New PFAS rules set to take effect Aug. 3, among nation’s strictest


Starting Aug. 3, Michigan will have some of the strictest rules in the nation limiting chemical contaminants in drinking water supplies.

Rules governing the presence of seven per- and polyfluoroalkyl (PFAS) chemicals in drinking water will be filed with the Secretary of State’s Office in the coming days after passing through the Legislature’s Joint Committee on Administrative Rules.

The rules governing 2,700 public water supplies exceed federal standards and could mean increased compliance costs for sites that fall short of the standards.
