Settlement eligibility & deadlines

Action Fund Claims

Due June 30, 2026 · Fund: $1.185B

Phase 2 water systems (those serving >3,300 people, or those that detected PFAS more recently) must submit Action Fund claim forms covering remediation and treatment costs.

If you miss it: Forfeit your system's share of the DuPont/Chemours/Corteva treatment fund.

Treatment & remediation cost claims

Due July 31, 2026 · Fund: $10.5–12.5B

Public water systems with confirmed PFAS detections must file via the official PFAS Water Settlement portal. The fund is the largest PFAS settlement pool in U.S. history.

If you miss it: Forfeit your share of the 3M settlement and waive future direct-action rights against 3M for PFAS.

Applications for disadvantaged / under-resourced systems

Due August 1, 2026 · Fund: Discretionary

Supplemental fund for systems facing capacity, affordability, or technical barriers. Documentation burden is highest but eligibility is broader than the main funds.

1. System identification

• PWSID (Public Water System ID)

• Service area population and number of connections
• Source water type (groundwater, surface water, mixed)

2. PFAS detection evidence

• Any state-mandated PFAS sampling results (state primacy agency reports)
• Independent or pre-rule monitoring data (utility's own historical samples)
• Chain-of-custody records and lab certifications (EPA Methods 533, 537.1, or 1633)

3. Treatment cost documentation

• Existing treatment capital cost (GAC, ion exchange, RO/NF) — invoices, contracts
• Annual O&M cost for PFAS treatment (media changeouts, energy, disposal)
• Engineering studies and treatability evaluations
• Pilot test reports if applicable

4. Source attribution & impact

• Identified upstream PFAS sources (AFFF sites, industrial dischargers, landfills)
• Distance to known contamination sites (EPA ECHO, state inventories)
