On May 14, 2025, the U.S. Environmental Protection Agency (EPA) announced that it will keep the current National Primary Drinking Water Regulations (NPDWR) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), setting nationwide limits for these “forever chemicals” in drinking water. At the same time, the EPA signaled its intent to rescind the recently established regulations for additional PFAS compounds (PFHxS, PFNA, and HFPO-DA [GenX]), as well as the Hazard Index mixture of these three plus PFBS. The agency also extended the compliance timeline for public water systems from 2029 to 2031. A proposed rule is expected this fall, with a final version anticipated in spring 2026.
States are Stepping Up, and Why It Matters
With the EPA considering a rollback of federal PFAS drinking water rules, states are increasingly taking matters into their own hands. Over the past year, more than 250 PFAS-related bills have been filed across 36 states. These measures range from banning PFAS in consumer products to establishing stricter drinking water limits and expanding funding for site remediation and cleanup.
Many states are already moving ahead with tougher regulations, creating what could become a patchwork of standards nationwide. For water utilities and state agencies, this may mean adopting different compliance strategies across jurisdictions. For manufacturers, retailers, and product developers, rapid state-level bans or limits could precede and reshape future federal requirements, making proactive adaptation essential.
