PFAS Drinking Water Standards Ruleset


Michigan Department of Environment, Great Lakes, and Energy (EGLE) adopted a ruleset that took effect August 3, 2020. The rules provide drinking water standards for public water systems to achieve. Michigan’s first-ever regulations limiting seven PFAS chemicals in drinking water covers roughly 2,700 public water supplies around the state and exceed the current US Environmental Protection Agency (EPA) guidance on the chemicals. The levels are set at 6 ppt for PFNA, 8 ppt for PFOA, and 16 ppt for PFOS. For more information, see the Michigan PFAS Action Response Team (MPART) website on PFAS.
