Brunswick Naval Air Station AFFF (PFAS) Release
On August 19, 2024 at approximately 7:30 am, Maine DEP was notified by the Brunswick Fire Department that approximately 1,450 gallons of AFFF concentrate mixed with approximately 50,000 gallons of water was released at the Brunswick Executive Airport at Hangar 4. The release made its way out of the hangar into an oil/water separator and into nearby stormwater ponds. The release of AFFF concentrate mixed with agitated water resulted in the generation of foam at and near the hangar, through the sewer system and the stormwater collection system.
Responders on the scene that morning began coordination internally and with multiple agencies and organizations, ultimately resulting in establishing a Unified Command (UC) on August 20, 2024. Members of the UC include:
- Maine Department of Environmental Protection
- Maine Department of Health and Human Services' Center for Disease Control and Prevention
- Midcoast Regional Redevelopment Authority
- U.S. Environmental Protection Agency
- Town of Brunswick
- U.S. Coast Guard
The Brunswick Naval Air Station is an active remediation site under the Superfund program that is administered by the US EPA, Department of the Navy, and Maine DEP.
