Washington
Active program- EPA set enforceable drinking-water limits for PFOA and PFOS at 4 parts per trillion (2024). A May 2026 proposal would keep those two, extend compliance to 2031, and rescind the others. Proposed, not final.
- Under CERCLA (the Comprehensive Environmental Response, Compensation, and Liability Act), PFOA and PFOS are hazardous substances, so cleanup liability is strict, retroactive, and joint and several.
- Federally required uses at Part 139 airports and military installations follow federal rules regardless of state law.
- The Department of Defense is phasing out AFFF under the NDAA.
Chapter 70A.400 RCW (Engrossed Substitute House Bill 2793, 2018) ↗
What's still allowed
Sale and training use have been banned since 2018/2020; Part 139 airport and military uses remain exempt.
How to get rid of PFAS foam
Use the Dept. of Ecology AFFF Collection & Disposal Program (launched Sept 2025), free pickup, transport, and disposal (Clean Harbors, high-temp incineration at Aragonite, UT), plus replacement support. No cash buyback.
Funding and help
Collection and destruction run through the Washington program; check the official page for what the state covers.
- EPA Emerging Contaminants in Small or Disadvantaged Communities grant ↗, funded by the Bipartisan Infrastructure Law.
- Drinking Water State Revolving Fund ↗, including the infrastructure-law set-aside for emerging contaminants like PFAS.
- FAA airport foam transition support ↗ for Part 139 commercial airports moving off fluorinated foam.
- Fire departments with contaminated water may qualify as claimants in the aqueous film-forming foam (AFFF) settlements.
Future plans
State program funding runs through ~June 2027; projected scope is ~32,000–40,000 gallons across ~80–95 departments.
Destruction & vendors
Foam in Washington is handled by: Clean Harbors, incineration (Aragonite, UT). Launched Sept 2025; free disposal + replacement, no cash buyback. ~32k gal projected scope.
Official sources
Washington official program page ↗A note for smaller departments
Large departments and municipalities usually have legal counsel and a budget to manage PFAS liability. Small and volunteer departments often do not. That makes a documented chain of custody and a certificate of destruction the strongest protection a small department has: proof that the foam was handled lawfully and never released. See liability and litigation.
