This legislation aims to solidify federal regulations concerning per- and polyfluoroalkyl substances (PFAS) in drinking water. Its primary purpose is to codify a specific final rule issued by the Environmental Protection Agency (EPA). Specifically, the bill mandates that the EPA's "PFAS National Primary Drinking Water Regulation," published on April 26, 2024, and as it stood on June 25, 2024, shall have the force and effect of law . This action ensures that the established national primary drinking water standards for PFAS are permanently implemented and legally binding across the United States.
