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.
