EPA announces intent to keep PFOA/PFOS MCLs and pursue rulemaking to extend PFAS drinking-water compliance timeline to 2031; reconsider other PFAS components

EPA announced it intends to retain the existing NPDWR maximum contaminant levels (MCLs) for PFOA and PFOS, while pursuing additional rulemaking to extend the compliance timeline (EPA stated intent to move the compliance date to 2031) and to rescind/reconsider determinations for other PFAS components (PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture). For compliance teams, this signals potential changes to implementation timelines and potentially revised scope/requirements for PFAS drinking-water compliance; affected entities should monitor forthcoming proposed and final rulemaking steps described by EPA.
