, however, needs to be studied further in future research.

    2016-07-26

    The use of forward osmosis (FO) is growing among the researchers for water desalination and wastewater treatment due to use of natural osmotic pressure of draw solute. In this study pressure assisted forward osmosis (PAFO) was used instead of FO to increase the water production rate. In this study a low concentration of draw solution (0.25 M KCl) was applied so that diluted KCl after PAFO operation can directly be used for fertigation. The performance of PAFO was investigated for the treatment of reverse osmosis concentrate (ROC) from a water reclamation plant. The water production in PAFO was increased by 9% and 29% at applied pressure of 2 and 4 bars, respectively, to feed side based on 90 h of experiments. Granular activated carbon (GAC) pretreatment and HCl softening were used to reduce organic fouling and scaling prior to application of PAFO. It reduced total organic carbon (TOC) and total inorganic carbon (TIC) by around 90% and 85%, respectively from untreated ROC. Subsequently, this led to an increase in permeate flux. In addition, GAC pretreatment adsorbed 12 out of 14 organic micropollutants tested from ROC to below detection limit. This application enabled to minimise the ROC volume with a sustainable operation and produced high quality and safe water for discharge or reuse. The draw solution (0.25 M KCl) used in this study was diluted to 0.14 M KCl, which is a suitable concentration (10 kg/m3) for fertigation, due to water transport from feed solution. © 2016 Elsevier B.V.

    By 1883 a Veterinary Division had been established within the United States Department of Agriculture, itself established in 1862. Federal concern about animal health in the U.S.A. emerged as early as 1865 when Congress adopted regulations aimed at controlling importation of livestock. It was not until 1884 that the Bureau of Animal Industry (BAI) was formally created by Act of Congress, and shortly after that the Zoological Laboratory was established and assigned responsibility for study of parasites and the diseases they produce in animals. Classically trained parasitologists working in USDA's BAI soon became internationally recognized for their contributions to basic research and development of programs for prevention and control of parasitic diseases. Leadership by a series of BAI-employed parasitologists led to the emergence of veterinary parasitology as a sub-discipline. Maurice C. Hall who served as president of both the American Society of Parasitologists and the American Veterinary Medical Association was a central figure in development of veterinary parasitology in the U.S.A., which flourished in his country and elsewhere today.

  15. The influence of arbuscular mycorrhizae on root precision nutrient foraging of two pioneer plant species during early reclamation

    On many post mining sites in the Lusatian Mining District (East Germany) soil heterogeneity consists of sandy soil with embedded clay-silt fragments. Those clays silt fragments might act as nutrient hotspots. Arbuscular mycorrhizal fungi in an infertile ecosystem could enhance a plant's ability to selectively forage for those nutrients and thus to improve plants nutrient supply. In our study we investigated whether silt-clay fragments within a sandy soil matrix induced preferential root growth of Lotus corniculatus and Calamagrostis epigeios, whether arbuscular mycorrhizae influenced root foraging patterns, and to what extent selective rooting in clay silt fragments influenced plant growth were addressed in this research. Soil types were sterile and non-sterile sandy soil and clay-silt fragments. Treatments were with and without arbuscular mycorrhizae, with and without soil solution, and soil solution and mycorrhizal inoculum combined. Root biomass, root density and intraradical fungal alkaline phosphatase activity and frequency were determined in fragments relative to sandy soil. Furthermore, temporal relationship of number of roots in fragments and plant height was assessed. Lotus corniculatus showed strong selective rooting into fragments especially with those plants treated with commercial cultivated arbuscular mycorrhizae; Calamagrostis epigeios did not. Without arbuscular mycorrhizae, L. corniculatus growth was significantly reduced and selective rooting did not occur. Selective rooting induced significant growth spurts of L. corniculatus. Roots in fragments had higher fungal alkaline phosphatase activity suggesting that mycorrhizal efficiency and related plants phosphorus supply is enhanced in roots in fragments. The application of cultivated arbuscular mycorrhizal fungi significantly and quickly influenced root foraging patterns, especially those of L. corniculatus, suggesting mycorrhizae may also enhance the ability of other plants to selectively forage
