    A Level II Cultural Resource Survey was completed for the Texoma Distribution Enhancements project, located in Cameron and Calcasieu Parishes, Louisiana. The 13-mile pipeline extends from Strategic Petroleum Reserve No. 3 to a terminus near Vincent Landing. Located in Louisiana's southwest coastal zone, the pipeline will traverse extensive marsh lands as well as upland prairie terrace areas. Present land use within the project area consists primarily of undeveloped marsh land and cattle range. The study methods included background research, intensive pedestrian survey with systematic shovel testing, a boat survey, and laboratory analysis of recovered artifact collections. One historic site, 16CU205, was identified during the field survey, and it was tested for National Register eligibility. The site is assignable to the Industrialization and Modernization (1890-1940) Cultural Unit. Archaeological testing indicates that it is a rural residence or farmstead, with a house and one outbuilding within the proposed right-of-way. The site lacks significant historical association and sufficient archaeological integrity to merit inclusion on the National Register of Historic Places. Four standing structures were also identified during the field survey. The structures are agricultural outbuildings, less than 40 years in age, that possess no architectural distinction or historical association. They have been documented photographically and by scaled plan drawings, but do not merit additional study prior to their destruction. 24 refs., 15 figs., 3 tabs.

  2. Prairie Canal Well No. 1, Calcasieu Parish, Louisiana. Volume 1. Completion and testing. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1981-01-01

    The Prairie Canal Company, Inc. Well No. 1, approximately 8 miles south of the city of Lake Charles, Louisiana, was tested through the annulus between 5-1/2 inch casing and 2-3/8 inch tubing. The interval tested was from 14,782 to 14,820 feet. The geological section was the Hackberry Sand, a member of the Oligocene Frio formation. Produced water was injected into a disposal well which was perforated in several Miocene Sands from 3070 to 4600 feet. Original plans were to test a section of the Hackberry sand from 14,976 to 15,024 feet. This primary zone, however, produced a large amount of sand, shale, gravel, and rocks during early flow periods and was abandoned in favor of the secondary zone. Four pressure drawdown flow tests and three pressure buildup tests were conducted during a 12-day period. A total of 36,505 barrels of water was produced. The highest sustained flow rate was approximately 7100 BWPD. The gas-to-water ratio, measured during testing, ranged from 41 to 50 SCF/BBL. There is disagreement as to the saturation value of the reservoir brine, which may be between 43.3 and 49.7 SCF/BBL. The methane content of the flare line gas averaged 88.4 mole percent. The CO/sub 2/ content averaged 8.4 mole percent. Measured values of H/sub 2/S in the gas were between 12 and 24 ppM.

    Current and historical point source discharges, storm water runoff, and accidental spills have contaminated the water, sediment, and biota within the Calcasieu Estuary in southwestern Louisiana. In 2003, barn swallow (Hirundo rustica) eggs and nestlings were collected beneath two bridges that cross Bayou d'Inde, the most contaminated waterway within the Calcasieu Estuary. Samples were also collected from a bridge over Bayou Teche, a reference site in south central Louisiana. Polychlorinated biphenyl (PCB) concentrations in barn swallow eggs and nestlings were significantly higher at the downstream site on Bayou d'Inde (2.8 mu g/g PCBs in eggs and 1.5 mu g/g PCBs in nestlings) than at the other two sites (nestlings at both sites). Ethoxyresorufin-O-dealkylase activity in nestling livers was significantly higher at the downstream site on Bayou d'Inde (50 pmol/min/mg) compared to the other two locations (24 pmol/min/mg, each), probably because of exposure to PCBs. Polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran concentrations in eggs and polycyclic aromatic hydrocarbons in nestlings were at background concentrations at all sites. Trace element concentrations in barn swallow eggs and nestling livers were at background levels and did not differ among the three sites. A biomarker of DNA damage did not differ among sites.

    A remedial investigation/feasibility study (RI/FS) of the Calcasieu Estuary cooperative site was initiated in 1998. This site, which is located in the southwestern portion of Louisiana in the vicinity of Lake Charles, includes the portion of the estuary from the saltwater barrier on the Calcasieu River to Moss Lake. As part of the RI/FS, a baseline ecological risk assessment (BERA) was conducted to assess the risks to aquatic organisms and aquatic-dependent wildlife exposed to environmental contaminants. The purpose of the BERA was to determine if adverse effects on ecological receptors are occurring in the estuary; to evaluate the nature, severity, and areal extent of any such effects; and to identify the substances that are causing or substantially contributing to effects on ecological receptors. This article describes the environmental setting and site history, identifies the chemicals of potential concern, presents the exposure scenarios and conceptual model for the site, and summarizes the assessment and measurement endpoints that were used in the investigation. Two additional articles in this series describe the results of an evaluation of effects-based sediment-quality guidelines as well as an assessment of risks to benthic invertebrates associated with exposure to contaminated sediment.

    A coalbed methane (CBM) well in Winn Parish, Louisiana, named CZ Fee A No. 114, was drilled by Vintage Petroleum, Inc., in January 2004. The CZ Fee A No. 114 CBM well was drilled to a total depth of 3,114 ft and perforated at 2,730-2,734 ft in a Wilcox Group (Paleocene-Eocene) coal bed. Analytical data from the drilling project have been released by Vintage Petroleum, Inc., and by the current well operator, Hilcorp Energy Corporation (see Appendix) to the Louisiana Geological Survey (LGS) and the U.S. Geological Survey (USGS) for publication. General information about the CZ Fee A No. 114 CBM well is compiled in Table 1, and analytical data from the well are included in following sections. The CZ Fee A No. 114 well is located in eastern Winn Parish, approximately 30 mi east of where Wilcox Group strata crop out on the Sabine Uplift (fig. 1). In the CZ Fee A No. 114 well, lower Wilcox Paleocene coal beds targeted for CBM production occur at depths of 2,600-3,000 ft (fig. 2). Average monthly gas production for the reporting period August 1, 2004, through May 1, 2005, was 450 thousand cubic feet (Mcf) (Louisiana Department of Natural Resources, 2005).

    Three sets of effects-based sediment-quality guidelines (SQGs) were evaluated to support the selection of sediment-quality benchmarks for assessing risks to benthic invertebrates in the Calcasieu Estuary, Louisiana. These SQGs included probable effect concentrations (PECs), effects range median values (ERMs), and logistic regression model (LRMs)-based T50 values. The results of this investigation indicate that all three sets of SQGs tend to underestimate sediment toxicity in the Calcasieu Estuary (i.e., relative to the national data sets), as evaluated using the results of 10-day toxicity tests with the amphipod, Hyalella azteca, or Ampelisca abdita, and 28-day whole-sediment toxicity tests with the H. azteca. These results emphasize the importance of deriving site-specific toxicity thresholds for assessing risks to benthic invertebrates.

  1. Influences on Adaptive Planning to Reduce Flood Risks among Parishes in South Louisiana

    Directory of Open Access Journals (Sweden)

    Full Text Available Residents of south Louisiana face a range of increasing, climate-related flood exposure risks that could be reduced through local floodplain management and hazard mitigation planning. A major incentive for community planning to reduce exposure to flood risks is offered by the Community Rating System (CRS of the National Flood Insurance Program (NFIP. The NFIP encourages local collective action by offering reduced flood insurance premiums for individual policy holders of communities where suggested risk-reducing measures have been implemented. This preliminary analysis examines the extent to which parishes (counties in southern Louisiana have implemented the suggested policy actions and identifies key factors that account for variation in the implementation of the measures. More measures implemented results in higher CRS scores. Potential influences on scores include socioeconomic attributes of residents, government capacity, average elevation and past flood events. The results of multiple regression analysis indicate that higher CRS scores are associated most closely with higher median housing values. Furthermore, higher scores are found in parishes with more local municipalities that participate in the CRS program. The number of floods in the last five years and the revenue base of the parish does not appear to influence CRS scores. The results shed light on the conditions under which local adaptive planning to mitigate increasing flood risks is more likely to be implemented and offer insights for program administrators, researchers and community stakeholders.

    The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project, conducts baseline and storm-response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms (Morgan, 2009). On September 9-10, 2008, the USGS conducted an oblique aerial photographic survey from Calcasieu Lake, Louisiana, to Brownsville, Texas, aboard a Cessna C-210 (aircraft) at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect baseline data for assessing incremental changes of the beach and nearshore area, and the data can be used in the assessment of future coastal change.The photographs provided in this report are Joint Photographic Experts Group (JPEG) images. ExifTool was used to add the following to the header of each photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. The photograph locations are an estimate of the position of the aircraft at the time the photograph was taken and do not indicate the location of any feature in the images (see the Navigation Data page). These photographs document the state of the barrier islands and other coastal features at the time of the survey. Pages containing thumbnail images of the photographs, referred to as contact sheets, were created in 5-minute segments of flight time. These segments can be found on the Photos and Maps page. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet.In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail. The KML file was created using the photographic navigation files. The KML file can be found in the kml folder.

    The Strategic Petroleum Reserve (SPR) Weeks Island site is one of five underground salt dome crude oils storage facilities operated by the Department of Energy (DOE). It is located in Iberia Parish, Louisiana. The purpose of the proposed action is to decommission the Weeks Island crude oil storage after the oil inventory has been transferred to other SPR facilities. Water intrusion into the salt dome storage chambers and the development of two sinkholes located near the aboveground facilities has created uncertain geophysical conditions. This Environmental Assessment describes the proposed decommissioning operation, its alternatives, and potential environmental impacts. Based on this analyses, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) and has issued the Finding of No Significant Impact (FONSI).

    The proposed action and three alternatives, including a No Build alternative, were evaluated along the existing RWIPL alignment to accommodate the placement of the proposed RWIPL. Construction feasibility, reasonableness and potential environmental impacts were considered during the evaluation of the four actions (and action alternatives) for the proposed RWIPL activities. Reasonable actions were identified as those actions which were considered to be supported by common sense and sound technical principles. Feasible actions were those actions which were considered to be capable of being accomplished, practicable and non-excessive in terms of cost. The evaluation process considered the following design specifications, which were determined to be important to the feasibility of the overall project. The proposed RWIPL replacement project must therefore: (1) Comply with the existing design basis and criteria, (2) Maintain continuity of operation of the facility during construction, (3)Provide the required service life, (4) Be cost effective, (5)Improve the operation and maintenance of the pipeline, and (6) Maintain minimal environmental impact while meeting the performance requirements. Sizing of the pipe, piping construction materials, construction method (e.g., open-cut trench, directional drilling, etc.) and the acquisition of new Right-of-Way (ROW) were additionally evaluated in the preliminary alternative identification, selection and screening process.

    2012-12-01

    St. Bernard Parish, located in southeast Louisiana, is rapidly losing coastal forests and wetlands due to a variety of natural and anthropogenic disturbances (e.g. subsidence, saltwater intrusion, low sedimentation, nutrient deficiency, herbivory, canal dredging, levee construction, spread of invasive species, etc.). After Hurricane Katrina severely impacted the area in 2005, multiple Non-Governmental Organizations (NGOs) have focused not only on rebuilding destroyed dwellings, but on rebuilding the ecosystems that once protected the citizens of St. Bernard Parish. Volunteer groups, NGOs, and government entities often work separately and independently of each other and use different sets of information to choose the best planting sites for restoring coastal forests. Using NASA Earth Observing Systems (EOS), Natural Resource Conservation Service (NRCS) soil surveys, and ancillary road and canal data in conjunction with ground truthing, the team created maps of optimal planting sites for several species of bottomland hardwood trees to aid in unifying these organizations, who share a common goal, under one plan. The methodology for this project created a comprehensive Geographic Information System (GIS) to help identify suitable planting sites in St. Bernard Parish. This included supplementing existing elevation data using Digital Elevation Models derived from LIDAR data, and determining existing land cover in the study area from classified Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery. Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data from a single low-altitude swath was used to assess the health of vegetation over an area near the Mississippi River Gulf Outlet Canal (MRGO) and Bayou La Loutre. Historic extent of coastal forests was also mapped using aerial photos collected between 1952 and 1956. The final products demonstrated yet another application of NASA EOS in the rebuilding and monitoring of coastal ecosystems in

    The sediments in the Calcasieu Estuary are contaminated with a wide variety of chemicals of potential concern (COPCs), including heavy metals, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalates, chlorinated benzenes, and polychlorinated dibenzo-p-dioxins and dibenzofurans. The sources of these COPCs include both point and non-point source discharges. As part of a baseline ecological risk assessment, the risks to benthic invertebrates posed by exposure to sediment-associated COPCs were assessed using five lines of evidence, including whole-sediment chemistry, pore-water chemistry, whole-sediment toxicity, pore-water toxicity, and benthic invertebrate community structure. The results of this assessment indicated that exposure to whole sediments and/or pore water from the Calcasieu Estuary generally posed low risks to benthic invertebrate communities (i.e., risks were classified as low for 68% of the sampling locations investigated). However, incremental risks to benthic invertebrates (i.e., compared with those associated with exposure to conditions in reference areas) were indicated for 32% of the sampling locations within the estuary. Of the three areas of concern (AOCs) investigated, the risks to benthic invertebrates were highest in the Bayou d'Inde AOC; risks were generally lower in the Upper Calcasieu River AOC and Middle Calcasieu River AOC. The areas showing the highest risks to sediment-dwelling organisms were generally located in the vicinity of point source discharges of COPCs. These results provided risk managers with the information required to make decisions regarding the need for remedial actions at the site.

    The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), is an invasive pest of sugarcane, Saccharum spp., rice, Oryza sativa L., and other graminaceous crops in the Gulf Coast region of the United States. Traps baited with E. loftini female sex pheromones were used to document establishment and distribution of E. loftini near sugarcane, rice, and noncrop hosts in seven southwest Louisiana parishes from 2009 to 2013. Additional field surveys documented larval infestations in commercial sugarcane and rice. After its initial detection in 2008, no E. loftini were detected in Louisiana in 2009 and only two adults were captured in 2010. Trapping documented range expansion into Cameron, Beauregard, and Jefferson Davis parishes in 2011 and Allen, Acadia, and Vermilion parishes in 2013. During the course of this study, E. loftini expanded its range eastward into Louisiana 120 km from the Texas border (≈22 km/yr). Surveys of larval infestations provided the first record of E. loftini attacking rice and sugarcane in Louisiana. Infestations of E. loftini in rice planted without insecticidal seed treatments in Calcasieu Parish reached damaging levels. PMID:26313982

    The Crown Zellerbach Well No. 2, approximately 23 miles east of Baton Rouge, Louisiana, is the eighth successful test of a geopressured-geothermal aquifer under the DOE Wells of Opportunity program. The well was tested through the annulus between 7-inch casing and 2-3/8 inch tubing. Two flow tests and one reservoir pressure buildup test were conducted on the lower zone during a 13-day period. A total of 12,489 barrels of water was produced. The highest flow rate achieved was about 3887 BWPD. One flow test followed by a buildup period was conducted on the combined upper and lower zones during a 3-day period. A total of 4739 barrels of water was produced. The highest flow rate achieved was about 3000 BWPD. The gas/water ratio measured during testing was about 32.0 SCF/BBL for the lower zone. The extrapolated latoratory data indicates that the solubility of the gas is 55.7 SCF/BBL. It appears that the reservoir brine is considerably undersaturated. The methane content of the flare line gas averaged 71.0 mole percent. Crown Zellerbach Company carefully studied the commercial feasibility of using the well to produce energy for a wood-drying facility and decided against the project.

    1978-12-01

    Gruy Federal, Inc. (Gruy) operates under Contract No. EG-77-C-08-1528 to the Department of Energy, Division of Geothermal Energy, to evaluate potential alternate energy sources occurring within geopressured-geothermal (Geo) aquifers in Miocene, Oligocene, Tuscaloosa, Wilcox, and Frio formations along the Texas and Louisiana Gulf Coast. The project is entitled ''Investigation and Evaluation of Geopressured-Geothermal Wells''. The original period of performance was from September 26, 1977, through September 30, 1978; the contract was later extended through September 30, 1979. The first well on which testing was attempted under this contract was the Alice C. Plantation No. 2 Well, located in St. Mary Parish, Louisiana. Originally drilled by the Sun Oil Company to a total depth of 19,000 feet, this well was abandoned as a dry hole in January 1964. Gruy's reentry attempt ended with plugging and abandonment after a saltwater flow on September 17, 1978. This report is a comprehensive document detailing all events and costs relating to the Alice C. plantation well, from its initial selection as a reentry well through the plugging and abandonment operations.

    Willits, M.H.; McCoy, R.L.; Dobson, R.J.; Hartsock, J.H.

    1979-12-01

    The Fairfax Foster Sutter No. 2 well, located in the East Franklin area of St. Mary Parish, Louisiana, is the first successful test of a geopressured-geothermal aquifer under the Well-of-Opportunity program. The section tested was the MA-6 sand of lower Miocene age which has produced large quantities of gas from the adjacent but structurally separated Garden City field. In the subject well the observed temperature was 270{sup 0}F (132{sup 0}C) and the measured gradient was 0.77 psi/ft. The gross sand thickness was 270 feet, the net sand thickness 190 feet, and the tested interval 58 net feet. The temperatures and pressures encountered approached the limits of the surface-recording bottomhole pressure gauge and particularly the single-conductor cables on which the gauges were run. The objectives of the tests were all accomplished, and data were obtained which will contribute to the overall assessment of the geopressured-geothermal resource of the Upper Gulf of Mexico basin. In general, the gas solubility (22.8 scf/bbl) was as expected for the temperature, pressure, and salinity of the brine. The produced water was more saline than expected (160,000 mg/l). The high concentrations of dissolved solids, coupled with the evolution of CO{sub 2} from these waters during production, created a scaling problem in the tubular goods and surface equipment that will have to be addressed in future tests.

  20. Depositional Model for the Middle Eocene Oberlin Sand in Northwest Oberlin Field and Adjacent Areas, Allen Parish, Louisiana: A Well-log and Seismic Analysis

    Science.gov (United States)

    McVey, Timothy Keith

    The depositional environment of the middle to late Eocene Oberlin sand of Northwest Oberlin Field and Pilgrim Church Field in central Allen Parish, Louisiana, was investigated. The depositional environment of the Oberlin sand has been interpreted from observations of spontaneous potential log signatures, conventional core reports, paleontological reports, shape of isochore maps, coherency extraction attribute, amplitude extraction attribute, and multiple seismic and subsurface cross sections. Focus is centered on the juxtaposition of component sand bodies and their proximity to the interdistributary and prodelta environments. Sand bodies include distributary channels, distributary mouth bars, crevasse subdeltas and shelfal bars and are interpreted to be the products of lower deltaic and shelf processes. The results of this study are based on seismic analysis, display techniques and subsurface maps calibrated to well logs, models, and recognition criteria of modern and ancient depositional environments previously described in the regional literature. The integration of all available data provides an objective and systematic approach detailing the origin, lateral extent, geometry and architecture of the Oberlin sand in the lower deltaic plain and shelf environments. The results of this study may be applicable to similar age sands on trend with the study area. Understanding of sand component types of the lower deltaic and shelf environments is vital to exploration success and development optimization of hydrocarbon bearing reservoirs.

    1994-12-01

    The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipeline on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and night of-way (ROW) management practices. This report presents the results of a survey conducted over the period of August 12-13, 1991, at the Bayou Grand Cane crossing in De Soto Parish, Louisiana, where a pipeline constructed three years prior to the survey crosses the bayou through mature bottomland hardwoods. The sit was not seeded or fertilized after construction activities. At the time of sampling, a dense herb stratum (composed of mostly native species) covered the 20-m-wide ROW, except within drainage channels. As a result of the creation of the ROW, new habitat was created, plant diversity increased, and forest habitat became fragmented. The ROW must be maintained at an early stage of succession to allow access to the pipeline however, impacts to the wetland were minimized by decreasing the width of the ROW to 20 m and recreating the drainage channels across the ROW. The canopy trees on the ROW`s edge shaded part of the ROW, which helped to minimize the effects of the ROW.

    The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and night- of-way management practices. This report presents the results of a survey conducted on August 22, 1991, in an emergent intertidal estuarine wetland in Terrebonne Parish, Louisiana. The site includes three pipelines installed between 1958 and 1969. Vegetation within the site comprises three native tidal marsh grasses: Spartina alterniflora, Spartina patens, and Distichlis spicata. All three species occurred over the pipelines, within the right-of-way and in both natural areas. Vegetative differences attributable to the installation or presence of the pipelines were not obvious over the pipelines or in the habitat east of the pipelines. However, because of the presence of a canal west of the 1969 pipeline, vegetation was less abundant in that area, and D. spicata was absent from all but the most distant plots of the transacts. Data obtained in the study indicate that when rights-of-way through brackish marsh are restored to their original elevations, they are revegetated with native vegetation similar to that in surrounding areas.

  3. An Environmental Assessment of Proposed Geothermal Well Testing in the Tigre Lagoon Oil Field, Vermilion Parish, Louisiana

    1976-03-01

    This report is an environmental assessment of the proposed testing of two geopressured, geothermal aquifers in central coastal Louisiana. On the basis of an analysis of the environmental setting, subsurface characteristics, and the proposed action, potential environmental impacts are determined and evaluated together with potential conflicts with federal, state, and local programs. Oil and gas wells in coastal Louisiana have penetrated a potentially productive geothermal zone of abnormally high-pressured aquifers that also yield large volumes of natural gas. To evaluate the extent to which the geothermal-geopressured water can be used as an alternative energy source and to what extent withdrawal of geopressured water can enhance gas production, it is necessary that flow rates, composition and temperature of fluids and gases, recharge characteristics, pressures, compressibilities, and other hydrodynamic and boundary conditions of the reservoir be determined by means of production tests. Tests are further necessary to evaluate and seek solutions to technological problems.

  4. Water-quality and bottom-material characteristics of Cross Lake, Caddo Parish, Louisiana, 1997-99

    McGee, Benton D.

    2004-01-01

    Cross Lake is a shallow, monomictic lake that was formed in 1926 by the impoundment of Cross Bayou. The lake is the primary drinking-water supply for the City of Shreveport, Louisiana. In recent years, the lakeshore has become increasinginly urbanized. In addition, the land use of the watershed contributing runoff to Cross Lake has changed. Changes in land use and urbanization could affect the water chemistry and biology of the Lake. Water-quality data were collected at 10 sites on Cross Lake from February 1997 to February 1999. Water-column and bottom-material samples were collected. The water-column samples were collected at least four times per year. These samples included physical and chemical-related properties such as water temperature, dissolved oxygen, pH, and specific conductance; selected major inorganic ions; nutrients; minor elements; organic chemical constituents; and bacteria. Suspended-sediment samples were collected seven times during the sampling period. The bottom-material samples, which were collected once during the sampling period, were analyzed for selected minor elements and inorganic carbon. Aside from the nutrient-enriched condition of Cross Lake, the overall water-quality of Cross Lake is good. No primary Federal or State water-quality criteria were exceeded by any of the water-quality constituents analyzed for this report. Concentrations of major inorganic constituents, except iron and manganese, were low. Water from the lake is a sodium-bicarbonate type and is soft. Minor elements and organic compounds were present in low concentrations, many below detection limits. Nitrogen and phosphorus were the nutrients occurring in the highest concentrations. Nutrients were evenly distributed across the lake with no particular water-quality site indicating consistently higher or lower nutrient concentrations. No water samples analyzed for nitrate exceeded the U.S. Environmental Protection Agency's Maximum Contaminant Level of 10 milligrams per

  9. Magnetic susceptibility mapping of fly ash in soil samples near a coal-burning power plant in Pointe Coupee Parish, Louisiana.

    Science.gov (United States)

    Elhelou, O.; Richter, C.

    2015-12-01

    Atmospheric deposition of pollutants is a major health and environmental concern. In a 2010 study, the CATF attributed over 13,000 deaths each year to fly ash and other fine particles emitted by U.S. coal-burning power plants. The magnetic properties of fly ash allows for mapping an area suspect of PM pollution faster and more efficiently than by conducting chemical analysis as the former alternative. The objective of this study is to detect the presence of magnetic particles related to the migration of fly ash from a nearby coal power plant over parts of Pointe Coupee Parish, LA. This is based on the idea that the fly ash that is released into the atmosphere during the coal burning process contains heavy metals and magnetic particles in the form of ferrospheres, which can be used to trace back to the source. Maps of the top and sub soil were generated to differentiate the magnetic susceptibility values of the heavy metals potentially attributed to the migration and settling of fly ash onto the surface from any pre-existing or naturally occurring heavy metals in the sub soil. A 60 km2 area in Pointe Coupee Parish was investigated in approximately 0.5 km2 subsets. The area in Pointe Coupee Parish, LA was selected because land use is predominantly rural with the Big Cajun II power plant as the main contributor for air borne contaminants. Samples of fly ash obtained directly from the source below one of the power plant's precipitators were also analyzed to verify the field and laboratory analysis. Contour maps representing the spatial distribution of fly ash over Pointe Coupee, LA, along with histograms of magnetic susceptibility values, and chemical analysis all indicate a correlation between the proximity to the power plant and the predominant wind direction. Acquisition curves of the isothermal remnant magnetization demonstrate the presence of predominantly low coercivity minerals (magnetite) with a small amount of a high-coercivity phase. The microstructure of the

    Prakken, Lawrence B.; Griffith, Jason M.; Fendick, Robert B.

    2012-01-01

    In 2005, about 30.6 million gallons per day (Mgal/d) of water was withdrawn in Beauregard Parish, Louisiana, including about 30.4 Mgal/d from groundwater sources and 0.1 Mgal/d from surface water sources. Industrial use, primarily for wood products, accounted for about 72 percent (22.0 Mgal/d) of the total water withdrawn. Other categories of use included public supply, rural domestic, livestock, rice irrigation, general irrigation, and aquaculture. Water-use data collected at 5-year intervals from 1960 to 2005 indicate water withdrawals in the parish peaked at about 43.5 Mgal/d in 1985. The large increase in groundwater usage from 1970 to 1975 was primarily due to industrial withdrawals, which increased from 3.64 Mgl/d in 1970 to 29.0 Mgal/d in 1975. This fact sheet summarizes information on the water resources of Beauregard Parish, La. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports listed in the Selected References section.

  13. Testing geopressured geothermal reservoirs in existing wells. Final report P. R. Girouard Well No. 1, Lafayette Parish, Louisiana. Volume I. Completion and testing

    1981-01-01

    The P.R. Girouard No. 1 Well, located approximately 10 miles southeast of Lafayette, Louisiana, was the fourth successful test of a geopressured-geothermal aquifer under the Wells of Opportunity program. The well was tested through 3-1/2 inch tubing set on a packer at 14,570 feet without major problems. The geological section tested was the Oligocene Marginulina Texana No. 1 sand of upper Frio age. The interval tested was from 14,744 to 14,819 feet. Produced water was piped down a disposal well perforated from 2870 to 3000 feet in a Miocene saltwater sand. Four flow tests were conducted for sustained production rates of approximately 4000 BWPD to approximately 15,000 BWPD. The highest achieved, during a fifth short test, was 18,460 BWPD. The test equipment was capable of handling higher rates. The gas-to-water ratio was relatively uniform at approximately 40 SCF/bbl. The heating value of the gas is 970 Btu/SCF. The reservoir tests show that is is doubtful that this well would sustain production rates over 10,000 BWPD for any lengthy period from the sand zone in which it was completed. This limited flow capacity is due to the well's poor location in the reservoir and is not a result of any production deficiencies of the Marginulina Texana sand.

  18. Hydrologic modeling as a tool for land management and contingency planning in the Calcasieu Sabine Basin. Volume 1

    International Nuclear Information System (INIS)

    The Calcasieu-Sabine Basin in southwest Louisiana contains approximately 126,518 hectares of wetlands, consisting of fresh marsh, intermediate marsh, brackish marsh and saline marsh. The hydrodynamics of the basin involves a combination of estuarine processes such as saltwater intrusion, response to water level fluctuations at an open boundary and lake dynamics. The basin is also affected by deep ship channels. As such, a robust, flexible and efficient numerical model is needed to incorporate all of these processes in an operational program. This study developed a hydrodynamic and salinity model for a portion of the basin that includes the lakes and marshes for the purpose of land management and contingency planning. The newly developed finite-difference hydrodynamic and salinity model is a combination of 1 and 2 dimensional computations and is intended for land, wildlife and habitat management. It can be used as a coastal restoration tool to evaluate the effectiveness of future and ongoing coastal restoration projects. The model was calibrated and validated against field measurements. It was shown to produce accurate simulations of the complex flow patterns of the Calcasieu-Sabine Basin along with information on salinity, water level fluctuations, velocities and discharges throughout the main channels and open water bodies within the area. It was concluded that the model provides a very useful planning and adaptive management tool to improve the understanding of the complex hydrology and salinity circulation pattern within the system. 5 refs., 4 tabs., 9 figs

  14. Livingston Parish Landfill Methane Recovery Project (Feasibility Study)

    Energy Technology Data Exchange (ETDEWEB)

    White, Steven

    2012-11-15

    The Woodside Landfill is owned by Livingston Parish, Louisiana and is operated under contract by Waste Management of Louisiana LLC. This public owner/private operator partnership is commonplace in the solid waste industry today. The landfill has been in operation since approximately 1988 and has a permitted capacity of approximately 41 million cubic yards. Based on an assumed in-place waste density of 0.94 ton per cubic yard, the landfill could have an expected design capacity of 39.3 million tons. The landfill does have an active landfill gas collection and control system (LFGCCS) in place because it meets the minimum thresholds for the New Source Performance Standards (NSPS). The initial LFGCS was installed prior to 2006 and subsequent phases were installed in 2007 and 2010. The Parish received a grant from the United States Department of Energy in 2009 to evaluate the potential for landfill gas recovery and utilization at the Woodside Landfill. This includes a technical and economic feasibility study of a project to install a landfill gas to energy (LFGTE) plant and to compare alternative technologies. The LFGTE plant can take the form of on-site electrical generation, a direct use/medium Btu option, or a high-Btu upgrade technology. The technical evaluation in Section 2 of this report concludes that landfill gas from the Woodside landfill is suitable for recovery and utilization. The financial evaluations in sections 3, 4, and 5 of this report provide financial estimates of the returns for various utilization technologies. The report concludes that the most economically viable project is the Electricity Generation option, subject to the Parish’s ability and willingness to allocate adequate cash for initial capital and/or to obtain debt financing. However, even this option does not present a solid return: by our estimates, there is a 19 year simple payback on the electricity generation option. All of the energy recovery options discussed in this report

  15. Geothermal Energy Geopressure Subprogram: DOE Lafourche Crossing No. 1, Terrebonne Parish and Lafourche Parish, Louisiana: Environmental assessment

    Energy Technology Data Exchange (ETDEWEB)

    1978-10-01

    The proposed action will consist of drilling one geothermal fluid well for intermittent production testing of 284 days over a three year period. Two disposal wells will initially be drilled to provide disposal of lower volume fluids produced during initial testing. Two additional disposal wells will be drilled, logged, completed, tested, and operated prior to commencement of high volume fluid production. Construction of the proposed action will change the land-use of 2 ha (5 ac) for the test well and each of the injection wells from agriculture or wetlands to resource exploration. Lands will be cleared and erosion and runoff will result. During operation of the well test, the only expected impacts are from venting of gases or flaring of gases and noise. After the tests are completed, the area will be restored as much as possible to its natural condition by revegetation programs using nature species. All sources of pollutants will be collected and disposed in environmentally acceptable ways. Accidents may result from this proposed action.

  18. THE PARISH AS AN OPEN SOCIETY

    Directory of Open Access Journals (Sweden)

    Constantin NECULA

    2015-04-01

    Full Text Available In all the thrill of the modern definitions of the social function of everyday life, we often forget about the basic human organizations that created the social cohesion which survived over the history during difficult times. A sort of memory aneurysm prevents us from rediscovering those communicational structures that created the real human community, which generated it free of any ideologies and fanaticisms, which raised it in the modern social network. The parish, humble social community based on the confession of the same faith and the stretching of a given geography, was mocked, eluded and informally deformed. It remains, though, one of the greatest miracles of the sociology of social organization, one of the communicational categories preserved, it seems, despite the evolution of virtual communication. It is enough to cross, for instance, the great highways of modern Europe, as well as the British area to see that the names of cities, thousands of them, are related to the Christian culture of the place. A certain saint or boards which attest the Christian past of the place, marking points of the spiritual amperage of the area, are lumps in an informal network that proves that the parish remains one of the sociological categories of communication that remains deeply implemented in the mentality of the modern man. Even if it lacks the same spiritual or cultural connotation, it remains the model of the open society, placed in the interval of the new models, destructured from the very moment of their hermeneutical assertion.

    This study examines the maternal mortality rate in six early modern rural parishes of East Anglia where a midwife was known to be practicing. Register entries from the six parishes are translated and transcribed and maternal outcomes established and discussed. Midwives and their families are researched to establish marital status, parity and social standing. Maternal mortality is calculated and differing rates for women experiencing multiple births, stillbirths and base births examined.

  1. Potentiometric surface, 2012, and water-level differences, 2005-12, of the Sparta Aquifer in north-central Louisiana

    Science.gov (United States)

    McGee, Benton D.; Brantly, Jeffrey A.

    2015-01-01

    The Sparta aquifer is used in 15 parishes in north-central Louisiana, primarily for public supply and industrial purposes. Of those parishes, eight (Bienville, Claiborne, Jackson, Lincoln, Ouachita, Union, Webster, and Winn) rely on the Sparta aquifer as their principal source of groundwater. In 2010, withdrawals from the Sparta aquifer in Louisiana totaled 63.11 million gallons per day (Mgal/d), a reduction of more than 11 percent from 1995, when the highest rate of withdrawals (71.32 Mgal/d) from the Sparta aquifer were documented. The Sparta aquifer provides water for a variety of purposes which include public supply (34.61 Mgal/d), industrial (25.60 Mgal/d), rural domestic (1.50 Mgal/d), and various agricultural (1.40 Mgal/d). Of the 13 major aquifers or aquifer systems in Louisiana, the Sparta aquifer is currently (2012) the sixth most heavily pumped. The Sparta aquifer is the second most heavily pumped aquifer in Arkansas, which borders Louisiana to the north. In 2005, 170 Mgal/d were withdrawn from the Sparta aquifer in eastern and southern Arkansas; of that total, about 15.55 Mgal/d were withdrawn from the aquifer in Union County, which borders Claiborne and Union Parishes to the north. By 1997, a large cone of depression (a cone-shaped depression in the potentiometric surface caused by and centered on a pumping well or wells) in the Sparta aquifer centered over Union County had merged with the cone of depression at West Monroe. In 2004, the rate of withdrawal from the Sparta aquifer in Union County began to decline and water levels in the aquifer began to rise in nearby areas of Arkansas and Louisiana.

  2. Channel Utilization in South Louisiana Using AIS Data, 2011-2012

    Directory of Open Access Journals (Sweden)

    M.J. Kaiser

    2014-12-01

    Full Text Available South Louisiana is undergoing rapid land loss and the construction and utilization of navigation channels by the offshore oil and gas industry, the commercial fishing industry, the oil refining industry, and freight shippers is one cause. A network of natural and man-made navigation channels support commerce and industry throughout the region, but no quantitative information is available on the users of the channels and their contribution to land loss. The purpose of this note is to characterize utilization across eight channels in South Louisiana using data from the Automatic Identification System. Approximately 125,000 vessels used the channels over a two year period between 2011-2012. The Mississippi River was the most heavily utilized channel with an average of 345 vessels per week across the report zone, followed by Bayou Lafourche and Sabine Pass with about 195 vessels per week. The oil refining industry was the primary user of the Calcasieu and Sabine Pass channels while the freight industry was the primary user of the Mississippi River. The offshore oil and gas industry were the primary users of Bayou Lafourche, the Houma Navigation Canal, the Atchafalaya River and Freshwater Bayou.

  10. Godchaux Well No. 1, Vermilion Parish, Louisiana: completion and testing. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1981-01-01

    The Godchaux Well No. 1 was originally drilled too a total depth of 16,000 feet in January, 1981 by C and K Petroleum, Inc. and was temporarily abandoned. The well was re-entered by Eaton on 6 August 1981 in an effort to clean out the original open hole below the 7-5/8 inch liner and test a section of the Planulina sand at a depth ranging from 15,584 to 15,692 feet. The reservoir pressure was estimated to be 14,480 psi, and the temperature of the formation water was expected to be 298/sup 0/F. The water salinity was predicted to be 70,000 ppM. The well was expected to produce up to 20,000 BWPD, was a gas content of 44 SCF per barrel. An optional test of a zone from 14,905 to 15,006 feet was also proposed in the detailed completion prognosis, which preceded the attempted test. In the process of drilling the cement plug set by the original operators, the drill string became side-tracked from the original hole. While drilling at 14,510 feet a severe loss of circulation of drilling fluid occurred through a hole in the intermediate casing. The reduction in hydrostatic head resulting from lost circulation caused the open hole to close around and stick the drill string. Efforts to repair the intermediate casing and return to normal operations were estimated to be prohibitively expensive in view of the expected poor probability of success; accordingly, the decision to plug and abandon was carried out on September 12, 1981.

    Brugia lepori sp. n., a filarial nematode from the abdominal lymphatics and subcutaneous tissues of rabbits (Sylvilagus aquaticus, S. floridanus), from St. Tammany Parish, Louisiana, is described. Brugia lepori is of moderate size (males 12 to 19 mm, females 39 to 45 mm) and within the genus most closely resembles Brugia beaveri of the raccoon, from which it can be distinguished by its larger size, smaller spicules, and smaller microfilaria which has a shorter cephalic space. Brugia lepori is only the second species of Brugia described from North America and the third species reported from the Western Hemisphere. PMID:6502360

  14. Modern-day tectonic subsidence in coastal Louisiana

    Science.gov (United States)

    Dokka, Roy K.

    2006-04-01

    Subsidence is leading to the slow inundation of communities and wetlands of Louisiana, Mississippi, Texas, and Alabama (United States) by the Gulf of Mexico. The prevailing paradigm considers subsidence to be the result of young sediment compaction and/or consolidation and human activities. This paper describes the results of a test of this theory based on an examination of historic motions of benchmark in the Michoud area of Orleans Parish, Louisiana. This methodology allowed for an assessment of vertical change at different levels over time relative to a precise vertical datum (North American Vertical Datum of 1988, NAVD88). Data do not support the current theory on the origins of subsidence; they demonstrate that tectonic causes dominate in the study area. During 1969 1971 and 1971 1977, tectonism was responsible for -16.9 mm/yr and -7.1 mm/yr of subsidence, respectively. These contributions account for 73% and 50% of the total subsidence during these intervals. The change in deep subsidence is attributed to renewed motion along a large normal fault (Michoud fault). Over the same time intervals, intermediate depth subsidence due to compaction of Pleistocene to middle Miocene strata was constant (-4.6 mm/yr). Similarly, subsidence due to shallow processes, i.e., sediment compaction and groundwater offtake, was -1.5 mm/yr and -2.5 mm/yr. Subsidence associated with petroleum extraction was not a factor due to the lack of local production.

  15. Possible linkages between lignite aquifers, pathogenic microbes, and renal pelvic cancer in northwestern Louisiana, USA

    2006-12-15

    In May and September, 2002, 14 private residential drinking water wells, one dewatering well at a lignite mine, eight surface water sites, and lignite from an active coal mine were sampled in five Parishes of northwestern Louisiana, USA. Using a geographic information system (GIS), wells were selected that were likely to draw water that had been in contact with lignite; control wells were located in areas devoid of lignite deposits. Well water samples were analyzed for pH, conductivity, organic compounds, and nutrient and anion concentrations. All samples were further tested for presence of fungi (cultures maintained for up to 28 days and colonies counted and identified microscopically) and for metal and trace element concentration by inductively-coupled plasma mass spectrometry and atomic emission spectrometry. Surface water samples were tested for dissolved oxygen and presence of pathogenic leptospiral bacteria. The Spearman correlation method was used to assess the association between the endpoints for these field/laboratory analyses and incidence of cancer of the renal pelvis (RPC) based on data obtained from the Louisiana Tumor Registry for the five Parishes included in the study. Significant associations were revealed between the cancer rate and the presence in drinking water of organic compounds, the fungi Zygomycetes, the nutrients PO{sub 4} and NH{sub 3}, and 13 chemical elements. Presence of human pathogenic leptospires was detected in four out of eight (50%) of the surface water sites sampled.

  17. Louisiana's statewide beach cleanup

    Science.gov (United States)

    Lindstedt, Dianne M.; Holmes, Joseph C.

    1989-01-01

    Litter along Lousiana's beaches has become a well-recognized problem. In September 1987, Louisiana's first statewide beach cleanup attracted about 3300 volunteers who filled 16,000 bags with trash collected along 15 beaches. An estimated 800,173 items were gathered. Forty percent of the items were made of plastic and 11% were of polystyrene. Of all the litter collected, 37% was beverage-related. Litter from the oil and gas, commercial fishing, and maritime shipping industries was found, as well as that left by recreational users. Although beach cleanups temporarily rid Louisiana beaches of litter, the real value of the effort is in public participation and education. Civic groups, school children, and individuals have benefited by increasing their awareness of the problems of trash disposal.

  19. Some factors affecting marital isonymy in three Outer Hebridean parishes.

    Science.gov (United States)

    Clegg, F J

    2001-01-01

    Log linear analysis was used to investigate the relationships between spouse isonymy and parental isonymy, time, endogamy/exogamy and groom's occupation in a total of 6266 first marriages of parish-born spouses in the civil parishes of Harris, Barra and Stornoway, between 1855 and 1990. Stornoway was divided into rural and urban (Burgh) components. Spouse isonymy comprised between 6% and 12% of all marriages, parental isonymy was generally slightly more frequent, due probably to the occurrence of occasional families in which both sets of parents were isonymous. Between 38% and 51% of marriages were endogamous. In the multi-way contingency tables, good fits between observed and expected cell numbers were obtained by a simple model, comprising the main effect of spouse isonymy and the first-order interactions between spouse isonymy and the independent variables. Inspection of the coefficients showed that in all four populations spouse isonymy was positively related to parental isonymy (doubtfully so in the case of Barra). The other independent variables showed less clear-cut relationships--endogamy/exogamy in Barra, and groom's occupation in Stornoway Rural; time period showed no significant relationships. It is concluded that the occurrence of this 'two-generational marital isonymy' might have an effect on the breeding structure of the population. PMID:11459243

  20. Status of Water Levels and Selected Water-Quality Conditions in the Sparta-Memphis Aquifer in Arkansas and the Status of Water Levels in the Sparta Aquifer in Louisiana, Spring 2005

    2007-01-01

    The U.S. Geological Survey in cooperation with the Arkansas Natural Resources Commission, the Arkansas Geological Commission, and the Louisiana Department of Transportation and Development has monitored water levels in the Sparta Sand of Claiborne Group and Memphis Sand of Claiborne Group since the 1920's. Ground-water withdrawals have increased while water levels have declined since monitoring was initiated. This report has been produced to describe ground-water levels in the aquifers in the Sparta Sand and Memphis Sand and provide information for the management of this valuable resource. The 2005 potentiometric-surface map of the aquifers in the Sparta Sand and Memphis Sand was constructed using water-level data collected in 333 wells in Arkansas and 120 wells in Louisiana during the spring of 2005. The highest water-level altitude measured in Arkansas was 327 feet above National Geodetic Vertical Datum of 1929 located in Grant County in the outcrop at the western boundary of the study area; the lowest water-level altitude was 189 feet below National Geodetic Vertical Datum of 1929 in Union County. The highest water-level altitude measured in Louisiana was 246 feet above National Geodetic Vertical Datum of 1929 located in Bossier Parish in the outcrop area near the western boundary of the study area; the lowest water-level altitude was 226 feet below National Geodetic Vertical Datum of 1929 in central Ouachita Parish. Three large depressions centered in Columbia, Jefferson, and Union Counties in Arkansas are the result of large withdrawals for industrial and public supplies. In Louisiana, three major pumping centers are in Ouachita, Jackson, and Lincoln Parishes. Water withdrawals from these major pumping centers primarily is used for industrial and public-supply purposes. Withdrawals from Ouachita and Lincoln Parishes and Union County, Arkansas, primarily for industrial purposes, have caused the resulting cones of depression to coalesce so that the -40 foot

    Schweitzer, Roberta; Norberg, Marie; Larson, Linda

    2002-09-01

    Parish nursing has emerged as a specialized professional nursing practice in the past 10 years. Nursing literature addressing the functions of the parish nurse role in a faith community or congregation has become more prevalent in recent years. However, there is very little literature that examines the role of the parish nurse (PN) in a program leadership position. The purpose of this qualitative descriptive study is to describe the role and functions of the parish nurse coordinator (PNC) charged with leadership of a group of PNs networked together as a P N program. Specifically, this article highlights the demographics of PNCs across the United States, what they value most about being a PNC, and the challenges they experience in this leadership role. Findings are examined in light of their potential for contributing to the growth and development of nursing leadership that incorporates the spiritual dimension.

  12. Simulation of groundwater flow and chloride transport in the “1,200-foot” sand with scenarios to mitigate saltwater migration in the “2,000-foot” sand in the Baton Rouge area, Louisiana

    Science.gov (United States)

    Heywood, Charles E.; Lovelace, John K.; Griffith, Jason M.

    2015-07-16

    Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. The 10 aquifers beneath the Baton Rouge area, which includes East and West Baton Rouge Parishes, Pointe Coupee Parish, and East and West Feliciana Parishes, provided about 184.3 million gallons per day (Mgal/d) for public supply and industrial use in 2012. Groundwater withdrawals from the “1,200-foot” sand in East Baton Rouge Parish have caused water-level drawdown as large as 177 feet (ft) north of the Baton Rouge Fault and limited saltwater encroachment from south of the fault. The recently developed groundwater model for simulating transport in the “2,000-foot” sand was rediscretized to also enable transport simulation within the “1,200-foot” sand and was updated with groundwater withdrawal data through 2012. The model was recalibrated to water-level observation data through 2012 with the parameter-estimation code PEST and calibrated to observed chloride concentrations at observation wells within the “1,200-foot” sand and “2,000-foot” sand. The model is designed to evaluate strategies to control saltwater migration, including changes in the distribution of groundwater withdrawals and installation of scavenger wells to intercept saltwater before it reaches existing production wells.

  13. Environmental Assessment on the leasing of the Strategic Petroleum Reserve, St. James Terminal, St. James Parish, Louisiana

    International Nuclear Information System (INIS)

    The US Department of Energy (DOE) proposes to lease the Strategic Petroleum Reserve's (SPR) St. James Terminal to private industry. The St. James Terminal consists of six storage tanks, a pumping station, two maine docks and ancillary facilities. DOE believes that the St. James Terminal presents an opportunity to establish a government- industry arrangement that could more effectively use this asset to serve the nations's oil distribution needs, reduce the operational cost of the SPR, and provide a source of revenue for the Government. DOE solicited interest in leasing its distribution facilities in a notice published March 16, 1994. In response, industry has expressed interest in leasing the St. James Terminal, as well as several DOE pipelines, to enhance the operation of its own facilities or to avoid having to construct new ones. Under such a lease, industry use would be subordinate to DOE use in the event of a national energy emergency. This Environmental Assessment describes the proposed leasing operation, its alternatives, and potential environmental impacts. Based on this analyses, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) OF 1969 and has issued the Finding of No Significant Impact (FONSI)

    Using 28 topographic profiles, air-photo interpretation, and historical shoreline-change data, coastal processes were evaluated along the Chenier Plain to explain the occurrence, distribution, and geomorphic hierarchy of primary landforms, and existing hypotheses regarding Chenier-Plain evolution were reconsidered. The Chenier Plain of SW Louisiana, classified as a low-profile, microtidal, storm-dominated coast, is located west and downdrift of the Mississippi River deltaic plain. This Late-Holocene, marginal-deltaic environment is 200 km long and up to 30 km wide, and is composed primarily of mud deposits capped by marsh interspersed with thin sand- and shell-rich ridges ("cheniers") that have elevations of up to 4 m. In this study, the term "ridge" is used as a morphologic term for a narrow, linear or curvilinear topographic high that consists of sand and shelly material accumulated by waves and other physical coastal processes. Thus, most ridges in the Chenier Plain represent relict open-Gulf shorelines. On the basis of past movement trends of individual shorelines, ridges may be further classified as transgressive, regressive, or laterally accreted. Geomorphic zones that contain two or more regressive, transgressive, or laterally accreted ridges are termed complexes. Consequently, we further refine the Chenier-Plain definition by Otvos and Price [Otvos, E.G. and Price, W.A., 1979. Problems of chenier genesis and terminology—an overview. Marine Geology, 31: 251-263] and define Chenier Plain as containing at least two or more chenier complexes. Based on these definitions, a geomorphic hierarchy of landforms was refined relative to dominant process for the Louisiana Chenier Plain. The Chenier Plain is defined as a first-order feature (5000 km 2) composed of three second-order features (30 to 300 km 2): chenier complex, beach-ridge complex, and spit complex. Individual ridges of each complex type were further separated into third-order features: chenier, beach

    1994-08-01

    This two-volume Final Environmental Impact Statement (FEIS) was prepared by the Nuclear Regulatory Commission (NRC) in accordance with regulation 10 CFR Part 51, which implements the National Environmental Policy Act (NEPA). Volume 1 contains the assessment of the potential environmental impacts for licensing the construction and operation of a proposed gaseous centrifuge enrichment facility to be built in Claiborne Parish, Louisiana, by Louisiana Energy Services, LP. (LES). The proposed facility would have a production capacity of about 866 metric tons annually of up to 5 weight percent enriched UF{sub 6}, using a proven centrifuge technology. Included in the assessment are construction, both normal operations and potential accidents (internal and external events), and the eventual decontamination and decommissioning (D&D)- of the site. Issues addressed include the purpose and need for the facility, the alternatives to the proposed action, potential disposition of the tails, the site selection process, and environmental justice. The NRC staff concludes that the facility can be constructed and operated with small and acceptable impacts on the public and the environment. The FEIS supports issuance of a license to the applicant, Louisiana Energy Services, to authorize construction and operation of the proposed facility.

  5. Paleochannels and Sediment Characteristics of the Chenier Plain Inner Shelf, Louisiana

    Garcia-Garcia, A.; Fagherazzi, S.; Orange, D.

    2011-12-01

    In the last 3000 yrs, sediments from the Mississippi Delta have been transported to the western part of the Louisiana shelf, triggering beach progradation through a series of shell and sandy ridges (cheniers) separated by muddy hollows. Distinct events of chenier plain development have been explained as being the result of delta lobe switching in the Mississippi delta combined to local processes responsible for formation of beach ridges, recurved spits, eolian deposits, storm berms, and natural levees. In the present work we investigate the recent infill of the inner shelf off the Chenier Plain coast, just west of the recent deltaic deposits of the Mississippi River. We use shallow seismic analysis and the identification of paleochannels to understand their relationship with current rivers off the present coastline. We have been able to identify four seismic units U1 to U4 and their associated surfaces and discontinuities. A tentative reconstruction for the last 20 ky sedimentary infill is provided, correlating well with the datations available for the area. The identification and tracking of several buried channels across the shelf in units U1 and U3 let us track the position of the Mermentau-Calcasieu hydrological system in previous lowstands. It is interpreted that the Mermentau river was flowing more eastward during the Wisconsinan, occupying the location of our study and was then diverted to the west as a result of coastal processes and the development of the Chenier plains. Also, the Mermentau was re-occupying almost the same location at different lowstands, and only when the Chenier formed (due to reactivation of the west Mississippi lobe), the Mermentau was deviated westward due to sediment accumulation at the shoreline.

    The obesity epidemic is producing growing interest in public policy measures targeting prevention. We developed a printed survey suitable for mailing to primary care physicians in Louisiana. Questions were asked concerning health policies relating to motorcycle helmet use, smoking, and obesity. We also obtained personal data, including type of practice, gender, age, ethnicity, personal income, height, and weight. Of 993 surveys mailed, there were 218 responses: 74% were male, 55% were from East Baton Rouge parish, an urban location, and 84% had an income of > dollar 100,000. Of respondents, 74% strongly agreed with helmet laws, 73% strongly agreed with limitations on smoking spaces and 62% strongly agreed with cigarette taxation. Concerning health policies related to obesity prevention, strongest support was for school concession policies, with 73% reporting strong agreement or agreement. There was support for regulating food advertisements, where 60% agree or strongly agree. However, only 29% agree or strongly agree with the taxing of unhealthy foods, compared to 78% of respondents favoring cigarette taxation, a statistically significant difference (< 0.0001). Support was particularly weak for governmental involvement in obesity discrimination, with only 16% of respondents agreeing or strongly agreeing. Political response to the obesity epidemic is only now emerging. However, our survey indicates that support among Louisiana physicians for obesity-related policy is not equal to support for policies directed against helmet and smoking laws. PMID:15751907

    This report documents the US Nuclear Regulatory Commission (NRC) staff review and safety evaluation of the Louisiana Energy Services, L.P. (LES, the applicant) application for a license to possess and use byproduct, source, and special nuclear material and to enrich natural uranium to a maximum of 5 percent U-235 by the gas centrifuge process. The plant, to be known as the Claiborne Enrichment Center (CEC), would be constructed near the town of Homer in Claiborne Parish, Louisiana. At full production in a given year, the plant will receive approximately 4,700 tonnes of feed UF{sub 6} and produce 870 tonnes of low-enriched UF{sub 6}, and 3,830 tonnes of depleted UF{sub 6} tails. Facility construction, operation, and decommissioning are expected to last 5, 30, and 7 years, respectively. The objective of the review is to evaluate the potential adverse impacts of operation of the facility on worker and public health and safety under both normal operating and accident conditions. The review also considers the management organization, administrative programs, and financial qualifications provided to assure safe design and operation of the facility. The NRC staff concludes that the applicant`s descriptions, specifications, and analyses provide an adequate basis for safety review of facility operations and that construction and operation of the facility does not pose an undue risk to public health and safety.

    A retrospective chart review was conducted to detect patients with sarcoidosis seen by pediatric rheumatology service from the period of 1992 to 2013 at Children's hospital of New Orleans. Twenty-seven patients were identified. The average duration of symptoms before diagnosis was 5 (range 1-120) months. Five patients had onset before the age of 5 years and were diagnosed with early-onset sarcoidosis. The most common manifestations at presentation were constitutional symptoms (62 %) followed by ocular (38 %). During the course of illness, 19/27 (70 %) had multiorgan involvement. Common manifestations included uveitis/iritis (77 %), fever (50 %), hilar adenopathy (42 %), arthritis (31 %), peripheral lympadenopathy (31 %), hepatosplenomegaly (31 %), parenchymal lung disease (27 %), and skin rash (19 %). Unusual manifestations included granulomatous bone marrow disease (3 cases), hypertension (2), abdominal aortic aneurysm (large vessel vasculitis; 1), granulomatous hepatitis (1), nephrocalcinosis (1), membranous nephropathy (1), refractory granulomatous interstitial nephritis with recurrence in transplanted kidney (1), CNS involvement (2), parotid gland enlargement (1), and sensorineural hearing loss (1). Biopsy specimen was obtained in 21/27 (77 %) patients, and demonstration of noncaseating granuloma associated with negative stains for mycobacteria and fungi was seen in 18 patients. Elevated angiotensin-converting enzyme level was seen in 74 % of patients. Treatment with oral prednisone was initiated in symptomatic patients with significant clinical improvement. Low-dose methotrexate (MTX) 10-15 mg/m(2)/week orally, as steroid-sparing agent, was administered in 14 patients. Other immunomodulators included cyclophosphamide (2 patients), etanercept (2), infliximab (2), mycophenolate mofetil (1), and tacrolimus (1). Childhood sarcoidosis is prevalent in Louisiana. Most of the affected children present with a multisystem disease associated with

  10. Satellite Images and Aerial Photographs of the Effects of Hurricanes Katrina and Rita on Coastal Louisiana

    Science.gov (United States)

    2007-01-01

    Introduction Hurricane Katrina made landfall on the eastern coastline of Louisiana on August 29, 2005; Hurricane Rita made landfall on the western coastline of Louisiana on September 24, 2005. Comparison of Landsat Thematic Mapper (TM) satellite imagery acquired before and after the landfalls of Katrina and Rita and classified to identify land and water demonstrated that water area increased by 217 mi2 (562 km2) in coastal Louisiana as a result of the storms. Approximately 82 mi2 (212 km2) of new water areas were in areas primarily impacted by Hurricane Katrina (Mississippi River Delta basin, Breton Sound basin, Pontchartrain basin, and Pearl River basin), whereas 99 mi2 (256 km2) were in areas primarily impacted by Hurricane Rita (Calcasieu/Sabine basin, Mermentau basin, Teche/Vermilion basin, Atchafalaya basin, and Terrebonne basin). Barataria basin contained new water areas caused by both hurricanes, resulting in some 18 mi2 (46.6 km2) of new water areas. The fresh marsh and intermediate marsh communities' land areas decreased by 122 mi2 (316 km2) and 90 mi2 (233.1 km2), respectively, and the brackish marsh and saline marsh communities' land areas decreased by 33 mi2 (85.5 km2) and 28 mi2 (72.5 km2), respectively. These new water areas represent land losses caused by direct removal of wetlands. They also indicate transitory changes in water area caused by remnant flooding, removal of aquatic vegetation, scouring of marsh vegetation, and water-level variation attributed to normal tidal and meteorological variation between satellite images. Permanent losses cannot be estimated until several growing seasons have passed and the transitory impacts of the hurricanes are minimized. The purpose of this study was to provide preliminary information on water area changes in coastal Louisiana acquired shortly after the landfalls of both hurricanes (detectable with Landsat TM imagery) and to serve as a regional baseline for monitoring posthurricane wetland recovery.

  12. Energy measures report: summary for English town and parish councils

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2007-09-15

    This report is a summary of information for English town and parish councils on measures local authorities in England and Wales can take to improve energy efficiency, increase the levels of microgeneration, reduce greenhouse gas emissions and reduce fuel poverty. It highlights the main areas in which local authorities can take action. In October 2006, the Stern Review of the economics of climate change was published. This assessed the evidence on the impacts of climate change and on the economic costs. Local authorities are uniquely placed to act on climate change mitigation and to alleviate fuel poverty. They can take action on their own estates and housing stock but can also play a key role in motivating the wider community to take action, based on their understanding of local priorities, risks and opportunities. Local authorities already have a number of responsibilities to incorporate climate change and energy policy considerations into the way in which they carry out their powers and functions. The publication of the Local Government White Paper 2006 signalled a shift in the role of local authorities. Tackling climate change is now recognised as one of the key areas in which local authorities can take on a community leadership role. The new performance framework, detailed in the White Paper, will have an appropriate focus on climate change, with the 2007 Comprehensive Spending Review making decisions on national outcomes, indicators and any national targets. The Review concluded that there is still time to avoid the worst impacts of climate change, if action is taken now and in concert with other countries. A key conclusion was that in the long term the cost of inaction would be far higher than the cost of tackling climate change now. The Government's view is therefore that taking action to mitigate the effects of climate change is the only strategy consistent with long-term economic growth and global stability. See URN: 07/1439 for the main report.

  14. The Louisiana State University waste-to-energy incinerator

    Science.gov (United States)

    1994-10-01

    This proposed action is for cost-shared construction of an incinerator/steam-generation facility at Louisiana State University under the State Energy Conservation Program (SECP). The SECP, created by the Energy Policy and Conservation Act, calls upon DOE to encourage energy conservation, renewable energy, and energy efficiency by providing Federal technical and financial assistance in developing and implementing comprehensive state energy conservation plans and projects. Currently, LSU runs a campus-wide recycling program in order to reduce the quantity of solid waste requiring disposal. This program has removed recyclable paper from the waste stream; however, a considerable quantity of other non-recyclable combustible wastes are produced on campus. Until recently, these wastes were disposed of in the Devil's Swamp landfill (also known as the East Baton Rouge Parish landfill). When this facility reached its capacity, a new landfill was opened a short distance away, and this new site is now used for disposal of the University's non-recyclable wastes. While this new landfill has enough capacity to last for at least 20 years (from 1994), the University has identified the need for a more efficient and effective manner of waste disposal than landfilling. The University also has non-renderable biological and potentially infectious waste materials from the School of Veterinary Medicine and the Student Health Center, primarily the former, whose wastes include animal carcasses and bedding materials. Renderable animal wastes from the School of Veterinary Medicine are sent to a rendering plant. Non-renderable, non-infectious animal wastes currently are disposed of in an existing on-campus incinerator near the School of Veterinary Medicine building.

    2013-01-01

    A study of West Nile virus (WNV) ecology was conducted in St. Tammany Parish, Louisiana, from 2002 to 2004. Mosquitoes were collected weekly throughout the year using Centers for Disease Control and Prevention (CDC) light traps placed at 1.5 and 6 m above the ground and gravid traps. A total of 379,466 mosquitoes was collected. WNV was identified in 32 pools of mosquitoes comprising four species; 23 positive pools were from Culex nigripalpus collected during 2003. Significantly more positive pools were obtained from Cx. nigripalpus collected in traps placed at 6 m than 1.5 m that year, but abundance did not differ by trap height. In contrast, Cx. nigripalpus abundance was significantly greater in traps placed at 6 m in 2002 and 2004. Annual temporal variation in Cx. nigripalpus peak seasonal abundance has important implications for WNV transmission in Louisiana. One WNV-positive pool, from Cx. erraticus, was collected during the winter of 2004, showing year-round transmission. The potential roles of additional mosquito species in WNV transmission in southeastern Louisiana are discussed.

    2009-12-01

    NSF and the Shell Foundation sponsor a program called Louisiana Undergraduate Recruitment and Geoscience Education (LaURGE). Goals of LaURGE are: 1) Interweave geoscience education into the existing curriculum; 2) Provide teachers with lesson plans that promote interest in geoscience, critical thinking by students, and are consistent with current knowledge in geoscience; and 3) Provide teachers with supplies that make these lessons the highlights of the course. Biology workshops were held at LSU in Baton Rouge and Centenary College in Shreveport in July 2009. 25 teachers including 5 African-Americans attended the workshops. Teachers were from public and private schools in seven different parishes. Teacher experience ranged from 3 years to 40 years. Courses impacted are Biology, Honors Biology, AP Biology, and Environmental Science. The workshops began with a field trip to Mississippi to collect fossil shark teeth and create a virtual field trip. After the field trip, teachers do a series of activities on fossil shark teeth to illustrate evolution and introduce basic concepts such as geologic time, superposition, and faunal succession. Teachers were also given a $200 budget from which to select fossils for use in their classrooms. One of our exercises explores the evolution of the megatoothed shark lineage leading to Carcharocles megalodon, the largest predatory shark in history with teeth up to 17 cm long. Megatoothed shark teeth have an excellent fossil record and show continuous transitions in morphology from the Eocene to Pliocene. We take advantage of the curiosity of sharks shared by most people, and allow teachers to explore the variations among different shark teeth and to explain the causes of those variations. Objectives are to have teachers (and their students): 1) sort fossil shark teeth into biologically reasonable species; 2) form hypotheses about evolutionary relationships; and 3) describe and interpret evolutionary trends in the fossil Megatoothed

    The U.S. Environmental Protection Agency (EPA) developed the RE-Powering America's Land initiative to re-use contaminated sites for renewable energy generation when aligned with the community's vision for the site. The former Kaiser Aluminum Landfill in St. Bernard Parish, Louisiana, was selected for a feasibility study under the program. Preliminary work focused on selecting a biomass feedstock. Discussions with area experts, universities, and the project team identified food wastes as the feedstock and anaerobic digestion (AD) as the technology.

  11. Louisiana Air Quality - Using ASTER, Landsat 5, and MODIS to Assess the Impact of Sugar Cane and Marsh Burning Practices on Local Air Quality

    Biomass burning is an event that occurs globally and encompasses both human-initiated and naturally-occurring fires. It is estimated that 3 billion metric tons of biomass are burned every year worldwide (Curtis 2002). Societies have used these burning techniques for cooking and heating, clearing land for agricultural use, and removing excess biomass from grazing and croplands (Levine 1991). Our study focuses on the state of Louisiana and its commonly occurring methods of sugarcane and marsh biomass burning (LSU Ag.Center 2000; Nyman and Chabreck 1995). Over the centuries, the sugarcane industry in this state has steadily grown to surpass all other agriculture commodities. To promote efficiency within this large industry, burning excess biomass takes place throughout the harvesting period (LSU Ag.Center 2000). In addition to sugarcane, Louisiana contains 30% of the total coastal marsh of the United States (LSU Ag.Center 2000). The periodic burning of such marshes is an ecologically important management tool that is practiced throughout the Atlantic and Gulf Coasts (Nyman and Chabreck 1995). In most biomass burning instances, the leading by-product is particulate matter that is less than 10 microns in diameter (PM10). Through past research, this fine material has been shown to have negative health effects on surrounding populations (Boopathy2001). While burning guidelines have been set into place by the Louisiana Department of Agriculture and Forestry (LDAF) to reduce health effects, the guidelines are voluntary (LDAF 2000). To help quantify emission estimates, we will focus on Iberia Parish for sugarcane burning and Cameron Parish for marsh burning. Through analysis of ASTER, Landsat 5 TM, and MODIS data, our goal is to determine the amount and location of land area burned for the years 2008 and 2009 due to these practices. With emissions algorithms from Seiler and Crutzen, 1980, total acreage burned can be used to estimate emissions. This information will help to

    A large deficit in the coastal sediment budget, high rates of relative sea-level rise (???0.9 cm/year), and storm-induced current and wave erosion are forcing barrier shoreface retreat along the periphery of the Mississippi River delta plain. Additionally, conversion of interior wetlands to open water has increased the bay tidal prism, resulting in degradation of barrier islands due to inlet widening, formation of new inlets, and sediment sequestration at ebb-tidal deltas. Single-beam bathymetric surveys along a 165-km stretch of south-central Louisiana barrier coast, from Raccoon Point in Terrebonne Parish to Sandy Point in Plaquemines Parish, were conducted in 2006. These data, combined with historical bathymetry from three time periods (dating to the 1880s), provide a series of digital elevation models that were used to calculate sediment volumetric changes and determine long-term erosional-depositional trends. Dominant patterns during the 125-year period include (1) erosion of ???1.6????????109 m3 from the shoreface, forcing up to 3 km of shoreface retreat, (2) sediment deposition in coastal bights and at ebb-tidal deltas, and (3) a combined increase in tidal inlet cross-sectional area from ???41,400 m2 to ???139,500 m 2. Bathymetric and shoreline change datasets separated by shorter time periods (sub-annual) demonstrate that these long-term trends are driven by processes associated with major hurricane impacts, and that rates of shoreface erosion are an order of magnitude greater during active hurricane seasons compared to long-term trends. ?? 2009 Springer-Verlag.

  14. St. Bernard Parish : la crise d’un territoire suburbain St. Bernard Parish, the crisis of a suburban territory

    Full Text Available Situé à l’est de La Nouvelle-Orléans, St. Bernard Parish est l’un des territoires les plus vulnérables au risque d’ondes de tempêtes de toute la région métropolitaine. Après avoir été ravagée par le cyclone Katrina en 2005, St. Bernard peine à se redresser et montre le plus faible niveau de reprise de toute la région du Golfe du Mexique frappée par Katrina. De plus, la reconstruction est freinée par des polémiques virulentes qui nous rappellent les pires années des tensions raciales des années 1960. Cet article s’intéresse aux relations supposées entre les fragmentations urbaines et la faculté d’adaptation aux risques naturels. L’étude du cas de St. Bernard illustre la force d’inertie des territoires et comment de vieilles querelles ville-banlieue affaiblissent la résilience urbaine.Located east of New Orleans, St. Bernard Parish is one of the most vulnerable parts of the greater New Orleans metropolitan area to storm surges. After having been devastated by Hurricane Katrina in 2005, St. Bernard still struggles to recover from the storm, and displays the lowest recovery level of the entire Katrina-hit Gulf Coast area so far. Moreover, reconstruction is hampered by loud polemics that remind us of the worst years of racial polarization during the 1960’s. This paper explores the possible linkage between urban fragmentations and adaptive capacity to natural hazard. The St. Bernard case-study illustrates the strength of path dependency, and how long-entrenched suburb-central city mistrust hampers urban resilience.

    International Nuclear Information System (INIS)

    The Final Environmental Impact Statement (FEIS) (Volume 1), was prepared by the Nuclear Regulatory Commission (NRC) in accordance with regulation 10 CFR Part 51, which implements the National Environmental Policy Act (NEPA), to assess the potential environmental impacts for licensing the construction and operation of a proposed gaseous centrifuge enrichment facility to be built in Claiborne Parish, Louisiana by Louisiana Energy Services, L.P. (LES). The proposed facility would have a production capacity of about 866 metric tons annually of up to 5 weight percent enriched UF6, using a proven centrifuge technology. Included in the assessment are co on, both normal operations and potential accidents (internal and external events), and the eventual decontamination and decommissioning of the site. In order to help assure that releases from the operation of the facility and potential impacts on the public are as low as reasonably achievable, an environmental monitoring program was developed by LES to detect significant changes in the background levels of uranium around the site. Other issues addressed include the purpose and need for the facility, the alternatives to the proposed action, potential disposition of the tails, the site selection process, and environmental justice. The NRC staff concludes that the facility can be constructed and operated with small and acceptable impacts on the public and the environment, and proposes to issue a license to the applicant, Louisiana Energy Services, to authorize construction and operation of the proposed facility. The letters in this Appendix have been divided into three sections. Section One contains letters to which the NRC responded by addressing specific comments. Section Two contains the letters that concerned the communities of Forest Grove and Center Springs. Section Three is composed of letters that required no response.

  2. Tremors in the Bayou: The Events on the Napoleonville Salt Dome, Louisiana

    Science.gov (United States)

    Ellsworth, W. L.; Horton, S.; Benz, H.; Hickman, S.; Leeds, A.; Leith, W. S.; Meremonte, M.; Rubinstein, J. L.; Withers, M. M.; Herrmann, R. B.

    2012-12-01

    Beginning in early June, 2012, an extended series of earth tremors were reported by residents of Bayou Corne in Assumption Parish, Louisiana, and at well control facilities on the nearby Napoleonville salt dome. The salt dome contains numerous caverns resulting from solution mining; some are used to store LPG and natural gas while others produce saltwater brine. Residents also reported natural gas bubbling at nearby locations in Bayou Corne and Grand Bayou. Some of the tremors were large enough to produce "cracks in sheet rock and foundations" (The Advocate, Baton Rouge, July 5, 2012). It was thus quite surprising to find that no earthquakes were detected in this region by either the USGS NEIC or the USArray Array Network Facility despite the presence of Transportable Array station 544A only 10 km from Bayou Corne. Careful inspection of the seismograms at 544A did reveal multiple events characterized by virtually no body wave energy and strong surface waves at the times of reported tremors. In response to a request for assistance from the State of Louisiana six temporary seismic stations with Trillium broad band sensors were deployed in the immediate epicentral region by the USGS and University of Memphis starting on July 12. Seismograms recorded by the temporary stations revealed a variable rate of tremor activity, with several hundred events registered on active days. Even at very close distance (S-P < 0.5 s) the body waves are weak and surface waves prominent, indicating a very shallow source depth. Precise location of the events is complicated by the presence of the high-seismic velocity and steep-sided Napoleonville salt dome that reaches to within 220 m of the surface and is overlain and surrounded by very low velocity sediments. Following several repositionings of the seismic network we have determined that the source region lies on the western edge of the salt dome top at very shallow depth and in the vicinity of an abandoned brine supply cavern.

    The Dow/D.O.E. L. R. Sweezy No. 1 geopressured geothermal production well was completed in August of 1981. The well was perforated and gravel packed in approximately 50 feet of sand from 13,344 feet to 13,395 feet. Permeabilities of 6 to 914 millidarcies were measured with porosity of 25 to 36%. Static surface pressure after well clean-up was 5000 psi. At 1000 B/D flow rate the drawdown was 50 psi. The water produced in clean-up contained 100,000 ppm TDS. This report details the plan for testing this well with the goal of obtaining sufficient data to define the total production curve of the small, 939 acre, reservoir. A production time of six to nine months is anticipated. The salt water disposal well is expected to be completed and surface equipment installed such that production testing will begin by April 1, 1982. The program should be finished and reports written by February 28, 1983. The brine will be produced from the No.1 well, passed through a separator where the gas is removed, then reinjected into the No.2 (SWD) well under separator pressure. Flow rates of up to 25,000 B/D are expected. The tests are divided into a two-week short-term test and six to nine-month long-term tests with periodic downhole measurement of drawdown and buildup rates. Data obtained in the testing will be relayed by phoneline computer hookup to Otis Engineering in Dallas, Texas, where the reservoir calculations and modeling will be done. At the point where sufficient data has been obtained to reach the objectives of the program, production will be ended, the wells plugged and abandoned, and a final report will be issued.

  19. 'Indiscriminate liberality subverts the Morals and depraves the habits of the Poor': A Contribution to the Debate on the Poor Law, Parish Clothing Relief and Clothing Societies in Early Nineteenth-Century England

    OpenAIRE

    2009-01-01

    Recently in Textile History, Peter Jones noted the great quantity of parish clothing provision in early nineteenth-century England, even beyond the new Poor Law of 1834. But evidence from Sussex and Kent shows that here parish clothing provision sharply declined well before 1834 specifically to reduce poor relief spending. Furthermore, the Commissioners charged with implementing the 1834 Act sought expressly to outlaw parish clothing relief. In the south, but rarely in the north, self-help cl...

    Rainey, J M; Groves, F D; DeLeon, I R; Joubert, P E

    1990-06-01

    Water samples were obtained from 128 private water wells surrounding eight oil field waste sites in Vermilion Parish. The specimens were analyzed for five heavy metals: barium, arsenic, chromium, lead, and cadmium. Half of the specimens were then analyzed for 16 volatile organic compounds. A blood sample was obtained from healthy adults drinking water from the wells tested for volatile organic compounds and this blood sample was also analyzed for volatile organic compounds. None of the water samples had levels of heavy metals or volatile organic compounds that exceeded the National Primary Drinking Water Standards. Barium levels in excess of 250 parts per billion suggested that styrene, toluene, and chloroform might be present. Blood levels of volatile organic compounds were significantly higher than could be accounted for by water consumption with levels in smokers significantly higher than in nonsmokers. These data suggest that as yet there is no contamination of ground water supplies around these sites. Volatile organic accumulation in humans probably occurs from a respiratory rather than from an oral route. PMID:2362163

  1. Geopressured-geothermal well activities in Louisiana

    International Nuclear Information System (INIS)

    Since September 1978, microseismic networks have operated continuously around US Department of Energy (DOE) geopressured-geothermal well sites to monitor any microearthquake activity in the well vicinity. Microseismic monitoring is necessary before flow testing at a well site to establish the level of local background seismicity. Once flow testing has begun, well development may affect ground elevations and/or may activate growth faults, which are characteristic of the coastal region of southern Louisiana and southeastern Texas where these geopressured-geothermal wells are located. The microseismic networks are designed to detest small-scale local earthquakes indicative of such fault activation. Even after flow testing has ceased, monitoring continues to assess any microearthquake activity delayed by the time dependence of stress migration within the earth. Current monitoring shows no microseismicity in the geopressured-geothermal prospect areas before, during, or after flow testing

    In May 2002, 15 wells and four surface water sites were sampled, and in September 2002, those same wells and sites plus four additional surface sites were sampled in five parishes of northwestern Louisiana. A geographic information system (GIS) was used to select residential water wells for sampling. Well water samples were analyzed for pH, conductivity, organic compounds, and nutrient and anion concentrations. All samples were further tested for presence of fungi (maintained for up to 28 days and colonies counted and identified microscopically), and metal and trace element concentration by inductively-coupled plasma mass spectrometry and atomic emission spectrometry. Surface water samples were tested for dissolved oxygen and evidence of leptospiral bacterial presence. A polymerase chain reaction protocol was optimized for detection of pathogenic leptospires, and the sensitivity of the assay was determined. The Spearman correlation method was used to assess the association between the endpoints for these field/laboratory analyses and the incidence of cancer of the renal pelvis obtained from the Louisiana Tumor Registry. Significant associations were revealed between the cancer rate and the overall number of organic compounds, the fungi Zygomycetes, the nutrients PO4 and NH3, and thirteen chemical elements (As, B, Br, Cl, Cr, F, Li, Na, P, Rb, Se, Sr, W) from the well water as compared to the controls. Among the species of fungi from the total of 136 isolates were 12 Penicillium spp., at least two Aspergillus spp., a number of other genera (Alternaria sp., Eupenicillium lapidosum, Cladosporium sp., Epicoccum sp., Trichoderma sp., Paecilomyces sp., Chrysosporium sp., Chloridium sp.), and Zygomycetes, and Coelmycetes -- some of which are known mycotoxin producers. The two control wells yielded a mean of 6.5 (SD = 3.5355) individual isolates, while the mean number of isolates from all other sites was 7.6 (SD = 4.4866). Presence of human pathogenic leptospires was

    Noroviruses are the most common causative agent of viral gastroenteritis in humans, and are responsible for major foodborne illnesses in the United States. Filter-feeding molluscan shellfish exposed to sewage-contaminated waters bioaccumulate viruses, and if consumed raw, transmit the viruses to humans and cause illness. We investigated the occurrence of norovirus GI and GII and microbial indicators of fecal contamination in the eastern oysters (Crassostrea virginica) and water from commercial harvesting areas along the Louisiana Gulf Coast (January to November of 2013). Microbial indicators (aerobic plate count, enterococci, fecal coliforms, Escherichia coli, male-specific coliphages, and somatic coliphages) were detected at the densities lower than public health concerns. Only one oyster sample was positive for norovirus GII at 3.5 ± 0.2 log10 genomic equivalent copies/g digestive tissues. A stool specimen obtained from an infected individual associated with a norovirus outbreak and the suspected oysters (Cameron Parish, La., area 30, January 2013) were also analyzed. The norovirus strain in the stool belonged to GII.4 Sydney; however, the oysters were negative and could not be linked. In general, no temporal trend was observed in the microbial indicators. Low correlation among bacterial indicators was observed in oysters. Strongest correlations among microbial indicators were observed between enterococci and fecal coliforms (r = 0.63) and between enterococci and E. coli (r = 0.64) in water (P 0.05). Our results emphasize the need for regular monitoring of pathogenic viruses in commercial oyster harvesting areas to reduce the risks of viral gastroenteritis incidences. PMID:25899121

    In 2010, the Deepwater Horizon (DWH) oil spill adversely impacted many communities along the Gulf of Mexico. Effects on Gulf waters, marshes, aquatic life, and fisheries were evident in the following days, months, and years. Through studying affected communities' perceptions regarding the DWH accident, we aim to identify behavioral changes, understand public information sources, and inform dissemination strategies that improve communications from regulatory agencies. Over a three-year period (2012-2015), residents (n = 192) from 7 coastal parishes in southeast Louisiana were surveyed about their perceptions and behaviors before, during, and after the DWH accident. Self-reported consumption of local seafood decreased significantly (50%) during the DWH oil spill but returned to pre-event reported levels by 2015. However, negative seafood quality perceptions remain and have not returned to what were generally positive pre-event levels. Over 30% of study participants trust relatives, friends, and neighbors more than government officials or scientists as information sources regarding locally harvested seafood. Importantly, nearly 50% of participants report that they lack the information needed to make informed decisions regarding the safety of consuming local seafood. We conclude that a lack of information and trust in government agencies exacerbated negative perceptions of oil spill-related dangers. In some cases, overestimation of perceived dangers likely led to behavioral modifications that persist today. Efforts should be made to improve relationships between public health agencies and communities in order to properly inform all citizens of risks following environmental disasters. PMID:27289418

    In 2010, the Deepwater Horizon (DWH) oil spill adversely impacted many communities along the Gulf of Mexico. Effects on Gulf waters, marshes, aquatic life, and fisheries were evident in the following days, months, and years. Through studying affected communities' perceptions regarding the DWH accident, we aim to identify behavioral changes, understand public information sources, and inform dissemination strategies that improve communications from regulatory agencies. Over a three-year period (2012-2015), residents (n = 192) from 7 coastal parishes in southeast Louisiana were surveyed about their perceptions and behaviors before, during, and after the DWH accident. Self-reported consumption of local seafood decreased significantly (50%) during the DWH oil spill but returned to pre-event reported levels by 2015. However, negative seafood quality perceptions remain and have not returned to what were generally positive pre-event levels. Over 30% of study participants trust relatives, friends, and neighbors more than government officials or scientists as information sources regarding locally harvested seafood. Importantly, nearly 50% of participants report that they lack the information needed to make informed decisions regarding the safety of consuming local seafood. We conclude that a lack of information and trust in government agencies exacerbated negative perceptions of oil spill-related dangers. In some cases, overestimation of perceived dangers likely led to behavioral modifications that persist today. Efforts should be made to improve relationships between public health agencies and communities in order to properly inform all citizens of risks following environmental disasters.

  19. Louisiana Story, entre nature et cultures

    Directory of Open Access Journals (Sweden)

    2001-12-01

    Full Text Available Dans Louisiana Story, Robert Flaherty a choisi l'opulente nature louisianaise comme lieu de rencontre entre deux cultures: une culture industrielle anglophone et une culture rurale francophone. Ce film, qui est commandé et financé par la compagnie pétrolière Standard Oil devait à l'origine montrer les difficultés et les dangers de l'extraction pétrolière pour ses équipes tout en les mettant en scène dans une réalisation destinée au grand public. Le problème posé à Flaherty était que de telles manœuvres étaient souterraines, qu'elles échappaient à l'objectif de la caméra. Après avoir parcouru des milliers de kilomètres aux Etats-Unis à la recherche de l'inspiration, son choix se porta sur le pays des Acadiens de Louisiane où il fut marqué par l'image d'une plate-forme se déplaçant par voie d'eau sur l'un des multiples bayous de cette région. Ce lieu lui permettait de mêler et de confronter dans la même image la modernité des derricks et une nature sauvage, une population étrange par ses traditions et son langage à une population ouvrière plus typiquement américaine. Louisiana Story reste un film étrange et ambigu. Les hommes y apparaissent secondaires dominés par le gigantisme des équipements pétroliers et la grandeur de la nature. Il semble que lors du tournage Flaherty ait été fasciné par la faune et la flore au détriment du scénario qui était la rencontre entre deux cultures à travers les découvertes et les liens d'amitié d'un petit garçon cajun.

  20. Coastal Prairie Restoration Information System: Version 1 (Louisiana)

    Science.gov (United States)

    Allain, Larry

    2007-01-01

    The Coastal Prairie Restoration Information System (CPR) is a Microsoft Access database that allows users to query and view data about Louisiana coastal prairie species. Less than 0.1% of Louisiana's coastal prairie vegetation remains in a relatively undisturbed condition. Encompassing as much as 1 million hectares of land, coastal prairie is a hybrid of coastal wetlands and tall grass prairie. Over 550 plant species have been identified in Louisiana's coastal prairies to date. Efforts to conserve and restore this endangered ecosystem are limited by the ability of workers to identify and access knowledge about this diverse group of plants. In this database, a variety of data are provided for each of 650 coastal prairie species in Louisiana. The database was developed at the U.S. Geological Survey National Wetlands Research Center by Larry Allain, with software development by Myra Silva. Additional funding was provided by the biology department of the University of Louisiana at Lafayette (ULL), the ULL Center for Environmental and Ecological Technology, and the National Science Foundation.

    Anderson, Julie A; Alford, Amy B

    2014-02-15

    Derelict crab traps impact the coastal ecosystem through continued catch of target species and species of conservation, economic, or recreational importance. During volunteer-supported crab trap cleanups in 2012 and 2013, we quantified ghost fishing activity in derelict crab traps in coastal Louisiana through a citizen scientist program. Volunteers removed 3607 derelict traps during these events, and over 65% of traps analyzed by citizen scientists were actively ghost fishing. Additionally, volunteers identified 19 species enmeshed in derelict traps, including a combination of fresh and saltwater species. We also detected a significant difference in the number of blue crab in actively ghost fishing derelict traps across removal locations with estimated catches varying between 2.4 and 3.5 crabs/trap. Our instantaneous estimates of ghost fishing activity are greater than those previously thought in Louisiana, further justifying current derelict crab trap prevention and removal extension and outreach programs in Louisiana and throughout the Gulf of Mexico.

    Zhang, H.; Guo, H.

    2015-12-01

    Wet deposition and dry deposition reduce their concentrations of sulfur and nitrogen contained air pollutants in atmosphere, but lead to increase of sulfur and nitrogen fluxes to the surface. Atmospheric deposition of sulfur and nitrogen can lead to acidification of surface water bodies (lakes, rivers, and coasts) and subsequent damage to aquatic ecosystems as well as damage to forests and vegetation. Louisiana has abundant water resources with approximately 11% of the total surface area composed of water bodies. It is important to protect water resources from excessive atmospheric deposition of sulfur and nitrogen. However, the information obtained from the observation systems for understanding the deposition of sulfur and nitrogen and the adverse effects in Louisiana is limited. This study uses a source-oriented CMAQ model to simulate emission, formation, transport, and deposition of sulfur and nitrogen species in Louisiana. WRF is used to generate the meteorological inputs and SMOKE is used to generate the emissions based on national emission inventory (NEI). The forms and quantities of sulfur and nitrogen deposition from wet and dry processes in Louisiana will be discovered. The spatial and temporal variations of sulfur and nitrogen fluxes will be quantified and contributions of major source sectors or source regions will be quantified.

    2010-01-01

    NASA Stennis Space Center, located in Mississippi, USA, undertook an archaeological survey of the southeastern Louisiana marshes beginning in 2003. Progress on this activity was severely hampered by the 2005 hurricane season when both Katrina and Rita devastated the study area. In 2008, the NASA team reinitiated the analysis of the project data and that work continues today. The project was conducted initially in partnership with the U.S. Army, Corps of Engineers New Orleans District and Tulane University. NASA and its partners utilized a wide variety of satellite and airborne remote sensing instruments combined with field verification surveys to identify prehistoric archeological sites in the Southeastern Louisiana delta, both known and still undiscovered. The main approach was to carefully map known sites and use the spectral characteristics of these sites to locate high probability targets elsewhere in the region. The archaeological activities were conducted in support of Coast 2050 whose stated goals is to sustain and restore a coastal ecosystem that supports and protects the environment, economy and culture of southern Louisiana. As the Coast 2050 report states: [T]he rate of coastal land loss in Louisiana has reached catastrophic proportions. Within the last 50 years, land loss rates have exceeded 40 square miles per year, and in the 1990's the rate has been estimated to be between 25 and 35 square miles each year. This loss represents 80% of the coastal wetland loss in the entire continental United States.

  1. Source targeting tar balls along the southern Louisiana coastline

    International Nuclear Information System (INIS)

    Stranded oil and tarballs deposited along the southern coast of Louisiana were source targeted, or compared for petroleum similarities, during 1992. The distribution, frequency, and composition of the stranded oil was assessed for specific study sites covering about 200 miles of the Louisiana coastline. Petroleum transportation off Louisiana shores is in the millions of barrels; with the Louisiana Offshore Oil Port receiving more than 200 million barrels per year. Also contributing to this transportation system are the outer continental shelf production activities, transporting 98 percent of their production by pipeline and 2 percent by barge. The questions addressed here are: What are the sources of the stranded oil and tar found upon the beaches? Are they primarily from small unrelated events, or are they from chronic discharges of identifiable sources? Preliminary data indicates a wide range of petroleum sources, with bunker oils most abundant. The petroleum has undergone varying degrees of weathering, or degradation by environmental processes. Preliminary data indicate relatively undegraded as well as extremely degraded petroleum, with no apparent correlation with study stations. Stations selected along the coastline were biannually surveyed, and petroleum samples collected were quantitatively assessed for petroleum per square meter per station. For a complete chemical assessment, the samples were qualitatively analyzed by detailed gas chromatography/mass spectrometry (GC/MS) characterization and source fingerprinting using selective ion monitoring (SIM). The results were plotted in a cluster matrix to highlight the number of possible sources and the chemical characteristics of the petroleum found

    2013-10-01

    Full Text Available The Parish Church of the Immaculate Conception of the Virgin Mary in Valpovo (1733–1736, exceptional both in its spatial organization and the design of its exterior, was constructed in specific circumstances in the aftermath of the liberation of Slavonia from the Ottoman occupation. The old lands of Valpovo, with the medieval fort of Morović, were, in accordance with the Habsburg politics, given as a feud to Baron Hilleprand by Charles VI. The baron initiated the construction of a monumental parish church on his estate by commissioning its design in Vienna, as evidenced by the rich archival material on Hilleprand's property housed at the State Archive in Osijek. In keeping with the provenance of its design, the church was built as a monumental structure consisting of a two-bay nave covered with domical vaults and flanked by a narrower semicircular groin-vaulted sanctuary and a facade belfry. The type represented by the church in Valpovo – single-aisled structure with two bays – was a sort of innovation by Johann Lucas von Hildebrandt, inspired by the famous church of San Fedele in Milan (1569 and often used by Hildebrandt in his own church projects built under the patronage of high Austrian nobility, such as the parish church in Seelowitz in Moravia (1722–27 with an integrated facade belfry, or the parish churches in Aspersdorf (1730, Stranzendorf (1733 and Großstelzendorf (1735–37. This architectural type was adopted and further developed by Hildebrandt's contemporaries, especially his immediate follower Franz Anton Pilgram, a Viennese architect whose design for the parish church in Münchendorf (1740 shows great similarity with the Valpovo church, both in its proportions and in the treatment of details. All this is hardly surprising if one keeps in mind the Viennese origin and the courtly status of the commissioner and donor of the parish church in Valpovo. It took more than two decades for the spatial features of this church to

  6. Hydrogeophysical Data Fusion and Geostatistical Approach to Characterize Hydrogeological Structure of the Baton Rouge Aquifer System in Louisiana

    Science.gov (United States)

    2012-12-01

    The complex siliciclastic aquifer system underneath the Baton Rouge area, Louisiana is fluvial in origin and is characterized by strongly binary heterogeneity of sandy units and mudstones as pervious and impervious hydrofacies. Two distinct east-west trending geologic faults, the Baton Rouge fault and the Denham Springs-Scotlandville fault, cut across East Baton Rouge Parish. Data from the USGS water wells suggest that the Baton Rouge fault is a low permeable fault that historically separates a sequence of freshwater aquifers north of the fault from brackish aquifers south of the fault. However, the Denham Springs-Scotlandville fault appears to be pervious. In this study we utilize wireline geophysical data and lithologic data to characterize the Baton Rouge aquifer system and delineate flow pathways thought the faults. To avoid non-uniqueness associated with the use of a single geophysical data type particularly with the presence of salinization, we interpret the sand and shale hydrofacies for each well log based on wireline short normal electrical resistivity, single-point resistance, spontaneous-potential and gamma ray. For geological model calibration we use lithologic data from drillers logs representing the actual lithology with depth. Using geophysical data for hydrogeological structure construction and using lithologic data for model calibration, we implement a generalized parameterization indicator scheme. First, we show that this methodology can effectively analyze a binary siliciclastic aquifer by depicting the spatial extent of major water bearing units, their interconnections and preferential flow paths within each unit. Second, mapping of the binary fault stratigraphy assists in the assessment of hydraulic continuity and saltwater intrusion in the siliciclastic aquifer system, which exhibits discontinuous heterogeneity due to fault throw. By juxtaposing sand units from both sides of the fault plane, horizontal flow pathways are identified if sands

    Full Text Available Mold and other allergen exposures exacerbate asthma symptoms in sensitized individuals. We evaluated allergen concentrations, skin test sensitivities, and asthma morbidity for 182 children, aged 4–12 years, with moderate to severe asthma, enrolled 18 months after Katrina, from the city of New Orleans and the surrounding parishes that were impacted by the storm, into the Head-off Environmental Asthma in Louisiana (HEAL observational study. Dust (indoor and air (indoor and outdoor samples were collected at baseline of 6 and 12 months. Dust samples were evaluated for dust mite, cockroach, mouse, and Alternaria by immunoassay. Air samples were evaluated for airborne mold spore concentrations. Overall, 89% of the children tested positive to ≥1 indoor allergen, with allergen-specific sensitivities ranging from 18% to 67%. Allergen concentration was associated with skin sensitivity for 1 of 10 environmental triggers analyzed (cat. Asthma symptom days did not differ with skin test sensitivity, and surprisingly, increased symptoms were observed in children whose baseline indoor airborne mold concentrations were below median levels. This association was not observed in follow-up assessments. The lack of relationship among allergen levels (including mold, sensitivities, and asthma symptoms points to the complexity of attempting to assess these associations during rapidly changing social and environmental conditions.

    The paper presents a brief survey of the state of medicine in the 18th century with an emphasis upon developments in France. In the early nineteenth century the emergence of the Paris Clinical School made France pre-eminent in medicine. Its leaders emphasized localism, correlated symptoms with postmortem reports, and introduced clinical statistics. They also introduced the stethoscope and the techniques of auscultation and palpation and were the first to recognize that excessive bloodletting, purging and other depletory measures were harmful. The French population in Louisiana continued to look to France for educational and intellectual leadership well into the nineteenth century, and the findings of the Paris Clinical School had an immediate impact upon Louisiana medicine, leading to a clash between the French-speaking physicians who emphasized moderation and good nursing and the English-speaking practitioners who believed in drastic intervention.

    Luckett, Brian G.; L. Joseph Su; Rood, Jennifer C.; Elizabeth T. H. Fontham

    2012-01-01

    Cadmium has been hypothesized to be a pancreatic carcinogen. We test the hypothesis that cadmium exposure is a risk factor for pancreatic cancer with a population-based case-control study sampled from a population with persistently high rates of pancreatic cancer (south Louisiana). We tested potential dietary and nondietary sources of cadmium for their association with urinary cadmium concentrations which reflect long-term exposure to cadmium due to the accumulation of cadmium in the kidney c...

  14. Land area change in coastal Louisiana from 1932 to 2010

    Science.gov (United States)

    2011-01-01

    Coastal Louisiana wetlands make up the seventh largest delta on Earth, contain about 37 percent of the estuarine herbaceous marshes in the conterminous United States, and support the largest commercial fishery in the lower 48 States. These wetlands are in peril because Louisiana currently undergoes about 90 percent of the total coastal wetland loss in the continental United States. Documenting and understanding the occurrence and rates of wetland loss are necessary for effective planning, protection, and restoration activities. The analyses of landscape change presented in this report use historical surveys, aerial data, and satellite data to track landscape changes. Summary data are presented for 1932-2010; trend data are presented for 1985-2010. These later data were calculated separately because of concerns over the comparability of the 1932 and 1956 datasets (which are based on survey and aerial data, respectively) with the later datasets (which are all based on satellite imagery). These analyses show that coastal Louisiana has undergone a net change in land area of about -1,883 square miles (mi2) from 1932 to 2010. This net change in land area amounts to a decrease of about 25 percent of the 1932 land area. Persistent losses account for 95 percent of this land area decrease; the remainder are areas that have converted to water but have not yet exhibited the persistence necessary to be classified as \\"loss.\\" Trend analyses from 1985 to 2010 show a wetland loss rate of 16.57 mi2 per year. If this loss were to occur at a constant rate, it would equate to Louisiana losing an area the size of one football field per hour. The use of 17 datasets plus the application of consistent change criteria in this study provide opportunities to better understand the timing and causal mechanisms of wetland loss that are critical for forecasting landscape changes in the future.

  15. Economic benefits or irradiation of molluscan shellfish in Louisiana

    International Nuclear Information System (INIS)

    Louisiana is traditionally the number one producer of shellstock oysters in the United States in America, averaging approximately 12 million pounds of meats per year over the last ten years. In the last few years, however, extensive press campaigns questioning the safety of domestic seafood, especially raw molluscan shellfish, have created national public concern. As a result, large retail buyers entirely stopped purchasing oysters in 1988, and some states decided to require warning labels on raw oyster products. To regain public confidence in the safety of products, the oyster industry in Louisiana and throughout the country is supporting research, development and education for irradiation processing technology, mainly to eliminate species of Vibrio bacterial from live or raw processed oysters. The current estimated added cost of US $0.05-$0.08/lb for large volume commercial irradiation would certainly be considered a cost beneficial value-added processing step to the oyster industry in Louisiana and the entire country. The incentive is to offer an even safer product to all consumers, and to regain public confidence and the large commercial markets. Oyster industry leaders predict that acceptance of this technology by the public would cause the market to rebuild to its former levels or higher within six months to a year. 15 refs, 4 figs, 4 tabs

  15. Information resources: How they are utilized by Louisiana

    International Nuclear Information System (INIS)

    Louisiana, now in a developmental stage of policy and planning, has completed a project aimed at reducing hazardous releases of air toxics in thee state. The state is also conducting a Comparative Risk Project and is using risk assessment practices to develop its waste quality standards. In developing an air toxic list, Louisiana incorporated four major criteria into the ranking: emission levels, human health effects, potential population exposure, and persistence or accumulation in the environment. For the human health effects criterion, data for each substance was gathered from numerous sources, although the Integrated Risk Information System (IRIS) database was used as a primary source for toxicological information. Following guidelines established by the Environmental Protection Agency (EPA), the Office of Water Resources, Water Pollution Control Division, has developed numerical criteria for human health protection based on risk assessment procedures in the 1989 Water Quality Standards Revision. Currently over 30 toxic substances have risk-based criteria for th protection of human health in the standards. Numerical criteria were calculated for carcinogenic substances having an EPA Classification of A, B1, B2, or C. Cancer class designations along with cancer potency slopes and reference doses were extracted from the IRIS database, with the exception of those chemicals that had not been assessed in IRIS as of December 1, 1988. The parameters necessary for calculating human health criteria for the missing chemicals were taken from 1980, 1984, and 1985 ambient water quality criteria documents: data on bioconcentration factors were included. Currently, Louisiana is working on a Comparative Risk Project, a ranking of the environmental issues in the state relative to potential risk to the public, which is the basis for a widespread 1991 public outreach effort

  18. Risk assessment for produced water discharges to Louisiana open bays

    Energy Technology Data Exchange (ETDEWEB)

    1995-11-01

    Potential human health and environmental impacts from discharge of produced water to the Gulf of Mexico concern regulators at the State and Federal levels, environmental interest groups, industry and the public. Current regulations in the United States require or propose azero discharge limit for coastal facilities based primarily on studies performed in low energy,poorly flushed environments. Produced water discharges in coastal Louisiana, however,include a number located in open bays, where potential and impacts are likely to be larger than the minimal impacts associated with offshore discharges, but smaller than those demonstrated in low-energy canal environments. This paper summarizes results of a conservative screening-level health and ecological assessment for contaminants discharged in produced water to open bays in Louisiana, and reports results of a probabilistic human health risk assessment for radium and lead. The initial human health and ecological risk assessments consisted of conservative screening analyses that identified potentially important contaminants and excluded others from further consideration. A more quantitative probabilistic risk assessment was completed for the human health effects of the two contaminants identified in this screen: radium and lead. This work is part of a series of studies on the health and ecological risks from discharges of produced water to the Gulf of Mexico, supported by the United States Department of Energy (USDOE).

  19. Parish school inspection as a means of implementation of the policy on Paraná’s provincial education (1853-1889

    Directory of Open Access Journals (Sweden)

    Maria Elisabeth Blanck Miguel

    2015-07-01

    Full Text Available This paper addresses the primary public inspection, particularly that exercised by parish inspectors, considered as one of the forms of manifestation of the policy on education. A research about reports and official letters concerning the primary public education in Paraná in the provincial period (1853-1889 shows ordinary school issues and, especially, the relationship between teachers and the authorities responsible for the administration and control of the work in schools. This paper aims to deep the knowledge on parish inspection and literary council, as components of the inspection that used to be present in the relations between teachers and inspectors. The methodology includes documental research, analysis of sources and crossing of information from reports and official letters with the provincial legislation of Paraná. We can conclude that, in spite of a relative legal organization when it comes to the distribution of administrative functions and control over public instruction, the latter remained quite precarious at the end of the provincial period, since only with the advance of social relations of production of material life the school would become necessary.

    2014-02-01

    For a secure and sustainable energy future, the United States (U.S.) must reduce its dependence on imported oil and reduce its emissions of carbon dioxide (CO{sub 2}) and other greenhouse gases (GHGs). To meet these strategic challenges, the U.S. wiU have to create fundamentally new technologies with performance levels far beyond what is now possible. Developing advanced post-combustion clean coal technologies for capturing CO{sub 2} from existing coal-fired power plants can play a major role in the country's transition to a sustainable energy future, especially when coupled with CO{sub 2}-enhanced oil recovery (CO{sub 2}-EOR). Pursuant to these goals, NRG Energy, Inc. (NRG) submitted an application and entered into a cost-shared collaboration with the U.S. Department of Energy (DOE) under Round 3 of the Clean Coal Power Initiative (CCPI) to advance low-emission coal technologies. The objective of the NRG W A Parish Post-Combustion CO{sub 2} Capture and Sequestration Demonstration Project is to establish the technical feasibility and economic viability of post-combustion CO{sub 2} capture using flue gas from an existing pulverized coal-fired boiler integrated with geologic sequestration via an enhanced oil recovery (EOR) process. To achieve these objectives, the project will be executed in three phases. Each phase represents a distinct aspect of the project execution. The project phases are: • Phase I. Project Definition/Front-End Engineering Design (FEED) • Phase ll. Detailed Engineering, Procurement & Construction • Phase III. Demonstration and Monitoring The purpose of Phase I is to develop the project in sufficient detail to facilitate the decision-making process in progressing to the next stage of project delivery. Phase n. This report provides a complete summary of the FEED study effort, including pertinent project background information, the scope of facilities covered, decisions, challenges, and considerations made regarding configuration and

  2. Predictors of the science achievement of eighth-grade students in the parish schools of the Archdiocese of Philadelphia

    Science.gov (United States)

    Shaw, Rosalie J. Papa

    National and international studies of science achievement point to a declining trend as students move from early elementary school through high school. Internationally, United States' science students are well above average in grade 4, slightly above average in grade 8, and well below average in grade 12. This study focused on eighth grade students and their seventh grade science teachers in the parish elementary schools of the Archdiocese of Philadelphia. Of particular interest was the possibility that a teacher who "feels confident" about his/her ability to teach science will teach it well, whether or not he/she has extensive formal science training. The research question was: Which of the selected variables, including the teachers' science-teaching self-efficacy beliefs, gender, age, years of teaching experience, years of science teaching experience, certification, highest degree earned, college major, and number of college science courses taken, class size, school size, school location, prior science achievement in the school, the students' general aptitude and overall achievement, as well as the economic status of their families, are predictors of student achievement in science at the eighth grade level? Initial correlational analyses revealed that eight of the eighteen variables were significantly correlated with science achievement. These variables were the schools' location and prior science achievement, students' overall achievement, general ability, and family income, and teachers' certification, overall science-teaching self-efficacy beliefs and personal science-teaching self-efficacy beliefs. Schools were then divided into the highest- and lowest-scoring groups based on TerraNova science subtest scores. Other variables based on TerraNova data were not analyzed further. The remaining five variables were analyzed using the appropriate t-tests to determine which, if any, were significantly different in the highest- and lowest-scoring groups. t-Tests showed

    The nature of this project is to equip and support research in nanoengineered systems for biomedical, bioenvironmental, and bioenergy applications. Funds provided by the Department of Energy (DoE) under this Congressional Directive were used to support two ongoing research projects at Louisiana Tech University in biomedical, bioenvironmental, and bioenergy applications. Two major projects (Enzyme Immobilization for Large Scale Reactors to Reduce Cellulosic Ethanol Costs, and Nanocatalysts for Coal and Biomass Conversion to Diesel Fuel) and to fund three to five additional seed projects were funded using the project budget. The project funds also allowed the purchase and repair of sophisticated research equipment that will support continued research in these areas for many years to come. Project funds also supported faculty, graduate students, and undergraduate students, contributing to the development of a technically sophisticated work force in the region and the State. Descriptions of the technical accomplishments for each funded project are provided. Biofuels are an important part of the solution for sustainable transportation fuel and energy production for the future. Unfortunately, the country's appetite for fuel cannot be satisfied with traditional sugar crops such as sugar cane or corn. Emerging technologies are allowing cellulosic biomass (wood, grass, stalks, etc.) to also be converted into ethanol. Cellulosic ethanol does not compete with food production and it has the potential to decrease greenhouse gas (GHG) emissions by 86% versus current fossil fuels (current techniques for corn ethanol only reduce greenhouse gases by 19%). Because of these advantages, the federal government has made cellulosic ethanol a high priority. The Energy Independence and Security Act of 2007 (EISA) requires a minimum production of at least 16 billion gallons of cellulosic ethanol by 2022. Indeed, the Obama administration has signaled an ambitious commitment of achieving

  10. Technical support for geopressured-geothermal well activities in Louisiana

    Energy Technology Data Exchange (ETDEWEB)

    1991-07-01

    Continuous recording microearthquake monitoring networks have been established around US Department of Energy (DOE) geopressured-geothermal design wells in southwestern Louisiana and southeastern Texas since summer 1980 to assess the effects well development may have had on subsidence and growth-fault activation. This monitoring has shown several unusual characteristics of Gulf Coast seismic activity. The observed activity is classified into two dominant types, one with identifiable body phases (type 1) and the other with only surface-wave signatures (type 2). During this reporting period no type 1 or body-wave events were reported. A total of 230 type 2 or surface-wave events were recorded. Origins of the type 2 events are still not positively understood; however, little or no evidence is available to connect them with geopressured-geothermal well activity. We continue to suspect sonic booms from military aircraft or some other human-induced source. 37 refs., 16 figs., 6 tabs.

    2014-01-01

    Elevation data are essential to a broad range of applications, including forest resources management, wildlife and habitat management, national security, recreation, and many others. For the State of Louisiana, elevation data are critical for flood risk management, natural resources conservation, agriculture and precision farming, infrastructure and construction management, water supply and quality, and other business uses. Today, high-density light detection and ranging (lidar) data are the primary sources for deriving elevation models and other datasets. Federal, State, Tribal, and local agencies work in partnership to (1) replace data that are older and of lower quality and (2) provide coverage where publicly accessible data do not exist. A joint goal of State and Federal partners is to acquire consistent, statewide coverage to support existing and emerging applications enabled by lidar data.

    Johnson-Thibaut, Penny M.; Demcheck, Dennis K.; Swarzenski, Christopher M.; Ensminger, Paul A.

    1998-01-01

    Approximately 170 Mgal/d (million gallons per day) of ground- and surface-water was withdrawn from the Barataria-Terrebonne Basins in 1995. Of this amount, surface water accounted for 64 percent ( 110 MgaVd) of the total withdrawal rates in the basins. The largest surface-water withdrawal rates were from Bayou Lafourche ( 40 Mgal/d), Bayou Boeuf ( 14 MgaVd), and the Gulf Intracoastal Waterway (4.2 Mgal/d). The largest ground-water withdrawal rates were from the Mississippi River alluvial aquifer (29 Mgal/d), the Gonzales-New Orleans aquifer (9.5 Mgal/d), and the Norco aquifer (3.6 MgaVd). The amounts of water withdrawn in the basins in 1995 differed by category of use. Public water suppliers within the basins withdrew 41 Mgal/d of water. The five largest public water suppliers in the basins withdrew 30 Mgal/d of surface water: Terrebonne Waterworks District 1 withdrew the largest amount, almost 15 MgaVd. Industrial facilities withdrew 88 Mgal/d, fossil-fuel plants withdrew 4.7 MgaVd, and commercial facilities withdrew 0.67 MgaVd. Aggregate water-withdrawal rates, compiled by parish for aquaculture (37 Mgal/d), livestock (0.56 Mgal/d), rural domestic (0.44 MgaVd), and irrigation uses (0.54 MgaVd), totaled about 38 MgaVd in the basins. Ninety-five percent of aquaculture withdrawal rates, primarily for crawfish and alligator farming, were from surface-water sources. >br> Total water-withdrawal rates increased 221 percent from 1960–95. Surface-water withdrawal rates have increased by 310 percent, and ground-water withdrawal rates have increased by 133 percent. The projection for the total water-withdrawal rates in 2020 is 220 MgaVd, an increase of 30 percent from 1995. Surface-water withdrawal rates would account for 59 percent of the total, or 130 Mgal/d. Surface-water withdrawal rates are projected to increase by 20 percent from 1995 to 2020. Analysis of water-quality data from the Mississippi River indicates that the main threats to surface water resources are

    2007-12-01

    The Virtual Museum, a Louisiana Board of Regents sponsored SELECT program, is a collaborative project between the Museum of Natural Science and the French Education Project at Louisiana State University. It offers Louisiana science teachers, in-training teachers, and immersion teachers a professional development program via six videoconferences. These videoconferences are broadcast from LSU to six distance-learning sites across the entire state of Louisiana. This unique teacher population was selected because in Louisiana, there are two types of K-8 science teachers: teachers in traditional classroom settings and teachers in immersion programs. In the Foreign language Immersion programs, the target language (French or Spanish) is the language of instruction and communication in the classroom. For each videoconference, teachers are provided content material that is prepared by geology faculty and graduate students, example of ongoing field research by LSU faculty members, classroom-ready activities, information on available loan material and on-line resources, training on the unique Scope-On-A-Rope microscope, pre-made PowerPoint presentations and virtual museum photos, all, in French and in English. Three of the videoconferences emphasize regional and statewide earth science topics including Louisiana fossils, rocks and minerals, and field techniques used to interpret Louisiana's geologic history. The activities provided for teachers are hands-on, inquiry based classroom exercises that focus on the availability of local materials. These activities can also be scaled for use in a variety of grade-levels and teachers are encouraged to use these activities in their classrooms. The program has proven to foster new collaboration between science teachers in regular programs and immersion schools while boosting the interest statewide for natural science topics.

  6. Implications of accelerated sea-level rise on Louisiana coastal environments

    Science.gov (United States)

    Ramsey, Karen E.; Penland, Shea; Roberts, Harry H.

    1991-01-01

    Natural and human-induced processes have combined to produce high rates of relative sea-level rise and coastal land loss in Louisiana. This paper presents historical trends in sea-level rise and the implication of predicted accelerated rise scenarios on Louisiana's coastal environments. Mean eustatic sea-level in the Gulf of Mexico is 0.23 cm/yr. In Louisiana, relative sea-level rise, which combines eustacy and subsidence, averages from 0.50 cm/yr in the chenier plain to 1.0 cm/yr in the delta plain. Subsidence due to the compaction of Holocene sediments is believed to be the major component influencing these high rates of rise. Subsidence contributes up to 80% of the observed relative sea-level rise in coastal Louisiana. The Environmental Protection Agency (EPA) predicts the rate of sea-level rise to increase over the next century due to global climate change. If these predictions are accurate, a dramatic increase in the coastal land loss conditions in Louisiana can be expected.

    Cadmium has been hypothesized to be a pancreatic carcinogen. We test the hypothesis that cadmium exposure is a risk factor for pancreatic cancer with a population-based case-control study sampled from a population with persistently high rates of pancreatic cancer (south Louisiana). We tested potential dietary and nondietary sources of cadmium for their association with urinary cadmium concentrations which reflect long-term exposure to cadmium due to the accumulation of cadmium in the kidney cortex. Increasing urinary cadmium concentrations were significantly associated with an increasing risk of pancreatic cancer (2nd quartile OR = 3.34, 3rd = 5.58, 4th = 7.70; test for trend P ≤ 0.0001). Potential sources of cadmium exposure, as documented in the scientific literature, found to be statistically significantly associated with increased risk of pancreatic cancer included working as a plumber, pipefitter or welder (OR = 5.88) and high consumption levels of red meat (4th quartile OR = 6.18) and grains (4th quartile OR = 3.38). Current cigarette smoking, at least 80 pack years of smoking, occupational exposure to cadmium and paints, working in a shipyard, and high consumption of grains were found to be statistically significantly associated with increased concentrations of urinary cadmium. This study provides epidemiologic evidence that cadmium is a potential human pancreatic carcinogen. PMID:23319964

    1981-01-01

    Dye-tracer studies were made in November 1978 and in June 1979 to define streamflow patterns in the Vermilion River. For the November 1978 study the tracer was injected at two locations, Surrey Street in Lafayette and about 7 miles downstream at State Highway 3073; the discharge at Surrey Street at the time of injection was 218 cubic feet per second. The two dye clouds merged at Broussard Cemetery, about 12.2 miles downstream from Surrey Street, after an elapsed time of about 270 hours. After 438 hours the dye cloud extended form the Abbeville bridge (Louisiana Highway 14 Bypass) upstream about 14.5 miles. In June 1979, a tracer was injected into the river at Surrey Street at Lafayette; the discharge at Surrey Street at the time of injection was 161 cubic feet per second. Forty-two hours after injection the leading edge of the tracer was located at the Milton pumping plant, 14 miles downstream from the injection site. The average pumping rate of the plant during the study was 440 cubic feet per second. Ninety hours after injection, no indication of the tracer was found in the river, but the tracer was found in a rice-irrigation cannal at State Highway 14, about 10 miles west of Abbeville. (USGS)

    1995-06-23

    Data were collected prior to termination of discharge at three sites (including two open bay sites at Delacroix Island and Bay De Chene) for the risk assessments. The Delacroix Island Oil and Gas Field has been in production since the first well drilling in 1940; the Bay De Chene Field, since 1942. Concentrations of 226Ra, 228Ra, 210Po, and 228Th were measured in discharges. Radium conc. were measured in fish and shellfish tissues. Sediment PAH and metal conc. were also available. Benthos sampling was conducted. A survey of fishermen was conducted. The tiered risk assessment showed that human health risks from radium in produced water appear to be small; ecological risk from radium and other radionuclides in produced water also appear small. Many of the chemical contaminants discharged to open Louisiana bays appear to present little human health or ecological risk. A conservative screening analysis suggested potential risks to human health from Hg and Pb and a potential risk to ecological receptors from total effluent, Sb, Cd, Cu, Pb, Ni, Ag, Zn, and phenol in the water column and PAHs in sediment; quantitiative risk assessments are being done for these contaminants.

  11. Daily movements of female mallards wintering in Southwestern Louisiana

    2011-01-01

    Understanding daily movements of waterfowl is crucial to management of winter habitats, especially along the Gulf Coast where hunting pressure is high. Radio-telemetry was used to investigate movements of female Mallards (Anas platyrchychos) wintering in southwestern Louisiana. Movement distances were analyzed from 2,455 paired locations (diurnal and nocturnal) of 126 Mallards during winters 2004-2005 and 2005-2006 to assess effects of winter, female age, areas closed (Lacassine National Wildlife Refuge [LAC], Cameron Prairie National Wildlife Refuge [CAM], Amoco Pool [AMOCO] or open to hunting [OPEN]), and habitat type, including all interactions. Movement distances from the various land management categories were not consistent by age, date, or by winter. Flight distances from LAC increased with date, whereas those from CAM and OPEN did not vary significantly by date. Female Mallards moved short distances between diurnal and nocturnal sites (ranging from 3.1 to 15.0 km by land management category), suggesting that they are able to meet their daily energy requirements within a smaller area than Northern Pintails (Anas acuta, hereafter Pintails), and thus minimize transit energy costs.

  12. Seafloor erosional processes offshore of the Chandeleur Islands, Louisiana

    Science.gov (United States)

    Twichell, David C.; Brock, John C.

    2011-01-01

    The Chandeleur Islands are a chain of barrier islands that lies along the eastern side of the modern Mississippi River Delta plain. The island chain is located near the seaward edge of the relict St. Bernard Delta, the part of the Mississippi Delta that formed between approximately 4,000 and 2,000 years before present and was later abandoned as sedimentation shifted southward. After abandonment of the St. Bernard Delta, deposits were reworked, and the sandy component was shaped into the Chandeleur Islands. With continued subsidence, the islands became separated from their original delta headland sources and presently are isolated from the mainland by the shallow Chandeleur Sound. Newly acquired geophysical data and vibracores provide an opportunity to better understand the processes that are shaping seafloor morphology (i.e., shape, geometry, and structure of the seafloor) on the inner shelf adjacent to the Chandeleur Islands. The inner shelf offshore of the Chandeleur Islands was mapped in 2006 and 2007 using swath bathymetry, sidescan sonar, and high-resolution seismic-reflection techniques. The detailed results of this study were published in December 2009 (Twichell and others, 2009) as part of a special issue of Geo-Marine Letters that documents early results from the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazard Susceptibility Project. This study addresses questions and concerns related to limited sand resources along the Louisiana shelf and their implications to long-term relative sea-level rise and storm impacts.

  14. Challenges of ecosystem restoration in Louisiana - availability of sediment and its management

    Science.gov (United States)

    Khalil, S. M.; Freeman, A. M.

    2015-03-01

    Human intervention has impaired the Mississippi River's ability to deliver sediment to its delta wetlands, and as a consequence acute land loss in coastal Louisiana has resulted in an unprecedented ecocatastrophe. To mitigate this degradation, an unparalleled restoration effort is underway. For this effort to be successful and sustainable, various sediment input mechanisms must be integrated, including: building appropriate sediment-diversions; beneficially using the millions of cubic metres of sediment dredged annually from navigational channels; harvesting deposits of sand and suitable sediment from the river and offshore; and related sediment management activities that are compatible with other uses of the river. A comprehensive sediment management plan has been developed to identify and delineate potential sediment sources for restoration, and to provide a framework for managing sediment resources wisely, cost effectively, and in a systematic manner. The Louisiana Sediment Management Plan provides regional strategies for improved comprehensive management of Louisiana's limited sediment resources.

  15. National Uranium Resource Evaluation: Palestine Quadrangle, Texas and Louisiana

    International Nuclear Information System (INIS)

    The uranium resource potential of the Palestine Quadrangle, Texas and Louisiana, was evaluated to a depth of 1500 m (5000 ft) using criteria established for the National Uranium Resource Evaluation program. Data derived from geochemical analyses of surface samples (substrate, soil, and stream sediment) in conjunction with hydrochemical data from water wells were used to evaluate geologic environments as being favorable or unfavorable for the occurrence of uranium deposits. Two favorable environments have been identified in the Palestine Quadrangle: potential deposits of modified Texas roll-type in fluvial channels and associated facies within the Yegua Formation, and potential occurrences along mineralization fronts associated with the Elkhart Graben and Mount Enterprise fault system. Unfavorable environments include: Cretaceous shales and limestones, Tertiary fine-grained marine sequences, Tertiary sandstone units that exhibit favorable host-rock characteristics but fail to show significant syngenetic or epigenetic mineralization, and Quaternary sands and gravels. Unevaluated units include the Woodbine Group (Upper Cretaceous), Jackson Group (Tertiary), and Catahoula Formation (Tertiary). The subsurface interval of the Jackson Group and Catahoula Formation contains depositional facies that may represent favorable environments; however, the evaluation of these units is inconclusive because of the general lack of shallow subsurface control and core material. The Woodbine Group, restricted to the subsurface except for a small exposure over Palestine Dome, occurs above 1500 m (5000 ft) in the northwest quarter of the quadrangle. The unit exhibits favorable host-rock characteristics, but the paucity of gamma logs and cores, as well as the lack of hydrogeochemical and stream-sediment reconnaissance data, makes evaluation of the unit difficult

  16. THE SOCIAL NETWORK OF THE ORTHODOX PARISH COMMUNITY: POSSIBILITIES FOR APPLYING THE ANALYSIS OF SOCIAL NETWORKS TO THE SOCIOLOGY OF RELIGION

    Directory of Open Access Journals (Sweden)

    Elena Prutskova

    2013-08-01

    Full Text Available This article examines the understanding of the social network and lays the foundation for the possibility of applying the social network approach to the sociology of religion. During the last twenty years, Russian sociological circles have been actively discussing the question of whether Orthodoxy exerts any influence on contemporary Russia. Until the present, the amount of influence has been calculated by examining how people identify themselves and by how frequently they practice their religion. With the help of an apparatus of network analysis, an attempt is made in this article to detect still another way religion influences Russian today. The authors suggest a threepart typology of the way a contemporary person relates to religion: conversion, linkage through a social network, linkage through publicly visible marks of religiosity. With the aid of the foregoing, one can hazard the hypothesis that the second factor is of prime importance especially in countries threatened by forced secularization. The authors question the social mechanics gearing the functioning of contemporary Russian society and attempt to calculate the potential outreach of the contemporary Russian Orthodox parish. Data collected by the authors allow one to suppose that the influence of linking oneself to religion through and amid the various facets of life of the average Russian may be just as effective as the conversion experience

  17. A Comparison of the Primary and Secondary Wood Products Sectors in Louisiana

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available As part of an ongoing research program, the Louisiana forest products industry is surveyed every five years to identify salient issues, challenges, and opportunities. In this paper, we compare the results from two studies conducted on the primary and secondary sectors in Louisiana. In the past, we produced two papers based on research results, one for the primary and one for the secondary sector. However, this paper compares the answers to questions asked in both surveys. Louisiana’s forests represent an important resource for the state, both in terms of income to landowners and as inputs to the forest products industry. Both primary and secondary respondents indicate an interest in increasing their workforce in the next five years. The issues that drive the company expansion fall into four areas: the overall attractiveness of the business climate of the community and state, labor productivity, costs and supply, and financing. The results of this study can be used by Louisiana industry members in the primary and secondary sectors to identify common challenges, opportunities and issues that promote or hinder sector development. Policymakers can work more effi ciently with industry members where commonalities exist. Understanding the markets, plant location decisions, raw material availability, workforce training needs, and other issues can be a source of competitive advantage for Louisiana manufacturers.

  10. Environmental requirements for Louisiana Tech University with an emphasis on an asbestos management plan

    International Nuclear Information System (INIS)

    The intent of this paper is to provide both an overview of the environmental regulations affecting Louisiana Tech University and to discuss possible compliance solutions. A major area of emphasis will be the Asbestos Management Plan that Louisiana Tech is presently beginning to implement. The tremendous expansion of environmental laws during the last twenty years has significant implications for colleges and universities. No longer are laws applicable only to industry; educational institutions must comply with the same requirements. If they do not they will face potential legal liabilities. Because of substantial penalties government agencies can impose for environmental violations, and the substantial damages that private parties can seek for environmental injuries, it is critical that institutions be aware of, understand, and follow environmental requirements. Louisiana Tech University's compliance requirements will be studied. A special emphasis will be put on the Asbestos Management program now being implemented on campus. The information is divided into two main parts. Part One will describe the major federal and state regulations that directly affect daily operations at Louisiana Tech University. Current and future needs in all environmental areas will be discussed briefly. Part Two focuses on the Asbestos Management program and covers all aspects of implementation of a viable asbestos program. Each part has been divided into chapters for ease of information retrieval

    2015-11-01

    Full Text Available Louisiana iris is tolerant to and accumulates the heavy metal lead (Pb. However, there is limited knowledge of the molecular mechanisms behind this feature. We describe the transcriptome of Louisiana iris using Illumina sequencing technology. The root transcriptome of Louisiana iris under control and Pb-stress conditions was sequenced. Overall, 525,498 transcripts representing 313,958 unigenes were assembled using the clean raw reads. Among them, 43,015 unigenes were annotated and their functions classified using the euKaryotic Orthologous Groups (KOG database. They were divided into 25 molecular families. In the Gene Ontology (GO database, 50,174 unigenes were categorized into three GO trees (molecular function, cellular component and biological process. After analysis of differentially expressed genes, some Pb-stress-related genes were selected, including biosynthesis genes of chelating compounds, metal transporters, transcription factors and antioxidant-related genes. This study not only lays a foundation for further studies on differential genes under Pb stress, but also facilitates the molecular breeding of Louisiana iris.

  16. Man in Louisiana's coastal zone - From reclamation to subsidence

    Energy Technology Data Exchange (ETDEWEB)

    Davis, D.W. (Louisiana Geological Survey, Baton Rouge (USA))

    1990-09-01

    For more than 300 years the US marsh lands were thought to be of no economic value. They were considered useless wastelands. Today, they are recognized as valuable and highly productive environments. As a renewable resource that operates with minimum capital expenditures, the wetlands are epitomized in Louisiana. Even so, south Louisiana's first settlers were unaware of the wetlands value. These coastal lowlands were considered a nuisance. They bred yellow fever-carrying mosquitos and contributed directly and indirectly to flooding. Consequently, to overcome the hardships of being sea-level citizens, for more than 250 years the inhabitants have systematically reclaimed the marshes and swamps. As a result of the intense utilization of levees and pumps, normally wet property began to dry out, losing some of its natural buoyancy, increasing regional subsidence. Man-induced negative land surfaces are producing an urbanized population that must face the realities of subsidence caused by unregulated reclamation. New Orleans has, in fact, become North America's premier sinking city. The population has been forced to learn how to live with the problem. Nevertheless, these people are at risk, particularly if the current predicted sea-level rise of 1.2 mm/yr is correct. In the main, Louisiana's coastal issues will become those of the nation and represent the precursor of things to come. Louisiana's reaction and solutions to these issues will establish a precedent for the remainder of the country to follow.

  20. The Impact of Rainfall on Fecal Coliform Bacteria in Bayou Dorcheat (North Louisiana

    Directory of Open Access Journals (Sweden)

    Paul B. Tchounwou

    2006-03-01

    Full Text Available Fecal coliform bacteria are the most common pollutant in rivers and streams. In Louisiana, it has been reported that 37% of surveyed river miles, 31% of lakes, and 23% of estuarine water had some level of contamination. The objective of this research was to assess the effect of surface runoff amounts and rainfall amount parameters on fecal coliform bacterial densities in Bayou Dorcheat in Louisiana. Bayou Dorcheat has been designated by the Louisiana Department of Environmental Quality as a waterway that has uses such as primary contact recreation, secondary contact recreation, propagation of fish and wildlife, agriculture and as being an outstanding natural resource water. Samples from Bayou Dorcheat were collected monthly and analyzed for the presence of fecal coliforms. Fecal coliforms isolated from these samples were identified to the species level. The analysis of the bacterial levels was performed following standard test protocols as described in Standard Methods for the Examination of Water and Wastewater. Information regarding the rainfall amounts and surface runoff amounts for the selected years was retrieved from the Louisiana Office of State Climatology. It was found that a significant increase in the fecal coliform numbers may be associated with average rainfall amounts. Possible sources of elevated coliform counts could include sewage discharges from municipal treatment plants and septic tanks, storm water overflows, and runoff from pastures and range lands. It can be concluded that nonpoint source pollution that is carried by surface runoff has a significant effect on bacterial levels in water resources.

  4. Potentiometric-level monitoring program: Mississippi and Louisiana. Annual status report for fiscal year 1984

    International Nuclear Information System (INIS)

    Potentiometric-level data presented in this report were collected from October 1983 through September 1984 at 79 wells in Mississippi and Louisiana. These wells are located near Richton and Cypress Creek Domes in Mississippi and Vacherie Dome in Louisiana. Fourteen wells were added to the program during this period. Two of these wells were not measurable. Two wells previously unmeasurable were located and measured. One well was destroyed during military maneuvers in the area. Analysis of the data indicated minimal, if any, change in potentiometric levels during the past year in the Citronelle, Hattiesburg, Cockfield, Sparta, and Wilcox Formations in Mississippi. A continuing decline in potentiometric levels, ranging from 0.3 to 0.6 foot per year, occurred in the wells screened in the caprock at Richton and Cypress Creek Domes. The Catahoula Formation experienced a continuing decline in potentiometric levels of about 2 feet per year. Two wells in the Cook Mountain Formation showed a continuing rise in potentiometric levels ranging from 8 to 30 ft during the past fiscal year. Wells screened in the Austin Formation in Louisiana showed a fall in potentiometric levels of 2 to 3 ft over the past fiscal year. Other formations in Louisiana generally showed no change in potentiometric levels over the past year. 26 refs., 2 figs., 3 tabs

    2012-01-01

    This project provides highly detailed and accurate datasets of a portion of Alligator Point, Louisiana, acquired on March 5 and 6, 2010. The datasets are made available for use as a management tool to research scientists and natural-resource managers. An innovative airborne lidar instrument originally developed at the National Aeronautics and Space Administration (NASA) Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL), was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multispectral color-infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for sub-meter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine aircraft, but the instrument was deployed on a Pilatus PC-6. A single pilot, a lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL system, and the resulting data were then processed using the Airborne Lidar Processing System (ALPS), a custom-built processing system developed in a NASA-USGS collaboration. ALPS supports the exploration and processing of lidar data in an interactive or batch mode. Modules for presurvey flight-line definition, flight-path plotting, lidar raster and waveform investigation, and digital camera image playback have been developed. Processing algorithms have

  8. Integrating Climate Science, Ecosystem Modeling, and Resource Management to Develop a Coastal Master Plan for Louisiana

    Science.gov (United States)

    Groves, D.; Sharon, C.; Knopman, D.

    2012-12-01

    The Coastal Protection and Restoration Authority of Louisiana (CPRA) asked the RAND Corporation to develop a new Planning Tool to support Louisiana's 2012 Coastal Master Plan. The Planning Tool integrates climate science, ecosystem modeling, and resource management planning to comparing different risk reduction and coastal restoration projects and for developing groups of projects, or alternatives, for consideration for the Master Plan. The Planning Tool presents its results in an interactive visualization environment to support deliberation by CPRA decisionmakers and stakeholders. The Planning Tool uses new standardized estimates of project costs, planning and construction duration, and other project attributes along with science-based model estimates of project effects on risk reduction, land building, and ecosystem services. The Planning Tool considers how outcomes would differ under different future scenarios reflecting climate change, demographics, and other uncertainties. The Planning Tool uses a constrained optimization algorithm to develop a range of alternatives that meet CPRA's desired outcomes with respect to future flood risk reduction, coast-wide land area, and other decision criteria. Beginning in 2011, CPRA used the Planning Tool to compare hundreds of possible hurricane flood risk reduction and coastal restoration projects under several scenarios of long-term future conditions. CPRA next used the Planning Tool to develop and analyze hundreds of different alternatives that together would best meet Louisiana's goals of reducing hurricane flood risk and achieving a sustainable landscape. The Planning Tool then enabled CPRA to specify planning parameters such as total available funding, funding splits between risk reduction and restoration projects, and minimum levels of projected achievement of goals for ecosystem service and risk reduction decision criteria. Using this information, the Planning Tool then identified how those alternatives could be

    little or no treatment for most uses. The water is a soft, sodium bicarbonate type and therefore has a low to moderate dissolved-solids content. Mineral content increases generally downdip in an aquifer. Excessive iron, common in shallow aquifers, is objectionable for some water uses. Water from the streams, except in salty tidal reaches, is less mineralized than ground water; in 10 sites the median dissolved-solids content in streamflow was 50 milligrams per liter or less. Moderately intensive ground-water development has been made in the Bogalusa area, Louisiana; at the Mississippi Test Facility, Hancock County, Miss. ; and in the Jackson area, Mississippi. Wells with pumping rates of 500 to 1,000 gallons per minute each are common throughout the Pearl River basin, and some deep wells flow more than 3,000 gallons per minute in the coastal lowland areas. Probably 20 million gallons per day of artesian water flows uncontrolled from wells in the southern part of the basin. Ground-water levels, except in the higher altitudes, are within 60 feet of the surface, and flowing wells are common in the valleys and in the coastal Pine Meadows. Decline of water level is a problem in only a few small areas. Saline water as a resource is available for development from aquifers and streams near the coast and from aquifers at considerable depth in most of the Pearl River basin. Pollution is a problem in oil fields and in reaches of some streams below sewage and other waste-disposal points. The basin estuary contains water of variable quality but has potential for certain water-use developments that will require special planning and management.

Efforts to limit breeding of the dengue vector Aedes aegypti are often hampered by lack of community awareness of the disease.Methods: Sixty-eight households in St Catherine Parish, Jamaica completed a pilot knowledge, attitude, and practice questionnaire as part of a routine container survey for presence of A. aegypti larvae.Results: Infestation levels were high according to traditional Stegomyia indices (Breteau index = 325; however, general knowledge of dengue symptoms, A. aegypti breeding sites, and preventive practices was low. After examining the links between demographic characteristics, dengue knowledge, and the number of breeding sites per house, higher educational achievement was associated with higher dengue knowledge, but also with more unprotected containers. Overall dengue knowledge was not associated with household container counts. Spatial statistics identified weak clustering of larvae-positive containers, and larvae were concentrated in three key container types.Conclusion: Residents may only understand the role of certain container types, and significant gaps in general knowledge of the disease may inhibit vector control. This pilot demonstrates the feasibility of conducting inexpensive, rapid assessment of community knowledge and breeding levels for local governments lacking the resources for a more methodologically robust vector assessment

  11. Recoverable Resource Estimate of Identified Onshore Geopressured Geothermal Energy in Texas and Louisiana (Presentation)

    2012-04-01

    Geopressured geothermal reservoirs are characterized by high temperatures and high pressures with correspondingly large quantities of dissolved methane. Due to these characteristics, the reservoirs provide two sources of energy: chemical energy from the recovered methane, and thermal energy from the recovered fluid at temperatures high enough to operate a binary power plant for electricity production. Formations with the greatest potential for recoverable energy are located in the gulf coastal region of Texas and Louisiana where significantly overpressured and hot formations are abundant. This study estimates the total recoverable onshore geopressured geothermal resource for identified sites in Texas and Louisiana. In this study a geopressured geothermal resource is defined as a brine reservoir with fluid temperature greater than 212 degrees F and a pressure gradient greater than 0.7 psi/ft.

    2011-01-01

    The Coastwide Reference Monitoring System (CRMS) program was established to assess the effectiveness of individual coastal restoration projects and the cumulative effects of multiple projects at regional and coastwide scales. In order to make these assessments, analytical teams have been assembled for each of the primary data types sampled under the CRMS program, including vegetation, hydrology, landscape, and soils. These teams consist of scientists and support staff from the U.S. Geological Survey and other Federal agencies, the Louisiana Office of Coastal Protection and Restoration, and university academics. Each team is responsible for developing or identifying parameters, indices, or tools that can be used to assess coastal wetlands at various scales. The CRMS Vegetation Analytical Team has developed a Floristic Quality Index for coastal Louisiana to determine the quality of a wetland based on its plant species composition and abundance.

    Disasters and displacement increasingly affect and challenge urban settings. How do pregnant women fare in the aftermath of a major disaster? This paper investigates the effect of pregnancies in disaster situations. The study tests a hypothesis that pregnant women residing in hurricane-prone areas suffer higher health risks. The setting is Louisiana in the Gulf Coast, United States, a state that continually experiences hurricane impacts. The time period for the analysis is three years following the landfall of Hurricane Andrew in 1992. We analysed low birth weight and preterm deliveries before and after landfall, as a whole and by race. Findings support an association between hazards and health of a community and indicate that pregnant women in the affected area, irrespective of race, are more likely to experience preterm deliveries compared to pre-event births. Results suggest there is a negative health legacy impact in Louisiana as a result of hurricane landfall.

  18. Export of Dissolved Lignin from Coastal Wetlands to the Louisiana Shelf

    2008-12-01

    Here we report on spatial and temporal changes in the concentration and composition of dissolved lignin- phenols in surface and bottom waters off the Louisiana coast (USA). Samples were collected at 7 stations on 2 cruises (April, and July, 2008) along a transect that spanned from inside Terrebonne Bay, Louisiana (12 m water depth) to the outer-most station on the inner Louisiana shelf (21 m water depth). The highest average concentration of dissolved organic carbon (DOC) and dissolved lignin, during both cruises, occurred at the interface between Terrebonne Bay and the inner shelf. Average DOC and dissolved lignin concentrations were significantly higher in April than in July across most stations. Based on hydrologic data, these higher concentrations clearly reflect a combined mixing of DOM from plume waters to the west and local marsh inputs. The cinnamyl/vanillyl (C/V) and syringyl/vanillyl (S/V) ratios indicated that the predominant source of lignin was from non-woody angiosperms - likely the dominant species of wetland plants Spartina alterniflora and S. patens (Spartina spp.) that border the entire bay. The high vanillic acid to vanillin (Ad/Al)v ratios for all stations were typical of that found near estuarine boundaries, where biologically- and photochemically-mediated lignin decay processes are important. This preliminary data indicates that wetlands provide another source of dissolved organic matter (DOM) to the Louisiana shelf that likely contributes to microbial food resources and hence hypoxia, especially in the context of the instability and extensive erosion of these marshes over the past ca. 50 years. This has important implications for the current management plan to reduce hypoxia in the GOM, particularly in those regions that extend west of the nutrient-rich highly productive near-field zones of Atchafalaya-Mississippi river plumes.

    This study aimed to assess the degree of potential temperature and precipitation change as predicted by the HadCM3 (Hadley Centre Coupled Model, version 3) climate model for Louisiana, and to investigate the effects of potential climate change on surface soil organic carbon (SOC) across Louisiana using the Rothamsted Carbon Model (RothC) and GIS techniques at the watershed scale. Climate data sets at a grid cell of 0.5° × 0.5° for the entire state of Louisiana were collected from the HadCM3 model output for three climate change scenarios: B2, A2, and A1F1, that represent low, higher, and even higher greenhouse gas emissions, respectively. Geo-referenced datasets including USDA-NRCS Soil Geographic Database (STATSGO), USGS Land Cover Dataset (NLCD), and the Louisiana watershed boundary data were gathered for SOC calculation at the watershed scale. A soil carbon turnover model, RothC, was used to simulate monthly changes in SOC from 2001 to 2100 under the projected temperature and precipitation changes. The simulated SOC changes in 253 watersheds from three time periods, 2001-2010, 2041-2050, and 2091-2100, were tested for the influence of the land covers and emissions scenarios using SAS PROC GLIMMIX and PDMIX800 macro to separate Tukey-Kramer (p change from 30.7 t/ha in 2001 to 25.4, 26.6, and 27.0 t/ha in 2100, respectively. Annual SOC changes will be significantly different among the land cover classes including evergreen forest, mixed forest, deciduous forest, small grains, row crops, and pasture/hay (p < 0.0001), emissions scenarios (p < 0.0001), and their interactions (p < 0.0001).

    During August 24th through 27th in 1992, Hurricane Andrew passed through the Gulf Of Mexico almost directly over several moorings on the easternmost Louisiana shelf portion of the Texas-Louisiana Shelf (LATEX) coastal ocean monitoring program. Examination of the current meter time-series showed the existence of fast moving, long shelf waves over the entire Texas-Louisiana shelf west of the storm passage for up to 12 days after direct forcing ceased. The LATEX program featured 31 moorings each with 3 current meters over the 10, 20, 50, and 200 meter isobaths in 5 cross sectional lines with additional coverage on the 200 meter isobath from the Louisiana-Mississippi River delta, to Corpus Christi, Texas. Additionally, several pressure records from LATEX and several NOAA historical coastal tide gauge data from Sabine Pass to Port Isabella, Texas were incorporated. Raw, 3-hour low pass filtered, and 40-hour low pass filtered versions of the current data were analyzed. The pressure data used were detided using a least squares fit, and the tidal records were detided using the NOAA predicted tides for that location. All data were analyzed using a wavelet analysis to determine the spectra over time. The analyzed data shows that the shelf response was largely dominated in the internal Kelvin wave mode. The wave propagated towards the west on the shelf at approximately 400 km/day. These results are contrasted and compared with wave modes predicted for coastal trapped wave solutions. The output of a coastal ocean model simulation using a forced wind field similar to the storm are also contrasted and compared with the observed data.

  4. Numerical analysis of the primary processes controlling oxygen dynamics on the Louisiana Shelf

    2014-10-01

    Full Text Available The Louisiana shelf in the northern Gulf of Mexico receives large amounts of freshwater and nutrients from the Mississippi/Atchafalaya River system. These river inputs contribute to widespread bottom-water hypoxia every summer. In this study, we use a physical-biogeochemical model that explicitly simulates oxygen sources and sinks on the Louisiana shelf to identify the key mechanisms controlling hypoxia development. First, we validate the model simulation against observed dissolved oxygen concentrations, primary production, water column respiration, and sediment oxygen consumption. In the model simulation, heterotrophy is prevalent in shelf waters throughout the year except near the mouths of the Mississippi and Atchafalaya Rivers where primary production exceeds respiratory oxygen consumption during June and July. During this time, efflux of oxygen to the atmosphere, driven by photosynthesis and surface warming, becomes a significant oxygen sink while the well-developed pycnocline isolates autotrophic surface waters from the heterotrophic and hypoxic waters below. A substantial fraction of primary production occurs below the pycnocline in summer. We investigate whether this primary production below the pycnocline is mitigating the development of hypoxic conditions with the help of a sensitivity experiment where we disable biological processes in the water column (i.e. primary production and water column respiration. In this experiment below-pycnocline primary production reduces the spatial extent of hypoxic bottom waters only slightly. Our results suggest that the combination of physical processes and sediment oxygen consumption largely determine the spatial extent and dynamics of hypoxia on the Louisiana shelf.

    The coastal wetlands of Louisiana are a unique ecosystem that supports a diversity of wildlife as well as a diverse community of commercial interests of both local and national importance. The state of Louisiana has established a 5-year cycle of scientific investigation to provide up-to-date information to guide future legislation and regulation aimed at preserving this critical ecosystem. Here we report on a model that projects changes in plant community distribution and composition in response to environmental conditions. This model is linked to a suite of other models and requires input from those that simulate the hydrology and morphology of coastal Louisiana. Collectively, these models are used to assess how alternative management plans may affect the wetland ecosystem through explicit spatial modeling of the physical and biological processes affected by proposed modifications to the ecosystem. We have also taken the opportunity to advance the state-of-the-art in wetland plant community modeling by using a model that is more species-based in its description of plant communities instead of one based on aggregated community types such as brackish marsh and saline marsh. The resulting model provides an increased level of ecological detail about how wetland communities are expected to respond. In addition, the output from this model provides critical inputs for estimating the effects of management on higher trophic level species though a more complete description of the shifts in habitat.

  6. The Role of Blacks in Establishing Cattle Ranching in Louisiana in the Eighteenth Century .

    2012-01-01

    A longstanding assumption posits that white ranchers from the French Caribbean colony of Saint-Domingue, now Haiti, provided the knowledge to establish the first cattle ranches in Louisiana in the mid-eighteenth century, that blacks merely provided the labor, and that the herding ecology involved was the same as that of the Acadian ranchers who followed. Reconstruction of the locations of the first major ranches and the backgrounds of their owners and slaves, however, reveals that none of them came to Louisiana from Saint-Domingue and that the ranches occupied the western margin of the Atchafalaya basin, an environment quite different than the prairies of southwestern Louisiana later inhabited by Acadian ranchers. While the sources cannot yield a complete account of the process through which cattle ranching became established, they do suggest that none of the white ranchers brought relevant experience from the Caribbean or France, that some of the blacks might have brought such experience from Africa, and that people of African, European, native, and mixed origins all contributed knowledge and creativity, as well as labor, in founding a distinctive herding ecology that differed substantially from that of the subsequent Acadian ranches PMID:27652419

    Full Text Available The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents’ addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes and individual (network distance to the closest alcohol outlet estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent’s home was more strongly associated with alcohol consumption than outlet density in the respondent’s census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

  8. The effect of a Louisiana crude oil discharge from a pipeline break on the vegetation of a southeast Louisiana brackish marsh

    A pipeline break on 23 April 1985 near Nairn, Louisiana, resulted in the release of approximately 300 barrels of Louisiana crude oil into a brackish marsh dominated by a vegetative mixture of Spartina patens, S. alterniflora and Distichlis spicata. Since the impact of oil spills on brackish marshes has received little attention, we initiated this investigation to assess the post-spill status of the vegetation. Sixty-eight randomly selected plots located on 15 transects which traverse the complete study area were sampled for various vegetative cover parameters. The major impact of the spill was confined to the 50-acre (20-ha) marsh located immediately around the pipeline rupture. The oil caused a 64% reduction in live vegetative cover (adjusted for differences in total percentage cover among plots) in this marsh 3 months after the spill. This high plant mortality from a relatively low oil dosage (estimated at 0.28 liters/m{sup 2}) was probably due to the contact of the oil with a large percentage (about 30-70%) of the photosynthetic leaf surfaces of the vegetation and the penetration of the oil into the marsh substrate.

    The Barrier Island Comprehensive Monitoring (BICM) program was implemented under the Louisiana Coastal Area Science and Technology (LCA S&T) office as a component of the System Wide Assessment and Monitoring (SWAMP) program. The BICM project was developed by the State of Louisiana (Coastal Protection Restoration Authority [CPRA], formerly Department of Natural Resources [DNR]) to complement other Louisiana coastal monitoring programs such as the Coastwide Reference Monitoring System-Wetlands (CRMS-Wetlands) and was a collaborative research effort by CPRA, University of New Orleans (UNO), and the U.S. Geological Survey (USGS). The goal of the BICM program was to provide long-term data on the barrier islands of Louisiana that could be used to plan, design, evaluate, and maintain current and future barrier-island restoration projects. The BICM program used both historical and newly acquired (2006 to 2010) data to assess and monitor changes in the aerial and subaqueous extent of islands, habitat types, sediment texture and geotechnical properties, environmental processes, and vegetation composition. BICM datasets included aerial still and video photography (multiple time series) for shoreline positions, habitat mapping, and land loss; light detection and ranging (lidar) surveys for topographic elevations; single-beam and swath bathymetry; and sediment grab samples. Products produced using BICM data and analyses included (but were not limited to) storm-impact assessments, rate of shoreline and bathymetric change, shoreline-erosion and accretion maps, high-resolution elevation maps, coastal-shoreline and barrier-island habitat-classification maps, and coastal surficial-sediment characterization maps. Discussions in this report summarize the extensive data-collection efforts and present brief interpretive analyses for four coastal Louisiana geographic regions. In addition, several coastal-wide and topical themes were selected that integrate the data and analyses within a

  10. Land Area Change in Coastal Louisiana: A Multidecadal Perspective (from 1956 to 2006)

    Science.gov (United States)

    2008-01-01

    The U.S. Geological Survey (USGS) analyzed changes in the configuration of land and water in coastal Louisiana by using a sequential series of 14 data sets summarizing land and water areas from 1956 to 2006. The purpose of this study is to provide a spatially and temporally consistent source of quantitative information on land area across coastal Louisiana, broken into three physiographic provinces (the term 'coastal Louisiana' is used to present data on the collective area). The land-water data sets used in this study are interpreted through spatial analysis and by linear regression analysis. The spatial depictions of land area change reveal a complex and interwoven mosaic of loss and gain patterns caused by natural and human-induced processes operating at varied temporal and spatial scales, resulting in fluctuating contributions to coastal loss. The linear regression analysis provides a robust estimate of recent change trends by comparing land area over time for all data sets from 1985 to 2004 and from 1985 to 2006 by physiographic province across coastal Louisiana. The 1956 to 2006 map showing multidecadal changes, along with the linear regressions of land area change presented in this study, provide a comprehensive and concise presentation of historical trends and rates of land area change in coastal Louisiana. Taking a broad historical view provides an in-depth understanding of land area changes over time. For example, one observation provided by our historical review is that the majority of the widespread, nontransitory land gains depicted on the map over the past 50 years, with the exception of the progradation of the Atchafafalaya River and Wax Lake deltas, are primarily related to sediment placement and landward migration of barrier islands. Another point revealed by our historical approach is that recent land losses caused by hurricanes sometimes commingled with or exacerbated older losses formed during the 1956 to 1978 period. Furthermore, our analyses

  14. Sugar cane/sweet sorghum as an ethanol feedstock in Louisiana and Piedmont

    International Nuclear Information System (INIS)

    Cost to provide readily fermentable feedstock for a year round sweet sorghum-to-ethanol production facility, up to the point at which fermentation begins, was determined. It was assumed that sweet sorghum is produced on marginal crop lands in the Southeastern Piedmont, and is purchased, standing in the field by a central ethanol production facility. Feedstock cost varied from $1.96 to $2.98/gal of ethanol potential depending on harvest system and use of by-products. Major contributors to feedstock cost were field production, harvest/field processing, and cost to evaporate juice to a storable syrup. Cost to transport feedstock to a central production facility, and cost of storage were relatively minor components of total cost, contributing only $0.05 and $0.06/gal ethanol potential, respectively. For a point of comparison, cost of producing ethanol feedstock from sugar cane, based on current processing practices in Louisiana sugar mills, was determined to be $2.50/gal ethanol potential. This cost is higher than determined for most options in the Piedmont for two reasons: (1) sugar cane demands a higher price in Louisiana than was assumed for sweet sorghum in the Piedmont, and (2) little market exists in Louisiana for by-products of sugar milling, consequently, no by-product credit was assigned. Current market value of ethanol must approximately double before a sweet sorghum-to-ethanol industry in the Piedmont could be economically viable, as no opportunity was identified for a significant reduction in feedstock cost

    Coastal Louisiana wetlands contain about 37% of the estuarine herbaceous marshes in the conterminous United States. The long-term stability of coastal wetlands is often a function of a wetland's ability to maintain elevation equilibrium with mean sea level through processes such as primary production and sediment accretion. However, Louisiana has sustained more coastal wetland loss than all other states in the continental United States combined due to a combination of natural and anthropogenic factors, including sea-level rise. This study investigates the potential impact of current and accelerating sea-level rise rates on key coastal wetland habitats in southeastern Louisiana using the Sea Level Affecting Marshes Model (SLAMM). Model calibration was conducted using a 1956–2007 observation period and hindcasting results predicted 35% versus observed 39% total marsh loss. Multiple sea-level-rise scenarios were then simulated for the period of 2007–2100. Results indicate a range of potential wetland losses by 2100, from an additional 2,188.97 km2 (218,897 ha, 9% of the 2007 wetland area) under the lowest sea-level-rise scenario (0.34 m), to a potential loss of 5,875.27 km2 (587,527 ha, 24% of the 2007 wetland area) in the highest sea-level-rise scenario (1.9 m). Model results suggest that one area of particular concern is the potential vulnerability of the region's baldcypress-water tupelo (Taxodium distichum-Nyssa aquatica) swamp habitat, much of which is projected to become permanently flooded (affecting regeneration) under all modeled scenarios for sea-level rise. These findings will aid in the development of ecosystem management plans that support the processes and conditions that result in sustainable coastal ecosystems.

Using a BACIP with data on successive shrimp year-classes of multiple basins, we found both species to become more abundant in basins that were affected by the spill, while mean shrimp size either not change after the spill, or increased in both affected and unaffected basins. We conclude that following the oil spill abundances of both species increased within affected estuaries, whereas mean size may have been unaffected. We propose two factors that may have caused these results: 1 exposure to polycyclic aromatic hydrocarbons (PAHs may have reduced the growth rate of shrimp, resulting in a delayed movement of shrimp to offshore habitats, and an increase of within-estuary shrimp abundance, and 2 fishing closures established immediately after the spill, may have resulted in decreased fishing effort and an increase in shrimp abundance. This study accentuates the complexities in determining ecological effects of oil spills, and the need of studies on the organismal level to reveal cause-and-effect relationships of such events.

    2012-01-01

    The Louisiana black bear (Ursus americanus luteolus) is comprised of 3 subpopulations, each being small, geographically isolated, and vulnerable to extinction. Hurricanes Katrina and Rita struck the Louisiana and Mississippi coasts in 2005, potentially altering habitat occupied by this federally threatened subspecies. We used data collected on radio-telemetered bears from 1993 to 1995 and pre-hurricane landscape data to develop a habitat model based on the Mahalanobis distance (D2) statistic. We then applied that model to post-hurricane landscape data where the telemetry data were collected (i.e., occupied study area) and where bear range expansion might occur (i.e., unoccupied study area) to quantify habitat loss or gain. The D2 model indicated that quality bear habitat was associated with areas of high mast-producing forest density, low water body density, and moderate forest patchiness. Cross-validation and testing on an independent data set in central Louisiana indicated that prediction and transferability of the model were good. Suitable bear habitat decreased from 348 to 345 km2 (0.9%) within the occupied study area and decreased from 34,383 to 33,891 km2 (1.4%) in the unoccupied study area following the hurricanes. Our analysis indicated that bear habitat was not significantly degraded by the hurricanes, although changes that could have occurred on a microhabitat level would be more difficult to detect at the resolution we used. We suggest that managers continue to monitor the possible long-term effects of these hurricanes (e.g., vegetation changes from flooding, introduction of toxic chemicals, or water quality changes).

  19. Seabed erodibility variations on the Louisiana continental shelf before and after the 2011 Mississippi River flood

    Erodibility is critical to the sediment resuspension process but has not been measured systematically in large river-dominated muddy continental shelves before. During early summer of 2011, the Mississippi River experienced a major flood event. This flood provided a unique opportunity to examine how shelf seabed erodibility responded to a large river flood, and the ultimate fate of flood deposition is important to geological and biogeochemical processes (e.g., stratal formation, carbon sequestration). A total of 106 sediment cores were collected on the Louisiana shelf during five cruises in 2010 and 2011, and a new dataset was used to evaluate the response of the seabed to the recent conditions. The localized flood deposit was mainly within tens of kilometers of river sources, and little sediment accumulated on the middle Louisiana shelf. Seabed erodibility was measured using a dual-core Gust Erosion Microcosm System. The erodibility of sediment collected in April 2011 exceeded that for August 2010 and August 2011. The springtime increase in erodibility seemed to be related to the recent presence of energetic waves that mobilized the seabed. Erodibility was highest on the inner shelf southwest of Atchafalaya Bay, intermediate on the middle shelf, lowest in the Mississippi Canyon, and highly variable on the Mississippi subaqueous delta. These spatial patterns were influenced by proximity to river sources, flood-deposit thicknesses, intensity of wave-driven bed stresses, and bioturbation. The flood-deposit thickness itself, however, was not sufficient to explain all the spatial variations of erodibility after the peak of the Mississippi flood. Comparing values to published data, the depth-varying erodibility on the Louisiana shelf was close to the "low erodibility" level for the York River of Virginia, and similar to the data collected from Baltimore Harbor in Maryland and the main stem of upper Chesapeake Bay. Our findings promote understanding of the resuspension

    Full Text Available Many Cajuns claim their Acadian ancestry, despite the fact that their culture is mixed, originating from the different immigrant groups which have settled in Louisiana (French, Acadian, Spanish, Irish, Black and White Creoles…. This sense of belonging appears through the enhancement of a “blood” filiation with the Acadians from the Canadian Maritimes Provinces, of a common historic memory based on the “Grand Dérangement” experience (the expulsion of the Acadians by the British in 1755 and of the survival theme. The bond felt with the Canadian Acadians is also based on the sharing of common language and values and goes to the perception of physical resemblance. The notion of Acadian Diaspora has grown these last years within the Louisiana French revival Movement, and has been fortified  by the World Acadian Congresses (in 1994 in New Brunswick and in 1999 in Lafayette. Even though this sense of belonging is not expressed by Cajuns as a whole, it represents a criterion of definition increasingly widespread, and has given rise to several recent initiatives in “Cajun Country” (located around Lafayette, such as the creation of the Acadian Memorial, the increase of genealogical societies, the setting of exhibitions about Acadian history, and the development of tourism between Louisiana-French and Canadian-French. However, this identity marker never comes into conflict with Cajuns’ American identity. Just like the Louisiana culture as a whole, the origins of Cajun culture are multiple. The metaphor most often employed to illustrate this process of creolization is of culinary nature. It uses a local specialty, gumbo, from which almost every ingredient reveals a different origin : the basic element, roux, comes from a French technique ; okra is a vegetable imported from Africa ; filé has an Native American origin ; finally, rice and the diverse ingredients incorporated (seafood, poultry, pork or wild game are local products.

    Snake fungal disease (SFD) is a recently documented mycotic disease characterized by scabs or crusty scales, subcutaneous nodules, abnormal molting, cloudiness of the eyes (not associated with molting), and localized thickening or crusting of the skin. SFD has been documented in many species in the Eastern and Midwestern United States within the last decade. SFD has proven lethal in many snakes, and the disease is recognized as an emerging threat to wild snake populations. Here, we describe the first documented case of SFD in Louisiana in a free-ranging wild snake.

    A comparison of background and potential geopressured geothermal development-related subsidence rates is given. Estimated potential geopressured-related rates at six prospects are presented. The effect of subsidence on the Texas-Louisiana Gulf Coast is examined including the various associated ground movements and the possible effects of these ground movements on surficial processes. The relationships between ecosystems and subsidence, including the capability of geologic and biologic systems to adapt to subsidence, are analyzed. The actual potential for environmental impact caused by potential geopressured-related subsidence at each of four prospects is addressed. (MHR)

    Scientists and geographers have provided multiple datasets and maps to document temporal changes in vegetation types and land-water relationships in coastal Louisiana. Although these maps provide useful historical information, technological limitations prevented these and other mapping efforts from providing sufficiently detailed calculations of areal changes and shifts in habitat coverage. The current analysis of habitat change draws upon these past mapping efforts but is based on an advanced, geographic information system dataset that was created by using Landsat 5 Thematic Mapper imagery and digital orthophoto quarter quadrangles. The objective of building this dataset was to more specifically define land-water relationships over time in coastal Louisiana, and it provides the most detailed analysis of vegetation shifts to date. In the current study, we have attempted to explain these vegetation shifts by interpreting them in the context of rainfall records, data from the Palmer Drought Severity Index, and salinity data. During the 23 years we analyzed, total marsh acreage decreased, with conversion of marsh to open water. Furthermore, the general trend across coastal Louisiana was a shift to increasingly fresh marsh types. Although fresh marsh remained almost the same during the 1978-88 study period, there were greater increases during the 1988-2001 study periods. Intermediate marsh followed the same pattern, whereas brackish marsh showed a reverse (decreasing) pattern. Changes in saline (saltwater) marsh were minimal. Interpreting shifts in marsh vegetation types by using climate and salinity data provides better understanding of factors influencing these changes and, therefore, can improve our ability to make predictions about future marsh loss related to vegetation changes. Results of our study indicate that precipitation fluctuations prior to vegetation surveys impacted salinities differently across the coast. For example, a wet 6 months prior to the survey

    This report presents the results of a study of terminated produced water discharge sites in the coastal waters of Louisiana. Environmental recovery at the sites is documented by comparing pre-termination and post-termination (six months and one year) data. Produced water, sediments, and sediment interstitial water samples were analyzed for radionuclides, metals, and hydrocarbons. Benthic infauna were identified from samples collected in the vicinity of the discharge and reference sites. Radium isotope activities were determined in fish and crustacean samples. In addition, an environmental risk assessment is made on the basis of the concentrations of metals and hydrocarbons determined in the samples.

    Yellow-crowned Night-Herons (Nycticorax violaceus), Little Blue Herons (Egretta caerulea), and Green-backed Herons (Butorides striatus) collected in northeastern Louisiana from July-September 1980 exhibited different diets. Yellow-crowned Night-Herons fed mostly on crayfish (74% by weight) and Green-backed Herons fed primarily on fish (93% by weight). The diet of Little Blue Herons was diverse, including fish (61%), crustaceans (11%), insects (13%), and arachnids (14%). Yellow-crowned Night-Herons captured larger prey than did either of the smaller herons. Green-backed Herons took larger prey and a greater range of prey sizes than did the larger Little Blue Herons.

    A 6-month study was begun in April 2001 to determine the concentrations of pesticides or oil and grease in selected stream reaches and lakes within the Ouachita, Tensas, and Black River Basins in northeastern Louisiana. During April through September 2001, six monthly water samples for analysis of pesticides were collected from 22 sites: 17 sites were on 11 streams, and 5 sites were on 5 lakes. During Apirl through July 2001, four monthly samples for analysis of oil and grease were collected from 5 sites: 4 sites were on three streams, and 1 site was on a lake. A total of 131 water samples were analyzed for 17 pesticides (15 insecticides and 2 herbicides). The following classes of pesticides, as classified from the Pesticide Analysis (U.S. Environmental Protection Agency Region 6 Laboratory), are reported: organochlorine, nitrogen-phosphorus, and carbamate. The 8 pesticides detected in samples, in decreasing frequency, were as follow: atrazine, molinate, methyl parathion, 4,4'-DDT, carbofuran, diazinon, toxaphene, and 4,4'DDE. Organochlorine pesticides (insecticides) represented the majority (12 out of 17) of the pesticides analyzed. Of those 12 organochlorine pesticides, only 3 (4,4'-DDT, 4,4'-DDE, and toxaphene) were detected in the 131 samples. Of the organochlorine pesticides, 4,4'-DDT was detected most frequently (in 11 percent of the samples), and concentrations ranged from 1.22 to 4.70 ng/L (nanograms per liter). Nitrogen-phosphorus pesticides were the most frequently detected and abundant pesticides. Of all the pesticides analyzed, atrazine and molinate (nitrogen-phosphorus herbicides) were the pesticides most frequently detected (in 93 and 21 percent of the samples), had the highest and most wide-ranging concentrations (10.8 to 15,100 ng/L and 10.0 to 11,600 ng/L), and were most widely distributed throughout the study area. Carbofuran, a carbamate insecticide, was detected at 8 of the 22 pesticide data-collection sites and in 9.2 percent of the 131 samples

    2006-01-01

    The timing, magnitude, and rate of wetland loss were described for five wetland-loss hotspots in the Terrebonne Basin of the Mississippi River delta plain. Land and water areas were mapped for 34 dates between 1956 and 2004 from historical National Wetlands Inventory (NWI) datasets, aerial photographs, and Landsat Thematic Mapper (TM) satellite images. Since 1956, the emergent land area at the five study areas in south-central Louisiana has decreased by about 50%. Comparison of the water-area curve derived from the 29 TM images with water-level records from the nearby Grand Isle, Louisiana tide gauge (NOS #8761724) clearly shows that changes in land and water areas fluctuate in response to variations in regional water levels. The magnitude of water-area fluctuations decreased from the 1980s to the 1990s as former areas of wet marsh within and immediately adjacent to the wetland-loss hotspots became permanently submerged. The most rapid wetland loss occurred during the late 1960s and 1970s. Peak wetland-loss rates during this period were two to four times greater than both the pre-1970s background rates and the most recent wetland-loss rates. These results provide constraints on predicting future delta-plain wetland losses and identify Landsat TM imagery as an important source for analyzing land- and water-area changes across the entire delta plain.

  14. Implications of Texture and Erodibility for Sediment Retention in Receiving Basins of Coastal Louisiana Diversions

    2016-01-01

    Full Text Available Although the Mississippi River deltaic plain has been the subject of abundant research over recent decades, there is a paucity of data concerning field measurement of sediment erodibility in Louisiana estuaries. Two contrasting receiving basins for active diversions were studied: West Bay on the western part of Mississippi River Delta and Big Mar, which is the receiving basin for the Caernarvon freshwater diversion. Push cores and water samples were collected at six stations in West Bay and six stations in Big Mar. The average erodibility of Big Mar sediment was similar to that of Louisiana shelf sediment, but was higher than that of West Bay. Critical shear stress to suspend sediment in both West Bay and Big Mar receiving basins was around 0.2 Pa. A synthesis of 1191 laser grain size data from surficial and down-core sediment reveals that silt (4–63 μm is the largest fraction of retained sediment in receiving basins, larger than the total of sand (>63 μm and clay (<4 μm. It is suggested that preferential delivery of fine grained sediment to more landward and protected receiving basins would enhance mud retention. In addition, small fetch sizes and fragmentation of large receiving basins are favorable for sediment retention.

    Over 345,000 ha of forested swamps occur throughout the Mississippi River Deltaic Plain. Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available science, suggestions for policy change, and a multidisciplinary (multi-responsibility) approach were needed to address these issues [in the context of private land]. In response, the Louisiana Governor's office formed a Coastal Wetland Forest Conservation and Use Science Working Group (SWG) and an associated Advisory Panel to provide the Governor with information and suggestions of strategies for environmental and economic utilization, conservation, and protection of Louisiana's coastal wetland forest ecosystem in the long-term. The process of engaging scientists, resource managers, and other stakeholders in this effort is described, and the recommendations of the SWG are presented relative to forestry practices and the potential for sustainable management of coastal wetland forests.

  16. Potentiometric-level monitoring program - Mississippi and Louisiana: annual status report for fiscal year 1983

    International Nuclear Information System (INIS)

    Potentiometric-level data presented in this report were collected from October 1982 to September 1983 at 62 wells in Mississippi and Louisiana near Richton and Vacherie Domes, respectively. Six wells were added to the monitoring program during this period, and one previously measured well was damaged and has been deleted from the monitoring program. Analysis of the data indicates that most of the potentiometric-level changes recorded during fiscal year 1983 were small (less than 2 feet) and attributable to seasonal fluctuations. Of the 62 wells monitored, 18 exhibited potentiometric-level changes in excess of 2 feet. In Mississippi, the data generally indicate that a long-term, potentiometric-level increase is occurring in the Sparta, Kosciusko, Hattiesburg, Wilcox, and Citronelle Formations. Only seasonal fluctuations in potentiometric levels were observed in the caprock, and in the Catahoula and Cockfield Formations. In Louisiana, a long-term, potentiometric-level decline was observed for the Lower Austin Formation while an increase was observed for the Sparta and Upper Austin Formations. Seasonal fluctuations were observed in the Wilcox, Carrizo, and Nacatoch Formations. This work is a continuation of that described in ONWI-478 for fiscal year 1982. 24 references, 2 figures, 3 tables

    Western Louisiana streams and rivers represent relatively uncharted waters with regard to their biota, particularly aquatic macroinvertebrates. Whereas statewide taxonomic surveys have been conducted for several taxa (Dryopid Coleoptera, Odonata, and Plecoptera), peer-reviewed studies on macroinvertebrate communities and their structuring factors are few. We present the findings of three different macroinvertebrate community studies in western Louisiana encompassing 1990-2004. These studies investigated large-scale forest cover removal and localized biotic influences on macroinvertebrate communities. These studies generally were inconclusive with regard to abiotic anthropogenic disturbances; instead, strong seasonal and spatial patterns combined with wide tolerances to stream physio-chemistry appeared to be more important factors. However, strong localized biotic effects did appear to significantly alter macroinvertebrate communities. Further, a paucity of classic shredding organisms was noted in each study suggesting a unique community composition in these streams in comparison to neighboring regions. We believe geologic phenomenon may have acted as an evolutionary filter that produced a macroinvertebrate community generally tolerant of abiotic disturbance, but not as of yet, tolerant to biotic disturbances.

    Many barrier islands in the United States are eroding and losing elevation substantively because of storm surge, waves, and sea-level changes. This is particularly true for the deltaic barrier system in Louisiana. Breton Island is near the mouth of the Mississippi River at the southern end of the Chandeleur barrier island chain in southeast Louisiana. This report expands on previous geomorphic studies of Breton Island by incorporating additional historic and recent datasets. Multiple analyses focus on longand short-term shoreline change, as well as episodic events and anthropogenic modification. Analyses periods include long term (1869–2014), long-term historic (1869–1950), post-Mississippi River-Gulf Outlet (1950–2014), pre/post-Hurricane Katrina (2004–5), and recent (2005–14). In addition to shoreline change, barrier island geomorphology is evaluated using island area, elevation, and sediment volume change. In the long term (1869–2014), Breton Island was affected by landward transgression, island narrowing, and elevation loss. Major storm events exacerbated the long-term trends. In the recent period (2005–14), Breton Island eroded at a slower rate than in the long-term and gained area and total sediment volume. The recent accretion is likely because of the lack of major storms since Hurricane Katrina in 2005.

  19. The value of wetlands in protecting southeast louisiana from hurricane storm surges.

    Directory of Open Access Journals (Sweden)

    Edward B Barbier

    Full Text Available The Indian Ocean tsunami in 2004 and Hurricanes Katrina and Rita in 2005 have spurred global interest in the role of coastal wetlands and vegetation in reducing storm surge and flood damages. Evidence that coastal wetlands reduce storm surge and attenuate waves is often cited in support of restoring Gulf Coast wetlands to protect coastal communities and property from hurricane damage. Yet interdisciplinary studies combining hydrodynamic and economic analysis to explore this relationship for temperate marshes in the Gulf are lacking. By combining hydrodynamic analysis of simulated hurricane storm surges and economic valuation of expected property damages, we show that the presence of coastal marshes and their vegetation has a demonstrable effect on reducing storm surge levels, thus generating significant values in terms of protecting property in southeast Louisiana. Simulations for four storms along a sea to land transect show that surge levels decline with wetland continuity and vegetation roughness. Regressions confirm that wetland continuity and vegetation along the transect are effective in reducing storm surge levels. A 0.1 increase in wetland continuity per meter reduces property damages for the average affected area analyzed in southeast Louisiana, which includes New Orleans, by $99-$133, and a 0.001 increase in vegetation roughness decreases damages by $24-$43. These reduced damages are equivalent to saving 3 to 5 and 1 to 2 properties per storm for the average area, respectively.

    The scientific literature concerning the public health response to the unprecedented hurricanes striking the Gulf Coast in August and September 2005 has focused mainly on assessing health-related needs and surveillance of injuries, infectious diseases, and other illnesses. However, the hurricanes also resulted in unintended hazardous substances releases in the affected states. Data from two states (Louisiana and Texas) participating in the Hazardous Substances Emergency Events Surveillance (HSEES) system were analyzed to describe the characteristics of hazardous substances releases in industrial settings associated with Hurricanes Katrina and Rita. HSEES is an active multi-state Web-based surveillance system maintained by the Agency for Toxic Substances and Disease Registry (ATSDR). In 2005, 166 hurricane-related hazardous substances events in industrial settings in Louisiana and Texas were reported. Most (72.3%) releases were due to emergency shut downs in preparation for the hurricanes and start-ups after the hurricanes. Emphasis is given to the contributing causal factors, hazardous substances released, and event scenarios. Recommendations are made to prevent or minimize acute releases of hazardous substances during future hurricanes, including installing backup power generation, securing equipment and piping to withstand high winds, establishing procedures to shutdown process operations safely, following established and up-to-date start-up procedures and checklists, and carefully performing pre-start-up safety reviews.

We constructed a network of 13 PEB records with excess 210Pb-derived chronologies to establish the development of low-oxygen and hypoxic conditions over a large portion of the modern dead zone for the last 100 years. The PEB index record indicates that areas of low-oxygen bottom water began to appear in the early 1910s in isolated hotspots near the Mississippi Delta and rapidly expanded across the entire Louisiana shelf beginning in the 1950s. Since ???1950, the percentage of PEB species has steadily increased over a large portion of the modern dead zone. By 1960, subsurface low-oxygen conditions were occurring seasonally over a large part of the geographic area now known as the dead zone. The long-term trends in the PEB index are consistent with the 20th-century observational and proxy data for low oxygen and hypoxia. ?? 2009 US Government.

    The authors conducted a review of 318 investigative reports of animal exposures recorded from November 2004 through April 2008. These reports were gathered as components of the rabies surveillance program in Louisiana. The reports were recorded by employees of the Louisiana Office of Public Health. Results were summarized and analyzed using the Centers for Disease Control and Prevention's (CDC) EpiInfo statistical software. The most common victims were children, most often exposed to a pet that was familiar. In children victimized by pets, males were much more likely to be involved. Children most often suffered injuries to the head and upper torso. Exposures to bats and skunks characterized the greatest risks for rabies transmission, but potential for exposure to rabies from pet species remained a reality. Pit bull type dogs were most frequently involved in dog bite exposures. Requests for animal rabies testing peak in the summer months. The increased risk to children demonstrates a need for public education, animal control programs, and evaluation of risk from certain breeds. Promotion of rabies vaccine compliance is of utmost importance to public health. PMID:19927939

    2009-01-01

    The U.S. Geological Survey (USGS) assessed changes in land and water coverage in coastal Louisiana within 2 months of Hurricane Gustav (September 1, 2008) and Hurricane Ike (September 13, 2008) by using Landsat Thematic Mapper (TM) satellite imagery. The purpose of this study was twofold: (1) to provide preliminary information on land-water area changes in coastal Louisiana shortly after Hurricanes Ike and Gustav made landfall and (2) to contrast these changes with prior, widespread land area changes caused by Hurricane Katrina (August 29, 2005) and Hurricane Rita (September 24, 2005) 3 years earlier. Hurricane Gustav's physical surge impacts were not as severe as those observed from Hurricane Katrina. The largest observed changes were the reversion of recovery vegetation in Upper Breton Sound to an immediate post-Katrina appearance. Hurricane Ike's surge impacts were similar, although of somewhat lesser magnitude than Hurricane Rita's surge impacts. Major surge-removed marsh occurred in similar locations with similar morphologies from the two westward tracking storms. Although the net reduction in land from 2004 to 2008 (849.5 km2) exceeded that from 1978 to 2004 (743.3 km2), it is likely that the 2004-08 estimate will decrease, given time for the coast to recover from those hurricane seasons. Nevertheless, it is likely that the cumulative loss from these hurricane seasons will remain significant. Estimation of permanent losses cannot be made until several growing seasons have passed and the transitory impacts of the hurricanes are accounted for.

    The objectives of this article are to describe the severe acute respiratory illness (SARI) surveillance implemented in Louisiana during the 2013-2014 influenza season, present the epidemiology of reported SARI cases, and identify ways to improve this system by incorporating formal SARI surveillance into the influenza surveillance program. Of the 212 SARI cases, 181 (85%) had at least one underlying medical condition, 54 (25.7%) had two conditions, 43 (20.3%) had three conditions, and 25 (11.8%) reported four or more. The most common four underlying conditions were: obesity (43.4%), chronic cardiac conditions (39.6%), diabetes (29.7%), and chronic pulmonary conditions (26.9%). While obesity was the most reported underlying condition, it was three times more likely to be reported in less than 65 years old rather than those >65. Continuation of SARI data collection in future seasons will allow comparisons regarding severity, populations affected, and identify risk factors most commonly associated with severe illness. Reporting of SARI cases also increased influenza-associated adult mortality reporting to the Office of Public Health's Office of Infectious Diseases Epidemiology (ID Epi). Though all influenza-associated mortality is reportable in Louisiana, adult mortality was reported rarely prior to the 2013-2014 season. PMID:27159455

  5. U.S. Supreme Court refuses to review decision invalidating provisions in Louisiana parental consent law.

    1997-10-31

    On October 20, 1997, the US Supreme Court refused to review an April decision of the US Court of Appeals finding that parental consent provisions in Louisiana's abortion law posed an unconstitutional "undue burden" on minors seeking abortions. Louisiana has required consent of one parent with a court bypass procedure since the early 1980s, but the legislature amended this legislation in 1995 to give judges wide latitude to deny young women abortions, breach their confidentiality, and permit unspecified time parameters in making a decision. A District Court found the amendments in conflict with established federal court precedent, and the Appeals Courts agreed and also found that the lack of guarantee for a specified time for resolution of a petition was inconsistent with court rulings against such open-ended bypass procedures. The Court also rejected a provision that gave a judge authority to order a young woman to attend evaluation and counseling sessions (again with no time limit) before authorization for abortion would be granted. The panel also struck down a provision that permitted a court to contact the parents of a minor if the court determined that the minor was not mature and that such notification would be in her best interests. It was found that this mandate would unacceptably compromise a petitioner's anonymity.

    The Louisiana coastal zone, comprising the Mississippi River delta plain stretching nearly 400 km from Sabine Pass at the Texas border east to the Chandeleur Islands at the Mississippi border, represents one of North America’s most important coastal ecosystems in terms of natural resources, human infrastructure, and cultural heritage. At the same time, this region has the highest rates of coastal erosion and wetland loss in the Nation due to a complex combination of natural processes and anthropogenic actions over the past century. Comparison of historical maps dating back to 1855 and recent aerial photography show the Louisiana coast undergoing net erosion at highly variable rates. Rates have increased significantly during the past several decades. Earlier published statewide average shoreline erosion rates were >6 m/yr; rates have increased recently to >10 m/yr. The increase is attributable to collective action of storms, rapid subsidence, and pervasive man-made alterations of the rivers and the coast. In response to the dramatic landloss, regional-scale restoration plans are being developed by a partnership of federal and state agencies for the delta plain that have the objectives of maintaining the barrier islands, reducing wetland loss, and enhancing the natural sediment delivery processes. There is growing awareness that the sustainability of coastal Louisiana's natural resources and human infrastructure depends on the successful restoration of natural geologic processes. Critical to the long term success of restoration is scientific understanding of the geologic history and processes of the coastal zone region, including interactions between the rivers, wetlands, coast, and inner shelf. A variety of geophysical studies and mapping of Late Quaternary sedimentary framework and coastal processes by U.S. Geological Survey and other scientists during the past 50 years document that the Louisiana delta plain is the product of a complex history of cyclic delta

    In the late 1970s, test holes were drilled in northern Louisiana in the vicinity of Vacherie and Rayburn`s Salt Domes as part of the Department of Energy`s (DOE) National Waste Terminal Storage (NWTS) (rename the Civilian Radioactive Waste Management (CRWM)) program. The purpose of the program was to evaluate the suitability of salt domes for long term storage or disposal of high-level nuclear waste. The Institute for Environmental Studies at Louisiana State University (IES/LSU) and Law Engineering Testing Company (LETCo) of Marietta, Georgia performed the initial field studies. In 1982, DOE awarded a contract to the Earth Technology Corporation (TETC) of Long Beach, California to continue the Gulf Coast Salt Dome studies. In 1986, DOE deferred salt domes from further consideration as repository sites. This report describes test well plugging and site abandonment activities performed by SWEC in accordance with Activity Plan (AP) 1--3, Well Plugging and Site Restoration of Work Sites in Louisiana. The objective of the work outlined in this AP was to return test sites to as near original condition as possible by plugging boreholes, removing equipment, regrading, and seeding. Appendices to this report contain forms required by State of Louisiana, used by SWEC to document decommissioning activities, and pertinent documentation related to lease/access agreements.

    Wave-current interaction over the Texas-Louisiana shelf, and its effects on the dispersal and mixing of the Mississippi-Atchafalaya river plume, have been investigated using the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) Modeling System. The modeling system is driven by realistic wave and current conditions at the open boundaries and high frequency1-D wind measured from a nearby meteorological station. Skill analysis demonstrates that the model reproduces the wave and salinity fields reasonably well. Waves over the Texas-Louisiana shelf are dominated by locally forced wind seas, and generally propagate in the same direction as the winds. Investigation into the spatial differences in the effect of waves reveals two distinct dynamical regions: the Chenier shelf, the shelf region extending roughly offshore from Sabine Lake to Vermilion Bay, and the Louisiana Bight, the region between the Mississippi Delta and Terrebonne Bay. A variety of model runs are performed, where specific wave processes are either included or excluded, in order to isolate the processes acting in different regions. The Chenier shelf is mainly affected by wave enhanced bottom stress, whereas the Louisiana Bight is mostly affected by the surface wave induced mixing and 3-D wave forces. The wave enhanced bottom stress suppresses cross-shore exchange, and acts to trap more freshwater in the nearshore regions shallower than 50 m over the Chenier shelf. Wave enhanced bottom stress plays only a minor role in the Louisiana Bight, where the surface-trapped Mississippi plume rarely feels the bottom. The surface intensified wave mixing and 3-D wave forces reduce the surface salinity and weaken the stratification in the region associated with the thin recirculating Mississippi plume in the Louisiana Bight. Model results indicate that the surface wave mixing, the 3-D wave forces, and the wave bottom stress exhibit little interaction over the Texas-Louisiana shelf. Finally, we have demonstrated

    In order to prepare middle school teachers for the next generation sciences standards and the new common core, the University of Louisiana at Monroe (ULM) Colleges of Arts and Sciences and Education and Human Development launched the Outstanding in the Field II program. Through the creation of a mesonet with the weather stations at middle school sites, this project aims to foster and enrich the experience of teacher/student-collected data while logging the data into a larger scientific database, producing citizen scientists. By empowering students and teachers to actively participate in 'real science', they generate data to be analyzed from both the physical and life science perspective and thus, highlight the next generation science standards and core disciplinary ideas. This project also promotes collaboration between the life and physical sciences while highlighting scientific practices and cross-cutting concepts within science and literacy. To ensure the successful implementation of the program, faculty and will provide several follow-up workshops during the academic year. These workshops will focus on the common core connections of math and literacy as well as ways in which the project can be supported at each site through face-to-face observations and online collaborations. This year-long program began with a field intensive workshop in July 2012 and enrolled 30 6th, 7th, and 8th science teachers from the Northeast region of Louisiana to provide a genuine scientific experience that would be taken back and applied within the classroom. By becoming students, teachers began by collecting data in the field and establishing and refining the intricate connection between real- world experiments and science taught in classrooms. . They returned to the ULM campus to build and deploy weather stations. Teachers were then tasked with the development of a plan to install the weather station and collect data at their school site with emphasis on implementation within their

  17. Remotely sensed imagery revealing the effects of hurricanes Gustav and Ike on coastal Louisiana

    Science.gov (United States)

    2010-01-01

    Hurricane Gustav, a category 2 storm with 170 kilometers per hour (km/h) winds, approached the Louisiana coast from the south-southeast, making landfall near Cocodrie, La., on September 1, 2008 (Beven and Kimberlain, 2009); Hurricane Ike, a category 2 storm with 175 km/h winds, approached the Texas coast from the southeast, paralleling offshore of the Louisiana coast, before making landfall along the north end of Galveston Island, Tex., on September 13, 2008 (Berg, 2009). Hurricane Ike's large wind field elevated water levels, increasing coastal flooding well before making landfall (Berg, 2009). An initial land area change assessment, based on comparison of Landsat Thematic Mapper (TM) satellite imagery, acquired before 2006 and after the 2008 landfalls of Hurricanes Gustav and Ike and classified to identify land and water, reported that the water area increased by 323 square kilometers (km2) in coastal Louisiana as a result of the storms (Barras, 2009). The land area decrease of 195 km2 was less than the 513 km2 decrease reported between 2004 and 2006 (Barras and others, 2008) after the landfalls of Hurricane Katrina, a strong category 3 storm that made landfall near Buras, La., on August 29, 2005, and Hurricane Rita, a category 3 storm that made landfall just west of Johnsons Bayou, La., on September 29, 2005. The 2004 to 2006 land area decrease is 49 km2 less than the 562 km2 initial change estimate based on satellite imagery obtained two months after the 2005 storms (Barras, 2007a). The comparison area used to identify the 2004 to 2006 land area change matches the extent of historical land and water data used to quantify coastal land loss from 1956 to 2006 (Barras and others, 2008) and is 3,841 km2 less than the 33,457.7 km2 used for Barras (2006) and Barras (2009). The greater comparison area used for the 2006 to 2008 period (Barras, 2009) resulted in a 2004 to 2006 loss estimate of 525.8 km2, 13.0 km2 greater than the 512.8 km2 estimate reported in Barras
