Suspected source: Firefighting foam used at Brunswick Naval Air Station. Several sites on the former Brunswick naval base, including Building 653, a former AFFF storage facility, and a separate fire training location, had levels of PFC contamination above the EPA HAL.
The Navy has spent more than $100 million investigating and cleaning up pollution on the 3,100-acre station, and still operates a water treatment and monitoring system in the “Eastern Plume” contamination area. The Navy transferred much of the property to the town of Brunswick and the Midcoast Regional Redevelopment Authority after closing the base in 2011.
