Sample records for prevent water pollution

  1. Municipal water pollution prevention program

    International Nuclear Information System (INIS)

    1991-03-01

    EPA believes that the most effective and equitable means of assuring viability of this infrastructure is through environmentally preferred pollution prevention approaches especially through application of Municipal Water Pollution Prevention (MWPP). These approaches may enhance worker safety, improve the usability of sludge, increase the ability for local community expansion, and reduce operation and compliance costs. State-based municipal pollution prevention programs focus attention on a series of actions to prevent pollution in advance rather than taking more expensive corrective actions. MWPP encourages resource conservation to reduce water and energy use, appropriate pricing, toxicity reductions at the source, BOD reductions, recycling, proper treatment of wastes, and beneficial uses of sludge

  2. CONSTRUCTED WETLAND TECHNOLOGY TO PREVENT WATER RESOURCES POLLUTION

    Full Text Available Discharge of untreated waste waters into surface waters creates significant pollution in these resources. Wastewaters are most of the time discharged into seas, rivers and other water bodies without any treatments due to high treatment costs both in Turkey and throughout the world. Constructed wetlands, also called as natural treatment systems, are used as an alternative treatment system to conventional high-cost treatment systems because of their low construction, operation and maintenance costs, energy demands, easy operation and low sludge generation. Today, constructed wetland systems are largely used to treat domestic wastewaters, agricultural wastewaters, industrial wastewater and runoff waters and ultimately to prevent water pollution and to improve water quality of receiving water bodies. In present study, currently implemented practices in design, construction, operation and maintenance of constructed wetlands were assessed and potential mistakes made in different phases these systems were pointed out and possible solutions were proposed to overcome these problems.

  3. Drainage treatment technology for water pollution prevention

    1988-03-01

    Drainage is purified either at terminal treatment plants or by septic tanks for sewage. At terminal treatment plants, sewage is purified by activated sludge prosessing or by biological treatment equipment. By the normal activated sludge processing, only 20 - 30 % of nitrogen and phosphur can be removed. To solve this problem, many advanced processing systems have been employed, representative systems being coagulating sedimentation, rapid filtration, recirculating nitro-denitrification, etc. The coagulating sedimentation is a treatment process in which such metallic salt coagulations as aluminum, iron, etc. are injected and mixed with sewage, and then phosphur and the like are sedimented in the form of grains. The rapid filtration requires no large space, and can reliably remove suspended matter. For large scale septic tank processing system, advance treatment processing is supplemented to improve the quality of treated water. Among other systems of sewage purification are oxidized channel, oxidized pond, soil treatment, etc. (2 figs, 2 refs)

  4. Design an effective storm water pollution prevention plan

    A case history shows ''how'' to plan and organize a storm water pollution prevention program (SWPPP). Using easy-to-use worksheets and guidelines, hydrocarbon processing industry (HPI) operators can build upon existing best management practices (i.e., housekeeping procedures, visual inspections, spill prevention programs, etc.) to meet tighter restrictions set by National Pollutant Discharge Elimination system (NPDES) permits. Especially in high rainfall areas, storm water poses an intermittent, but large volume problem. The facility's site size is another factor that impacts the scope and cost for SWPPP. The five steps to implementing a SWPPP are: Planning and organization; Assessment; Best management practice (BMP) identification; Implementation; Evaluation and monitoring. Initially, HPI operators must identify all potential contamination sources and past spills and leak areas. Following the SWPP guidelines, operators can map out a cost-effective storm water program that meets all NPDES requirements

    Scotland was one of the world's first industrialised countries, and has therefore also been one of the first countries to experience wholesale post-industrial dereliction. Water pollution arising from abandoned mines, particularly abandoned coal mines, is second only to sewage as a source of freshwater pollution nation-wide, and in many coalfield catchments it is the pre-eminent source. Most of the pollution is due to net-alkaline ferruginous waters emerging from deep mines. Scrutiny of records from 80 deep mine discharges reveals that iron concentrations in these waters are only likely to exceed 20 mg/l, and the pH to be below 6.5, where the discharge emerges within 0.5 km of the outcrop of the shallowest mined seam. The bulk of mature near-outcrop mine water discharges in Scotland have<50 mg/l total Fe, and concentrations>100 mg/l are only likely where a marine bed lies within 25 m of the worked seam. Where the nearest marine bed is more than 80 m above or below the seam, then the total iron will be less than 4 mg/l, and in most cases less than 1 mg/l. Net-acidic mine waters are far more rare than net-alkaline waters in Scotland, and are most commonly associated with unreclaimed spoil heaps (bings). Both net-alkaline and net-acidic discharges have detrimental effects on the hydrochemistry and biological integrity of receiving waters. Scotland has recently pioneered the use of pre-emptive pump-and-treat solutions to prevent mine water pollution, and has also experienced the successful introduction of passive treatment technology for both abandoned and active workings.

    The report summarizes the surface water sampling program at the Amoco Refinery at Yorktown, Virginia. This was undertaken as a part of the joint project between Amoco Corporation and the United States Environmental Protection Agency to review pollution prevention alternatives at a petroleum refinery. The surface water data provides a snapshot of surface water pollutant generation and discharge from the refinery. Different process units contribute to the total wastewater flow of 460 GPM in the refinery. Water in the ditch system, which is non-process water, is free of organic contamination. Oil and grease, phenols, ammonia and sulfides are the significant components measured in the process wastewater. The concentrations of organics in most water streams leaving the individual process units are relatively low, in the 1-5 parts per million (ppm) range. A few individual streams such as the crude desalter brine and tank water draws have high pollutant loadings. Concentrations of metals in the refinery wastewater are very low. The wastewater treatment plant is very effective in reducing the pollutant loading in the water with overall removal efficiencies greater than 99% for most organics and inorganics

  16. Pollution prevention: A regulatory update

    International Nuclear Information System (INIS)

    Walzer, A.E.; Maynard, J.W.

    1993-01-01

    Pollution prevention is the emphasis of the 1990s environmental philosophy. This new environmental era was ushered in when President Bush signed the Pollution Prevention Act in October 1990. This law, with its accompanying philosophy, was in response to the realization that end-of-the-pipe treatment, which frequently changed the media in which a pollutant or waste was discharged, was inadequate to protect the environment and human health. Pollution prevention advocates source reduction, where material substitutions and engineering solutions are sought to reduce the volume and toxicity of waste and pollutants. This proactive approach reduces environmental impacts such as those of former waste sites which have produced environmental legacies that will cost billions of dollars and take decades to remediate. This paper describes pollution prevention philosophy and summarizes regulatory pollution prevention requirements. It describes current regulatory trends in the area of pollution prevention, including voluntary programs and enforcement actions. The Pollution Prevention Act of 1990 is described, and pollution prevention initiatives embodied in other laws, including the Clean Air Act, the Clean Water Act, the Emergency Planning and Community Right-To-Know Act, the Resource Conservation and Recovery Act, and the Toxic Substances Control Act, are discussed. A historical overview of waste minimization initiatives within the Department of Energy is given, and other pollution prevention initiatives that affect federal facilities, such as Executive Order 12780, which mandates recycling and the procurement of recycled materials, are also outlined

    This paper describes the progress and the major results of research and development on technologies and measures to prevent water pollution in China. Tests and researches have been performed on an upward anaerobic sludge blanket (UASB), a vertical baffled anaerobic sludge blanket, two-phase anaerobic digestion, and an anaerobic fluidized bed. When anaerobically digested sludge and aerobic active sludge are inoculated in the UASB, particle-shaped sludge was formed well in both sludges. This technology has begun to be used in breweries and citric acid factories. With anaerobic treatment of waste water containing sulfate, the sulfate was recovered as sulfur by using the first and second phases. Research and development is being progressed on the oxidation ditch technology as an improved version of the active sludge method. In a pilot test of a soil treatment system and a stabilization pond treatment system as alternative technology for the active sludge method, the BOD in the treated water was found 2.5 mg{times}1/l. Attentions are drawn on primary treatment, a living organism contact oxidation method, and a continuous filtration treatment process as technologies to turn polluted water into resources. 6 refs., 1 tab.

    To assess progress in pollution prevention, estimates or measurements of the amounts of pollution actually prevented have to be made. Such estimates or measurements tell us how far we have come and, possibly, how much farther there is to go in utilizing pollution prevention as a tool for improving environmental quality. They can, theoretically, be used to assess progress on a scale ranging from the individual facility or even the individual process or activity generation wastes to scale as large as a geographical area such as a county, a state or even the United States as a whole. 3 refs

    All across the US, facility managers and environmental staff are trying to keep up with proliferating regulations and associated filing and reporting requirements. Added to the already full plate of regulations is the National Pollutant Discharge Elimination System (NPDES) program for storm water management. The NPDES program requires a permit for the discharge of runoff from facilities based on Standard Industrial Classification (SIC) code. Some businesses do not yet need to comply with NPDES, as not all types of facilities were included in the Phase 1 list of regulated activities (September 1992). However, most businesses will be included as part of Phase 2 by 2002. Furthermore, states adopting administration of the NPDES program have the option of accelerating the process. In addition to filing for a permit, the NPDES storm water program requires the preparation and implementation of a Storm Water Pollution Prevention Plan (SWPPP). A properly prepared SWPPP can help facilities more easily comply with regulatory requirements and serve as an overall facility management tool.

    A Pollution Prevention/Waste Minimization Program was established during the early design phase of the U.S. DOE's New Production Reactor/Heavy Water Reactor Facility (NPR/HWRF) to encompass design, construction, operation and decommissioning. The primary emphasis of the program was given to waste elimination, source reduction and/or recycling to minimize the quantity and toxicity of material before it enters the waste stream for treatment or disposal. The paper discusses the regulatory and programmatic background as it applies to the NPR/HWRF and the waste assessment program developed as a phased approach to pollution prevention/waste minimization for the NPR/HWRF. Implementation of the program will be based on various factors including life cycle cost analysis, which will include costs associated with personnel, record keeping, transportation, pollution control equipment, treatment, storage, disposal, liability, compliance and oversight.

    2014-02-01

    Full Text Available The natural phenomenon of run-off and erosion lead to unpreventable pesticide water pollution in case of extreme weather conditions. In this relationship the use of herbicides involves a higher risk than other pesticides because of the specific terms of application. Directive 2009/128/EC for the sustainable use of pesticides aspires to enhanced water protection. German national action plan contains quantitative objectives which require strong reduction of water pollution by run-off and erosion of pesticides and accordingly herbicides. The European TOPPS prowadis project developed a consolidated and basic diagnosis concept for the first time to determine the field specific run-off risk. Compatible mitigation measures were linked to specific risk scenarios. Risk diagnosis and suitable mitigation measures determine best management practices for the prevention of run-off and erosion. Different new diagnosis methods and the implementation are presented. Further documents and information are available on the web [http://www.topps-life.org/].

    2005-01-01

    Oil spill pollution, a severe environmental problem, which persists in marine environment or in inland water across the world, has grown to an alarming magnitude with increased levels of oil production and transport. The causes oil pollution are categorized as either accidental or operational, wherever oil is produced, transported, stored and used on the surface of sea or land. Hence, it is almost impossible for marine life to be freed from the adverse affects of oil spill, through the discharge of oil is controlled by an international convention. Prime concern for the health of marine life has created an instinct for undertaking this study by authors. Objectives of the present work include testing of four different local materials in separating oil from having different oil concentrations, and their efficiency of removal. The work also focuses on effect of time of contact and dosage of materials used for oil removal. Corchorus depressus locally available has proved to be more effective when compared to other materials utilized in addressing oil-spill related problems. At the same time its byproducts do not give rise to unwanted hazards to marine life. (author)

    Full Text Available Methods: The present report attempts to illustrate the positive impact on the microbiological quality of dialysis patients over a 15-year period through the progressive implementation of state-of-the-art technological strategies and the optimization of microbiological surveillance procedures in five dialysis units in Sardinia. Results: Following on better microbiological, quality controls of dialysis water and improvement of procedures and equipment, a drastic improvement of microbiological water quality was observed in a total of 945 samples. The main aim was to introduce the use of microbiological culture methods as recommended by the most important guidelines. The microbiological results obtained have led to a progressive refining of controls and introduction of new materials and equipment, including two-stage osmosis and piping distribution rings featuring a greater capacity to prevent biofilm adhesion. The actions undertaken have resulted in unexpected quality improvements. Conclusions: Dialysis water should be viewed by the nephrologist as a medicinal product exerting a demonstrable positive impact on microinflammation in dialysis patients. A synergic effort between nephrologists and microbiologists undoubtedly constitutes the most effective means of preventing dialysis infections.

    Clark, G.E.

    1998-08-01

    Most shipyards have viable Best Management Practices (BMPs) in place to mitigate the transport of heavy metals to surface waters by storm water. Despite aggressive efforts to control storm water, shipyards have come under increased regulatory pressure to further reduce concentrations of heavy metals, such as copper and nickel, in storm water discharges. The tightening of regulatory requirements warrants research into additional BMPs. The objectives of this research project were to: (1) determine the feasibility of placing a replaceable cartridge of adsorbent material within a storm water collection system; and (2) evaluate two commercially available charred porous polymer adsorbents for the removal of heavy metals from storm water. The results indicated that there are commercially available storm water treatment components which could be adapted to house a cartridge of porous adsorbent material.

    1993-01-01

    The plutonium processing facility at Los Alamos has adopted the strategic goal of becoming a facility that processes plutonium in a way that produces only environmentally benign waste streams. Pollution prevention through source reduction and environmentally sound recycling are being pursued. General approaches to waste reductions are administrative controls, modification of process technologies, and additional waste polishing. Recycling of waste materials, such as spent acids and salts, are technical possibilities and are being pursued to accomplish additional waste reduction. Liquid waste stream polishing to remove final traces of plutonium and hazardous chemical constituents is accomplished through (a) process modifications, (b) use of alternative chemicals and sorbents for residue removal, (c) acid recycling, and (d) judicious use of a variety of waste polishing technologies. Technologies that show promise in waste minimization and pollution prevention are identified. Working toward this goal of pollution prevention is a worthwhile endeavor, not only for Los Alamos, but for the Nuclear Complex of the future

    Water is in constant circulation from the ocean to the earth's atmosphere and back to the ocean. In the course of this cycle, the composition of the water is altered by natural and human influences. Depending on the prevailing conditions, the water may contain solute gases, undissolved substances, inorganic salts, organic compounds, and microorganisms of varying types and concentrations. Many of these substances are known to pollute the water and thus to threaten its various uses. Emitting sources of water pollutants are: waste waters, seepings from open dumpings, mineral fertilizers and biocides washed out from agricultural areas, water pollutants emitted during storage and transport, air pollutants, and erosions from roads. The thermal load is an additional factor. Technical and legal steps are necessary in order to prevent water pollution and to maintain the quality of water required for its various uses. These measures are treated in detail. (orig./AK) [de

    This plan serves as the principal crosscutting guidance to Department of Energy (DOE) Headquarters, Operations Office, laboratory, and contractor management to fully implement pollution prevention programs within the DOE complex between now and 2000. To firmly demonstrate DOE's commitment to pollution prevention, the Secretary of Energy has established goals, to be achieved by December 31, 1999, that will aggressively reduce DOE's routine generation of radioactive, mixed, and hazardous wastes, and total releases and offsite transfers of toxic chemicals. The Secretary also has established sanitary waste reduction, recycling, and affirmative procurement goals. Site progress in meeting these goals will be reported annually to the Secretary in the Annual Report on Waste Generation and Waste Minimization Progress, using 1993 as the baseline year. Implementation of this plan will represent a major step toward reducing the environmental risks and costs associated with DOE operations

  10. Pollution prevention applications in batch manufacturing operations

    Sykes, Derek W.; O'Shaughnessy, James

    2004-02-01

    Older, "low-tech" batch manufacturing operations are often fertile grounds for gains resulting from pollution prevention techniques. This paper presents a pollution prevention technique utilized for wastewater discharge permit compliance purposes at a batch manufacturer of detergents, deodorants, and floor-care products. This manufacturer generated industrial wastewater as a result of equipment rinses required after each product batch changeover. After investing a significant amount of capital on end of pip-line wastewater treatment technology designed to address existing discharge limits, this manufacturer chose to investigate alternate, low-cost approaches to address anticipated new permit limits. Mass balances using spreadsheets and readily available formulation and production data were conducted on over 300 products to determine how each individual product contributed to the total wastewater pollutant load. These mass balances indicated that 22 products accounted for over 55% of the wastewater pollutant. Laboratory tests were conducted to determine whether these same products could accept their individual changeover rinse water as make-up water in formulations without sacrificing product quality. This changeover reuse technique was then implement at the plant scale for selected products. Significant reductions in wastewater volume (25%) and wastewater pollutant loading (85+%) were realized as a direct result of this approach.

    Available data were reviewed to assess the status of contamination by persistent organic pollutants (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs), perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), in drinking water sources and coastal waters of China. The levels of POPs in China's waters were generally at the high end of the global range. A comparison of China's regulatory limits indicated that PCBs in rivers and coastal water may pose potential human health risk. Occurrence of DDTs in some rivers of China may also pose health risk to humans using the regulatory limits of DDTs recommended by the European Union. Future monitoring of POPs in China's waters should be directed towards analytes of concern (e.g. PCBs and PCDD/Fs) and to fill data gaps for analytes (e.g. PBDEs, PCDD/Fs, and chlordane) and in watersheds/regions (e.g. West China) where data are scarce. - Highlights: ► Levels of POPs in China's aquatic systems were generally at the high end of the global range. ► New inputs of DDTs, likely related to the use of dicofol and anti-fouling paints, were found. ► Occurrence of PCBs and DDTs in some water bodies pay pose potential human health risk. ► Long-term monitoring of POPs in China's waters is needed to fill data gaps. - Occurrence, potential sources and ecological and human health risk of persistent organic pollutants in China's waters are reviewed.

    2008-01-01

    Full Text Available The government of the Czech Republic decided that in the location to the west of Prague, capital city of the Czech Republic, some deep mines should be closed because of their low efficiency of coal mined i.e. small amounts and low quality of the coal extracted in the final stage of mining. The locations near Prague influenced the decision to do maintenance on the abandoned mines, as the thread of soil pollution was unacceptably high in the neighborhood of the capital city. Before the mines were closed it was necessary to separate existed extensive horizontal location of salt water below a clay layer in order not to deteriorate the upper fresh water. The salt water could not be allowed to pollute the upper layer with the fresh water, as many wells in villages in the neighborhood of the former mines would be contaminated. Two horizontal clay layers (an insulator and a semi-insulator separated the two horizons containing salt water and fresh water. Before starting deep mining, vertical shafts had to be constructed with concrete linings to enable the miners to access the depths. The salt water was draining away throughout the existence of the mine. The drainage was designed very carefully to avoid possible infiltration of salt water into the upper horizon. Before the mines were abandoned it was necessary to prevent contact between the two kinds of waters in the shafts. Several options were put forward, the most efficient of which appeared to be one that proposed filling the shafts with spoil soil and creating a joint seal made of disparate material at the interface between the salt water and fresh water to create a reliable stopper. The material for the spoil soil was delivered from deposits located not far from the shafts. This material consisted of a variety of grains of sand, big boulders of slate, slaty clay, sandstone, etc.. Chemical admixtures were considered to improve the flocculation of the filling material. The stopper was positioned at a

    Water has played a very important role in the development of human society. Resources of water have shaped the development of people and nations. Management of water gave the birth to innovations and technologies. Our complex metropolitan civilization and advanced technologies have generated new demands for water. Its importance to society and government has never diminished. The growing concern over resources availability and a rapid spread of water pollution, the link between water supply and water quality have become more apparent. The global management of water demands economy in use, restricted chemical and sanitation emissions, population control, discouragement of urbanization and water pollution awareness can greatly assist in averting the water holocaust that the world is expecting to face in the years to come. The scientific community in Pakistan is required to diagnose these problems in a systematic way to give advance warning of expected water scarcity, water pollution, water related land degradation, urban growth and population to assure the water cycle integrity of our world.

  17. Pollution prevention constraints within DOE facilities

    International Nuclear Information System (INIS)

    Walzer, A.E.

    1992-01-01

    The signing of the Pollution Prevention Act of 1990, has marked a new environmental era. The 1990s environmental movement is shifting from ''end of the pipe'' treatment towards a philosophy of source reduction (predicated by the Pollution Prevention Act), where engineering solutions and materials substitution are sought to reduce the volume and toxicity of waste. This change comes after 20 years of treatment legislation, where in many cases the location or media in which our pollution is deposited was merely changed. This problem is exemplified by the enormous environmental problems created by waste sites. Our inability to deal with the substantial waste generated has produced the environmental legacy on the Department of Energy (DOE) sites, a legacy that will cost billions of dollars to remediate. How then do we solve our waste problems and avoid future legacies? This paper outlines some of the obstacles to pollution prevention within the DOE system and explores opportunities to remove these barriers. Industry, whose foundation is economics, has found it attractive to reduce their wastes, particularly in the wake of escalating waste disposal costs. However, within federal facilities where basic economic principles do not prevail, incentives towards pollution prevention need to be evaluated. Our current system of segregated DOE programs creates obstacles for waste generators to work productively with other programs. Certain policies and practices also limit the generators' responsibility and costs for their waste, which is counter productive to waste minimization and pollution prevention. To meet new environmental challenges and to be proactive in pollution prevention we must evaluate our systems and remove barriers that impede progress toward pollution prevention

    1995-12-01

    Pollution prevention is at the top of the waste management hierarchy in the United States. If you don`t create pollution in the first place, concerns about transportation, treatment, storage, and disposal of waste are moot. While industry is on the front line in accomplishing significant pollution prevention, universities can play a meaningful role in its accomplishment as well. Universities can do this through three basic missions: education, research, and public service. Examples of how this is carried out at the University of Tennessee, Knoxville are provided. To be fully effective, universities need to organize in an interdisciplinary manner and adopt a public outreach agenda.

    The US Department of Energy's (DOE's) Pollution Prevention Information Clearinghouse (EPIC) is a computer system intended for the exchange of pollution prevention information DOE-wide. EPIC is being developed as a distributed system that will allow access to other databases and applications. The first prototype of EPIC (Prototype I) was put on-line in January 1994. Prototype I contains information on EM-funded pollution prevention projects; relevant laws, regulations, guidance, and policy; facility and DOE contacts; and meetings and conferences. Prototype I also gives users access to the INEL Hazardous Solvent Substitution Data System (HSSDS) and to information contained on the US Environmental Protection Agency's (EPNS) Pollution Prevention Infbrmation Exchange System (PIES) as a test of the distributed system concept.

    2017-12-01

    Full Text Available Nowadays, wide applications of plastics result in plastic waste being present in the water environment in a wide variety of sizes. Plastic wastes are in water mainly as microplastics (the size range of 1 nm to < 5 mm. Microplastics have been recognized as an emerging threat, as well as ecotoxicological and ecological risk for water ecosystems. In this review are presented some of the physicochemical properties of plastic materials that determine their toxic effect on the aquatic environment. Wastewater treatment plants (WWTPs are mentioned as one of main sources of microplastics introduced into fresh water, and rivers are the pathways for the transportation of the pollutants to seas and oceans. But, effluents from tertiary wastewater treatment facilities can contain only minimally microplastic loads. The issue of discharge reduction of plastic pollutants into water environment needs activities in the scope of efficient wastewater treatment, waste disposal, recycling of plastic materials, education and public involvement.

    A bioaquatic air pollution control system for controlling both water and atmospheric pollution is disclosed. The pollution control system includes an exhaust for directing polluted gases out of a furnace and a fluid circulating system which circulates fluid, such as waste water, from a source, past the furnace where the fluid flow entrains the pollutants from the furnace. The combined fluid and pollutants are then directed through a rock/plant/microbial filtering system. A suction pump pumps the treated waste water from the filter system past the exhaust to again entrain more pollutants from the furnace where they are combined with the fluid (waste water) and directed to the filter system.

    This project investigated technologies that may reduce environmental pollution. This was a basic research/educational project addressing two major areas: A. In the algae research project, newly isolated strains of microalgae were investigated for feedstock production to address the production of renewable fuels. An existing collection of microalgae was screened for lipid composition to determine strains with superior composition of biofuel molecules. As many microalgae store triacylglycerides in so-called oil bodies, selected candidate strains identified from the first screen that accumulate oil bodies were selected for further biochemical analysis, because almost nothing was known about the biochemistry of these oil bodies. Understanding sequestration of triacylglycerides in intracellular storage compartments is essential to developing better strains for achieving high oil productivities by microalgae. At the onset of the project there was almost no information available on how to obtain detailed profiles of lipids from strains of microalgae. Our research developed analytical methods to determine the lipid profiles of novel microalgal strains. The project was embedded into other ongoing microalgal projects in the Polle laboratory. The project benefited the public, because students were trained in cell cultivation and in the operation of state-of-the-art analytical equipment. In addition, students at Brooklyn College were introduced into the concept of a systems biology approach to study algal biofuels production. B. A series of new nanostructured catalysts were synthesized, and characterized by a variety of physical and chemical methods. Our catalyst design leads to active nanostructures comprising small metal particles in intimate contact with strongly basic sites provided by the supports, which include poly(4-vinylpyridine), magnesium oxide, functionalized multi-walled carbon nanotubes, and graphene oxide. The new materials display a good potential as catalysts

  6. Smart City Environmental Pollution Prevention and Control Design Based on Internet of Things

    Science.gov (United States)

    Peng, He; Bohong, Zheng; Qinpei, Kuang

    2017-11-01

    Due to increasingly serious urban pollution, this paper proposes an environmental pollution prevention and control system in combination with Internet of things. The system transfers data through the Internet, which also utilizes sensor, pH sensor and smoke sensor to obtain environmental data. Besides, combined with the video data acquired through monitoring, the data are transferred to data center to analyze the haze pollution, water pollution and fire disaster in environment. According to the results, multi-purpose vehicles are mobilized to complete the tasks such as spraying water to relieve haze, water source purification and fire fighting in city environment. Experiments show that the environmental pollution prevention and control system designed in this paper can automatically complete the urban environmental pollution detection, prevention and control, which thus reduces human and material resources and improves the efficiency of pollution prevention and control. Therefore, it possesses greatly practical significance to the construction of smart city.

  7. The role of soil layers in preventing ground water pollution with 17ß-estradiol hormone (E 2

    Directory of Open Access Journals (Sweden)

    A’zam Golzari

    2016-03-01

    Full Text Available Background: Estrogens include estoril (E3, estradiol and estrone (E1. These chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs. Estrogens can enter water sources in different ways. When these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. Estrogens in wastewater are able to pass soil layers and contaminate groundwater. Therefore, in this study, the removal of the hormone 17ß-estradiol (E2 as a representative of estrogens in three types of soils was studied. The selection was chosen in respect to the importance of entering the hormone into groundwater through the soil. Methods: This study was an experimental study in which the removal of the hormone E2 from different depths of three types of soils was experimented. The soils were consisted of two different textures, the silty sandy clay and the silty sand with gravel. The hormone E2 was diluted and injected into the drilled holes. Soils were characterized in the soil mechanics laboratory. Hormone extraction from the soils was performed using a centrifuge and analyzed with the Elecsys device. The results were analyzed using the IBM SPSS version 22 software. Results: The results showed that the removal rates of hormone E2 in the three types of soils were higher than 99.5%, and the removal rate in the silty sand was more than the others. In all three soil samples, the removal rates in the first layer were high. The average injected hormone in the soil decreased from 3500 to 3112 ng/l. The results showed that the adhesion and plasticity of the soil had also affected the removal rates. Conclusion: Results showed that the soil plays a significant role in the removal of E2 hormone and this hormone was reduced or eliminated in the first layers of the soils. Thus, the risk of groundwater contamination is low.

  8. Pollution prevention and energy conservation: Understanding the interactions

    International Nuclear Information System (INIS)

    Purcell, A.H.

    1992-01-01

    The traditional view holds that pollution prevention is good for energy conservation and vice versa. Analysis of pollution prevention and energy conservation activities indicates, however, that interactions and synergies between environmental and energy factors can mean that pollution prevention can be energy intensive and, conversely, that energy conservation can lead to increased pollution. Full cost accounting, taking into account all media, must be performed before precise pollution prevention-energy conservation interrelationships can be characterized and quantified. Use of a pollution prevention-energy conservation matrix can further this understanding

    A safety installation for preventing pollution by pipelines, particularly those used for transporting liquid hydrocarbons, is described. It is applicable to any pipeline, but particularly to underground or submarine pipelines, whether made of steel, plastics, or any other material. The 4 essential objects of the invention are to insure reliable prevention of pollution of the environment due to leakage of a hydrocarbon through cracks in the pipe; to evacuate the leakage flow without delay to a vessel; to signal almost instantaneously the existence of a leak; and to effect remote control of operations by which the dynamic pressure in the pipe is cancelled. Each equipped section consists of a fluid-type jacket of plastic material which surrounds the pipe, which at its ends is sealed off. It is these seals which delimit the sections. (7 claims)

These goals and accompanying strategies are to be implemented by DOE sites through the integration of Pollution Prevention into each site's Environmental Management System (EMS). This document presents a P2 and Sustainability Program and corresponding plan pursuant to DOE Order 450.1 and DOE O 435.1, Radioactive Waste Management. This plan is also required by the state of Idaho, pursuant to the Resource Conservation and Recovery Act (RCRA) partial permit. The objective of this document is to describe the Idaho National Laboratory (INL) Site P2 and Sustainability Program. The purpose of the program is to decrease the environmental footprint of the INL Site while providing enhanced support of its mission. The success of the program is dependent on financial and management support. The signatures on the previous page indicate INL, ICP, and AMWTP Contractor management support and dedication to the program. P2 requirements have been integrated into working procedures to ensure an effective EMS as part of an Integrated Safety Management System (ISMS). This plan focuses on programmatic functions which include environmentally preferable procurement, sustainable design, P2 and Sustainability awareness, waste generation and reduction, source reduction and recycling, energy management, and pollution prevention opportunity assessments. The INL Site P2 and Sustainability Program is administratively

    This paper presents an innovative, quantitative assessment of pollution avoidance attributable to environmental regulation enforced through integrated licensing, using Ireland's pharmaceutical-manufacturing sector as a case study. Emissions data reported by pharmaceutical installations were aggregated into a pollution trend using an Environmental Emissions Index (EEI) based on Lifecycle Assessment methodologies. Complete sectoral emissions data from 2001 to 2007 were extrapolated back to 1995, based on available data. Production volume data were used to derive a sectoral production index, and determine 'no-improvement' emission trends, whilst questionnaire responses from 20 industry representatives were used to quantify the contribution of integrated licensing to emission avoidance relative to these trends. Between 2001 and 2007, there was a 40% absolute reduction in direct pollution from 27 core installations, and 45% pollution avoidance relative to hypothetical 'no-improvement' pollution. It was estimated that environmental regulation avoided 20% of 'no-improvement' pollution, in addition to 25% avoidance under business-as-usual. For specific emissions, avoidance ranged from 14% and 30 kt a(-1) for CO(2) to 88% and 598 t a(-1) for SO(x). Between 1995 and 2007, there was a 59% absolute reduction in direct pollution, and 76% pollution avoidance. Pollution avoidance was dominated by reductions in emissions of VOCs, SO(x) and NO(x) to air, and emissions of heavy metals to water. Pollution avoidance of 35% was attributed to integrated licensing, ranging from between 8% and 2.9 t a(-1) for phosphorus emissions to water to 49% and 3143 t a(-1) for SO(x) emissions to air. Environmental regulation enforced through integrated licensing has been the major driver of substantial pollution avoidance achieved by Ireland's pharmaceutical sector - through emission limit values associated with Best Available Techniques, emissions monitoring and reporting requirements, and

    The Pollution Prevention Opportunity Assessment (PPOA) is a pro- active way to look at a waste generating activity and identify opportunities to minimize wastes through a cost benefit analysis. Hanford`s PPOA process is based upon the graded approach developed by the Kansas City Plant. Hanford further streamlined the process while building in more flexibility for the individual users. One of the most challenging aspects for implementing the PPOA process at Hanford is one overall mission which is environmental restoration, Now that the facilities are no longer in production, each has a different non- routine activity making it difficult to quantify the inputs and outputs of the activity under consideration.

    2015-01-01

    The purpose of this paper is to discover the latent causal chain of industrial water pollution in China and find ways to cure the want on discharge of toxic waste from industries. It draws evidences from the past pollution incidents in China. Through further digging the back interests and relations by analyzing representative cases, extended theory about loophole derivations and causal chain effect is drawn. This theoretical breakthrough reflects deeper causality. Institutional defect instead of human error is confirmed as the deeper reason of frequent outbreaks of water pollution incidents in China. Ways for collaborative environmental governance are proposed. This paper contributes to a better understanding about the deep inducements of industrial water pollution in China, and, is meaningful for ensuring future prevention and mitigation of environmental pollution. It illuminates multiple dimensions for collaborative environmental governance to cure the stubborn problem.

    2015-01-01

    Agricultural decision-making to control nonpoint source (NPS) water pollution may not be efficiently implemented, if there is no appropriate cost-benefit analysis on agricultural management practices. This paper presents an interval-fuzzy linear programming (IFLP) model to deal with the trade-off between agricultural revenue, NPS pollution control, and alternative practices through land adjustment for Wuchuan catchment, a typical agricultural area in Jiulong River watershed, Fujian Province of China. From the results, the lower combination of practice 1, practice 2, practice 3, and practice 7 with the land area of 12.6, 5.2, 145.2, and 85.3 hm(2), respectively, could reduce NPS pollution load by 10%. The combination yields an income of 98,580 Chinese Yuan/a. If the pollution reduction is 15%, the higher combination need practice 1, practice 2, practice 3, practice 5, and practice 7 with the land area of 54.4, 23.6, 18.0, 6.3, and 85.3 hm(2), respectively. The income of this combination is 915,170 Chinese Yuan/a. The sensitivity analysis of IFLP indicates that the cost-effective practices are ranked as follows: practice 7 > practice 2 > practice 1 > practice 5 > practice 3 > practice 6 > practice 4. In addition, the uncertainties in the agriculture NPS pollution control system could be effectively quantified by the IFLP model. Furthermore, to accomplish a reasonable and applicable project of land-use adjustment, decision-makers could also integrate above solutions with their own experience and other information.

  16. Pollution prevention opportunity assessment: Foundation of pollution prevention for waste management

    International Nuclear Information System (INIS)

    Damewood, R.W.

    1994-01-01

    The objective of this paper is to promote the Pollution Prevention Opportunity Assessment (PPOA) technique as a fundamental of pollution prevention for waste management. All key elements of an effective PPOA program are presented. These key elements include impacts of environmental laws on pollution prevention, PPOA concepts and overview, waste minimization opportunities assessment, reporting and monitoring waste minimization progress, and PPOA program implementation. As environmental laws evolve the focus is shifting from end-of-pipe pollution control to front-end source reduction. Waste minimization was mistakenly interpreted to mean the reduction of hazardous waste after generation in the past. The Pollution Prevention Act of 1990 has clearly defined its requirement on resource reduction. Waste reduction can be viewed as a criterion to assess all industrial processes and operations. The fundamental approach of PPOA focuses on a mass balance concept. This concept deals with tracking of chemicals from the point of purchase, through storage, utilization in the process, and waste generation at the end of process. In other words, PPOA is a technique to analyze this input/output process. By applying PPOA techniques, the framework of applicable compliance requirements to the current operation process is established. Furthermore, documentation of PPOA itself can meet as documentation requirements for environmental compliance. In general, the PPOA process consists of two phases. The first phase involves input and output process description and waste characterization. The second phase is an opportunities assessment for waste minimization from input/output waste characterization. These two phases are explained in detail in the paper

  18. Organ nic pollutants in underground water

    International Nuclear Information System (INIS)

    Hussein, H. H.

    1998-01-01

    Many organic compounds have been diagnosed in underground and surface waters, and there are many theories that explain the source of the dangerous materials on Punic health. The source of pollution could be the underground stored fuel or the polluted water in farms saturated with agricultural insecticides and chemical fertilizers, or there could be leaks in sewage water wastes. The source of pollution could also be the water surfaces in the areas of garbage disposal or industrial and home waste discharge. Due to the fact that the underground water is separated from oxygen in the air, its ability on self-purification is very low, in that the micro-organism that will do the dismantling and decomposition of the organic materials that pollute the water are in need for oxygen. In the event that underground water is subject to pollution m there are many methods for t resting the polluted water including the chemical decomposition method by injecting the polluted areas with neutralizing or oxidizing chemicals, such as Ozone, Chlorine or Hydrogen Peroxide. The mechanical methods could be used for getting rid of the volatile organic materials. As to biological decomposition, it is done with the use of bacteria in dismantling the poisonous materials into un poisonous materials. The preliminary analysis of water samples in one of the water wells in Sar ir and Tazarbo in Great Jamahirieh indicated that the concentration of total organic compounds (TOC) exceeded the internationally allowed limits. This indicates a deterioration of quality of some of underground water resources. It is well known that some of the organic pollutants have a great role in causing dangerous diseases, such as the polynuclear aromatic hydrocarbons and some halogenated compounds that cause cancer. Therefore, much research is required in this field for diagnosing the polluting organic compounds and determining the suitability of this water for drinking or for human consumption.

  20. Water pollution control for underground coal gasification

    International Nuclear Information System (INIS)

    Humenick, M.J.

    1984-01-01

    Water pollution arising from underground gasification of coal is one of the important considerations in the eventual commercialization of the process. Because many coal seams which are amenable to in situ gasification are also ground-water aquifers, contaminants may be released to these ground waters during and after gasification. Also, when product gas is processed above ground for use, wastewater streams are generated which are too polluted to be discharged. The purpose of this paper is to characterize the nature of the groundwater and above-ground pollutants, discuss the potential long and short-term effects on ground water, propose control and restoration strategies, and to identify potential wastewater treatment schemes

  1. Air pollution prevention at the Hanford Site: Status and recommendations

    International Nuclear Information System (INIS)

    Engel, J.A.

    1995-08-01

    With the introduction of the Clean Air Act Amendments of 1990 and other air and pollution prevention regulations, there has been increased focus on both pollution prevention and air emissions at US DOE sites. The Pollution Prevention (P2) Group of WHC reviewed the status of air pollution prevention with the goal of making recommendations on how to address air emissions at Hanford through pollution prevention. Using the air emissions inventory from Hanford's Title V permit, the P2 Group was able to identify major and significant air sources. By reviewing the literature and benchmarking two other DOE Sites, two major activities were recommended to reduce air pollution and reduce costs at the Hanford Site. First, a pollution prevention opportunity assessment (P2OA) should be conducted on the significant painting sources in the Maintenance group and credit should be taken for reducing the burning of tumbleweeds, another significant source of air pollution. Since they are significant sources, reducing these emissions will reduce air emission fees, as well as have the potential to reduce material and labor costs, and increase worker safety. Second, a P2OA should be conducted on alternatives to the three coal-fired powerhouses (steam plants) on-site, including a significant costs analysis of alternatives. This analysis could be of significant value to other DOE sites. Overall, these two activities would reduce pollution, ease regulatory requirements and fees, save money, and help Hanford take a leadership role in air pollution prevention

    1993-01-01

    Following a short overview of hazard potentials for ground water in Germany, this book, which was compiled by the technical committee of DVWK on ground water use, discusses the natural scientific bases of pollutant movement to and in ground water. It points out whether and to what extent soil/ground water systems can be protected from harmful influences, and indicates relative strategies. Two zones are distinguished: the unsaturated zone, where local defence and remedial measures are frequently possible, and the saturated zone. From the protective function of geological systems, which is always pollutant-specific, criteria are derived for judging the systems generally, or at least regarding entire classes of pollutants. Finally, the impact of the infiltration of pollutants into ground water on its use as drinking water is pointed out and an estimate of the cost of remedial measures is given. (orig.) [de

    1994-01-01

    In support of the US Department of Energy`s (DOE`s) pollution prevention efforts being conducted under the aegis of DOE`s Office of Environmental Restoration and Waste Management (EM) program, Pacific Northwest Laboratory was tasked with evaluating pollution prevention information resources. The goal of this activity was to improve the effectiveness of DOE`s pollution prevention activities through improved information flow, both within the complex, and more specifically, between DOE and other organizations that share similar pollution prevention challenges. This report presents our findings with respect to the role of information collection and dissemination within the complex, opportunities for teaming from successes of the private sector, and specific information needs of the DOE pollution prevention community. These findings were derived from a series of interviews with pollution prevention coordinators from across the DOE complex, review of DOE site and facility pollution prevention plans, and workshops with DOE information users as well as an information resources workshop that brought together information specialists from private industry, non-profit organizations, as well as state and regional pollution prevention assistance programs.

  10. Application of environmental accounting to pollution prevention assessments

    International Nuclear Information System (INIS)

    Del Mar, R.A.

    1997-08-01

    Environmental accounting represents a major paradigm shift in the way most companies account for costs and benefits. However, it is a change that must be made if pollution prevention is to become institutionalized into the corporate and government mainstream. Pollution prevention investments must be justified on an economic basis; without environmental accounting tools, pollution prevention investments cannot show their true profitability. This is because traditional accounting methods only track billable costs, thus ignoring some of the major benefits of pollution prevention investments, which are indirect savings resulting from a lessening of a company's regulatory compliance burden and present and future liabilities. This paper discusses how to apply environmental accounting principles to pollution prevention assessments to improve the outcome of profitability analyses

  11. D and D TECHNOLOGIES FOR POLLUTION PREVENTION

    International Nuclear Information System (INIS)

    Tripp, Julia L.

    2003-01-01

    A new Accelerated Site Technology Deployment (ASTD) project was awarded in FY 2002 to the Idaho National Engineering and Environmental Laboratory (INEEL) to deploy technologies that decrease pollution and waste in the areas of facility characterization, sludge treatment, dust and contamination control, and concrete demolition. This project was called ''D and D Technologies for Pollution Prevention'' and planned to deploy four different technologies. To reduce protective equipment requirements, waste generation, and risk of radiation exposure during facility characterization, the Russian Gamma Locater Device (GLD) and Isotopic Identification Device (IID) for remote characterization was investigated. The GLD detects gamma ray readings and video images remotely and uses radio communication to transmit the readings to personnel located a safe distance from the contaminated area. The IID, an integral part of the GLD, provides real-time spectrometric analysis of radiation sources for remotely identifying the specific radioactive isotopes present in the facility. At the INEEL, sludge has accumulated in the bottom of a fuel storage pool and the presence of heavy metals in the sludge makes it a mixed waste. This project planned to use LEADX(reg s ign) to treat sludge in place to effectively make all heavy metals in the sludge insoluble. LEADX(reg s ign) is a dry granular chemical additive (apatite) used for in-situ treatment of heavy-metal-contaminated material. LEADX(reg s ign) chemically bonds to any free heavy metals that it contacts and forms a stable, non-leachable molecule. After treating the sludge with LEADX(reg s ign), it was to be left in the basin and the pool filled with grout. The successful treatment of the sludge with LEADX(reg s ign) will reduce the amount of waste to be disposed at the burial ground by eliminating the need to remove the sludge from the basin. Many off-gas and duct systems being dismantled contain dust and lint that has been contaminated

    US EPA is initiating a pollution prevention approach to supplement its historic command-control, regulatory approach to environmental protection. EPA believes polllution prevention, where applicable and possible, represents a quicker, less expensive and even profitable strategy for environmental protection. Most clearly, energy-efficiency provides an opportunity to prevent significant amounts of pollution related to the inefficeint generation and use of electricity. EPA's first energy productivity and pollution prevention program is Green Lights. Beyond its own merits, Green Lights will also provide important experience to EPA as it develops its Green Machines program to accelerate the market for efficient appliances and equipment

    International Nuclear Information System (INIS)

    Bockelmann, D.

    1994-01-01

    Alternatively to biological, physical and chemical methods of waste water cleaning, photocatalysis can be employed. In this residue-free method, titanium dioxide particles are brought into contact with polluted water as photocatalysts. Under UV irradiation at wave-lengths below 400 nm, change carriers are generated in the semiconductor particles that act so intensely oxidizing as to completely degrade almost all organic pollutants in waste water. In this process, the ultra-violet part of the solar spectrum can be harnessed to generate oxidation equivalents. Thus, solar photocatalytic waste water cleaning is excellently suited for developing countries. (BWI) [de

    Applying and developing constructive environment protection measures offers real and long lasting solutions that consolidate our future. In this context the Diving Center contribution in preventing radioactive pollution is enrolled. Our Center performed high quality services with authorised personal. Using their rich human, technological and scientific resources, the armed forces in general and our unity in this case, plays already an important role in supporting the development and natural environment, but results could be even greater and of high impact if the military and civilian requirements would be aligned, valorizing the qualified resources belonging to the military. The environment protection measures are an essential component of the sustainable development, which correctly and duly applied may provide a necessary and realistic option in the eternal confrontation between human activity and correct exploitation of environment. During pressure tests performed over years at the nuclear reactor from Cernavoda, the divers provided: - pressure test at Unit 1 reactor containment (test performed at a pressure of 128 kPa) in order to evaluate the loss rate; - solving previous problems of the sealing system of reactor containment and tracks of electrical cables, pipes, etc; - providing safety procedures for the Cernavoda NPP specialised personnel, after their entering the working area through the small transfer gate; - technical assistance and first aid in case of diving accidents, using the bi-place chamber (fitted with medication transfer sass) provided on site; - supervising the enforcement of legal procedures concerning training, organising and work protection in diving activities; - in case of a collective decompression accident, we had the responsibility to provide necessary treatment of personnel affected in the hyperbaric laboratory. All these activities, even though developed for specific military requirements, may satisfy the saving and protecting needs

    Godfrey, S.D.

    1998-01-01

    This paper presents several innovative and common sense approaches to pollution prevention that have been employed during facility deactivation at the Hanford Site in South Central Washington. It also presents several pollution prevention principles applicable to other projects. Innovative pollution prevention ideas employed at the Hanford site during facility deactivation included: (1) Recycling more than 185,000 gallons of radioactively contaminated nitric acid by sending it to an operating nuclear fuels reprocessing facility in England; (2) Recycling millions of pounds of chemicals and excess materials to other industries for reuse; (3) Evaporating flush water at a low rate and discharging it into the facility exhaust air stream to avoid discharging thousands of gallons of liquid to the soil column; and (4) Decontaminating and disposing of thousands of gallons of radioactively contaminated organic solvent waste to a RCRA licensed, power-producing, commercial incinerator. Common sense pollution prevention ideas that were employed include recycling office furniture, recycling paper from office files, and redeploying tools and miscellaneous process equipment. Additional pollution prevention occurred as the facility liquid and gaseous discharge streams were deactivated. From the facilities deactivation experiences at Hanford and the ensuing efforts to disposition excess chemicals and materials, several key pollution prevention principles should be considered at other projects and facilities, especially during the operational periods of the facility's mission. These principles include: Institute pollution prevention as a fundamental requirement early in the planning stage of a project or during the operational phase of a facility's mission; Promote recognition and implementation of pollution prevention initiatives; Instill pollution prevention as a value in all participants in the project or facility work scope; Minimize the amount of chemical products and materials

    Pollution prevention and adoption of clean technologies in the industry are to be the proper strategies to flight against the growing industrial pollution in Pakistan. These strategies will not only reduce the existing pollution load and will also help to have sustainable industrial development in Pakistan in is well established that the concept of pollution prevention demands use of minimum, resources with maximum efficiency to achieve double benefits such as resource conservation and environmental protection. The application of cleaner production and waste minimization in thousand of industries in other part of world has proved beyond doubt that the use of cleaner technology is cheaper as compared to installation of waste treatment plants for end of pipe treatment. Waste treatment plants have been blamed not to solve any pollution problem, but only to transfer pollution from one environmental media to another. The adoption of waste treatment technologies have also created lot of other problems. Thousand of industries in the world have change their focus of activities from end of pipe treatment to pollution prevention techniques. It is the right time to start pollution prevention activities in industry. The design of a product system in the industry can be represented logically as a series of decision and choices made individually and collectively by design participant. The choices range from the selection of materials and manufacturing processes to choices relating to shape, from and function of a product. The product life cycle design provides a logical system for addressing pollution prevention because the full range of environmental consequence associated with the product can be considered and it is a powerful tool for identifying and maximizing the environmental benefits of pollution prevention. The life cycle assesment (LCA) concept suggests that decision making should be based on consideration of the cradle-to grave characteristics of the product, process

    The purpose of the Pollution Prevention Awareness Program (PPAP), which is required by DOE Order 5400.1, is to foster the philosophy that prevention is superior to remediation. The goal of the program is to incorporate pollution prevention into the decision-making process at every level throughout the organization. The objectives are to instill awareness, disseminate information, provide training and rewards for identifying the true source or cause of wastes, and encourage employee participation in solving environmental issues and preventing pollution. PPAP at the Oak Ridge Y-12 Plant was created several years ago and continues to grow. We believe that we have implemented several unique methods of communicating environmental awareness to promote a more active work force in identifying ways of reducing pollution.

    Environmental problems in coal mining industry is increased with the demand of good quality of coal through coal washing/beneficiation activities. The coal washeries in general have been identified as one of the serious sources of water pollution particularly of Damodar river. Coal washeries though are designed on close water circuit, most of these however, fail to operate on close water circuit thus resulting in enormous quantity of effluents containing coal fines as well. This apart from posing serious water pollution problem also results into economic losses. The present study attempts to provide an insight into water pollution profile from coal washeries in Jharia coalfield. Various process parameters/unit operations in coal washing are also described. Effluents from various selected coal washeries of Jharia coalfield are sampled and analysed over a period of six months during 1993. Suspended solids, oil and grease and COD in the washery effluents are identified as the three major water quality parameters causing lots of concern for Damodar river pollution. Reasons for unavoidable discharge of effluents containing coal fines are also described. (author). 14 refs., 4 tabs., 2 figs

  7. Pollution Prevention Successes Database (P2SDb) user guide

    International Nuclear Information System (INIS)

    1995-07-01

    When Pollution Prevention Opportunity Assessments (P2OAs) were launched at the Hanford Site during the summer of 1994, the first comment received from those using them expressed the desire for a method to report assessments electronically. As a temporary measure, macros were developed for use on word processing systems, but a more formal database was obviously needed. Additionally, increased DOE and Washington state reporting requirements for pollution prevention suggested that a database system would streamline the reporting process. The Pollution Prevention Group of Westinghouse Hanford Company (WHC) contracted with the Data Automation Engineering Department from ICF Kaiser Hanford Company (ICFKH) to develop the system. The scope was to develop a database that will track P2OAs conducted by the facilities and contractors at the Hanford Site. It will also track pollution prevention accomplishments that are not the result of P2OAs and document a portion of the Process Waste Assessments conducted in the past. To accommodate the above criteria, yet complete the system in a timely manner, the Pollution Prevention Successes Database (P2SDb) is being implemented in three phases. The first phase will automate the worksheets to provide both input and output of the data associated with the worksheets. The second phase will automate standard summary reports and ad hoc reports. The third phase will provide automated searching of the database to facilitate the sharing of pollution prevention experiences among various users. This User's Guide addresses only the Phase 1 system

    Two complexes of lakes and canals supplying water for two electric power plants, their steam condensors and an adjoining river were investigated by means of culture methods for the presence of Naegleria fowleri in Poland in the period from 1974 to 1980. Sixty-four strains of N. fowleri were isolated, 13 isolates being virulent for mice when instilled intranasally. These strains were found in the steam condensor of the power station A and in waters polluted with warm water of this plant. Pathogenic N. fowleri strains occurred also in an adjoining river connected with the water system of the power plant. The results show the possible role of the steam condensor A as an incubator and regular source of pollution with pathogenic amoebae for its own system of cooling waters and even the adjoining river.

    Full Text Available Water pollution is one of the most serious environmental issues facing China. In 2005, an exceptionally serious water pollution accident in the Songhua River — caused by an unintended and sudden chemicals explosion — heralded an official recognition of a water pollution crisis in China. Although there have been new initiatives in national law and policy concerning water pollution that attempt to respond to issues of: social conflict caused by water pollution; government accountability; liability of polluting entities; and citizens’ rights in cases of water pollution, the challenges for the rule of environmental law in effectively reducing water pollution accidents and resolving water pollution conflict still exist. There is an urgent need to strengthen compliance and enforcement. This paper discusses the issues of water pollution conflict and the possible resolutions offered through law and policy.

    Full Text Available Currently, one of Mexico’s most severe environmental problems is the high levels of pollution of many of its rivers. The present article focuses on the relationship between total coliform bacteria levels and the increase of human digestive tract diseases in the highly polluted Atoyac River in the central Mexican states of Puebla and Tlaxcala. Pollution has become a potential health hazard for people living in nearby river communities. Based on data collected from six of the most contaminated riverside municipalities, two environmental models were developed taking into consideration the health of the entire population, not simply that of its individual members. Such models estimate a health-disease function that confirm the link between Atoyac River pollution and the incidence of gastrointestinal diseases. The causal relation between pollution and gastrointestinal disease incentivizes the creation of epidemiological and public health programs aimed at reducing the environmental health impact of the pollution associated with the Atoyac River. The results presented here are the first of their kind of this river and will serve as basis for future research exploring other similarly contaminated riparian communities. As the causes of pollution are directly related to the economic development and population growth of the region, further research should be conducted for prevention of diseases, educational programs, water remediation and conservation programs that will have a positive impact on the quality of life of the population presently at risk.

  15. Pollution prevention at ports: clearing the air

    International Nuclear Information System (INIS)

    Bailey, Diane; Solomon, Gina

    2004-01-01

    Seaports are major hubs of economic activity and of environmental pollution in coastal urban areas. Due to increasing global trade, transport of goods through ports has been steadily increasing and will likely continue to increase in the future. Evaluating air pollution impacts of ports requires consideration of numerous sources, including marine vessels, trucks, locomotives, and off-road equipment used for moving cargo. The air quality impacts of ports are significant, with particularly large emissions of diesel exhaust, particulate matter, and nitrogen oxides. The health effects of these air pollutants to residents of local communities include asthma, other respiratory diseases, cardiovascular disease, lung cancer, and premature mortality. In children, there are links with asthma, bronchitis, missed school days, and emergency room visits. The significance of these environmental health impacts requires aggressive efforts to mitigate the problem. Approaches to mitigation encompass a range of possibilities from currently available, low-cost approaches, to more significant investments for cleaner air. Examples of the former include restrictions on truck idling and the use of low-sulfur diesel fuel; the latter includes shore-side power for docked ships, and alternative fuels. A precautionary approach to port-related air pollution would encourage local production of goods in order to reduce marine traffic, greener design for new terminals, and state-of-the art approaches to emissions-control that have been successfully demonstrated at ports throughout the world

    1991-01-01

    Oil or other polluting material on or near the surface of a body of water is treated by a device comprising a tube having a slot through which fluid within the tube emerges. A cover directs the emerging fluid over the curved outer surface of the tube. The fluid may be water or a mixture of water and a dispersant. The device may be provided with fins. Some or all of the treated water may be collected in a tank and some or all may be returned to the sea. The device may be rendered buoyant by a pair of floats or may be part of a larger sea-going vessel. (Author)

    Wang, L; Wang, B

    2000-01-01

    The pollution of water resources and drinking water sources in China is described in this paper with basic data. About 90% of surface waters and over 60% of drinking water sources in urban areas have been polluted to different extents. The main pollutants present in drinking water sources are organic substances, ammonia nitrogen, phenols, pesticides and pathogenic micro-organisms, some of which cannot be removed effectively by the traditional water treatment processes like coagulation, sedimentation, filtration and chlorination, and the product water usually does not meet Chinese national drinking water standards, when polluted source water is treated. In some drinking-water plants in China, advanced treatment processes including activated carbon filtration and adsorption, ozonation, biological activated carbon and membrane separation have been employed for further treatment of the filtrate from a traditional treatment system producing unqualified drinking water, to make final product water meet the WHO guidelines and some developed countries' standards, as well as the Chinese national standards for drinking water. Some case studies of advanced water treatment plants are described in this paper as well.

    Moynihan, Gary P.

    2004-02-01

    Pollution prevention is a complex task. Many small foundries lack the in-house expertise to perform these tasks. Expert systems are a type of computer information system that incorporates artificial intelligence. As noted in the literature, they provide a means of automating specialized expertise. This approach may be further leveraged by implementing the expert system on the internet (or world-wide web). This will allow distribution of the expertise to a variety of geographically-dispersed foundries. The purpose of this research is to develop a prototype web-based expert system to support pollution prevention for the foundry industry. The prototype system identifies potential emissions for a specified process, and also provides recommendations for the prevention of these contaminants. The system is viewed as an initial step toward assisting the foundry industry in better meeting government pollution regulations, as well as improving operating efficiencies within these companies.

    The purpose of this presentation is to relay the experience of the Office of New Production Reactors (NP) in developing and implementing its pollution prevention program. NP was established to plan, design, and construct a new safe and environmentally acceptable nuclear reactor capacity necessary to provide an assured supply of tritium to maintain the nation`s long-term deterrent capability. The Program offered the Department of Energy an opportunity to demonstrate its commitment to environmental protection via minimization of environmental releases; new design offers the best opportunity for pollution prevention. The NP pollution prevention program was never fully implemented because NP`s tritium production design activity was recovery terminated. The information in this paper represented lessons learned from the last three years of NP operation.

    Ground-water at many Danish locations has been polluted by organic substances. This pollution has taken place in relation to leaks or spills of, for example, petrol from leaky tanks or oil separators. The article describes a new biological technique for the purification of ground-water polluted by petrol and diesel oils leaked at a petrol station. The technique involves decompostion by bacteria. During decompostion the biomass in the filter increases and carbon dioxide and water is produced, so there is no waste product from this process. The two units consist of an oil-separator which separates the diesel oil and petrol from the water, and a bio-filter which is constructed as an aired-through inverted filter to which nutrient salts are continually added. The filter-material used is in the form of plastic rings on which the oil-decomposing bacteria grow and reproduce themselves. The system is further described. It is claimed that the bio-filter can decompose 7 kg of petrol and diesel oil in one week, larger ones decompose more. The servicelife of the system is expected to be 4-6 years. Current installation costs are 20.000 - 100.000 Danish kroner, according to size. (AB)

    The North American Free Trade Agreement/North American Agreement on Environmental Cooperation provides a mechanism for an international collaboration between the US, Canada, and Mexico to jointly develop, modify, or refine technologies that remediate or protect the environment. These countries have a vested interest in this type of collaboration because contaminants do not respect the boundaries of a manufacturing site, region, city, state, or country. The Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL) consists of a diverse group of individuals who address a variety of environmental issues. ESD is involved in basic and applied research on the fate, transport, and remediation of contaminants; environmental assessment; environmental engineering; and demonstrations of advanced remediation technologies. The remediation and protection of the environment includes water, air, and soils for organic, inorganic, and radioactive contaminants. In addition to remediating contaminated sites, research also focuses on life-cycle analyses of industrial processes and the production of green technologies. The author focuses this discussion on subsurface remediation and pollution prevention; however, the research activities encompass water, soil and air and many of the technologies are applicable to all environments. The discussion focuses on the integration of biotechnology with remediation activities and subsequently linking these biological processes to other remediation technologies

  11. New technological methods for protecting underground waters from agricultural pollution

    The agricultural production on the irrigated grounds can not carry on without mineral fertilizers, pesticides and herbicides. Especially it is shown in Uzbekistan, in cultivation of cotton. There is an increase in mineralization, rigidity, quantity of heavy metals, phenols and other pollutions in the cotton fields. Thus there is an exhaustion of stocks of fresh underground waters. In the year 2003 we were offered to create the ecological board to prevent pollution to get up to a level of subsoil waters in the top 30 centimeter layer of the ground. We carried out an accumulation and pollution processing. This layer possesses a high adsorbing ability for heavy metals, mineral oil, mineral fertilizers remnants, defoliants and pesticides. In order to remediate a biological pollution treatment processing should be take into account. The idea is consisted in the following. The adsorption properties of coal is all well-known that the Angren coal washing factories in Tashkent area have collected more than 10 million tons of the coal dust to mix with clays. We have picked up association of anaerobic microorganisms which, using for development, destroys nutrients of coal waste pollutions to a harmless content for people. Coal waste inoculation also are scattered by these microorganisms on the field before plowing. Deep (up to 30 cm) plowing brings them on depth from 5 up to 30 cm. Is created by a plough a layer with necessary protective properties. The norm of entering depends on the structure of ground and the intensity of pollutions. Laboratory experiments have shown that 50% of pollutions can be treated by the ecological board and are processed up to safe limit.

    A marine environmental research programme is in course of carrying out for some years in a definite coastal zone of the southern Tirrenian Sea in order to point out possible significant pollutions, identify their origin and study the appropriate preventive and protective measures. In the first stage of the programme the analysis of the actual water quality was done, by evaluation of several indicators (temperature, conductivity, pH, turbidity and suspended sediments, dissolved oxygen, chlorophyll a, nutrients concentration, bacteriological parameters) at three different distances from the shore: 50 m, 500 m and 1 mile. The analysis of the collected values shows that the actual water quality is on the whole quite satisfactory, except for some restricted areas in which a bacteriological pollution, due to high concentrations of coliforms and Streptococcus faecalis, has been pointed out

    Abstract: Using the concept of life cycle analysis, the whole life cycle of anthracite production in Vietnam was assessed and the environmental 'hot-spots' were identified. These include (I) dust pollution at coal transfer points or piles in storage; (ii) noise pollution resulting from the usage of heavy equipment, and (iii) high volume of acid and turbid mine water discharged into the environment. Pollution prevention and treatment options were identified and discussed in this study which consists of wet treatment of dust, planning, collection and treatment of mine water, planting of trees for dust and noise reduction as well as minimization of erosion. Some recommendations are made for pollution abatement from coal production and improvement of anthracite production in the region.

  15. Radiation treatment of polluted water and wastewater

    International Nuclear Information System (INIS)

    2008-09-01

    Strategies to tackle environmental pollution have been receiving increasing attention throughout the world in recent years. Radiation processing using electron beam accelerators and gamma irradiators has shown very promising results in this area. Radiation processing in wastewater treatment is an additive-free process that uses the short lived reactive species formed during the radiolysis of water for efficient decomposition of pollutants therein. The rapid growth of the global population, together with the increased development of agriculture and industry, have led to the generation of large quantities of polluted industrial and municipal wastewater. The recognition that these polluted waters may pose a serious threat to humans has led technologists to look for cost effective technologies for their treatment. A variety of methods based on biological, chemical, photochemical and electrochemical processes are being explored for decomposing the chemical and biological contaminants present in the wastewaters. Studies in recent years have demonstrated the effectiveness of ionizing radiation such as, gamma rays and electron beams or in combination with other treatments, in the decomposition of refractory organic compounds in aqueous solutions and in the effective removal or inactivation of various microorganisms and parasites. The application of electron beam processing for drinking water, wastewater and groundwater treatment offers the promise of a cost effective process. The installation of the first full scale electron beam plant in Daegu, Republic of Korea, to treat 10 000 m 3 day -1 textile wastewater has demonstrated that the process is a cost effective technology when compared to conventional treatment. The regular operation of this facility provides operational data on reliability and additional data for a detailed economic evaluation. The IAEA has been supporting activities in this area by organizing advisory group meetings, consultants meetings, symposia and

    Full Text Available The aim of this study is to find out the kind of hydromacrophyte composition having the highest capability to reduce nitrate-phosphate pollutant and Microcystis growth in phytoremediation media using Equisetum ramosissium, Typha angustifolia and the combination of both. Microcystis were obtained from Sutami reservoir, then being inoculated in a media grown by hydromacrophytes (E. ramosissium, T. angustifolia and both of the hydromacrophytes in the batch culture system. The number of Microcystis was counted every day within fifteen days. Abiotic factors were observe, including the concentration of nitrate using brucine-colorimetry method and orthophosphate (dissolved phosphate using stannous chloride-colorimetry method on day 0, 6th, 12th and 15th. The growth rate of Microcystis carrying capacity and orthophosphate-nitrate levels among treatments were analysed by ANOVA test. The results showed that E. ramosissium and T. angustifolia in mono and polyculture techniques had similar potentiality to reduce the nitrate and ortophosphate. The concentrations of nitrate and orthophosphate decreased over 70 % in the 6th day after incubation. All of the treatments were able to reduce the carrying capacity of Microcystis up to 46 % , but the growth rates were similar in all media, that is, around 97-170 cells/L/day.

    Subterranean waters are often polluted by industrial and anthropic effluents that are drained in subsoil. To prevent and control pollution, legislations of different developed countries require an online monitoring measurement, especially for detecting organic solvents (chlorinated and unchlorinated ones). Online measurements include both real-time and no real-time measurements. In general, it is difficult to implement real-time measurements in stricto sensu for online acquisitions on aqueous effluents since they need to be processed by a modeling. This research presents an experimental measurement system based on infrared (IR) spectroscopy for aqueous effluents containing hydrocarbons and capable of displaying excellent values of pollutant concentrations even in instable conditions; the system is able to detect pollutants either in laminar or turbulent flow. The results show the possibility of avoiding the use of "Pitot tube" that is employed to create a stagnation point in order to convert kinetic energy into potential one. This conversion allows the transformation of a turbulent flow in a laminar flow making easy measurement of pollutants included in an aqueous effluent. Obviously, "Pitot tube" is also used for other fluid effluents. The obtained results have been compared with those produced by means of sophisticated IR instrumentation for laboratory applications.

    1997-01-01

    The Environmental Restoration (ER) Project at Sandia National Laboratories implicitly subscribed to the philosophy of pollution prevention and waste minimization. As a result of a Department of Energy (DOE) offer, Pollution Prevention Opportunity Assessments (PPOA) were conducted at two ER sites and a decontamination and Demolition (D and D) site. The purpose of one of the PPOAs was to identify pollution prevention (P2) opportunities during environmental remediation at the Classified Waste Landfill located at Sandia National Laboratories, New Mexico (SNL/NM). The remediation activities at this site are scheduled to begin in the fall of 1997. The PPOA included presentations by the team members, a tour of the site, and a brainstorming session to list the waste streams, identify P2 opportunities and rank them in order of priority. Twenty-five P2 opportunities were identified during the brainstorming session of which twenty-two opportunities were selected for further investigation. Those twenty-two opportunities are discussed in this paper. A cost benefit analysis was performed for each P2 opportunity based on the estimated waste volume, feasibility, and cost. Pollution Prevention by Design (P2D) was incorporated into the PPOA to introduce waste minimization techniques that can be used during the planning phase of restoration projects

    This Good Practice Guide provides tools, information, and examples for promoting the implementation of pollution prevention during the design phases of U.S. Department of Energy (DOE) projects. It is one of several Guides for implementing DOE Order 430.1, Life-cycle Asset Management. DOE Order 430.1 provides requirements for DOE, in partnership with its contractors, to plan, acquire, operate, maintain, and dispose of physical assets. The goals of designing for pollution prevention are to minimize raw material consumption, energy consumption, waste generation, health and safety impacts, and ecological degradation over the entire life of the facility (EPA 1993a). Users of this Guide will learn to translate national policy and regulatory requirements for pollution prevention into action at the project level. The Guide was written to be applicable to all DOE projects, regardless of project size or design phase. Users are expected to interpret the Guide for their individual project's circumstances, applying a graded approach so that the effort is consistent with the anticipated waste generation and resource consumption of the physical asset. This Guide employs a combination of pollution prevention opportunity assessment (PPOA) methods and design for environment (DfE) philosophies. The PPOA process was primarily developed for existing products, processes, and facilities. The PPOA process has been modified in this Guide to address the circumstances of the DOE design process as delineated in DOE Order 430.1 and its associated Good Practice Guides. This modified form of the PPOA is termed the Pollution Prevention Design Assessment (P2DA). Information on current nationwide methods and successes in designing for the environment also have been reviewed and are integrated into this guidance.

  2. Water Quality Protection from Nutrient Pollution: Case ...

    Science.gov (United States)

    Water bodies and coastal areas around the world are threatened by increases in upstream sediment and nutrient loads, which influence drinking water sources, aquatic species, and other ecologic functions and services of streams, lakes, and coastal water bodies. For example, increased nutrient fluxes from the Mississippi River Basin have been linked to increased occurrences of seasonal hypoxia in northern Gulf of Mexico. Lake Erie is another example where in the summer of 2014 nutrients, nutrients, particularly phosphorus, washed from fertilized farms, cattle feedlots, and leaky septic systems; caused a severe algae bloom, much of it poisonous; and resulted in the loss of drinking water for a half-million residents. Our current management strategies for point and non-point source nutrient loadings need to be improved to protect and meet the expected increased future demands of water for consumption, recreation, and ecological integrity. This presentation introduces management practices being implemented and their effectiveness in reducing nutrient loss from agricultural fields, a case analysis of nutrient pollution of the Grand Lake St. Marys and possible remedies, and ongoing work on watershed modeling to improve our understanding on nutrient loss and water quality.

  4. Waste Minimization/Pollution Prevention Crosscut Plan, 1994

    International Nuclear Information System (INIS)

    1994-01-01

    This plan establishes a Department-wide goal to reduce total releases of toxic chemicals to the environment and off-site transfers of such toxic chemicals by 50 percent by December 31, 1999, in compliance with Executive Order 12856. Each site that meets the threshold quantities of toxic chemicals established in the Emergency Planning and Community Right-to-Know Act (EPCRA) will participate in this goal. In addition, each DOE site will establish site-specific goals to reduce generation of hazardous, radioactive, radioactive mixed, and sanitary wastes and pollutants, as applicable. Implementation of this plan will represent a major step toward the environmental risks and costs associated with DOE operations and increasing the Department's use of preventive environmental management practices. Investing in Waste Minimization Pollution Prevention (WMin/PP) steadily reduce hazardous and radioactive waste generation and will reduce the need for waste management and unnecessary expenditures for waste treatment, storage, and disposal. A preventive approach to waste management will help solve current environmental and regulatory issues and reduce the need for costly future corrective actions. The purpose of this plan is to establish the strategic framework for integrating WMin/PP into all DOE internal activities. This program includes setting DOE policy and goals for reducing the generation of wastes and pollutants, increasing recycling activities, and establishing an infrastructure to achieve and measure the goals throughout the DOE complex. Waste Minimization and Pollution Prevention Awareness Plans, submitted to Headquarters by DOE field sites, will incorporate the WMin/PP activities and goals outlined in this plan. Success of the DOE WMin/PP program is dependent upon each field operation becoming accountable for resources used, wastes and pollutants generated, and wastes recycled

    1996-09-01

    This Report summarizes the waste generation and pollution prevention activities of the major operational sites in the Department of Energy (DOE). We are witnessing progress in waste reduction from routine operations that are the focus of Department-wide reduction goals set by the Secretary on May 3,1996. The goals require that by the end of 1999, we reduce, recycle, reuse, and otherwise avoid waste generation to achieve a 50 percent reduction over 1993 levels. This Report provides the first measure of our progress in waste reduction and recycling against our 1993 waste generation baseline. While we see progress in reducing waste from our normal operations, we must begin to focus attention on waste generated by cleanup and facilities stabilization activities that are the major functions of the Office of Environmental Management. Reducing the generation of waste is one of the seven principles that I have established for the Office of Environmental Management Ten Year Plan. As part of our vision to complete a major portion of the environmental cleanup at DOE sites over the next ten years, we must utilize the potential of the pollution prevention program to reduce the cost of our cleanup program. We have included the Secretarial goals as part of the performance measures for the Ten Year Plan, and we are committed to implementing pollution prevention ideas. Through the efforts of both Federal and contractor employees, our pollution prevention program has reduced waste and the cost of our operations. I applaud their efforts and look forward to reporting further waste reduction progress in the next annual update of this Report.

  13. Pollution prevention opportunity assessment benchmarking: Recommendations for Hanford

    Energy Technology Data Exchange (ETDEWEB)

    Engel, J.A.

    1994-05-01

    Pollution Prevention Opportunity Assessments (P2OAs) are an important first step in any pollution prevention program. While P2OAs have been and are being conducted at Hanford, there exists no standard guidance, training, tracking, or systematic approach to identifying and addressing the most important waste streams. The purpose of this paper then is to serve as a guide to the Pollution Prevention group at Westinghouse Hanford in developing and implementing P2OAs at Hanford. By searching the literature and benchmarks other sites and agencies, the best elements from those programs can be incorporated and pitfalls more easily avoided. This search began with the 1988 document that introduces P2OAs (then called Process Waste Assessments, PWAS) by the Environmental Protection Agency. This important document presented the basic framework of P20A features which appeared in almost all later programs. Major Department of Energy programs were also examined, with particular attention to the Defense Programs P20A method of a graded approach, as presented at the Kansas City Plant. The graded approach is a system of conducting P2OAs of varying levels of detail depending on the size and importance of the waste stream. Finally, private industry programs were examined briefly. While all the benchmarked programs had excellent features, it was determined that the size and mission of Hanford precluded lifting any one program for use. Thus, a series of recommendations were made, based on the literature review, in order to begin an extensive program of P2OAs at Hanford. These recommendations are in the areas of: facility Pollution Prevention teams, P20A scope and methodology, guidance documents, training for facilities (and management), technical and informational support, tracking and measuring success, and incentives.

  17. Regulatory barriers to pollution prevention: A position paper of the implementation council of the American institute for pollution prevention

    International Nuclear Information System (INIS)

    Byers, R.L.

    1991-01-01

    Pollution prevention/waste minimization is a win-win-win situation for government, industry, and the public, which offers more than just protection of the environment for all. Industry gains from reduced capital and operating costs, reduced liabilities, cleaner and safer working conditions, conservation of energy and material resources, and the opportunity for government and industry to work together in a cooperative manner. However, a number of regulatory barriers exist which discourage pollution prevention/waste minimization. This paper provides examples for the aluminum, chemical, petroleum, and wood treating industries of how these regulatory barriers become disincentives. To promote pollusion prevention/waste minimization, Congress and the US EPA need to reexamine those RCRA provisions which support a command and control strategy that creates the barriers. The barriers include the distinction between value and valueless materials, offsite storage requirements prior to reuse/recycle, the Derived from Rule, the Burning for Fuel Rule, land ban technology standards, and RD and D restrictions. A new RCRA Pollution Prevention/Waste Minimization subtitle is proposed to eliminate or minimize these barriers

  18. A new technology for harnessing the dye polluted water and dye collection in the chemical factory

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A new technology for harnessing the dye polluted water and dyecollection was developed. It is based on the enhanced evaporation by using solar, wind, and air temperature energy and additional heat-electric energy. It consists of four parts: (1) evaporation carrier system (evaporation carrier and frame for evaporation carrier) for polluted water; (2) polluted water circulating system (pumping-spraying-collecting); (3) heating system; (4) workshop with polluted water reservoir-tanks and rainfall prevention roof. The polluted water was (heated in case necessary) sprayed to the evaporation carrier system and the water was evaporated when it moved in the space and downward along the carrier mainly by using natural (solar, wind, and air temperature energy). In case, when there is no roof for the carrier system, thepolluted water can be stored in the reservoirs (storage volume for about 20 days). The first 10-25 mm rainfall also need to be stored in the reservoirs to meet the state standard for discharging wastewater. The dye may be collected at the surface in the reservoir-tanks and the crystallized salt may be collected at the bottom plate. The black-color wastewater released by the factory is no more discharged to the surface water system of Taihu Lake Basin. About 2 kg dye and 200 kg industrial salt may be collected from each tone of the polluted water. The non-pollution production of dye may be realized by using this technology with environmental, economical and social benefits.

  19. Recent developments in the DOE Waste Minimization Pollution Prevention Program

    Hancock, J.K.

    1993-01-01

    The U.S. Department of Energy (DOE) is involved in a wide variety of research and development, remediation, and production activities at more than 100 sites throughout the United States. The wastes generated cover a diverse spectrum of sanitary, hazardous, and radioactive waste streams, including typical office environments, power generation facilities, laboratories, remediation sites, production facilities, and defense facilities. The DOE's initial waste minimization activities pre-date the Pollution Prevention Act of 1990 and focused on the defense program. Little emphasis was placed on nonproduction activities. In 1991 the Office of Waste Management Operations developed the Waste Minimization Division with the intention of coordinating and expanding the waste minimization pollution prevention approach to the entire complex. The diverse nature of DOE activities has led to several unique problems in addressing the needs of waste minimization and pollution prevention. The first problem is developing a program that addresses the geographical and institutional hurdles that exist; the second is developing a monitoring and reporting mechanism that one can use to assess the overall performance of the program

    2017-01-01

    Full Text Available Water pollution detection is of great importance in water conservation. In this paper, the water pollution detection problems of the network and of the node in sensor networks are discussed. The detection problems in both cases of the distribution of the monitoring noise being normal and nonnormal are considered. The pollution detection problems are analyzed based on hypothesis testing theory firstly; then, the specific detection algorithms are given. Finally, two implementation examples are given to illustrate how the proposed detection methods are used in the water pollution detection in sensor networks and prove the effectiveness of the proposed detection methods.

    Danjiangkou Reservoir is the source reservoir of the Middle Route of the South-to-North Water Diversion Project (MRP). Any sudden water pollution accident in the reservoir would threaten the water supply of the MRP. We established a 3-D hydrodynamic and water quality model for the Danjiangkou Reservoir, and proposed scientific suggestions on the prevention and emergency management for sudden water pollution accidents based on simulated results. Simulations were performed on 20 hypothetical pollutant discharge locations and 3 assumed amounts, in order to model the effect of pollutant spreading under different reservoir operation types. The results showed that both the location and mass of pollution affected water quality; however, different reservoir operation types had little effect. Five joint regulation scenarios, which altered the hydrodynamic processes of water conveyance for the Danjiangkou and Taocha dams, were considered for controlling pollution dispersion. The results showed that the spread of a pollutant could be effectively controlled through the joint regulation of the two dams and that the collaborative operation of the Danjiangkou and Taocha dams is critical for ensuring the security of water quality along the MRP.

    The National Center for Manufacturing Sciences (NCMS) is sponsoring an on-going project to assess pollution prevention and control technology available to the plating industry and to make this information available to those who can benefit from it. Completed project activities include extensive surveys of the plating industry and vendors of technologies and an indepth literature review. The plating industry survey was performed in cooperation with the National Association of Metal Finishers. The contractor that conducted the surveys and prepared the project products was CAI Engineering. The initial products of the project were made available in April, 1994. These products include an extensive report that presents the results of the surveys and literature review and an electronic database. The project results are useful for all those associated with pollution prevention and control in the plating industry. The results show which treatment, recovery and bath maintenance technologies have been most successful for different plating processes and the costs for purchasing and operating these technologies. The project results also cover trends in chemical substitution, the identification of compliance-problem pollutants, sludge generation rates, off-site sludge recovery and disposal options, and many other pertinent topics.

  12. Prosperity without pollution: The prevention strategy for industry and consumers

    Hirschhorn, J.S.; Oldenburg, K.V.

    1990-01-01

    Here is the first book to explain why only a preventative environmental strategy can work: because growing population, consumption and industrialization cripple current, rather haphazard, remedial efforts. This book shows how our society can make more with less, be more competitive and less polluting, while maintaining our standard of living by reducing and eventually eliminating the production of wastes and pollutants from industry, commerce, homes, farms, and institutions. This may seem far-fetched, but be prepared to discover in this book that there can be a middle ground between ecology and economy - and that you can help achieve it. You'll find data and examples that any person can use, from engineers in industry to office workers to activists. Every concerned citizen will also want to consider the authors' innovative suggestions for taxing wastes and using the proceeds to help companies and communities switch to new industrial processes. Also, you should evaluate their proposals to reburies meaningful waste and toxicity information on product labels, to make bans on chemicals and products a more credible and available corrective measure, and to secure permanent, high-level government support for pollution prevention

    The Taoge water system is located in the upstream of Taihu Lake basin and is characterized by its multi-connected rivers and lakes. In this paper, current analyses of hydrology, hydrodynamics and water pollution of Gehu Lake and Taige Canal are presented. Several technologies are proposed for pollution prevention and control, and water environmental protection in the Taihu Lake basin. These included water pollution control integration technology for the water systems of Gehu Lake, Taige Canal and Caoqiao River. Additionally, river-lake water quality and quantity regulation technology, ecological restoration technology for polluted and degraded water bodies, and water environmental integration management and optimization strategies were also examined. The main objectives of these strategies are to: (a) improve environmental quality of relative water bodies, prevent pollutants from entering Gehu Lake and Taige Canal, and ensure that the clean water after the pre-treatment through Gehu Lake is not polluted before entering the Taihu Lake through Taige Canal; (b) stably and efficiently intercept and decrease the pollution load entering the lake through enhancing the river outlet ecological system structure function and water self-purifying capacity, and (c) designate Gehu Lake as a regulation system for water quality and water quantity in the Taoge water system and thus guarantee the improvement of the water quality of the inflow into Taihu Lake.

    The pollution prevention principle has become the dominant environmental-policy guideline in the Federal Republic of Germany and in the European Communities. The compatibility of the pollution prevention principle with the dominating ecological-economics theory is analyzed, and the differences between the pollution prevention and the polluter principle as a significant, economically founded guideline are defined on the basis of the results obtained. The implementation of the pollution prevention principle, which is understood as an extensive ecologization of the socio-economic structures, is discussed evaluating the contribution of normative and empirical ethics and investigating three closely related aspects, i.e. the development of a pollution prevention target system, the suitability of environmental-policy instruments with regard to different levels of prevention, and the national and democratic institutional prerequisites. The prospects of the pollution prevention principle within the European Communities are discussed on the basis of these findings. (orig.).

    1994-08-01

    This report tracks progress against the goals stated in the Hanford Site 5-year Pollution Prevention Plan. The executive summary of the plan was submitted to the Washington State Department of Ecology (Ecology) in September 1992. The plan, executive summary, and the progress reports are elements of a pollution prevention planning program that is required by Washington Administrative Code (WAC) 173-307 for all hazardous substance users and/or all hazardous waste generators regulated by Ecology. These regulations implement Chapter 70.95C, Revised Code of Washington, an act relating to hazardous waste reduction. The act encourages voluntary efforts to redesign industrial processes to help reduce or eliminate hazardous substances and hazardous waste byproducts, and to maximize the inprocess reuse or reclamation of valuable spent material. Although the Hanford Site is exempt, it is voluntarily complying with this state regulatory-mandated program. This is the first year the Hanford Site is submitting a progress report. It covers calendar year 1993 plus the last quarter of 1992. What is reported, in accordance with WAC 173-307, are reductions in hazardous substance use and hazardous waste generated. A system of Process Waste Assessments (PWA) was chosen to meet the requirements of the program. The PWAs were organized by a physical facility or company organization. Each waste-generating facility/organization performed PWAs to identify, screen, and analyze their own reduction options. Each completed PWA identified any number of reduction opportunities, that are listed individually in the plan and summarized by category in the executive summary. These opportunities were to be implemented or evaluated further over the duration of the 5-year plan. The basis of this progress report is to track action taken on these PWA reduction opportunities in relationship to achieving the goals stated in the Pollution Prevention Plan.

    This plan documents Westinghouse Hanford Company's (WHC) Pollution Prevention (P2) (formerly Waste Minimization) program. The program includes WHC; BCS Richland, Inc. (BCSR); and ICF Kaiser Hanford Company (ICF KH). The plan specifies P2 program activities and schedules for implementing the Hanford Site Waste Minimization and Pollution Prevention Awareness (WMin/P2) Program Plan requirements (DOE 1994a). It is intended to satisfy the U.S. Department of Energy (DOE) and other legal requirements that are discussed in both the Hanford Site WMin/P2 plan and paragraph C of this plan. As such, the Pollution Prevention Awareness Program required by DOE Order 5400.1 (DOE 1988) is included in the WHC P2 program. WHC, BCSR, and ICF KH are committed to implementing an effective P2 program as identified in the Hanford Site WMin/P2 Plan. This plan provides specific information on how the WHC P2 program will develop and implement the goals, activities, and budget needed to accomplish this. The emphasis has been to provide detailed planning of the WHC P2 program activities over the next 3 years. The plan will guide the development and implementation of the program. The plan also provides background information on past program activities. Because the plan contains greater detail than in the past, activity scope and implementation schedules may change as new priorities are identified and new approaches are developed and realized. Some activities will be accelerated, others may be delayed; however, all of the general program elements identified in this plan and contractor requirements identified in the Site WMin/P2 plan will be developed and implemented during the next 3 years. This plan applies to all WHC, BCSR, and ICF KH organizations and subcontractors. It will be distributed to those with defined responsibilities in this plan; and the policy, goals, objectives, and strategy of the program will be communicated to all WHC, BCSR, and ICF KH employees

    Full Text Available China’s socioeconomic transitions have dramatically accelerated its economic growth in last three decades, but also companioned with continuous environmental degradation. This study will advance the knowledge of heavy metal water pollution in China from a spatial–temporal perspective. Specifically, this study addressed the following: (1 spatial patterns of heavy metal water pollution levels were analyzed using data of prefecture-level cities from 2004 to 2011; and (2 spatial statistical methods were used to examine the underlying socioeconomic and physical factors behind water pollution including socioeconomic transitions (industrialization, urbanization, globalization and economic development, and environmental characteristic (natural resources, hydrology and vegetation coverage. The results show that only Cr pollution levels increased over the years. The individual pollution levels of the other four heavy metals, As, Cd, Hg, and Pb, declined. High heavy metal water pollution levels are closely associated with both anthropogenic activities and physical environments, in particular abundant mineral resources and industrialization prosperity. On the other hand, economic development and urbanization play important roles in controlling water pollution problems. The analytical findings will provide valuable information for policy-makers to initiate and adjust protocols and strategies for protecting water sources and controlling water pollution; thus improving the quality of living environments.

    A remote sensing application for the control of oil pollution and water quality was developed by the National Council of Research at Florence, and the University of Catania, both in Italy. The application is based on the simultaneous use of active antipassive remote sensing systems (lidar and flir systems) from a helicopter. Water pollution characteristics were determined with the lidar system, in polluted areas of water detected, on a larger scale, by the flir system. Pollution characteristics detected included type of pollutant, type of oil, and oil thickness. The experiment, named LIRA, was carried out using an Italian Navy helicopter over sea areas around Sicily having a high risk of pollution. The results proved the effectiveness and usefulness of the techniques proposed

    Water is an important component of the earth. Human being and living organisms are demand for the quality of water. Human activity is one of the causes of the water pollution. The pollution happened give bad effect to the physical and characteristic of water contents. It is not practical to monitor all aspects of water flow and transport distribution. So, in order to help people to access to the polluted area, a prediction of water pollution concentration must be modelled. This study proposed a one-dimensional advection diffusion equation for predicting the water pollution concentration transport. The numerical modelling will be produced in order to predict the transportation of water pollution concentration. In order to approximate the advection diffusion equation, the implicit Crank Nicolson is used. For the purpose of the simulation, the boundary condition and initial condition, the spatial steps and time steps as well as the approximations of the advection diffusion equation have been encoded. The results of one dimensional advection diffusion equation have successfully been used to predict the transportation of water pollution concentration by manipulating the velocity and diffusion parameters.

    It will not be easy to obtain a permit to open a new industrial plant. And not only the new ones but all important operating industrial productions will require a so called integrated permit. Both authorities and company managers consider the validation process to be more demanding compared to the current procedure for obtaining a building or user permit. As of August 1, 2003 - the day a new Act on Integrated Pollution Prevention and Control (IPPC) is expected to enter into force - only integrated permits will be given. The related bill has been passed to the parliament for the second reading. As of end of April next year the future of 31 industrial plants will depend on whether they will be granted a integrated permit or not. IPPC is a terror for companies due to its seriousness, complexity and the relatively short time given, should they not manage to obtain a permit the plant may be closed down. The European Commission (EC) Directive 96/61/EC Integrated Pollution Prevention and Control raises the same concerns among companies in European Union (EU) member states. It is one of the most strict environmental standards and one of the sensitive conditions of EU entry. That is one of the reasons transition periods for this Directive were negotiated for ten Slovak companies. (Authors)

    This seventh Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 45 reporting sites from 1993 through 1998. This section summarizes Calendar Year 1998 Complex-wide waste generation and pollution prevention accomplishments. More detailed information follows this section in the body of the Report. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive, mixed, and hazardous waste generation, to be achieved by December31, 1999. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1998 waste generation to the 1993 baseline. Excluding sanitary waste, routine operations waste generation decreased 67 percent overall from 1993 to 1998. However, for the first time since 1994, the total amount of materials recycled by the Complex decreased from 109,600 metric tons in 1997 to 92,800 metric tons in 1998. This decrease is attributed to the fact that in 1997, several large ''one-time only'' recycling projects were conducted throughout the Complex. In order to demonstrate commitment to DOE's Complex-wide recycling goal, it is important for sites to identify all potential large-scale recycling/reuse opportunities.

    Watershed water environment pollution model is the important tool for studying watershed environmental problems. Through the quantitative description of the complicated pollution processes of whole watershed system and its parts, the model can identify the main sources and migration pathways of pollutants, estimate the pollutant loadings, and evaluate their impacts on water environment, providing a basis for watershed planning and management. This paper reviewed the watershed water environment models widely applied at home and abroad, with the focuses on the models of pollutants loading (GWLF and PLOAD), water quality of received water bodies (QUAL2E and WASP), and the watershed models integrated pollutant loadings and water quality (HSPF, SWAT, AGNPS, AnnAGNPS, and SWMM), and introduced the structures, principles, and main characteristics as well as the limitations in practical applications of these models. The other models of water quality (CE-QUAL-W2, EFDC, and AQUATOX) and watershed models (GLEAMS and MIKE SHE) were also briefly introduced. Through the case analysis on the applications of single model and integrated models, the development trend and application prospect of the watershed water environment pollution models were discussed.

    The negative health effects of water pollution remain a major source of morbidity and mortality in China. The Chinese government is making great efforts to strengthen water environment treatment; however, no studies have evaluated the effects of water treatment on human health by water pollution in China. This study evaluated the association between water pollution and health outcomes, and determined the extent to which environmental regulations on water pollution may lead to health benefits. Data were extracted from the 2011 and 2013 China Health and Retirement Longitudinal Study (CHARLS). Random effects model and random effects Logit model were applied to study the relationship between health and water pollution, while a Mediator model was used to estimate the effects of environmental water treatment on health outcomes by the intensity of water pollution. Unsurprisingly, water pollution was negatively associated with health outcomes, and the common pollutants in industrial wastewater had differential impacts on health outcomes. The effects were stronger for low-income respondents. Water environment treatment led to improved health outcomes among Chinese people. Reduced water pollution mediated the associations between water environment treatment and health outcomes. The results of this study offer compelling evidence to support treatment of water pollution in China. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available In the State of Israel, advanced legislation for the management of scarce water resources, including legislation to prevent water pollution, were put in place in the early stages of the State’s formation. Despite that, on-going uncontrolled pollution has deteriorated the quality of water sources for decades, with the main source of pollution being untreated or partially treated domestic wastewater. This has been mainly the result of lack of enforcement of the existing laws. During the 1990s and onwards, a shift to forceful enforcement has been observed and wastewater treatment substantially improved. The paper analyzes the implementation processes of the pollution control legislations (the lack-of and the shift to forceful enforcement based on an actor-centered approach, using the contextual interaction theory.

    The following article is a literature review that summarizes results from field studies devoted to chemical analysis of water in Lebanon. Agricultural practices and the use of fertilizers may affect surface waters, ground water and drinking water. Much attention has been given to their environmental consequences, especially those related to water pollution by Nitrates and human health. The Nitrate content should not exceed in drinking water more than 50 mg/l for adults and 25 mg/l for children and pregnant women. Studies suggest incorporation of quick remedial measures to combat pollution in marine environments

  19. Anisotropic diffusion of volatile pollutants at air-water interface

    2013-04-01

    Full Text Available The volatile pollutants that spill into natural waters cause water pollution. Air pollution arises from the water pollution because of volatilization. Mass exchange caused by turbulent fluctuation is stronger in the direction normal to the air-water interface than in other directions due to the large density difference between water and air. In order to explore the characteristics of anisotropic diffusion of the volatile pollutants at the air-water interface, the relationship between velocity gradient and mass transfer rate was established to calculate the turbulent mass diffusivity. A second-order accurate smooth transition differencing scheme (STDS was proposed to guarantee the boundedness for the flow and mass transfer at the air-water interface. Simulations and experiments were performed to study the trichloroethylene (C2HCl3 release. By comparing the anisotropic coupling diffusion model, isotropic coupling diffusion model, and non-coupling diffusion model, the features of the transport of volatile pollutants at the air-water interface were determined. The results show that the anisotropic coupling diffusion model is more accurate than the isotropic coupling diffusion model and non-coupling diffusion model. Mass transfer significantly increases with the increase of the air-water relative velocity at a low relative velocity. However, at a higher relative velocity, an increase in the relative velocity has no effect on mass transfer.

    Demolishing outdated structures from the US Department of Energy Hanford Site in Washington, generates large quantities of waste which can be minimized. The Hanford cleanup is one of the world's largest and most complex environmental restoration efforts. Approximately 280 square miles of ground water and soil are contaminated; there are more than 80 surplus facilities, including nine shut-down nuclear reactors in various stages of decay; and there are 177 underground waste storage tanks containing highly radioactive waste. In all, 1,500 cleanup sites have been identified and the Environmental Restoration Contractor (ERC) is currently responsible for surveillance and maintenance of 170 structures. A two hour orientation training in pollution prevention was developed by the Westinghouse Hanford Company to provide all Decontamination and Decommissioning/Environmental Restoration (D ampersand D/ER) personnel with the knowledge to apply waste minimization principles during their cleanup activities. The ERC Team Pollution Prevention Workshop serves to communicate pollution prevention philosophies and influences the way D ampersand D/ER projects are conducted at the Hanford Site

    Most potentially toxic chemicals eventually find their way into waterways. The most common source of this pollution is from the air. More than 50 percent of the chemical pollution of the Great Lakes is believed to come from airborne pollutants, and the main sources of this pollution are smokestacks (energy plants, nuclear or conventional; trash-to-steam incinerators; industrial factories, chemical and wood pulp) and road traffic exhaust. Chemicals may reach waterways directly through partially filtered or untreated sewage and waterway traffic, both industrial and pleasure; or they may be deposited into the soil and reach rivers and estuaries through leakage (PCBs on cables, landfills, and regular or low-level nuclear waste) or locally from fields (fertilizers, herbicides, phosphates, and other chemicals). 26 references

    Industrialization in developing countries is causing increasing environmental damage. Pollution prevention (P2) is an emerging environmental concept that could help developing countries achieve leapfrog goals, bypassing old and pollutive technologies and minimizing traditional control practices. The current P2 promotion activities in Hong Kong, the Republic of Korea, the Philippines, Singapore, Taiwan, and Thailand are discussed. These programs, generally initiated in the last 5 years, are classified into five categories: awareness promotion, education and training, information transfer, technical assistance, and financial incentives. All important at the early stages of P2 promotion, these programs should inform industries of the benefits of P2 and help them identify applicable P2 measures. Participation in these programs is voluntary. The limited data indicate that adoption of P2 measures in these countries is not yet widespread. Recommendations for expanding P2 promotion activities include (1) strengthening the design and enforcement of environmental regulations; (2) providing P2 training and education to government workers, nongovernmental organizations and labor unions officials, university faculties, and news media; (3) tracking the progress of P2 programs; (4) implementing selected P2 mandatory measures; (5) identifying cleaner production technologies for use in new facilities; (6) implementing special programs for small and medium enterprises; and (7) expanding P2 promotion to other sectors, such as agriculture and transportation, and encouraging green design and green consumerism.

    Traditionally, pollution prevention (P2) assessments have been performed on existing facilities and ongoing operations, well after the completion of design and construction. It has been theorized that more success can be achieved by moving P2 upstream into the design process, where an estimated 70% of a project's total life cycle costs are initially fixed. Decisions made during design to prevent or minimize the amount of waste generated can reap benefits for many years to come. This is especially true when designing systems for handling hazardous and radioactive wastes for treatment, storage, and disposal. P2 assessments performed during design of such projects can uncover significant savings to be reaped during project construction, operations, and/or decommissioning. However, many project managers are still reluctant to include some type of P2 review or assessment as part of the design effort, because the immediate payback to the design entity is difficult to quantify. This paper presents the results of a P2 assessment performed on a design project at Hanford which identified close to $500,000 in construction savings while minimizing low-level and mixed radioactive waste generation. This paper describes the process used to per-form the assessment, discusses its results, and provides lessons-learned for future P2 design assessments

    1999-12-01

    Following the economic development and the progress of urbanization, the damage on water pollution has been more serious but a social cost caused by water pollution cannot be measured. Although the need of water quality preservation is emphasized, a base material for public investment on enhancing water quality preservation is not equipped yet due to the absence of economic values of water resource. Therefore it measured a cost generated by leaving pollution not treated water quality in this study. To measure the usable value of water resource or the cost of water pollution all over the country should include a national water system, but this study is limited on the mainstream of Han River water system from North Han River through Paldang to Chamsil sluice gates. Further study on Nakdong River and Keum River water systems should be done. 74 refs., 4 figs., 51 tabs.

    Lewis, R.A.

    1996-03-01

    This plan contains the Environmental Restoration Contractor (ERC) Waste Minimization and Pollution Prevention (WMin/P2) Program. The plan outlines the activities and schedules developed by the ERC to reduce the quantity and toxicity of waste dispositioned as a result of restoration and remediation activities. This plan satisfies US Department of Energy (DOE) requirements including the Pollution Prevention Awareness program required by DOE Order 5400.1 (DOE 1988). This plan is consistent with Executive Order 12856 and Secretary O'Leary's pollution prevention Policy Statement of December 27, 1994, which set US and DOE pollution prevention policies, respectively. It is also consistent with the DOE Pollution Prevention Crosscut Plan, 1994, which provides guidance in meeting the DOE goals in pollution prevention. The purpose of this plan is to aid ERC projects in meeting and documenting compliance with requirements for WMin/P2. This plan contains the objectives, strategy, and support activities of the ERC Team WMin/P2 program. The basic elements of the plan are pollution prevention goals, waste assessments of major waste streams, implementation of feasible waste minimization opportunities, and a process for reporting achievements. Wherever appropriate, the ERC will integrate the pollution prevention activities in this plan into regular program activities rather than establishing separate WMin/P2 activities. Moreover, wherever possible, existing documents, procedures, and activities will be used to meet WMin/P2 requirements

    International Nuclear Information System (INIS)

    Hauser, T.R.

    1991-01-01

    The EPA Science Advisory Board recommended that in the decade of the 1990's, EPA strategy should focus on the long-term goal of preventing and reducing environmental risk and should shift from end-of-pipe controls to preventing the generation of pollution. To assist EPA in developing and implementing this philosophy, the American Institute for Pollution Prevention (AIPP) was founded jointly by EPA and the University of Cincinnati in June, 1989. The mission of the Institute is to generate broad support from private and public sectors and to assist EPA in achieving widespread and expeditious adoption of pollution prevention concepts. AIPP will provide a novel communication bridge between EPA and industry. AIPP will provide and promote liasion between professionals in the field of pollution and those who need to employ new and improved pollution prevention techniques

    Full Text Available After the Three Gorges Reservoir starts running, it can not only take into consideration the interest of departments such as flood control, power generation, water supply, and shipping, but also reduce or eliminate the adverse effects of pollutants by discharge regulation. The evolution of pollutant plumes under different operation schemes of the Three Gorges Reservoir and three kinds of pollutant discharge types were calculated with the MIKE 21 AD software. The feasibility and effectiveness of the reservoir emergency operation when pollution accidents occur were investigated. The results indicate that the emergency operation produces significant effects on the instantaneous discharge type with lesser effects on the constant discharge type, the impact time is shortened, and the concentration of pollutant is reduced. Meanwhile, the results show that the larger the discharge is and the shorter the operation duration is, the more favorable the result is.

    2017-01-01

    With rapid urbanization and development of transport infrastructure, air pollution caused by multiple-pollutant emissions and vehicle exhaust has been aggravated year by year in China. In order to improve air quality, the Chinese authorities have taken a series of actions to control air pollution emission load within a permissible range. However, although China has made positive progress on tackling air pollution, these actions have not kept up with its economy growth and fossil-fuel use. The traditional single-pollutant approach is far from enough in China now, and in the near future, air pollution control strategies should move in the direction of the multiple-pollutant approach. In addition, undesirable air quality is usually linked with the combination of high emissions and adverse weather conditions. However, few studies have been done on the influence of climate change on atmospheric chemistry in the global perspective. Available evidence suggested that climate change is likely to exacerbate certain kinds of air pollutants including ozone and smoke from wildfires. This has become a major public health problem because the interactions of global climate change, urban heat islands, and air pollution have adverse effects on human health. In this chapter, we first review the past and current circumstances of China's responses to air pollution. Then we discuss the control challenges and future options for a better air quality in China. Finally, we begin to unravel links between air pollution and climate change, providing new opportunities for integrated research and actions in China.

    Stormwater in urban areas comprises of a substantial part of the urban water cycle, dominating the flow in many small urban streams, and the pollution levels are sizeable. No stormwater quality criteria were found here and no European or national emission limit values exist. Stormwater pollutants...... however are present in levels exceeding most of the regulated surface water quality criteria and environmental quality standards. Therefore catchment characterisation is needed to chose suitable treatment prior to discharge into receiving surface waters, as the mixing may be insufficient in small streams....

    Full Text Available Oil and gas exploration and production are two of the activities that potentially cause pollution and environmental damage. The largest waste generated from this activity is produced water. Produced water contains hazardous pollutants of both organic and inorganic materials, so that the produced water of oil and gas production cannot be discharged directly to the environment. Uncontrolled discharge can lead to the environmental damage, killing the life of water and plants. The produced water needs to be handled and fulfill the quality standards before being discharged to the environment. Several studies to reduce the contaminants in the produced water were conducted by researchers. Among them were gravity based separation - flotation, separation technique based on filtration, and biological process treatment. Therefore, some of these methods can be used as an alternative waste handling of produced water.

    The hypothesis that most human tumors are caused by toxic substances found in the environment, and that their onset is therefore basically predictable, is earning wider and wider consent. The results of experimental studies carried out on animals have shown that some of the chemical pollutants found in drinking water possess cancerogenous activity. Their origin and can vary a lot because most public water supplies come from rivers, lakes, or from groundwater tables, and, therefore, contain pollutants from agricultural land waste water, from industrial waste and from deliberate or accidental inputs. As a consequence, this kind of pollution can involve some risks for human health as a result of both direct use of tainted water or indirect use through food [it

    1996-08-01

    The projects were a series of pilot projects developed for DOE with the intention of transferring pollution prevention technology to private industry. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education program, the microscale cost benefit study, and the Bethel New Life recycling trainee program. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The recycle trainee project provided training for two participants and identified recycling and source reduction opportunities in Argonne`s solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identification of target technologies that were already available, identification of target audiences, and a focus of effort to achieve a limited but defined objective.

  6. Annual report of waste generation and pollution prevention progress 1997

    1998-09-01

    This sixth Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 36 reporting sites from 1993 through 1997. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive and hazardous waste generation, to be achieved by December 31, 1999. Excluding sanitary waste, routine operations waste generation increased three percent from 1996 to 1997, and decreased 61 percent overall from 1993 to 1997. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1997 waste generation to the 1993 baseline. However, it is important to note that increases in low-level radioactive and low-level mixed waste generation could reverse this achievement. From 1996 to 1997, low-level radioactive waste generation increased 10 percent, and low-level mixed waste generation increased slightly. It is critical that DOE sites continue to reduce routine operations waste generation for all waste types, to ensure that DOE's Complex-Wide Waste Reduction Goals are achieved by December 31, 1999

    Despite the increasing levels of pollution in many tropical African countries, not much is known about the strength and weaknesses of policy and institutional frameworks to tackle pollution and ecological status of rivers and their impacts on the biota. We investigated the ecological status of four large river basins using physicochemical water quality parameters and bioindicators by collecting samples from forest, agriculture, and urban landscapes of the Nile, Omo-Gibe, Tekeze, and Awash River basins in Ethiopia. We also assessed the water policy scenario to evaluate its appropriateness to prevent and control pollution. To investigate the level of understanding and implementation of regulatory frameworks and policies related to water resources, we reviewed the policy documents and conducted in-depth interviews of the stakeholders. Physicochemical and biological data revealed that there is significant water quality deterioration at the impacted sites (agriculture, coffee processing, and urban landscapes) compared to reference sites (forested landscapes) in all four basins. The analysis of legal, policy, and institutional framework showed a lack of cooperation between stakeholders, lack of knowledge of the policy documents, absence of enforcement strategies, unavailability of appropriate working guidelines, and disconnected institutional setup at the grass root level to implement the set strategies as the major problems. In conclusion, river water pollution is a growing challenge and needs urgent action to implement intersectoral collaboration for water resource management that will eventually lead toward integrated watershed management. Revision of policy and increasing the awareness and participation of implementers are vital to improve ecological quality of rivers.

    Water contamination is one of the major environmental pollution problems facing Pakistan because it has a direct impact on the health of human beings and crops. Lahore Canal water is being used both for irrigation and a source of ground water recharge. For the best use of this water, extent of pollution and its effect on soil hydraulic properties needs to be studied. For this purpose, water samples from twenty three sites and soil samples from three sites were collected along the Canal within the city limits of Lahore. The survey of the area from Jallo Park to Mall Road, show that all the abadies/colonies and industries situated on both sides of the canal dump their waste water and garbage in to canal. This result in increase of salinity as well as BOD and COD values which were found maximum at the locations of Herbuns Pura, Mughal Pura Dharam Pura, and Thoker Niaz Baig. (authors)

    Problems of and main limiting factors to Chinese western eco-environment are analyzea firstly and principles of integrating water pollution control with water resources planning and management, with ecological construction and with economic development planning and setting control priorities according to local conditions are proposed. Following strategies for water pollution control are suggested: 1) a master plan for western area need to be established as soon as possible; 2) total emission control should be regarded as the basic policy and measures such as clean production, charging and subsidy need to be implemented; 3) point sources pollution control should be considered the main task in short term and centralized wasteweter treatment plants by using sustainable processes should be constructed primarily for large and medium-size cities with heavier pollution; 4) sound institutional and regulation systems need to be established to create an enabling environment; 5) multiple investment system should be established; and 6) studies of pragmatic theories and methodologies for water pollution control and cost-effective technologies appropriate to western area, and training of local technicians need to be enhanced as well.

    Arbona, S.I.

    1991-01-01

    In Puerto Rico, previous water-quality analyses have indicated that most surface-water bodies, as well as ground water, are polluted with both organic and inorganic substances. Contributions to water-quality deterioration come from point and nonpoint sources. These pose a threat on a densely populated island. Urban and industrial development occurred rapidly with a lag in the required infrastructure for expansion. Water pollution has been a by-product of this process and is regarded as the most serious environmental problem on the island. This study examines water-quality parameters in three hydrological basins. It attempts to determine how extensive a problem it is and how the concentration of pollutants compare in different land-use situations. A total of 33 sampling sites distributed among the three watersheds was chosen. Fifteen water-quality parameters were examined. All of the water bodies in spatial association with the land use considered presented detectable concentrations of the selected water-quality parameters

    Full Text Available The paper proposed herewith aims to give an overview on the pollution along the Danube River. Water quality in Danube River basin (DRB is under a great pressure due to the diverse range of the human activities including large urban center, industrial, agriculture, transport and mining activities. The most important aspects of the water pollution are: organic, nutrient and microbial pollution, , hazardous substances, and hydro-morphological alteration. Analysis of the pressures on the Danube River showed that a large part of the Danube River is subject to multiple pressures and there are important risks for not reaching good ecological status and good chemical status of the water in the foreseeable future. In 2009, the evaluation based on the results of the Trans National Monitoring Network showed for the length of water bodies from the Danube River basin that 22% achieved good ecological status or ecological potential and 45% river water bodies achieved good chemical status. Another important issue is related to the policy of water pollution.

    The complexity of an aquatic system requires consideration of its dynamics: spatial and temporal variations of physical, chemical and biological. Heavy metals have peculiar behavior in the aquatic system and may not be available in the waters, but on sediments.The sub-basin of the Sarandi stream is responsible for the contamination of Pampulha Lake. The Instituto Mineiro das Águas – IGAM - uses tool for monitoring the quality of surface water for developing strategies for conservation, restoration and rational use of water resources. So through the indices: IQA ( Indice de qualidade de águas) Index of water quality, and TC- toxic contamination, reduces conflicts, implements the disciplining of the environmental economy.This study determined the monitoring of sediment and water of Sarandi Stream, so in the samples collected during dry and rainy seasons (2007- 2008) were analyzed heavy metals (Cu, Cd, Cr, Co, Ni, Zn, Pb) and physical-chemical factors (conductivity, solids dissolved, temperature, turbidity). This allowed the determination of Hackanson factors of contamination and Muller Index geoaccumulation, indicating very high contamination in sediments regarding the elements Cr, Cu, and Cd, and high contamination for Pb, Zn, and Mn. The comparison with the indices of water quality- IQA (IGAM - 2006, 2007 and 2008), combined with exploratory data analysis and graphs of correlation between the variables indicated favorable conditions for metals contamination on water and sediment for these metals, besides allowing the identification of its source

    Water environment problems induced by mining were studied. Influences of coal mining on runoff of rivers and on water sources were discussed. And the forming mechanism of acid water was analysed. The result shows that the mining activity is gradually changing the co-environment of adjacent areas, especially the water. With the water sources being continually polluted, the underground water has some poisonous or harmful ions in the process of dynamic exchange of water. The falling level of water table results in an increase of depression cone, and the seepage of rivers and the increasing range of acid water have more or less influence on water sources. All these are threatening the normal life of human beings. 11 refs., 2 figs.

  3. Effect of air and water pollutants on human health

    The two basic approaches in the study of the influence of air and water pollutants on human health are reviewed. The first one is an experimental or toxicological approach, concerned with biochemical, physiological, and clinical lesions, with the mechanism of the genesis of such lesions, and with the possible relations between the toxic dose and the extent or degree of the lesions. Thus, considerable changes in the electrolyte and trace element concentrations in the organism were observed following short-term exposure to such air pollutants as ozone and nitrogen dioxide which cause emphysema in a short time. Rather stable equilibrium between the uptake and excretion of lead was established. The increase in the blood lead level is accompanied by a decrease in the aminolevulinic acid dehydratase activity, a change believed to have no functional consequence. The other, epidemiological, approach is based on the study of human populations actually exposed to pollutants in daily life. Such epidemiological studies are complicated by the large number of extraneous variables playing a significant role in such discrete effects. Epidemiological studies are concerned with the establishment of relationships between specific or nonspecific mortality and morbidity associated with the actual pollution level as compared with control areas and control populations. A qualitative relationship between the increasing pollution level and advanced date of death was determinef for populations with respiratory and cardiovascular diseases. A relationship was found between the high pollution level and the number of patients hospitalized during high-pollution in Los Angeles.

    Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from marine resource appreciation. Water pollution delivery reduction costs are, however, not equal across abatement and treatment options. In this paper, an optimal control approach is developed and applied to explore welfare maximizing rates of water pollution abatement and/or treatment for efficient diffuse source water pollution management in terrestrial-marine systems. For the case of diffuse source dissolved inorganic nitrogen water pollution in the Tully-Murray region, Queensland, Australia, (agricultural) water pollution abatement cost, (wetland) water pollution treatment cost and marine benefit functions are determined to explore welfare maximizing rates of water pollution abatement and/or treatment. Considering partial (wetland) treatment costs and positive water quality improvement benefits, results show that welfare gains can be obtained, primarily, through diffuse source water pollution abatement (improved agricultural management practices) and, to a minor extent, through diffuse source water pollution treatment (wetland restoration).

    Measurement of the intensity of light reflected from various planar liquid surfaces has been performed. The results of this brief study show that the presence of a film of foreign material floating on a reference substrate is easily detected by reflectance measurement if the two liquids possess significantly different refractive indices, for example, oil (n = 1.40) and water (n = 1.33). Additional study of various optical configurations, and the building and testing of a prototype monitoring device revealed that the method is sufficiently practical for application to continuous water quality monitoring.

    2014-10-01

    Full Text Available This research paper aims to recommend control measures directed towards preventing and minimizing pollution, looking forward to the improvement of the environmental management on the sugar industry in Mexico. This issue has been put on hold due to the necessity to address the economic, social and technological issues affecting it over time. In order to better understand the productive process and the actual problem that the industry is facing, while proposing effective and possible actions for improvement, a sugar mill type was selected as a case of study. A comprehensive assessment of the production process for the standard sugar was made, considering the activities in the field and at the mill. The proposed measures in the sugar mill allowed savings in consumption of ground water average 3,620 cubic meters per day, during the period of study, reduction in solid waste generated average 325 kilograms per day by implementing a waste separation program, and reducing atmospheric emissions of particles acting as fuel for a boiler operated with bagasse. The prevention, minimization and pollution control measures proposed can be applied to other mills in the country with the appropriate adaptations.

  11. Pollutant source identification model for water pollution incidents in small straight rivers based on genetic algorithm

    2017-07-01

    Identification of pollutant sources for river pollution incidents is an important and difficult task in the emergency rescue, and an intelligent optimization method can effectively compensate for the weakness of traditional methods. An intelligent model for pollutant source identification has been established using the basic genetic algorithm (BGA) as an optimization search tool and applying an analytic solution formula of one-dimensional unsteady water quality equation to construct the objective function. Experimental tests show that the identification model is effective and efficient: the model can accurately figure out the pollutant amounts or positions no matter single pollution source or multiple sources. Especially when the population size of BGA is set as 10, the computing results are sound agree with analytic results for a single source amount and position identification, the relative errors are no more than 5 %. For cases of multi-point sources and multi-variable, there are some errors in computing results for the reasons that there exist many possible combinations of the pollution sources. But, with the help of previous experience to narrow the search scope, the relative errors of the identification results are less than 5 %, which proves the established source identification model can be used to direct emergency responses.

  12. Pollution source localization in an urban water supply network based on dynamic water demand.

    2017-10-27

    Urban water supply networks are susceptible to intentional, accidental chemical, and biological pollution, which pose a threat to the health of consumers. In recent years, drinking-water pollution incidents have occurred frequently, seriously endangering social stability and security. The real-time monitoring for water quality can be effectively implemented by placing sensors in the water supply network. However, locating the source of pollution through the data detection obtained by water quality sensors is a challenging problem. The difficulty lies in the limited number of sensors, large number of water supply network nodes, and dynamic user demand for water, which leads the pollution source localization problem to an uncertainty, large-scale, and dynamic optimization problem. In this paper, we mainly study the dynamics of the pollution source localization problem. Previous studies of pollution source localization assume that hydraulic inputs (e.g., water demand of consumers) are known. However, because of the inherent variability of urban water demand, the problem is essentially a fluctuating dynamic problem of consumer's water demand. In this paper, the water demand is considered to be stochastic in nature and can be described using Gaussian model or autoregressive model. On this basis, an optimization algorithm is proposed based on these two dynamic water demand change models to locate the pollution source. The objective of the proposed algorithm is to find the locations and concentrations of pollution sources that meet the minimum between the analogue and detection values of the sensor. Simulation experiments were conducted using two different sizes of urban water supply network data, and the experimental results were compared with those of the standard genetic algorithm.

  13. The Overview Of Water Pollution In The World

    2017-08-01

    Full Text Available Water is a precious resource but not everyone is aware of it. More than 1 billion people are missing about 20 to 50 liters of clean water each day to cater for basic needs such as eating and bathing. The phenomenon of oil exploration ocean shipping and petroleum-contaminated wastes is one of the causes of water pollution. It is estimated that about 1 billion tons of oil are transported by sea each year. Part of this volume about 0.1 to 0.3 is thrown into the sea in a relatively legal way the washing of oil tankers with seawater. The shipwreck is relatively regular disposal of lubricant or accidental dropping gasoline. The permeation rate of petroleum is seven times that of water which will cause the groundwater to become contaminated. About 1.6 million tons of hydrocarbons are discharged by rivers of industrialized nations. From the above causes we see that human consciousness is the main cause of pollution of water environment. Resources are not endless with the exploitation of an indiscriminate wing rampant run for market economy benefits without the appropriate treatment the water pollution is a certain matter. The importance is inevitable if people are unaware of the importance of water for life in the near future the resources will be exhausted.

    In a colliery currently being re-mined by opencast methods, the coal seam was originally extracted using bord and pillar mining. Depressions in the seam floor have facilitated the formation of large underground water bodies. This water has become acidic and contaminated by heavy metals. Mine water is treated by a liming plant and then released into evaporation pans. Seepage from the pans enters a natural wetlands. The de-watering of old workings ahead of mining periodically subjects the liming plant to large quantities of low quality water, and a nett export of salts such as sulphate occurs. As the mine is situated in a sensitive river catchment, this pollution is unacceptable. A chemical speciation program developed by the US Environmental Protection Agency was used to analyse effluent from the liming plant and wetland. Liming plant effluent water was found to vary greatly due to the conditions prevalent in the different water bodies. The liming plant and wetland were periodically subjected to pollution loads beyond the wetland`s assimilative capacity, resulting failure of the system. Despite this, the software provided evidence of the wetland`s pollution-ameliorating potential. 8 refs., 12 figs.

    Conservation in urban areas typically focuses on biodiversity and large green spaces. However, opportunities exist throughout urban areas to enhance ecological functions. An important function of urban landscapes is retaining nitrogen thereby reducing nitrate pollution to streams and coastal waters. Control of nonpoint nitrate pollution in urban areas was originally based on the documented importance of riparian zones in agricultural and forested ecosystems. The watershed and boundary frameworks have been used to guide stream research and a riparian conservation strategy to reduce nitrate pollution in urban streams. But is stream restoration and riparian-zone conservation enough? Data from the Baltimore Ecosystem Study and other urban stream research indicate that urban riparian zones do not necessarily prevent nitrate from entering, nor remove nitrate from, streams. Based on this insight, policy makers in Baltimore extended the conservation strategy throughout larger watersheds, attempting to restore functions that no longer took place in riparian boundaries. Two urban revitalization projects are presented as examples aimed at reducing nitrate pollution to stormwater, streams, and the Chesapeake Bay. An adaptive cycle of ecological urban design synthesizes the insights from the watershed and boundary frameworks, from new data, and from the conservation concerns of agencies and local communities. This urban example of conservation based on ameliorating nitrate water pollution extends the initial watershed-boundary approach along three dimensions: 1) from riparian to urban land-water-scapes; 2) from discrete engineering solutions to ecological design approaches; and 3) from structural solutions to inclusion of individual, household, and institutional behavior.

  16. The Synergic Characteristics of Surface Water Pollution and Sediment Pollution with Heavy Metals in the Haihe River Basin, Northern China

    Full Text Available Aquatic environmental deterioration is becoming a serious problem due to rapid urbanization and economic development, particularly in developing countries. As two important components of the aquatic environment, water quality and sediment pollution are widely considered to be concerns; however, they are considered separately in most cases. The relationship between water quality and sediment pollution with heavy metals has been little addressed. In this study, the Haihe River Basin (HRB, one of the most polluted areas in China, was used as a case study, and the eutrophication index (EI and the potential ecological risk index (RI were employed to evaluate water quality and sediment pollution of heavy metals, respectively. The results showed that generally in the HRB, the water quality was poor, while the risk of heavy metal pollution was relatively low. Surface water quality was mainly influenced by sewage discharges from human daily life, and heavy metal pollution was affected by industry structure, in that the areas with resource/energy consumption industries and high-pollution industries often have high risks of heavy metal pollution Synergic pollution from water eutrophication and sediment pollution with heavy metals was found, especially in the central areas of the HRB, and it was largely dependent on the type of human activities. In the places with intensive human activities, such as secondary industry, eutrophication occurred simultaneously with heavy metal pollution, other than in less human-affected areas. These findings are useful for planning aquatic environment protections and river ecosystem management.

    China's Central government has released an ambitious plan to tackle the nation's water pollution crisis. However, this is inhibited by a lack of data, particularly for groundwater. We compiled and analyzed water quality classification data from publicly available government sources, further revealing the scale and extent of the crisis. We also compiled nitrate data in shallow and deep groundwater from a range of literature sources, covering 52 of China's groundwater systems; the most comprehensive national-scale assessment yet. Nitrate pollution at levels exceeding the US EPA's maximum contaminant level (10 mg/L NO 3 N) occurs at the 90th percentile in 25 of 36 shallow aquifers and 10 out of 37 deep or karst aquifers. Isotopic compositions of groundwater nitrate (δ 15 N and δ 18 O NO3 values ranging from -14.9‰ to 35.5‰ and -8.1‰ to 51.0‰, respectively) indicate many nitrate sources including soil nitrogen, agricultural fertilizers, untreated wastewater and/or manure, and locally show evidence of de-nitrification. From these data, it is clear that contaminated groundwater is ubiquitous in deep aquifers as well as shallow groundwater (and surface water). Deep aquifers contain water recharged tens of thousands of years before present, long before widespread anthropogenic nitrate contamination. This groundwater has therefore likely been contaminated due to rapid bypass flow along wells or other conduits. Addressing the issue of well condition is urgently needed to stop further pollution of China's deep aquifers, which are some of China's most important drinking water sources. China's new 10-point Water Pollution Plan addresses previous shortcomings, however, control and remediation of deep groundwater pollution will take decades of sustained effort. Copyright © 2016.

    2017-03-01

    Full Text Available Background & Objective: Nowadays, according to growth of industry and increasing population, water resources are seriousely shortened. This lack of water resources will require special management to be considered in industry and agriculture. Among the various sources of water, surface waters are more susceptible to infection. The most important of these sources of pollution are industrial pollution, detergent, pesticides, radioactive materials, heat and salt concentration.  Materials & methods: In this article, at first the importance of each pollutant will be evaluated base on the effects and its results and then quality evaluation of surface water will be studied. In order to assess the relative importance of these pollutants primarily using TOPSIS software, prioritize these factors as one of the hierarchical analysis and then is modeled with decision tree method using Weka software, the importance of each factor is evaluated and if it does not meet the minimal importance of the decision tree will be removed. Results: The results obtained from the Topsis fuzzy analysis indicate that surface water and groundwater are exposed to pollution about 74% and 26% respectively among the six pollutants examined in this study. In addition, results obtaned from the hierarchical tree in software Weka has shown that the heat factor, soluble salts and industrial pollutants give impac factor or purity about 0.1338, 0.0523 and 1.2694 respectively. Conclusion: Surface water is at greater risk of being polluted compared with groundwater. The heat factor and low concentration of dissolved salts have the low impact and industrial pollutants are considered as the most influential factors in surface water pollution.

    2014-02-01

    In order to reduce the losses by water pollution, forewarning model for water pollution risk based on Bayes theory was studied. This model is built upon risk indexes in complex systems, proceeding from the whole structure and its components. In this study, the principal components analysis is used to screen out index systems. Hydrological model is employed to simulate index value according to the prediction principle. Bayes theory is adopted to obtain posterior distribution by prior distribution with sample information which can make samples' features preferably reflect and represent the totals to some extent. Forewarning level is judged on the maximum probability rule, and then local conditions for proposing management strategies that will have the effect of transforming heavy warnings to a lesser degree. This study takes Taihu Basin as an example. After forewarning model application and vertification for water pollution risk from 2000 to 2009 between the actual and simulated data, forewarning level in 2010 is given as a severe warning, which is well coincide with logistic curve. It is shown that the model is rigorous in theory with flexible method, reasonable in result with simple structure, and it has strong logic superiority and regional adaptability, providing a new way for warning water pollution risk.

    Sandia National Laboratories, New Mexico (Sandia/NM) has successfully developed and implemented a chargeback system to fund the implementation of Pollution Prevention activities. In the process of establishing this system, many valuable lessons have been learned. This paper describes how the chargeback system currently functions, the benefits and drawbacks of implementing such a system, and recommendations for implementing a chargeback system at other facilities. The initial goals in establishing a chargeback system were to create (1) funding for pollution prevention implementation, including specific pollution prevention projects; and (2) awareness on the part of the line organizations of the quantities and types of waste that they generate, thus providing them with a direct incentive to reduce that waste. The chargeback system inputs waste generation data and then filters and sorts the data to serve two purposes: (1) the operation of the chargeback system; and (2) the detailed waste generation reporting used for assessing processes and identifying pollution prevention opportunities

    Prioritizing waste generators is necessary to determine which are the best candidates for Pollution Prevention Opportunity Assessments (PPOAs). This paper describes the Sandia National Laboratories/New Mexico (SNL/NM) PPOA Ranking System. The system uses a multimedia approach that considers hazardous and radioactive waste disposal data, and hazardous chemical usage data (from which air emissions are extrapolated). Pollution prevention information is included, from the SNL Pollution Prevention Opportunities database that identifies waste streams that have readily apparent pollution prevention opportunities. The system also considers the relative costs of waste management and the chargeback fees paid for waste generation. From these data, organizations are ranked with an algorithm developed in Microsoft Access trademark on a personal computer. The concept could readily be transferred to other facilities needing to decide where to perform PPOAs

    The Department of Energy and its contractors are faced with environmental concerns and large waste management costs. Federal legislation and DOE Orders require sites to develop waste minimization/pollution prevention programs. In response to these requirements, the Kansas City Plant developed a pollution prevention tool called a pollution prevention opportunity assessment (PPOA). Pilot assessments resulted in the development of a graded approach to reduce the amount of effort required for activities that utilized nonhazardous and/or low-volume waste streams. The project`s objectives in FY95 were to validate DOE`s PPOA Graded Approach methodology, provide PPOA training and technical assistance to interested DOE personnel and DOE contractors, enhance the methodology with energy analysis and tools for environmental restoration activities, implement a DOE-wide PPOA database, and provide support to DOE EM-334 in the completion of a report which estimates the future potential for pollution prevention and waste minimization in the DOE complex.

  1. Tackling non-point source water pollution in British Columbia: An action plan

    Energy Technology Data Exchange (ETDEWEB)

    1998-01-01

    Efforts to protect British Columbia water quality by regulating point discharges from municipal and industrial sources have generally been successful, and it is recognized that the major remaining cause of water pollution in the province is from non-point sources. These sources are largely unregulated and associated with urbanization, agriculture, and other forms of land development. The first part of this report reviews the provincial commitment to clean water, the effects of non-point-source (NPS) pollution, and the management of NPS in the province. Part 2 describes the main causes of NPS in British Columbia: Land development, agriculture, stormwater runoff, on-site sewage systems, forestry and range activities, atmospheric deposition, and boating/marine activities. Finally, it presents key components of the province's NPS action plan: Education and training, prevention at site, land use planning and co-ordination, assessment and reporting, economic incentives, legislation and regulation, and implementation.

    A parameter estimation procedure for a water pollution transport model is elaborated. A two-dimensional instantaneous-release shear-diffusion model serves as representative of a simple transport process. Pollution concentration levels are arrived at via modeling of a remote-sensing system. The remote-sensed data are simulated by adding Gaussian noise to the concentration level values generated via the transport model. Model parameters are estimated from the simulated data using a least-squares batch processor. Resolution, sensor array size, and number and location of sensor readings can be found from the accuracies of the parameter estimates.

  5. Self-Propelled Micromotors for Cleaning Polluted Water

    Science.gov (United States)

    2013-01-01

    We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional nanomembranes consisting of Fe/Pt bilayers. The micromotors contain double functionality within their architecture, i.e., the inner Pt for the self-propulsion and the outer Fe for the in situ generation of ferrous ions boosting the remediation of contaminated water.The degradation of organic pollutants takes place in the presence of hydrogen peroxide, which acts as a reagent for the Fenton reaction and as main fuel to propel the micromotors. Factors influencing the efficiency of the Fenton oxidation process, including thickness of the Fe layer, pH, and concentration of hydrogen peroxide, are investigated. The ability of these catalytically self-propelled micromotors to improve intermixing in liquids results in the removal of organic pollutants ca. 12 times faster than when the Fenton oxidation process is carried out without catalytically active micromotors. The enhanced reaction–diffusion provided by micromotors has been theoretically modeled. The synergy between the internal and external functionalities of the micromotors, without the need of further functionalization, results into an enhanced degradation of nonbiodegradable and dangerous organic pollutants at small-scale environments and holds considerable promise for the remediation of contaminated water.

    Understanding historical accidents is important for accident prevention and risk mitigation; however, there are no public databases of pollution accidents in China, and no detailed information regarding such incidents is readily available. Thus, 653 representative cases of surface water pollution accidents in China were identified and described as a function of time, location, materials involved, origin, and causes. The severity and other features of the accidents, frequency and quantities of chemicals involved, frequency and number of people poisoned, frequency and number of people affected, frequency and time for which pollution lasted, and frequency and length of pollution zone were effectively used to value and estimate the accumulated probabilities. The probabilities of occurrences of various types based on origin and causes were also summarized based on these observations. The following conclusions can be drawn from these analyses: (1) There was a high proportion of accidents involving multi-district boundary regions and drinking water crises, indicating that more attention should be paid to environmental risk prevention and the mitigation of such incidents. (2) A high proportion of accidents originated from small-sized chemical plants, indicating that these types of enterprises should be considered during policy making. (3) The most common cause (49.8 % of the total) was intentional acts (illegal discharge); accordingly, efforts to increase environmental consciousness in China should be enhanced.

    1993-01-01

    The serious environmental problems of the South Urals Region of Russia have been broadly described in a report coauthored by Russian weapons scientists. The importance of taking the first steps to prevent further environmental damage and adverse public health effects has been recognized by the international scientific community. Scientists at the Lawrence Livermore National Laboratory have initiated a project to assist the Russians in their pollution prevention efforts. The specific objectives of this project are to: (1) conduct a pragmatic survey of the industrial and governmental pollution sources in a limited geographic region of the South Urals and (2) identify the priorities for pollution prevention and for food and water supply improvements at distribution points. The emphasis is on preventing adverse impacts to human health and improving industrial productivity. This project focuses on immediate pollution problems resulting from current operations and their solutions, not on long-term research related to the large-scale cleanup of legacy wastes. The project emphasizes near-term cost effective solutions to prevent pollution while longer term research aimed at contamination from past practices is pursued by other scientists. The project is being conducted in collaboration with environmental and physical scientists from institutes associated with the Ural Branch of the Russian Academy of Sciences; government officials at the national, regional, and local levels; and non-governmental Russian environmental groups. A broad cross section of Russian technical, political, and environmental abilities and interests is mandatory. This cross section will ensure the technical quality, the political acceptability, and the popular credibility of the project results to the affected Russians in the South Urals. Progress on this project is presented in this paper

    Full Text Available Abstract Lead is an old environmental metal which is presented everywhere and lead poisoning is an important health issue in many countries in the world including Iran. It is known as a silent environmental disease which can have life-long adverse health effects. In children, the most vulnerable population, mental development of children health effects is of the greatest influence. Low level lead exposure can significantly induce motor dysfunctions and cognitive impairment in children. The sources of lead exposure vary among countries. Occupational lead exposure is an important health issue in Iran and mine workers, employees of paint factories, workers of copying centers, drivers, and tile making factories are in higher risk of lead toxicity. Moreover lead processing industry has always been a major of concern which affects surface water, drinking waters, and ground waters, even water of Caspian Sea, Persian Gulf and rivers due to increasing the number of industries in vicinity of rivers that release their waste discharges into river or sea. In addition, lead contamination of soil and air especially in vicinity of polluted and industrialized cities is another health problem in Iran. Even foods such as rice and fishes, raw milk, and vegetables which are the most common food of Iranian population are polluted to lead in some area of Iran. Adding lead to the opium is a recently health hazard in Iran that has been observed among opium addicts. There are few studies evaluated current status of lead exposure and toxicity in the Iranian children and pregnant women which should be taken into account of authorities. We recommend to identify sources, eliminate or control sources, and monitor environmental exposures and hazards to prevent lead poisoning.

    Full Text Available This ecocritical reading of Marie Luise Kaschnitz’s poetic cycle “Rückkehr nach Frankfurt” ‘Return to Frankfurt’ (1945/46, Hans Magnus Enzensberger’s epic poem Der Untergang der Titanic ‘ The Sinking of the Titanic ’ (1978, and a 21st-century poem by Ulrike Almut Sandig analyzes key shifts in poetic representations of water pollution. The essay explores underlying cultural and political attitudes about water that define literary depictions of its pollution. It argues that these texts register a conceptual turn away from aesthetic appreciation of water in terms of its culturally rich, purifying properties and toward scientific understanding that emphasizes the social and legal dimensions of water pollution. Ecocritical interpretation of such works, thus, enables deeper understanding of ongoing transformations in the lyric genre. The concluding interpretation of Sandig’s text points to the increasing presence of unnatural elements in representations of the environment as symptomatic of broader literary changes. It argues that developments in German nature poetry since 1945 have increasingly led poets to experiment with expressive possibilities for lyric poetry that foreground cathartic responses to human and environmental history.

  15. A Study on Water Pollution Source Localization in Sensor Networks

    Directory of Open Access Journals (Sweden)

    Jun Yang

    2016-01-01

    Full Text Available The water pollution source localization is of great significance to water environment protection. In this paper, a study on water pollution source localization is presented. Firstly, the source detection is discussed. Then, the coarse localization methods and the localization methods based on diffusion models are introduced and analyzed, respectively. In addition, the localization method based on the contour is proposed. The detection and localization methods are compared in experiments finally. The results show that the detection method using hypotheses testing is more stable. The performance of the coarse localization algorithm depends on the nodes density. The localization based on the diffusion model can yield precise localization results; however, the results are not stable. The localization method based on the contour is better than the other two localization methods when the concentration contours are axisymmetric. Thus, in the water pollution source localization, the detection using hypotheses testing is more preferable in the source detection step. If concentration contours are axisymmetric, the localization method based on the contour is the first option. And, in case the nodes are dense and there is no explicit diffusion model, the coarse localization algorithm can be used, or else the localization based on diffusion models is a good choice.

    Oil pollution of marine waters around Newfoundland, and particularly in the vicinity of Placentia Bay, is a frequent occurrence. Many oiled seabirds are found on beaches in the bay, particularly in winter. The most likely pollution sources are ship operators who dump waste oils from bilges and slop tanks. In an effort to reduce the chronic discharge of waste oil into Placentia Bay, and thus the incidence of bird oiling, Operation Clean Feather was launched in 1991-92 and consisted of weekly surveys of Placentia Bay beaches, sampling of oil from vessels using the bay and from oiled birds and beaches, and experimentation to determine possible recovery rates of birds oiled at sea. The operation was considered a success at a number of levels. Significant reductions in numbers of oiled birds were noted in both 1991 and 1992 compared to 1989 or 1990. Estimated oil-related mortality was reduced to ca 25% of levels seen in the two years prior to the operation. The operation also provided the opportunity to test and refine an organizational framework designed to deal with the problem of chronic oil pollution reports. Communication efforts heightened the awareness of the oil pollution problem in Newfoundland waters. These efforts included distribution of pamphlets in various languages to ship operators, describing the seriousness of oil-related marine bird mortality and warning of the substantial fines that can be imposed under the Canada Shipping Act. 6 refs., 3 figs., 1 tab

  19. Contribution of Nutrient Pollution to Water Scarcity in the Water-Rich Northeastern United States

    Hale, R. L.; Lopez, C.; Vorosmarty, C. J.

    2015-12-01

    Most studies of water stress focus on water-scarce regions such as drylands. Yet, even water-rich regions can be water stressed due to local water withdrawals that exceed supply or due to water pollution that makes water unusable. The northeastern United States (NE) is a water-rich region relative to the rest of the country, as it concentrates about 50% of total renewable water of the country. Yes the NE features relatively high water withdrawals, ~50 km3/yr, for thermo-power generation, agriculture, and industry, as well as to support a human population of about 70 million. At the same time, rivers and streams in the NE suffer from nutrient pollution, largely from agricultural and urban land uses. We asked: to what extent is the NE water stressed, and how do water withdrawals and water quality each contribute to water scarcity across the NE? We used information on county-level water withdrawals and runoff to calculate a water scarcity index (WSI) for 200 hydrologic units across the NE from 1987 to 2002. We used data on surface water concentrations of nitrogen to calculate the additional water necessary to dilute surface water pollution to weak, moderate, and strong water quality standards derived from the literature. Only considering withdrawals, we found that approximately 10% of the NE was water stressed. Incorporating a moderate water quality standard, 25% of the NE was water stressed. We calculated a dilution burden by sectors of water users and found that public utilities faced 41% of the total dilution burden for the region, followed by irrigation users at 21%. Our results illustrate that even water rich regions can experience water stress and even scarcity, where withdrawals exceed surface water supplies. Water quality contributes to water stress and can change the spatial patterns of water stress across a region. The common approach to address scarcity has required the use of inter-basin water transfers, or in the case of water quality-caused scarcity

    It is limited in conventional Soil Liner theory of waste landfill, we must update the theory and the calculational methods must be broke, so that the cost of waste landfill could be reduced in wide scope, this is important to develop economy and environment in sustaining rate. It is an innovation in the theory of the pollution control in the waste landfill groundwater through translated the theories of 'excluding infiltrate to groundwater' into 'insulating waste, allowing water into groundwater', the theory of waste landfill from pollution to groundwater came true. Clayey Soil not only can prevent seepage, but also can obstruct waste. If we can make use of its filtration adequately, just as using experimentation in laboratory to research filtration capability, calculation, we could made new testing technique and calculated technique of liner parameters. This paper take an example of which calculate to liner parameters, such as 'filtration capability' and 'adequacy thickness of effective liner', and make a programming of landfill site by this theory and method in Beijing plain.

  1. Drugs in Your Drinking Water: Removing Pharmaceutical Pollution

    Science.gov (United States)

    Richardson, K.

    2017-12-01

    Pharmaceuticals, mostly estrogen-based hormones and antibiotics, are increasingly polluting waterways and contaminating municipal drinking water sources. A 2008 study funded by the American Water Works Association Research Foundation and the WateReuse Foundation tested 19 drinking water treatment plants across the United States. The study found pharmaceuticals and metabolites at all of the locations tested. These plants provide drinking water for over 28 million Americans - yet only five states test for pharmaceuticals. A 2007 US Government Accountability Office study of male smallmouth bass showed ovarian tissue in their gonads and concluded the combination of EDCs (Endocrine Disrupting Chemicals) likely caused the feminization of the male fish. The purpose of this project is to determine whether bivalves can effectively remove pharmaceuticals as well as other CECs (Contaminants of Emerging Concern).Pharmaceuticals, specifically ibuprofen, were found to be resistant to chemical and mechanical filtration methods, such as coffee grounds and activated carbon, so biological filtration methods are used. Three types of common mollusks (Sphaeriidae `fingernail clams', freshwater mussels, scallops) will be used to assess the potential for biological remediation of the chemical pollutants. Fifteen specimens of each species will be used - a total of 45 individuals. Each group of five will be introduced to either an NSAID (ibuprofen), oil (vegetable) or hormone (estrogen, pending approval). This creates an array of 3 species and 3 contaminants, for a 3x3 grid of nine sample groups. Water is contaminated with pollutant levels similar to EPA measurements. The concentration will be measured before and after the introduction of the specimens using a UV spectrophotometer, at regular time intervals. As mollusks are capable of filtering up to two liters of water a day, the 37.8 liter tanks are filtered at a rate of 10 liters a day. A successful trial of bivalves reducing and

    The common standard method of sampling water born pollutants in the vadoze zone is core sampling and it is followed by extraction of pore fluid. This method does not allow sampling at the same location next time and again later on. There is an alternative approach for sampling fluids (water born pollutants) from both saturated and unsaturated regions of vadose zone using porous suction samplers. There are three types of porous suction samplers, vacuum-operated, pressure-vacuum lysimeters, high pressure vacuum samples. The suction samples are operated in the range of 0-70 centi bars and usually consist of ceramic and polytetrafluorethylene (PTFE). The operation range of PTFE is higher than ceramic cups. These samplers are well suited for in situ and repeated sampling form the same location. This paper discusses the physical properties and operating condition of such samplers to the utilized under our environmental sampling. (author)

    Full Text Available Testing of carbonaceous adsorbents for removal of pollutants from water. Relevant direction for improving of quality of potable water is application of active carbons at various stages of water treatments. This work includes complex research dealing with testing of a broad spectrum of carbonaceous adsorbents for removal of hydrogen sulfide and nitrite ions from water. The role of the surface functional groups of carbonaceous adsorbents, their acid-basic properties, and the influence of the type of impregnated heteroatom (N, O, or metals (Fe, Cu, Ni, on removal of hydrogen sulfide species and nitrite ions have been researched. The efficiency of the catalyst obtained from peach stones by impregnation with Cu2+ ions of oxidized active carbon was established, being recommended for practical purposes to remove the hydrogen sulfide species from the sulfurous ground waters. Comparative analysis of carbonaceous adsorbents reveals the importance of surface chemistry for oxidation of nitrite ions.

    Full Text Available Polluted water is causing serious health problems especially in the rural areas of Pakistan. People have limited access to safe water supply and many diseases like diarrhea and gastrointestinal diseases are transmitted by consumption of polluted water. We have investigated the potential of using solar energy to pasteurize water. Low cost indigenously available materials have been utilized to design and fabricate a solar box type pasteurizer having a capacity of three liters. The performance study of the pasteurizer was performed during the month of May 2008. The designed pasteurizer maintained water temperature in the range of60 oC to 70 oC continuously for more than an hour which is enough for deactivation of coliform bacteria. The maximum water temperature on a clear sunny day was found to be 67 oC, corresponding to an ambient temperature of40 oC. With the pasteurizer facing south, a very little repositioning was required. The low cost and operational simplicity of the pasteurizer make it affordable and usable. It is more useful in rural areas where other sources of energy like electricity and gas are not easily available

    In recent years, with the increasing world environmental pollution happening, sudden water pollution incident has become more and more frequently in China. It has posed a serious threat to water safety of the people living in the water source area. Conventional water pollution monitoring method is manual periodic testing, it maybe miss the best time to find that pollution incident. This paper proposes a water pollution warning framework to change this state. On the basis of the Internet of things, we uses automatic water quality monitoring technology to realize monitoring. We calculate the monitoring data with water pollution model to judge whether the water pollution incident is happen or not. Water pollution warning framework is divided into three layers: terminal as the sensing layer, it with the deployment of the automatic water quality pollution monitoring sensor. The middle layer is the transfer network layer, data information implementation is based on GPRS wireless network transmission. The upper one is the application layer. With these application systems, early warning information of water pollution will realize the high-speed transmission between grassroots units and superior units. The paper finally gives an example that applying this pollution warning framework to water quality monitoring of Beijing, China, it greatly improves the speed of the pollution warning responding of Beijing.

    With the tightening of budgets and limited resources, it is important to ensure operations are carried out in a cost-effective and productive manner. Implementing an effective Pollution Prevention strategy can help to reduce the costs of waste management and prevent harmful releases to the environment. This document provides an estimate of the Department of Energy's waste reduction potential from the implementation of Pollution Prevention opportunities. A team of Waste Minimization and Pollution Prevention professionals was formed to collect the data and make the estimates. The report includes a list of specific reduction opportunities for various waste generating operations and waste types. A generic set of recommendations to achieve these reduction opportunities is also provided as well as a general discussion of the approach and assumptions made for each waste generating operation

  15. Adaptive hierarchical grid model of water-borne pollutant dispersion

    Science.gov (United States)

    Borthwick, A. G. L.; Marchant, R. D.; Copeland, G. J. M.

    Water pollution by industrial and agricultural waste is an increasingly major public health issue. It is therefore important for water engineers and managers to be able to predict accurately the local behaviour of water-borne pollutants. This paper describes the novel and efficient coupling of dynamically adaptive hierarchical grids with standard solvers of the advection-diffusion equation. Adaptive quadtree grids are able to focus on regions of interest such as pollutant fronts, while retaining economy in the total number of grid elements through selective grid refinement. Advection is treated using Lagrangian particle tracking. Diffusion is solved separately using two grid-based methods; one is by explicit finite differences, the other a diffusion-velocity approach. Results are given in two dimensions for pure diffusion of an initially Gaussian plume, advection-diffusion of the Gaussian plume in the rotating flow field of a forced vortex, and the transport of species in a rectangular channel with side wall boundary layers. Close agreement is achieved with analytical solutions of the advection-diffusion equation and simulations from a Lagrangian random walk model. An application to Sepetiba Bay, Brazil is included to demonstrate the method with complex flows and topography.

  16. The History of Petroleum Pollution in Malaysia; Urgent Need for Integrated Prevention Approach

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Petroleum pollution is known as point and non-point source of contaminations in the environment. A major class of petroleum contaminant is groups of compounds consist of two or more fused benzene rings called polycyclic aromatic hydrocarbons (PAHs that are carcinogenic, mutagenic and toxic. Source identification of petroleum pollution is necessary to prevent pollution entry into the environment. Eight sedimentary cores were obtained from developed and developing areas around Peninsular Malaysia to investigate the historical profile of PAHs, their characteristics and its possible origins. The results showed that the PAHs concentrations varied from very minimum to 2400 ng/g d. w. in average quarter century intervals. Most of the studied locations showed high contribution of PAHs from combusted fuel, coal, biomasses and wood materials except for the southern part of Peninsular Malaysia in which revealed dominance of petroleum products. The findings indicate that PAHs are delivered from different intermediate materials such as asphalt, street dust, vehicular emission and crankcase oil. However, there has been a decline of PAHs input into the marine environment in recent years; petroleum is shown to be a significant cause of marine pollution since the second quarter of 20th century. An overview on sourced materials of petroleum pollution indicates multi-approach necessity toward pollution control, regardless of concentration and possible degradation processes. Various sectors both governmental and non-governmental are needed for prevention and control of petroleum pollution where different sources apparently contribute to the pollution generation process.

    Based on the data analysis of the water environmental quality and economic development from 2002 to 2012 in the Nansi Lake basin, the correlation and change between the water environmental quality and economic development were studied. Results showed that the GDP and wastewater emissions of point source in the Nansi Lake basin had an average annual growth of 7.30 and 7.68 %, respectively, from 2002 to 2012. The emissions of chemical oxygen demand (COD) and ammonia nitrogen (NH3-N) had the average annual decrease of 7.69 and 6.79 % in 2012, respectively, compared to 2002. Basin water quality overall improved, reaching the Class III of the "Environmental quality standards for surface water (GB3838-2002)," in which the main reason was that sewage treatment rate increased gradually and was above 90 % in 2012 (an increase of 10 % compared to 2002) with the progress of pollution abatement technology and the implementation of relevant policies and regulations. The contribution of water environmental pollution was analyzed from related cities (Ji'ning, Zaozhuang, Heze). Results indicated that Ji'ning had the largest contribution to water pollution of the Nansi Lake basin, and the pollutant from domestic sources accounted for a higher percentage compared to industrial sources. The wastewater, COD, and NH3-N mainly came from mining and washing of coal, manufacture of raw chemical materials and chemical products, papermaking industry, and food processing industry. According to the water pollution characteristics of the Nansi Lake basin, the basin pollution treatment strategy and prevention and treatment system were dissected to provide a scientific basis for prevention and control of lakeside point source pollution along the Nansi Lake.

    2014-10-01

    Full Text Available As the area of the Slovak Republic is 49,036 km², there are many potential contaminants that can affect its population. In the socialist era the town of Strážske located in the Košice Municipal Region was the centre of production of polychlorinated biphenyls (PCB inter alia and nowadays about 3,500 metric tonnes of PCB are persisting there and present the greatest PCB environmental risk in the central Europe. The heavy metal contamination in Slovakia is caused by the natural background as well as by the former mining activities. In Slovakia there are about 17 thousand old mining works, i.e. adits, stocks, and impoundments. Contamination of the ground and surface waters in the Spiš–Gemer Ore Mountain (SGOM area is caused by mine drainage. Arsenic, antimony, copper, mercury, cadmium, and zinc are the main pollutants of natural waters. All contaminated areas are currently monitored according to the national and EU legislation and nutrient load reduction programmes. As a result of this the level of inorganic and organic micropollutants in surface water and water reservoirs will be reduced together with the negative impact of water pollution on the environment in Eastern Slovakia region.

    2015-03-01

    Our knowledge relating to water contamination from point and diffuse sources has increased in recent years and there have been many studies undertaken focusing on effluent from sewage plants or combined sewer overflows. However, there is still only a limited amount of microbial data on non-point sources leading to diffuse pollution of surface waters. In this study, the concentrations of several indicator micro-organisms and pathogens in the upper reaches of a river system were examined over a period of 16 months. In addition to bacteria, diffuse pollution caused by Giardia lamblia and Cryptosporidium spp. was analysed. A single land use type predestined to cause high concentrations of all microbial parameters could not be identified. The influence of different land use types varies between microbial species. The microbial concentration in river water cannot be explained by stable non-point effluent concentrations from different land use types. There is variation in the ranking of the potential of different land use types resulting in surface water contamination with regard to minimum, median and maximum effects. These differences between median and maximum impact indicate that small-scale events like spreading manure substantially influence the general contamination potential of a land use type and may cause increasing micro-organism concentrations in the river water by mobilisation during the next rainfall event.

    The Environmental Restoration (ER) Program within Martin Marietta Energy Systems, Inc. is currently developing a more active waste minimization and pollution prevention program. To determine areas of programmatic improvements within the ER Waste Minimization and Pollution Prevention Awareness Program, the ER Program required an evaluation of the program across the Oak Ridge K-25 Site, the Oak Ridge National Laboratory, the Oak Ridge Y-12 Plant, the Paducah Environmental Restoration and Waste Minimization Site, and the Portsmouth Environmental Restoration and Waste Minimization Site. This document presents the status of the overall program as of fourth quarter FY 1994, presents pollution prevention cost avoidance data associated with FY 1994 activities, and identifies areas for improvement. Results of this assessment indicate that the ER Waste Minimization and Pollution Prevention Awareness Program is firmly established and is developing rapidly. Several procedural goals were met in FY 1994 and many of the sites implemented ER waste minimization options. Additional growth is needed, however, for the ER Waste Minimization and Pollution Prevention Awareness Program

    The result of the deteriorating condition of the environment and climate change is to increase the efficient use of fuel and energy and the rational use of energy resources. Great potential for reducing consumption of fossil fuels are stuck in heating systems ranging from generation, transmission and distribution and ending with the recipients rationalize their consumption of heat. Efficient production of heat is obtained during optimal boiler load. The boiler type WR operates with the highest efficiency of 80-85%, the rate of fuel consumption is the lowest, and the process is close to complete combustion. In such conditions to the atmosphere are emitted mainly: SO2, CO2 and NOX. Pollutants such as CO, CH4, HF, HCl, NH3, etc., are the result of incomplete and imperfect combustion, that is, when the boiler is working inefficiently [1-3]. Measurements of pollutant concentrations were performed using an analyzer FTIR Gasmet DX4000. Fourier Transform Infrared Spectroscopy is a technique of measuring that allows a very precise identification of qualitative and quantitative range of compounds, including gaseous pollutants. Device used to measure the concentrations of gaseous pollutants allow determining the amount of carbon, sulphur and nitrogen compounds, which measurement is not defined any rules, including chlorine compounds, hydrogen, methane, ammonia and volatile organic compounds. In this publication presents part of the literature the use of heat for domestic hot water production in summer and heating demand in winter. Described the characteristics of the water boilers WR type used for heating. Presents the results study of the emissions in the production of hot water for the summer and winter seasons.

    Japan`s balance in environmental-oriented water resources management is contradictory. Some improvements have been achieved, for instance in the treatment of industrial discharges and, in particular, in reducing emissions of toxic heavy metals. Conversely, with other forms of pollution, such as the organic load, no progress has been made so far; in some instances the situation has even deteriorated. However, measures for an advanced protection of waters are planned. New construction, extension, and modernization of wastewater treatment plants are a priority objective in environmental policy. A positive impact on water quality can be expected when the implementation of an emission-charges system for industries and the development of sewerage systems for households, based on the polluter-pays-principle, will be completed.

    Persistent organic pollutants represent about 95 % of the industrial sector effluents in Egypt. Contamination of the River Nile water with various pesticides poses a hazardous risk to both human and environmental compartments. Therefore, a large scale monitoring study was carried on pesticides pollution in three geographical main regions along the River Nil water stream, Egypt. Organochlorine and organophosphorus pesticides were extracted by liquid-liquid extraction and analyzed by GC-ECD. Organochlorine pesticides mean concentrations along the River Nile water samples were 0.403, 1.081, 1.209, 3.22, and 1.192 μg L -1 for endrin, dieldrin, p, p'-DDD, p, p'-DDT, and p, p'-DDE, respectively. Dieldrin, p, p'-DDT, and p, p'-DDE were above the standard guidelines of the World Health Organization. Detected organophosphorus pesticides were Triazophos (2.601 μg L -1 ), Quinalphos (1.91 μg L -1 ), fenitrothion (1.222 μg L -1 ), Ethoprophos (1.076 μg L -1 ), chlorpyrifos (0.578 μg L -1 ), ethion (0.263 μg L -1 ), Fenamiphos (0.111 μg L -1 ), and pirimiphos-methyl (0.04 μg L -1 ). Toxicity characterization of organophosphorus pesticides according to water quality guidelines indicated the hazardous risk of detected chemicals to the public and to the different environmental compartments. The spatial distribution patterns of detected pesticides reflected the reverse relationship between regional temperature and organochlorine pesticides distribution. However, organophosphorus was distributed according to the local inputs of pollutant compounds. Toxicological and water quality standards data revealed the hazardous risk of detected pesticides in the Egyptian River Nile water to human and aquatic life. Thus, our monitoring data will provide viewpoints by which stricter legislation and regulatory controls can be admitted to avoid River Nile pesticide water pollution.

    This work deals with the protection of groundwater resources against accidental and agricultural pollutions. It comprises three parts: part 1 is a bibliographic analysis of pollutants transfer mechanisms in the non-saturated zone. It presents the techniques of numerical resolution of the equations controlling these transfers (mechanistic approach). Approaches of data processing-type are also presented. The advantage of neural networks, more and more used in the environmental domain, is emphasized. The second part treats of the migration of non-miscible pollutants (of hydrocarbon or chlorinated solvent type) in the non-saturated zone from an accidental pollution source (a road accident). After a bibliographic analysis of the reference accident, of the most often road transported pollutants and of the available softwares, the area under study is presented with the tests performed at the laboratory for the determination of the permeability coefficient at saturation and the Van Genuchten parameters of the covering layer. The results of the parametric study are given for a reference example using the NAPL-Simulator code. This study allows to outline the main parameters which are used for the construction of a database for the calibration of the neural network-based model. This model is used in the case of the impact study of the road works between Avesnes-sur-Helpes and Maubeuge carried out on the captation fields of Bachant syncline. The third part treats of the migration of a diffuse pollution of agricultural origin (nitrates) in the non-saturated zone. The area under study is presented with the in-situ follow up results of surface fertilizer supplies and of nitrate profile measurements performed for some logging. The construction of the database is detailed. The input data retained are the surface nitrogen supplies, the thickness of the soil beneath the root zone, the water table depth and the time. Finally, the artificial neural networks model and its application to

    Full Text Available Traffic on rivers and lakes in Europe has been ve1y well developed.The reason for this is the transport cost, relative speedand good connectivity of major European cities by rivers andcanals. In Croatia, this transport mode is lagging behind therest of Europe. Croatia is located at an interesting section of theriver transversal, but due to several reasons, river navigation inCroatia has not been developed to any major extent. As operatingriver ships the most frequent types are: towboats, pushboatsand self-propelled ships. The installed diesel engines, propulsionand auxiliary engines run at high power. Proportional tothe increase in the power of installed engines is also the increasein the volume of waste produced by the engines. Also, the olderthe engine, the greater volume of waste it produces. Ships mayalso cause pollution by wastewaters and garbage. This pollutionthreat grows with the greater number of people on boardand the age of the ship. In order to minimize these possibilitiesof pollution, it is necesswy to control all the time the properfunctioning of the ships, train the staff and construct receptionfacilities on land.

    The aim of this article consists of developing an ecosystemic approach to collect information about groundwater pollution in order to determine its origin and infer the health risks in Mingoa's watershed through the study of 12 spontaneous settlements. From an environmental point of view, family interviews and direct observations allowed us to inventory springs, wells and latrines, and to collect information. So, we have selected, on the basis of predefined criteria, 21 wells and springs for physico-chemical and bacteriological laboratory analyses. Two hundred children aged less than 5 years were subjected to KOAP examination. A number of 1224 latrines were inventoried, for an average use of 15 people per latrine, producing 913.3 kg/year of excreta. Most of 91% of people use these latrines. The superficial aquifers, connected to the wells and springs, present high values of nitrogen, phosphorous pollutant and fecal contamination indicators (coliforms and fecal streptococcus), which make water inappropriate to human consumption. PCA analysis establishes that water pollution comes mainly from traditional pit latrines. The overall prevalence of diarrhea and parasite infestation was important (=40%). The presence of cysts of Entamoeba histolytica, Ascaris limbricoides, and Entamoeba coli confirms this high prevalence and testify to very approximate hygiene and environment conditions.

    Methods for evaluating the quantity of water pollutants generated from nonpoint sources including agriculture, silviculture, construction, mining, runoff from urban areas and rural roads, and terrestrial disposal are developed and compiled for use in water quality planning. The loading functions, plus in some instances emission values, permit calculation of nonpoint source pollutants from available data and information. Natural background was considered to be a source and loading functions were presented to estimate natural or background loads of pollutants. Loading functions/values are presented for average conditions, i.e., annual average loads expressed as metric tons/hectare/year (tons/acre/year). Procedures for estimating seasonal or 30-day maximum and minimum loads are also presented. In addition, a wide variety of required data inputs to loading functions, and delineation of sources of additional information are included in the report. The report also presents an evaluation of limitations and constraints of various methodologies which will enable the user to employ the functions realistically

    Full Text Available Ten polychlorinated biphenyl (PCB congeners were determined in water samples collected along the River Nile using gas chromatography-electron capture detector (GC-ECD. PCB concentrations ranged from 14 to 20 μg/L, which were higher than those reported in previous studies, indicating serious PCB pollution in the River Nile. PCB congener profiles varied depending on the sampling sties. PCB-138 was the predominant congener accounting for more than 18% of total PCBs. The composition of PCB congeners in the water revealed that highly chlorinated PCB technical mixtures such as Aroclor 1254 was the main PCB production historically used in Egypt. An increasing trend in PCB levels from the upper stream to the Nile estuaries was observed. The calculated flux of PCBs indicated that 6.8 tons of PCBs is dumped into the Mediterranean Sea each year from the River Nile. The hazard quotients and carcinogenic risk caused by PCB pollution in the River Nile were above the acceptable level indicating that PCBs in the River Nile water pose adverse health effects for all age groups. Our findings revealed that PCBs possess a serious risk to the Egyptian population that depends mainly on the River Nile as a source of water. Thus, stricter legislation and regulatory controls should be applied to reduce the risk of PCBs in Egypt.

    Full Text Available Water often moves us to wonder, joy, terror or peace, and many times, water moves us to prayer. On the other hand, it is projected that, because of water shortages, by 2020, several African countries will experience a 50% reduction in crop yields. Between 75 and 250 million Africans will confront freshwater shortages. Water plays an important role in baptism: the requirements of Christian baptism are the use of water and calling upon the name of the Triune God. Baptism as a water bath is the fulfilment of the Old Testament washings. Nobody could and still can appear before God as an unclean person; baptism stresses the importance of cleansing. The research question that is discussed in this article is the following: in what way may baptism, as holy sign and seal of the washing away of sins by the blood and Spirit of Jesus Christ, contribute to sensitise believers to combat waste in our rivers and dams and the pollution of our waters? Two aspects of baptism are discussed, namely cleansing and going under and coming up from the water as sign and seal of partaking in Christ’s death and resurrection.

    During both the construction and the deposition phase of the final repository, several kinds of polluted waters will occur that must be handled. The waters under consideration in this report are (1) sanitary wastewater, (2) drainage water from the repository, (3) leachate from the rock stockpile and (4) storm water. The aim of this report has been to produce an overview of the different flows of polluted waters and their properties, as well as to propose adequate strategies for their treatment. The report is part of SKB's environmental impact assessment work, but is also meant to be a usable tool in further planning. The sanitary wastewater clearly is the polluted water that possesses the greatest potential risk to human health and the environment. On the other hand it is fully treatable, which means that nuisance and negative environmental impact can be avoided. It is during the construction phase that the largest amounts of both water and pollutants are to be expected. Therefore, the prevailing conditions during construction phase are proposed to be used for dimensioning of technical solutions as well as for environmental impact assessments. The study of different techniques for treatment of sanitary wastewater has included a method called 'open wastewater planning'. The method helps its users to consider the local physical conditions and the prerequisites of the planned activities, as well as the legislative, practical and economical demands. The work comprises three different technical solutions that have been outlined on system level, all of which responds to the national environmental legislation as well as what has been considered as reasonable practical and economical demands. Before the final decision is made, it is recommended that the alternatives are evaluated from a broad perspective by SKB, taking into consideration the value of recycling and goodwill. Discharged leachate from the rock stockpile is expected to contain the greatest amount of nitrogen

  17. Environmental and risk screening for prioritizing pollution prevention opportunities in the U.S. printed wiring board manufacturing industry.

    2011-05-15

    Modern manufacturing of printed wiring boards (PWBs) involves extensive use of various hazardous chemicals in different manufacturing steps such as board preparation, circuit design transfer, etching and plating processes. Two complementary environmental screening methods developed by the U.S. EPA, namely: (i) the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) and (ii) Risk-Screening Environmental Indicators (RSEI), are used to quantify geographic and chemical environmental impacts in the U.S. PWB manufacturing industry based on Toxics Release Inventory (TRI) data. Although the release weight percentages of industrial chemicals such as methanol, glycol ethers and dimethylformamide comprise the larger fraction of reported air and water emissions, results indicate that lead, copper and their compounds' releases correspond to the highest environmental impact from toxicity potentials and risk-screening scores. Combining these results with further knowledge of PWB manufacturing, select alternative chemical processes and materials for pollution prevention are discussed. Examples of effective pollution prevention options in the PWB industry include spent etchant recovery technologies, and process and material substitutions. In addition, geographic assessment of environmental burden highlights states where promotion of pollution prevention strategies and emissions regulations can have the greatest effect to curb the PWB industry's toxic release impacts.

    Corrosion may be defined as a naturally occurring physical and chemical deterioration of a material due to reaction with the environment or surrounding atmosphere. In boilers the material is subjected on both sides to two different media which may cause severe corrosion. At the water side the content of O 2 considered one of the principal factors which determine the extent of corrosion in the boiler tubes. This paper deals with certain conditions that result in the increase of O 2 in the boiler water and hence increase the corrosion rate, to minimize the effect of these conditions a chemical treatment was carried out the results obtained indicated the success of the treatment procedure in corrosion prevention and boiler material protection. The treatment is traditional. But the study indicates how a simple mean could be applied to solve a serious problem. 4 tab

    This paper presents a system for determining the evaluation and gradation indices of groundwater pollution intensity (GPI). Considering the characteristics of the vadose zone and pollution sources, the system decides which anti-seepage measures should be implemented at the contaminated site. The pollution sources hazards (PSH) and groundwater intrinsic vulnerability (GIV) are graded by the revised Nemerow Pollution Index and an improved DRTAS model, respectively. GPI is evaluated and graded by a double-sided multi-factor coupling model, which is constructed by the matrix method. The contaminated sites are categorized as prior, ordinary, or common sites. From the GPI results, we develop guiding principles for preventing and removing pollution sources, procedural interruption and remediation, and end treatment and monitoring. Thus, we can select appropriate prevention and control technologies (PCT). To screen the technological schemes and optimize the traditional analytical hierarchy process (AHP), we adopt the technique for order preference by the similarity to ideal solution (TOPSIS) method. Our GPI approach and PCT screening are applied to three types of pollution sites: the refuse dump of a rare earth mine development project (a potential pollution source), a chromium slag dump, and a landfill (existing pollution sources). These three sites are identified as ordinary, prior, and ordinary sites, respectively. The anti-seepage materials at the refuse dump should perform as effectively as a 1.5-m-thick clay bed. The chromium slag dump should be preferentially treated by soil flushing and in situ chemical remediation. The landfill should be treated by natural attenuation technology. The proposed PCT screening approach was compared with conventional screening methods results at the three sites and proved feasible and effective. The proposed method can provide technical support for the monitoring and management of groundwater pollution in China. - Highlights: • An

    The continuous liquid-liquid, CLLE, and solid-phase, SPE. extraction techniques were used to study a problem of international relevance. The work was incident on the evaluation of the efficiency and optimisation of extruding techniques, CLLE. SPE and CLLEt-SPE, towards chlorinated pesticides and phenolic compounds from the Giza treatment plant station (Egypt), where the degree of pollution of such substances in drinking waters must be reduced. The total recoveries, rs, using SPE ranged between I).74 -0.87, whereas, the values were much less using the other two methods (0.158 - 0.1961; indicating the preferability of the SF'E technique. Analytical results were obtained through the various chromatographic techniques, liquid or gas. with adequately chosen detectors. A simple mathematical algorithm has been empirically developed allowing the assessment and comparison of the efficiencies of the three extracting procedures. Further treatment with ozone resulted in the oxidation and elimination of organic pollutants, with consequent improvement of water quality (total pesticide content 0.332-0.19μgL -1 ). A useful ozone treatment unit, capable of dealing with the emanation of contaminants in tap water, was built

  8. New Photocatalysis for Effective Degradation of Organic Pollutants in Water

    2009-12-01

    The presence of harmful compounds in water supplies and in the discharge of wastewater from chemical industries, power plants, and agricultural sources is a topic of global concern. The processes and technologies available at the present time for the treatment of polluted water are varied that include traditional water treatment processes such as biological, thermal and chemical treatment. All these water treatment processes, have limitations of their own and none is cost effective. Advanced oxidation processes have been proposed as an alternative for the treatment of this kind of wastewater. Heterogeneous photocatalysis has recently emerged as an efficient method for purifying water. TiO2 has generally been demonstrated to be the most active semiconductor material for decontamination water. One significant factor is the cost of separation TiO2, which is generally a powder having a very small particle size from the water after treatment by either sedimentation or ultrafiltration. The new photocatalyst, HTiNbO5, has been tested to determine whether its photocatalytic efficiency is good enough for use in photocatalytic water purification since it has high surface area and relatively large particle size. The larger particle sizes of the porous materials facilitate catalyst removal from a solution, after purification has taken place. It can be separated from water easily than TiO2, a significant technical improvement that might eliminate the tedious final filtration necessary with a slurry. These materials are characterized and tested as water decontamination photocatalysts. The new catalyst exhibited excellent catalytic activity, but with a strong pH dependence on the photo efficiency. These results suggest that elimination of the ion exchange character of the catalyst may greatly improve its performance at various pHs. This new research proposes to study the effects of a topotactic dehydration reaction on these new porous material catalysts.

    The pollution of tap water and rain water with formaldehyde in Toyama Pref., Japan was investigated by means of a simple, rapid and cost-effective visual colorimetry developed by us. The levels of formaldehyde in three tap waters from different sources of dams on mountainside and a well-water pumped in urban area in Toyama Pref. were lower than 0.01 mg L(-1) that was the detection limit of the colorimetry. On the other hand, rain waters were seriously polluted with formaldehyde. Rain waters were sampled from three different sites (urban area, top of hill and industrial area) in Toyama Pref. from autumn to winter in 2006. The levels of formaldehyde in the rain waters ranged from 0.07 to 0.30 mg L(-1). The analytical results by the visual colorimetry were in good agreement with those obtained by GC-MS method. It was confirmed that the colorimetry is excellent for practical use for the determination of formaldehyde. It must be concerned about the pollution of rainwater with formaldehyde, when rain water is applied for tap water and miscellaneous purpose. Copyright IWA Publishing 2008.

    Sensitized-photochemical oxidation methods aimed at use in water treatment technologies for deactivation of biotic (microorganisms) and/or of xenobiotic (pesticides) pollutants in water were developed using global solar radiation or concentrated sunlight (up to 250 suns). The solar global radiation was used either for detoxification of industrial waste water from a pesticide factory to allow their discharge into the urban sewer, or for disinfection of domestric effluents to be used in crop irrigation. The disinfection process was eventually carried out in an experimental pilot-scale plant, capable of disinfection up to 50 m{sup 3}/h of effluent supplied by an activated sludge sewage treatment plant located in Tel-Aviv area. The treated effluents did not show any regrowth of the microorganisms during 7 days. The solar concentrated radiation experiments performed using facilities of the Sun Tower of The Weizman Institute of Science, Rehovot. The concentrated sunlight was provided by different combination of several computer controlled heliostates, up to 8, that track the sun and focus the received sunlight onto the target situated on the roof of the sun-tower. The sunlight intensities measured on the target reached up to 200 kW/m{sup 2}. The experiments were performed either batch- or continuous-wise. The water-samples exposed to disinfection were the above effluent, filtered and supplemented with vaccine strain poliovirus or with different concentrations of an industrial potential pollutant (bromacil), MB 2 mg/L and two concentrations of dissolved oxygen (8.0 or 40.0 mg O{sub 2}/L). An exposure time of 2-3 seconds at 150 kW/m{sup 2} was decreased the microorganisms alive (counts) by five orders of magnitude. A comparison between the two above water treatment technologies is presented. (orig./SR)

  13. Pollution prevention and control procedure case study: an application for petroleum refineries.

    Rodríguez, Encarnación; Martínez, Jose-Luis

    2005-06-01

    There is global environmental concern about the pollution from industries and other organizations that should not only be controlled but also prevented. Many alternatives are available to those in charge of environmental protection, but they should be able to draw on a systematic procedure to help implement prevention and control measures. At present, there are three immediate tasks: defining the objective of any environmental study, identifying the potential pollution sources, and selecting alternatives to these sources. However, it is necessary to evaluate these alternatives by using as large a number of criteria as possible and making them cumulative so as to enable the classification and selection of the best available techniques for each pollution source. The petroleum refining industry plays an important role in the developed economies and also has a potential for pollution generation that must be controlled. The best solution for all (i.e., petroleum companies, the public, and the environment) is pollution prevention, because this option will protect all of them and will also reduce costs in terms of lower raw materials consumption as well as reducing potential fines. The procedure we have presented in this article has been applied successfully.

    Chaj Doab is an interfluvial tract of land bounded by the rivers Chenab and Jhelum. Agriculture is the main economic activity in the area. In order to increase crop production,. natural and industrial fertilizers are excessively used. Shallow groundwater is the main source of water for domestic and agricultural usage. Nitrate in the soil is carried to the groundwater by precolating water. Concentration of nitrate in groundwater which used to be less than 3 mg/l has crossed the WHO limit of 45 mg/l at several places principally due to the excessive use of fertilizers. In order to avoid serious consequences of nitrate pollution of groundwater, application of fertilizers will have to be judiciously practiced. (author)

    Full Text Available Creation of rain sewer is connected with dehydration of roads and coexisting objects. The paper presents a discussion upon the issue of groundwater contamination by petroleum compounds and other pollutants from transport based on studies of groundwater within the parking lots. The study included 9 parking areas, including 7 in Bialystok, 1 in a residential area outside of Bialystok in Ignatki, and one in Kleosin. The tested waters were subject to determination of COD, total suspension, and petroleum substances expressed as a mineral oil index. The studies have shown that the concentrations of determined parameters were in most cases proportional to the larger runoffs and concentration of petroleum compounds increased with the increase of suspension. It has been shown that from part of the parking lots, the meteoric water was discharged directly into watercourses and exceeds the permissible limits regulated by the Decree.

  20. Oak Ridge K-25 Site chlorinated solvent pollution prevention opportunity assessment

    International Nuclear Information System (INIS)

    1994-08-01

    A pollution prevention opportunity assessment (PPOA) was conducted at the Oak Ridge K-25 Site to identify opportunities to reduce and better manage the use of chlorinated solvents. At the K-25 Site, 67 control areas were examined for their potential use of chlorinated solvents. Of these areas, 27 were found to be using (1) chlorinated solvents for cleaning, degreasing, and lubricating; (2) laboratory standards and solvents; and (3) test medium. Current management practices encourage the identification and use of nonhazardous chemicals, including the use of chlorinated solvents. The main pollution prevention principles are source reduction and recycling, and a number of pollution prevention options based on these principles were identified and evaluated as part of this chlorinated solvent PPOA. Source reduction options evaluated for the K-25 Site include the substitution of chlorinated solvents with nonchlorinated solvents. Recycling was identified for those areas that would benefit most from the reuse of the chlorinated solvents in use. The pollution prevention options that offer the greatest opportunity for success at the K-25 Site are the implementation of substitutes at the 10 control areas using chlorinated solvents for cleaning, degreasing, and lubrication. A change in the process may be all that is needed to eliminate the use of a chlorinated solvent. Once a decision is made to implement a substitution, the information should be communicated to all shops and laboratories. Another option to consider is the installation of recycling units to recycle the large amounts of methylene chloride used in the analytical sampling procedure

  5. Environmental Restoration Program pollution prevention performance measures for FY 1993 and 1994 remedial investigations

    International Nuclear Information System (INIS)

    1993-03-01

    The Martin Marietta Energy Systems, Inc., Environmental Restoration (ER) Program adopted a Pollution Prevention Program in March 1991. The program's mission is to minimize waste and prevent pollution in remedial investigations (RI), feasibility studies (FS), decontamination and decommissioning (D ampersand D), and surveillance and maintenance (S ampersand M) site program activities. Mission success will result in volume and/or toxicity reduction of generated waste. Energy Systems is producing a fully developed a Numerical Scoring System (NSS) and actually scoring the generators of Investigation Derived Waste (IDW) at six ER sites: Oak Ridge National Laboratory (ORNL), the Oak Ridge Y-12 Plant, the Oak Ridge K-25 site, Paducah Gaseous Diffusion Plant (Paducah), and Portsmouth Uranium Enrichment Complex (Portsmouth). This report summarizes the findings of this initial numerical scoring evaluation and shows where improvements in the overall ER Pollution prevention program may be required. This report identifies a number of recommendations that, if implemented, would help to improve site-performance measures. The continued development of the NSS will support generators in maximizing their Pollution Prevention/Waste Minimization efforts. Further refinements of the NSS, as applicable suggest comments and/or recommendations for improvement

  6. Special issue review of pollution prevention management within the Department of Energy, final report

    International Nuclear Information System (INIS)

    1994-08-01

    The Department of Energy's (DOE) national role and overall mission has been undergoing significant change. In the post-Cold War era, a new emphasis on cleaning up the wastes from the past has emerged. These changes provide both significant challenges as well as new opportunities for DOE. While the challenges may seem overwhelming as DOE realizes the magnitude of its environmental problems, its network of national laboratories and sites provide the resources to become a leader in environmental management through the development of new technologies and management practices. Because of the growing importance of pollution prevention in the United States and more specifically to DOE's environmental management strategy, the Office of Environmental Audit (EH-24) identified this as an area worthy of a Special Issue Review. A Special Issue Review is not an audit but rather an in-depth review of key environmental programs or activities which cut across organizational boundaries. The purpose of a Special Issue Review is to identify strengths and weaknesses of a program as well as significant crosscutting issues or challenges that are important to the future success of that program. The scope of the review included an assessment of pollution prevention program activities at Headquarters, selected operations offices, and selected sites offices and contractor organizations. All aspects of a pollution prevention program were considered including program strategy, infrastructure, management systems, and implementation practices. Also summarized are future pollution prevention challenges and recommendations

    A method has been developed and tested for PIXE analysis of soluble and insoluble constituents in a variety of water samples in our surroundings. Insoluble components were filtered on a Nuclepore filter of 0.4-{mu}m pores. For soluble fractions, a target of major components was made from a 0.15-ml filtrate evaporated on a user-made polycarbonate film, and in turn heavy metals in trace amounts were preconcentrated in a PIXE-target through the use of a combination of dibenzyldithiocarbamate-chelation with subsequent condensation into dibenzylidene-D-sorbitol gels. These three kinds of targets were analyzed with a PIXE system of 3-MeV proton beams. The widespread concentrations (several tenths of ppb to a few tens of ppm) of {approx}24 elements from Na to Pb were determined simultaneously in a precision sufficient to reveal the elemental distribution between the soluble and insoluble fractions of various aqueous sample such as river water, rain water and water leaking from disposal sites of industrial wastes. Hence, the methodology for preparing three types of targets promotes the PIXE analysis to a truly effective means for monitoring a water-pollution problem in our surroundings. (author)

    2007-05-01

    During both the construction and the deposition phase of the final repository, several kinds of polluted waters will occur that must be handled. The waters under consideration in this report are (1) sanitary wastewater, (2) drainage water from the repository, (3) leachate from the rock stockpile and (4) storm water. The aim of this report has been to produce an overview of the different flows of polluted waters and their properties, as well as to propose adequate strategies for their treatment. Several different alternatives of action have been investigated and compared in terms of environmental impact, economy and technical aspects. The report is part of SKB's environmental impact assessment work, but is also meant to be a usable tool in further planning. It is during the construction phase that the largest amounts of both water and pollutants are to be expected. Therefore, the conditions during the construction phase are proposed to be used for dimensioning of technical solutions as well as for environmental impact assessments. The study of different techniques for treatment of sanitary wastewater has included a method called 'open wastewater planning'. The work comprises six different technical solutions that have been outlined on system level, all of which responds to the national environmental legislation, as well as what has been considered as reasonable practical and economical demands. A urine diverting system combined with a local system for treatment of wastewater has been found to be the most interesting solution. The least attractive alternative in relation to the claimed demands is a traditional system for mixed wastewater connected to the existing wastewater treatment plant at the Oskarshamn nuclear power plant. This is mostly due to the high estimated cost for the connection pipe. Discharged leachate from the rock stockpile is expected to contain the greatest amount of nitrogen, at most 6 tonnes a year. Drainage water from the repository will also

    Multiple free water surface flow constructed wetlands (multi-FWS CWs) are a variety of conventional water treatment plants for the interception of pollutants. This review encapsulated the characteristics and applications in the field of ecological non-point source water pollution control technology. The roles of in-series design and operation parameters (hydraulic residence time, hydraulic load rate, water depth and aspect ratio, composition of influent, and plant species) for performance intensification were also analyzed, which were crucial to achieve sustainable and effective contaminants removal, especially the retention of nutrient. The mechanism study of design and operation parameters for the removal of nitrogen and phosphorus was also highlighted. Conducive perspectives for further research on optimizing its design/operation parameters and advanced technologies of ecological restoration were illustrated to possibly interpret the functions of multi-FWS CWs.

    Marine pollution has now become worldwide environmental concern. Continuous discharge of untreated industrial effluent, municipal and power plant contaminated wastewater has been a serious threat to marine habitat, aesthetic values and interest of visitors to coastal areas. Karachi is the largest city of Pakistan and industrial hub of the Arabian Sea. In this investigation, samples of sediment, water, flora and fauna were taken from nine selected stations on Karachi coast included three stations represented major creeks i.e. Korangi, Gizri and Chinna Creek. These samples were taken during north-east and south-west monsoonal period in 2014. Bacterial flora isolated and identified from samples collected from these sites by conventional method. Among isolated and identified bacteria e.g. Vibrio alginolyticus, Escherichia coli and Streptococuss anginosus were the most dominant species contributing 21.43, 19.64 and 15.18 percent of total assemblage respectively. Among selected sample stations, Korangi creek station was found to be most polluted with coliform and other pathogenic bacteria. These results clearly indicate that threats from these pathogens are not only to marine life but also to the large number of visitors coming to beaches and residents of surrounding area. Moreover; immediate action should be taken to restrict the growth of these pathogens by taking measures to treat the municipal and industrial effluent to avoid outbreak of any disease in future.

    In recent years, the international community has witnessed incidence of climate variability and human activities. The objective of this paper is protecting water resources from pollution in the catchments area of Lake Badovc. The catchments area of the Lake Badovc has a size of 109 km² and the active storage volume of the lake is assessed to 26.4 Mill.m3. Around 28% of the total population of Municipality of Prishtina supply with drinking water from Lake Badovc. The hydrologic modelling system used, is HEC-HMS developed by the Hydrologic Engineering Centre of the US Corps of Engineers. The model is designed to simulate the rainfall-runoff processes of catchments areas and is applicable to a wide range of geographic areas.Water samples are taken from two streams reach Lake Badovc and from the lake in three different depths (5m, 10m and 15m) at different locations. Concerning the environment impact more than 140 interviews were conducted and questionnaires filled in the period October-November for Mramor area, concentrating on the most important issues: building, water supply, wastewater disposal and west disposal.

    Air pollution, global warming and climate change are the major contributing factors in causing the increase prevalence of allergic airway diseases like asthma and allergic rhinitis and they will be the defining issues for health system in the twenty-first century. Asthma is an early onset non-communicable environmental disease with global epidemic and contributes a greatest psycho socio economic burden. Nearly 8 million global deaths are from air pollution. Over one billion population are the sufferers during 2015 and will increase to 4 billion by 2050. Air pollution not only triggers the asthma episodes but also changes the genetic pattern in initiating the disease process. Over the years our concept of management of allergic airway disease has changed from control of symptoms to prevention of the disease. To achieve this we need positive development on clean air policies with standard norms, tracking progress, monitoring and evaluation, partnership and conventions with local and global authorities. We do have challenges to overcome like rapid urbanization, lack of multisectorial policy making, lack of finance for research and development and lack of monitoring exposure to health burden from air pollution. We need to prioritize our strategy by sustainable, safe, human settlement, cities, sustainable energy, industrialization, and research. The measures to be adopted are highlighted in this review article. With effective measures by all stake holders we can reduce air pollution and prevent the global warming by 2030, along with 194 countries as adopted by WHO in May 2015.

    Boron isotopic systematics as related to ground-water pollution is reviewed. We report isotopic results of contaminated ground water from the coastal aquifers of the Mediterranean in Israel, Cornia River in north-western Italy, and Salinas Valley, California. In addition, the B isotopic composition of synthetic B compounds used for detergents and fertilizers was investigated. Isotopic analyses were carried out by negative thermal ionization mass spectrometry. The investigated ground water revealed different contamination sources; underlying saline water of a marine origin in saline plumes in the Mediterranean coastal aquifer of Israel (δ 11 B=31.7 per mille to 49.9 per mille, B/Cl ratio ∼1.5x10 -3 ), mixing of fresh and sea water (25 per mille to 38 per mille, B/Cl∼7x10 -3 ) in saline water associated with salt-water intrusion to Salinas Valley, California, and a hydrothermal contribution (high B/Cl of ∼0.03, δ 11 B=2.4 per mille to 9.3 per mille) in ground water from Cornia River, Italy. The δ 11 B values of synthetic Na-borate products (-0.4 per mille to 7.5 per mille) overlap with those of natural Na-borate minerals (-0.9 per mille to 10.2 per mille). In contrast, the δ 11 B values of synthetic Ca-borate and Na/Ca borate products are significantly lower (-15 per mille to -12.1 per mille) and overlap with those of the natural Ca-borate minerals. We suggest that the original isotopic signature of the natural borate minerals is not modified during the manufacturing process of the synthetic products, and it is controlled by the crystal chemistry of borate minerals. The B concentrations in pristine ground-waters are generally low ( 11 B=39 per mille), salt-water intrusion and marine-derived brines (40 per mille to 60 per mille) are sharply different from hydrothermal fluids (δ 11 B=10 per mille to 10 per mille) and anthropogenic sources (sewage effluent: δ 11 B=0 per mille to 10 per mille; boron-fertilizer: δ 11 B=-15 per mille to 7 per mille). some

    On-site sanitation provisions in urban slums rarely prioritise grey water management, yet it forms the largest fraction of wastewater. This study was carried out to characterise grey water and quantify its pollutant loads in Bwaise III (Uganda) and to provide data for grey water management in urban slums of developing countries. Samples were collected for analysis from ten representative households as well as from four tertiary drains and the main drainage channel for 7 months in two dry seasons. Grey water production was found to comprise 85 % of the domestic water consumption. The chemical oxygen demand concentration in the grey water generated by laundry, in the kitchen and in the bathroom was 9,225 ± 1,200 mg L-1, 71,250 ± 1,011 mg L-1 and 4,675 ± 750 mg L-1, while the BOD5 (biochemical oxygen demand) to COD ratio was 0.24 ± 0.05, 0.33 ± 0.08 and 0.31 ± 0.07, respectively. The maximum concentration of Escherichia coli and total coliforms was 2.05 9 107 cfu (100 mL)-1 and 1.75 9 108 cfu (100 mL)-1, respectively, in grey water from the bathroom, while that of Salmonella spp. was 7.32 9 106 cfu (100 mL)-1 from laundry. Analysis of variance (ANOVA) showed a significant difference in the concentration of COD, total suspended solids, total organic carbon, dissolved organic carbon, total phosphorus, sodium adsorption ratio, oil and grease, and Salmonella spp. in grey water from laundry, bathroom and kitchen (p/0.05). The high loads of COD ([500 kg day-1), total suspended solids ([200 kg day-1), nutrients (8.3 kg TKN day-1 and 1.4 kg total phosphorus day-1) and microorganisms (106 to 109 cfu c-1 day-1) originating from grey water in Bwaise III show that grey water poses a threat to the environment and a risk to human health in urban slums. Therefore, there is a need to prioritise grey water treatment in urban slums of developing countries to achieve adequate sanitation.

    M.Sc. The removal of organic pollutants from industrial and municipal water is a great challenge to water providers worldwide. Some of these pollutants are very toxic and pose serious health risks to both humans and animals. Additionally, the presence of organic pollutants in the water often leads to the corrosion of turbines used for power generation at power stations. This obviously makes the power generation process less efficient and thus has cost implications, especially for the end u...

    2009-01-01

    The objective of this study is the estimation of the polluting load generated by domestic effluents added to those of various industries in one of the most important industrial zone in Africa. Analysis of waste water showed strong and irregular pollution which is prejudicial for the aquatic receiving medium (river, sea). This pollution is confirmed among others by COD/BOD ratio which may attain the value of 1.8. Pre-treatment by coagulation floculation of waste water used in a dairy belonging to this industrial zone showed a considerable reduction of the initial pollution by a systematic decreasing of pollution parameters. Aluminium sulphates and iron chloride tested in this experience have reduced considerably all the studied parameters; the organic charge has received a very significant reduction up to 99%. The discharge of treated effluent in the surrounding river or its use for recycling aims is then possible for this industry. However, the formed sludge can be the subject of a suitable treatment for possible agricultural, avicolous valorisation or other. (author)

  20. Status of water pollution in relation to industrialization in Rajasthan.

    2017-09-26

    India is a large and densely populated country; its economy is largely agricultural. Making the best use of the country's manpower has always posed a challenge. Industrialization could become a dominant component of the economy and displace agriculture. Traditional livelihoods of occupational groups are threatened by the practice of disposing untreated industrial waste into rivers and bodies of water. These uncontrolled disposals impact local natural resources with negative long-term effects. Industrialization is the development of intellectual and financial trade that changes a predominantly rustic culture into a modern one. Many industrial units discharge wastewater locally without treatment. Many industries directly discharged their waste into lakes, rivers and ocean. Water contamination impacts the environment. Pesticides, chemical, waste oil and heavy metals are regularly transported into their waters. Humans and other living organisms can accumulate heavy metals from industrial discharges in their tissues. Industrial waste may be reactive, corrosive, flammable, or toxic. When untreated sewage is emptied into rivers, it causes diseases like typhoid, dysentery and cholera. Natural elements and plant supplements like nitrate and phosphates stimulate growth of algae on the water surface. The algae reduce the oxygen in the water and cause eutrophication. It is harmful to the water ecosystem. In Rajasthan proper, there are a number of sites bordering rivers and lakes where the pace of industrialization has proceeded far beyond the ability of regulators to establish and enforce meaningful limits on the amount of point source pollution permitted to the various industrial complexes, which include cement, chemical, fertilizer, textile, mining, quarrying, dyeing and printing facilities. The scale of the problem is obvious to the casual observer, but actual documentation of the total impact remains to be done.

    Ampong, Charles Horace

    1993-11-01

    Prestea is a mining community developed around Prestea Goldfields Limited, which is engaged in mining Sulphide gold ores known to give rise to several environmental problems like air pollution in the form of emissions of arsenic or arsenous oxides, with concurrent production of large amounts of Sulphur dioxide. As a result of extensive mining since 1929 using underground methods, involving about 18 million tons of ore, an estimated 3.5 - 4 million tons of tailings have been left on the surface in the vicinity of both current and historic treatment sites. Since the mine is located in an area of heavy rainfall, incessant rain will flush contaminants from tailings dumps and waste sites into the downstream environment and subsequently into surface waters. Water supply for the population in the area is derived from rivers and streams flowing in the area, supplemented by boreholes and spring water. Not much is known with respect to pollution levels along the rivers and streams which serve as water for domestic uses by settlers along these river banks and around. It therefore became necessary to carry out studies to ascertain the pollution levels of various water resources and to make some suggestions to guide pollution of these waters and uses of them as well. Water sampling was carried out in the rivers and streams. A spring water and well water were also sampled as reference data to ascertain background levels of pollutants. The work highlights activities of the mine and that of the surrounding inhabitants which are likely to result in the pollution of surface waters. It also discusses results of water samples within the area, Sample analysis included determination of parameters like pH, Temperature, Conductivity, Alkalinity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Solids (TS), Total hardness, Cyanide and Sulphate concentrations among others. Concentrations of some heavy metals were also determined. Based on standards prevailing in the country

    Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temporal variations and the latent sources of water pollution in the Shanchong River basin, Northwest Basin of Lake Fuxian, China. We group all field surveys into 2 clusters (dry season and rainy season). Moreover, 14 sampling sites have been grouped into 3 clusters for the rainy season (highly polluted, moderately polluted and less polluted sites) and 2 clusters for the dry season (highly polluted and less polluted sites) based on their similarities and the level of pollution during the two seasons. The results show that the main trend of pollution was aggravated during the transition from the dry to the rainy season. The Water Pollution Index of Total Nitrogen is the highest of all pollution parameters, whereas the Chemical Oxygen Demand (Chromium) is the lowest. Our results also show that the main sources of pollution are farming activities alongside the Shanchong River, soil erosion and fish culture at Shanchong River reservoir area and domestic sewage from scattered rural residential area. Our results suggest that strategies to prevent water pollutionat the Shanchong River basin need to focus on non-point pollution control by employing appropriate fertilizer formulas in farming, and take the measures of soil and water conservation at Shanchong reservoir area, and purifying sewage from scattered villages.

    Characteristics of dispersion and diffusion as the mechanisms by which pollutants are transported in natural river courses were studied with the view of providing additional data for the establishment of water quality guidelines and effluent outfall design protocols. Work has been divided into four basic categories which are directed at the basic goal of developing relationships which will permit the estimation of the nature and extent of the mixing zone as a function of those variables which characterize the outfall structure, the effluent, and the river, as well as climatological conditions. The four basic categories of effort are: (1) the development of mathematical models; (2) laboratory studies of physical models; (3) field surveys involving ground and aerial sensing; and (4) correlation between aerial photographic imagery and mixing zone characteristics.

    Rice husks, a locally available agricultural by-product, were investigated with aim of producing good adsorbing materials suitable for remediating water pollution . Raw lignocellulose was treated through various procedures: simple carbonization to high temperature, pyrolysis under flowing steam at moderate temperatures and chemical activation with H 3 PO 4 followed by pyrolysis at moderate temperature . A partially deashed precursor was obtained by boiling in alkali solution, thereafter botanical residue was steam activated at a single temperature, and leachate acidified whereby silica was precipitated, many types of adsorbents were thus derived: chars, activated carbon and silica. the obtained various categories of sorbents were characterized by different techniques to asses their physico-chemical and adsorptive properties . this involved: ash content, thermogravimetry, FTIR, electron microscopy, N 2 gas adsorption at 77 k and adsorption capacity from solution using probe molecules

    This paper presents the results of an experiment carried out for the first time in situ to select a treatment to devitalize mosses for use in active biomonitoring of water pollution. Three devitalizing treatments for the aquatic moss Fontinalis antipyretica were tested (i.e. oven-drying at 100 °C, oven-drying with a 50-80-100 °C temperature ramp, and boiling in water), and the effects of these on loss of material during exposure of the transplants and on the accumulation of different heavy metals and metalloids were determined. The suitability of using devitalized samples of the terrestrial moss Sphagnum denticulatum to biomonitor aquatic environments was also tested. The structure of mosses was altered in different ways by the devitalizing treatments. Devitalization by boiling water led to significantly less loss of material (p treatments. However, devitalization by oven-drying with a temperature ramp yielded more stable results in relation to both loss of material and accumulation of elements. With the aim of standardizing the moss bag technique, the use of F. antipyretica devitalized by oven-drying with a temperature ramp is recommended, rather than other devitalization treatments or use of S. denticulatum.

    Sources of pollution discharges and water quality samples at 27 stations in 2006 in the coastal waters of Hebei Province, western Bohai Sea, have been analyzed in this study. Pollutant loads from industrial sewages have shown stronger impact on the water environment than those from the general sewages. Analysis indicates that pollution of COD is mainly resulted from land-based point pollutant sources. For phosphate concentration, non-point source pollution from coastal ocean (fishing and harbor areas) plays an important role. To assess the water quality conditions, Organic Pollution Index and Eutrophication Index have been used to quantify the level of water pollution and eutrophication conditions. Results show that pollution was much heavier in the dry season than flood season in 2006. Based on COD and phosphate concentrations, results show that waters near Shahe River, Douhe River, Yanghe River, and Luanhe River were heavily polluted. Water quality in the Qinhuangdao area was better than those in the Tangshan and Cangzhou areas. Copyright © 2011 Elsevier Ltd. All rights reserved.

  13. Macro-invertebrate decline in surface water polluted with imidacloprid.

    Full Text Available Imidacloprid is one of the most widely used insecticides in the world. Its concentration in surface water exceeds the water quality norms in many parts of the Netherlands. Several studies have demonstrated harmful effects of this neonicotinoid to a wide range of non-target species. Therefore we expected that surface water pollution with imidacloprid would negatively impact aquatic ecosystems. Availability of extensive monitoring data on the abundance of aquatic macro-invertebrate species, and on imidacloprid concentrations in surface water in the Netherlands enabled us to test this hypothesis. Our regression analysis showed a significant negative relationship (P<0.001 between macro-invertebrate abundance and imidacloprid concentration for all species pooled. A significant negative relationship was also found for the orders Amphipoda, Basommatophora, Diptera, Ephemeroptera and Isopoda, and for several species separately. The order Odonata had a negative relationship very close to the significance threshold of 0.05 (P = 0.051. However, in accordance with previous research, a positive relationship was found for the order Actinedida. We used the monitoring field data to test whether the existing three water quality norms for imidacloprid in the Netherlands are protective in real conditions. Our data show that macrofauna abundance drops sharply between 13 and 67 ng l(-1. For aquatic ecosystem protection, two of the norms are not protective at all while the strictest norm of 13 ng l(-1 (MTR seems somewhat protective. In addition to the existing experimental evidence on the negative effects of imidacloprid on invertebrate life, our study, based on data from large-scale field monitoring during multiple years, shows that serious concern about the far-reaching consequences of the abundant use of imidacloprid for aquatic ecosystems is justified.

    This report presents a position of the pollutants degradation of the industrial residual waters, it intends a method that consists on making pass residual water, treated biologically by a packed column with activated carbon. The carbon retains the pollutants and the water goes out with a purity that allows the reuse. In simultaneous form to the adsorption of pollutants are made pass electrons through the column of carbon, the electrons will destroy to the polluting adsorbed in the carbon; the pollutants degrade until CO 2 that escapes as gas. The active sites of the carbon are empty and clever to be occupied by other pollutants. This process is continuous and it is repeated while water is passing by the column and electrons through this.
