Puerto Rico
No 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.
What's still allowed
No Puerto Rico firefighting-foam ban; AFFF use is unrestricted under local law. Military and airport uses follow federal rules.
How to get rid of PFAS foam
No territorial takeback, store foam or ship it to a licensed PFAS-disposal facility on the U.S. mainland. Military foam (former Naval Station Roosevelt Roads, Fort Buchanan, Camp Santiago) is handled by DoD / Army Environmental Command under CERCLA.
Funding and help
There is no state takeback funding in Puerto Rico yet. The federal options below apply everywhere.
- 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
Federal PFAS site assessments continue at PR military sites; ~$19M in federal water-infrastructure funding has been allocated for emerging contaminants.
Destruction & vendors
No state-designated destruction vendor. No territorial AFFF program or ban. Severe military-driven PFAS contamination, former Naval Station Roosevelt Roads, Fort Buchanan, Camp Santiago. EPA Region 2 + DoD under CERCLA. Disposal: store or ship to the mainland.

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.
