Recreational water and industrial discharges are regulated by other federal and state agencies across the country. The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts studies to understand the fate and transport of fecal indicator bacteria in surface and groundwater to aid state and federal partners. A variety of standardized protocols are used to quantify fecal indicator bacteria such as Escherichia coli (E. coli), enterococci, fecal coliform bacteria, and total coliform bacteria. Concentrations of fecal indicator bacteria are analyzed for their relation to hydrology, land-use characteristics, and chemical composition and pathogen content of the sampled water. Studies have focused on developing models for total maximum daily load requirements and understanding the impacts of agricultural and storm drains.

Fecal-indicator bacteria and Escherichia coli pathogen data collected near a novel sub-irrigation water-treatment system in Lenawee County, Michigan, June-November 2007
The U.S. Geological Survey, in cooperation with the Lenawee County Conservation District in Lenawee County, Mich., conducted a sampling effort over a single growing season (June to November 2007) to evaluate the microbiological water quality around a novel livestock reservoir wetland sub-irrigation system. Samples were collected and analyzed for fecal coliform bacteria, Escherichia coli (E. coli)AuthorsJoseph W.

Aims: To evaluate the numbers and selected phenotypic and genotypic characteristics of the faecal indicator bacteria Escherichia coli and enterococci in gull faeces at representative Great Lakes swimming beaches in the United States.Methods and Results: E. coli and enterococci were enumerated in gull faeces by membrane filtration.
