EPA announced it will retain the National Primary Drinking Water Regulation (NPDWR) maximum contaminant levels (MCLs) for PFOA and PFOS, but intends to extend the associated compliance deadline to 2031 through future rulemaking. EPA also signaled its intent to rescind and reconsider the regulatory determinations for PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture approach (PFHxS, PFNA, HFPO-DA, PFBS). Compliance teams for public water systems and regulated entities should monitor forthcoming proposed and final rulemaking for changes to compliance timelines and the scope of PFAS regulated under the NPDWR.
EPA announced it will retain the PFAS NPDWR maximum contaminant levels (MCLs) for PFOA and PFOS, but intends to pursue rulemaking to extend the compliance timeline to 2031. EPA also stated it intends to rescind and reconsider regulatory determinations affecting additional PFAS (PFHxS, PFNA, HFPO-DA (GenX)) and the Hazard Index mixture approach (PFHxS, PFNA, GenX, PFBS). The agency indicated it plans to propose the changes in the fall and finalize in spring 2026. Water utilities and affected stakeholders should plan for a potential schedule change (timeline extension) and possible scope changes for the additional PFAS/Hazard Index components, and monitor the forthcoming proposed and final rulemaking actions.
