Fecal coliform bacteria
Overview
The presence of fecal coliform bacteria in surface water indicates fecal contamination by warm-blooded mammals and possibly indicates the presence of other organisms that could cause disease.
Water-quality standards and criteria are developed by the States, approved by the U.S. Environmental Protection Agency (USEPA), and then promulgated (passed into law) as standards by each State. Graphs on this website allow comparison of measured and computed data to these standards and criteria by plotting them as straight lines. When evaluating data to decide whether water quality is suitable for the intended use, viewers are cautioned to consider the uncertainty associated with these computed data.
