Water Systems PFAS Liability Protection Act

This bill protects public water systems, wastewater treatment facilities, and related entities from liability under federal environmental law for PFAS releases, provided they follow all applicable laws during treatment or disposal. It exempts these "protected entities" from cost-recovery claims under CERCLA when handling PFAS in ways consistent with existing water treatment practices, such as managing biosolids, discharging treated water, or disposing of filter media. The exemption does not apply if a facility acts with gross negligence or willful misconduct in handling PFAS. This directly affects water utilities and municipalities managing PFAS-contaminated water or byproducts under current federal and state regulations.
