USEPA Sets Limit for E.Coli

EcoliThe U.S. Environmental Protection Agency (USEPA) has updated the Revised Total Coliform Rule for pathogens in drinking water, including setting a limit for Escherichia coli (E.coli) bacteria.  Under the revised rule, about 155,000 public drinking water systems are required to notify the public if a test exceeds the maximum contaminant level (MCL) for E.coli in drinking water.  The revised rule provides incentives for small drinking water systems that consistently meet certain measures of water quality and system performance.  High-risk drinking water systems with a history of non-compliance will be required to perform more frequent monitoring.

The rule change requires each water system facility to notify the public whenever there is a possible health threat, as well as when a facility fails to identify and fix problems. Each system's monitoring requirements will be regulated based on population, system type, and water source type.   Systems will also be required to meet a legal limit of the maximum contaminant level of E.coli present.

Public water systems must comply with the requirements of the Revised Total Coliform Rule beginning April 1, 2016. Until then, the 1989 version of the rule will remain in effect.  To access more information from the USEPA website, click here.
