Quantitative Comparison Of Fecal Coliform And Fecal Streptococci Counts Of Six Ponds In Charlotte Sounty, Virginia, Melissa Dunn Back

Theses & Honors Papers

Performing testing to detect for the presence of fecal coliform and fecal streptococci are the acceptable standard methods for judging the quality of water. Their presence and quantitation are presumed to be a predictive indicator of potentially more serious organisms being present. This study was initiated to look at the differences in fecal coliform counts between irrigation ponds and livestock ponds. The hypothesis was that livestock ponds would have a significantly higher count of fecal coliform and fecal streptococci than irrigation ponds. This hypothesis was accepted. Six privately owned ponds in Charlotte County, Virginia were used to evaluate for the …

Illinois River 2000 Pollutant Loads At Arkansas 59 Bridge, Marc A. Nelson, Thomas S. Soerens

Technical Reports

Automatic water samplers and a U. S. Geological Survey gauging station were established in 1995 on the main stem of the Illinois River at the Arkansas Highway 59 Bridge. Since that time, continuous stage and discharge measurements and water quality sampling have been used to determine pollutant concentrations and loads in the Arkansas portion of the Illinois River. This report represents the results from the measurement and sampling for January 1, 2000 to December 31, 2000

Pride Water Quality Assessment Report: Iv. Nutrient Assessment, Kentucky Water Resources Research Institute, University Of Kentucky

KWRRI Research Reports

The efficient utilization of federal funds in improving the water quality and aquatic habitat of the region requires a mechanism for assessing and evaluating the impacts of the proposed and ongoing projects as well as some mechanism for prioritizing the allocation of additional funds. In order to evaluate the effectiveness of these projects it is important to provide a formal monitoring and assessment program based on sound scientific principles. This report provides an initial 10 year baseline assessment of the existing water quality conditions in the 40 county PRIDE region for the purpose of evaluating the impacts of the PRIDE …

A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio

Biological Sciences Theses & Dissertations

Lake Prince and the Western Branch Reservoir are two eutrophic bodies of water located in Suffolk, Virginia. Lake Prince and its two small tributaries join the Western branch via a constructed spillway. This lake system is a source of water for the surrounding municipalities, and a recreational area for community citizens. In the past, these bodies of water had repeated incidents of low oxygen and nuisance algal blooms, particularly cyanobacteria species. As a result aerators have been installed in the main body of both Lake Prince and the Western Branch Reservoir. In addition, a pipeline has been installed from North …

Land Use Patterns In Relation To Lake Water Quality In The Lake George And Oaks Pond Watersheds, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

There has always been an inexplicable wonder associated with the beauty of Maine lakes. In addition to their aesthetic value, lakes and ponds provide important habitats for aquatic and terrestrial wildlife. The attraction of the lake's natural beauty, however, can increase recreational pressures that may lead to human induced eutrophication. Lake George and Oaks Pond were chosen as the Colby Environmental Assessment Team's (CEAT) study sites due to the concern about potential human induced eutrophication of both water bodies. Lake George and Oaks Pond are situated in southern Somerset County, Maine, and experience heavy recreational and developmental uses. Neither water …

Hydrologic Events And Water Quality In The Pigeon River, Ottawa County, Michigan, Neil W. Macdonald, Richard R. Rediske, Jonathan E. Van Denend

Peer Reviewed Publications

The Pigeon River drains a 16,765-ha agricultural watershed in western Ottawa County, Michigan and discharges into south-central Lake Michigan. Extensive areas of wetlands in the upper watershed were drained in the 1920s, causing significantly altered hydrology characteristics by flashy discharges during storms and periods of snowmelt. We studied stream chemistry and hydrology for a four-year period between September, 1996, and October, 2000, to determine water quality status, to estimate annual nutrient exports, and to evaluate the effects of different seasonal flow types. Results of our study confirmed that the upper reaches of the Pigeon River experience chronically degraded water quality, …

Soil Factors Influencing Eutrophication. In Soilguide. A Handbook For Understanding And Managing Agricultural Soils. (Ed. Geoff Moore), David Weaver, Robert Summers

Bulletins 4000 -

Eutrophication is essentially the nutrient enrichment of waterways leading to algal growth. It must be controlled to maintain sustainable agricultural systems and the main mechanisms of control are stabilising catchment processes and reducing nutrient output.

Eutrophication can be defined as 'the nutrient enrichment of waters which results in the stimulation of an array of symptomatic changes, among which increased production of algae and macrophytes, deterioration of water quality and other symptomatic changes, are found to be undesirable and interfere with water uses' (OECD 1982). The word eutrophic is a Greek word that means 'well fed'. The food referred to is …

Relationships Between Stream Order And Management Priority: A Water Quality Case Study, David Weaver, Adrian Reed, John Grant

Conference papers and presentations

Seagrass, which once dominated the habitat of Oyster Harbour on the south coast of Western Australia has been replaced by macroalgae because of increased nutrient and sediment discharge from the rural dominated catchment. Total Phosphorus (TP), Total Nitrogen (TN), Suspended Sediment (SS) and Electrical Conductivity (EC) concentrations from a catchment – wide (168 sites), event-driven snapshot, water quality monitoring program conducted from 1994 to 1996, were analysed in relation to stream order and published survey data on riparian zone condition. This analysis was performed to examine relationships between stream order, riparian zone condition and water quality, and implications for the …
