Escherichia coli bacteria
Overview
Escherichia coli, estimated by regression equation, water, colonies per 100 milliliters
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.
Water-quality Standards and Criteria
NDEQ primary contact limit in infrequently used waters: 576 cfu/100mL
576 colonies per 100 mL is the single sample maximum for infrequently used recreational waters.
