Both major water-provider settlements have now closed to new claims: the DuPont/Chemours/Corteva fund ($1.185B) on June 30, 2026, and the $10.5–12.5 billion 3M Phase 2 Action Fund — the largest PFAS settlement in U.S. history — on July 31, with the Special Needs Fund following on August 1. What remains for every system over the limit is the EPA compliance deadline of April 2029.
The official portal remains at pfaswatersettlement.com. PFAS Comply is not the settlement administrator and does not take a contingency on filings.
Already filed — directly or through counsel? You're set; do not file again. Duplicate submissions can delay processing. If you're unsure which form is on file, confirm with the settlement administrator. And a detection above the MCL is not a current violation — the federal compliance deadline is April 2029. Eligibility is about settlement funds, not a compliance problem.

Kept for reference. The 3M and DuPont filing windows have closed, but the same records — detection evidence, treatment costs, source attribution — are what state revolving fund and EC-SDC grant applications ask for, and section 3 (treatment costs) is still the one that takes longest to pull together.
