On April 10, 2024, the EPA announced the final National Primary Drinking Water Regulation for six PFAS. The regulation establishes legally enforceable levels for individual PFAS MCLs and a Hazard Index MCL for PFAS mixtures. EPA evaluated over 120,000 comments submitted by the public on the rule proposal and expects that over many years, the final rule will prevent PFAS exposure in drinking water for up to 200 million people, prevent thousands of deaths, and reduce tens of thousands of PFAS-attributable severe illnesses. Additionally, $1 billion of additional funding has been made available through the Bipartisan Infrastructure Law to help states and territories implement PFAS testing and treatment at public water systems and to help owners of private wells address PFAS contamination.
