Survival and Overland Transport of Fecal Coliform under Canadian Prairie Conditions
In-field winter feeding of cattle is becoming a common practice in the Canadian Prairie. Cattle feeding in-field during winter provides economic advantages to agricultural producers over feeding the cattle in confined corrals by eliminating the extra work and cost associated with feed transport and …

Examining the Influence of Wildlife Population and Fecal Coliform Density Variability on Virginia Bacterial TMDL Development
… conducted with estimates of population and fecal coliform production. A sensitivity analysis was performed on the bacteria TMDL development process and the HSPF (Hydrological Simulation Program-FORTRAN) model to determine how wildlife population and fecal coliform density variability impacts …

The usefulness of multiple antibiotic resistance (MAR) indexing technique in differentiating fecal coliform bacteria from different sources
Pollution of water sources with human fecal matter and associated intestinal pathogens poses a great risk to public health. Fecal contamination of water is not the only problem to communities that consume untreated water. The extent of the microbial contamination of water sources also needs to be …

Fecal Coliform as an Indicator of Water Quality and Recreational Carrying Capacity At Ozark National Scenic Riverways
… relationship between levels of canoe use and fecal coliform densities. Water quality data were collected at seven locations on the Current and Jacks Fork Rivers during the summer of 1985. Water quality tests performed were dissolved oxygen, conductivity, nitrates, pH, temperature, fecal …

American Alligator Fecal Coliform and Pathogen Identification, Genotypic Fingerprinting, and REP-PCR Bacterial Source Tracking in South Carolina
… (i.e. cold-blooded) wildlife sources, including fecal coliform identification, genotypic fingerprinting, and bacterial source tracking. The overall goals were to identify, fingerprint, and detect American alligator (<em>Alligator mississippiensis</em>) fecal coliform bacteria in surface waters, …

The Use of Selected Water Quality Parameters to Identify Fecal Coliform Sources in Support of the Sinking Creek Total Maximum Daily Load.
… A Total Maximum Daily Load (TMDL) for fecal coliforms was developed. The purpose of this study was to investigate the use of water quality parameters to identify areas that contribute to the fecal coliform loading. Concentrations of nitrate-N, orthophosphates, BOD, alkalinity, hardness, …

Determination of Urban Land Use Variables That Accurately Predict Fecal Coliform Levels In Shellfish Harvesting Waters Within Estuarine Salt Marsh Ecosystems of the Southeastern United States of America.
… the parcel level within a coastal watershed, and fecal coliform bacteria levels in the adjoining receiving waters. Regression modeling was used to determine a simple model to represent the relationship between fecal coliform and urban land use metrics. Sources used included a parcel level dataset …

Relationship between Land Use and Surface Water Quality in a Rapidly Developing Watershed in Southeast Louisiana
… had low dissolved salt, nutrient, and fecal coliform concentrations and high dissolved oxygen levels. Waterbodies within the urban region (> 28% urban land cover within the sub-watershed) of the parish had significantly greater dissolved salt, nutrient, and fecal coliform concentrations …

Spring Studies and A Decision-Making Process to Guide Groundwater Contamination Prevention in an Agricultural Karst Basin
… and springs contribute to the elevated levels of fecal coliform bacteria in the groundwater. Six sites in Buckeye Creek basin were monitored for fecal coliform contamination and then analyzed in order to determine where best management practices (BMPs) could result in the most effective water …

Sediment Transport and Pathogen Indicator Modeling in Lake Pontchartrain
… that would determine the fate and transport of fecal coliform bacteria in the lake. The processes included hydrodynamics, waves, sediment transport, and the decay and transport of the fecal coliforms. Wind and tidal effects were accounted along with the freshwater inflows. All the components of …

Evaluation of Constructed Wetlands for the Waste Management of a Large Scale Swine Production Unit
… oxygen demand, and to reduce the levels of the Fecal Coliform Bacteria from a swine operation was evaluated. The indicator of proper waste purification will be the result of testing for the following: ammonia nitrogen, nitrate nitrogen, total phosphorus, total suspended solids, dissolved solids, …

Stormwater Treatment by Two Retrofit Infiltration Practices
… sediment, total nitrogen, total phosphorus, fecal coliform bacteria and E-coli bacteria. The inflow and outflow concentrations and loads, as well as total inflow and outflow volumes and peak flow rates, were then compared to evaluate how well each BMP reduces stormwater flows, decrease peak …

Comparing Alternative Methods of Simulating Bacteria Concentrations with HSPF Under Low-Flow Conditions
… completely. Under these "low flow" conditions, fecal bacteria directly deposited in the stream dominate in-stream bacteria loads. When developing a Total Maximum Daily Load (TMDL) to address a bacterial impairment in an upland, rural watershed, direct deposit (DD) fecal bacteria sources …

Water Quality Study of Southshore of Lake Pontchartrain
… Lake Pontchartrain. Under dry weather conditions Fecal Coliform values exceeded the limit of 200 MPN/100mL at 3 of 16 stations. Fecal Coliform counts were found to be "wet" weather-dependent and unsuitable for primary contact recreation for at least three to four days following a pumping/rain …

Impact of Animal Waste Best Management Practices on the Bacteriological Quality of Surface Water
… including the watershed outlet, and analyzed for fecal coliform, total coliform, and fecal streptococcus bacteria. Other data compiled from the watershed included hydrologic, meteorologic, geologic and land use data, also collected on a regular basis. Data were collected continuously throughout …
