An Act To Protect The Drinking Water For Consumers Of Certain Water Systems By Establishing Maximum Contaminant Levels For Certain Perfluoroalkyl And Polyfluoroalkyl Substances

LD 1326 establishes specific maximum contaminant levels for PFAS chemicals (used in products like non-stick coatings and firefighting foam) in drinking water for community water systems (like municipal supplies) and nontransient noncommunity systems (such as schools and childcare facilities). It sets strict limits, including 4 parts per trillion for PFOA and PFOS, and requires water systems to begin monitoring for these chemicals starting January 1, 2026, with testing frequency based on results (quarterly if levels exceed 50% of limits, annual if below). If contamination exceeds limits, systems must implement treatment by 2029 and notify users about health risks until resolved. The law aims to protect public health by setting enforceable standards for PFAS in drinking water sources.
