Wisconsin
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.
Wisconsin Statutes section 299.48 (2019 Wisconsin Act 101) ↗
What's still allowed
PFAS-foam use is restricted under Wis. Stat. §299.48 (since Sept 2020); Part 139 airport and military uses remain exempt.
How to get rid of PFAS foam
Use the DNR/DATCP Collection & Disposal Program, free collection (vendor North Shore Environmental); the state pays the vendor, not departments.
Funding and help
Collection and destruction run through the Wisconsin 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
Round 1 collected 28,000+ gallons across 60+ counties; program is funded and ongoing.
Destruction & vendors
Foam in Wisconsin is handled by: North Shore Environmental. 60+ counties in round 1; backlog estimate exceeded.

Wisconsin 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.
