Clean Water Standards for PFAS Act of 2025

This legislation, titled the Clean Water Standards for PFAS Act of 2025, aims to significantly enhance the regulation of perfluoroalkyl and polyfluoroalkyl substances (PFAS) under the Federal Water Pollution Control Act. It mandates the Environmental Protection Agency (EPA) to publish human health water quality criteria for all measurable PFAS within three years of the bill's enactment. This action is crucial for establishing clear benchmarks for safe levels of these persistent chemicals in water. The bill establishes specific deadlines for the EPA to finalize effluent limitations guidelines and standards for PFAS discharges from several key industrial categories. These include organic chemicals, plastics, and synthetic fibers electroplating metal finishing textile mills landfills leather tanning and finishing paint formulating plastics molding and forming , with deadlines ranging from September 2026 to September 2028. Furthermore, the legislation requires immediate monitoring of PFAS discharges from these and additional categories, such as pulp and paper mills, airports, and electrical and electronic components, starting from the date of enactment. To support these regulatory efforts, the EPA is directed to promulgate a standardized analytical method for PFAS, specifically Method 1633A or an equivalent, by January 2026. The bill also authorizes substantial appropriations, including $200,000,000 annually for fiscal years 2026 through 2030, for grants to publicly owned treatment works. These grants are intended to fund pretreatment program activities, monitoring, and analysis of local PFAS sources, thereby enhancing their capacity to manage and reduce PFAS contamination.
