Relating to: programs and requirements to address PFAS.

AB 131 establishes a municipal grant program to test for PFAS (perfluoroalkyl and polyfluoroalkyl substances) in public water systems and fund source reduction measures. It allows water utilities to use customer service fees to cover up to half the cost of PFAS source reduction for connected customers, if cheaper than facility upgrades. The bill also creates eligibility rules for disadvantaged communities extending service due to PFAS contamination and directs PFAS contamination claims to an existing landowner grant program. These provisions directly affect municipal water systems, public utilities, and communities addressing PFAS in drinking water.
