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 …

Evaluating Coliform Monitoring Strategies for Contamination Scenarios in a Distribution System Model
… to test these samples for the presence of total coliforms to comply with the Total Coliform Rule. How and where they take these samples is not specified. The Total Coliform Rule is currently undergoing review and revision. One possible revision is more specific rule language or guidance of where …

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
… microbial risk-free water. For decades fecal coliform counts have been used as indicators of fecal contamination and the potential presence of intestinal pathogens in surface waters. However, fecal coliforms fail to provide information about the source of fecal contamination. Knowing the …

Evaluation of methodology for detection and quantification of coliform bacteria and their survival in soil and water.
… the risk of contamination. The presence of coliform bacteria and in particular E. coli, in private water supplies is an indication of the potential for the water supply to be contaminated with pathogenic microorganisms. With the increasing occurrence of severe illness from pathogens such as …

Fecal Coliform as an Indicator of Water Quality and Recreational Carrying Capacity At Ozark National Scenic Riverways
… 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 coliform and …

Groundwater contamination by selenium, nitrate, coliform bacteria, and volatile organic compounds in the Las Vegas Valley, Nevada, shallow aquifer zone
… Nevada, was sampled for selenium, nitrate, coliform bacteria and 37 volatile organic compounds. A distinct pattern of elevated levels of selenium, nitrates, and chloroform was observed in the developed portions of the valley. Evidence suggests that the probable sources for these contaminants …

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, and …
