Delaware
Planned / legislated- 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
Restrictions are set under HB 356 (pending). Federally-required uses. Part 139 commercial airports and military installations, are governed by federal rules and generally remain exempt from any state restriction.
How to get rid of PFAS foam
A program is legislated or authorized but not yet operating. Hold unused PFAS foam in sealed, labeled containers and watch the official page for the program launch; in the meantime a licensed hazardous-waste hauler is the compliant route.
Funding and help
There is no state takeback funding in Delaware 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
Program implementation is pending (Sale ban Jan 1, 2028 (if enacted)).
Destruction & vendors
No state-designated destruction vendor. Awaiting Senate floor vote; no in-force AFFF ban yet. Manufacturer reimbursement model.
Official sources
Delaware 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.
