Water samples tested after Maine firefighting foam spill, below guidelines for dangerous chemicals
Maine environmental officials say all water samples analyzed so far after the state’s largest recorded accidental spill of firefighting foam are below its guidelines for potentially dangerous chemicals
BRUNSWICK, Maine — Maine environmental officials said all water samples analyzed so far in the wake of the state's largest recorded accidental spill of firefighting foam are below its guidelines for potentially dangerous chemicals.
A fire suppression system at a hangar at Brunswick Executive Airport discharged more than 1,400 gallons (5,300 liters) of the foam concentrate mixed with 50,000 gallons (190,000 liters) of water at the former Navy base on Aug. 19. The discharge triggered an investigation and also prompted a warning from the Maine Center for Disease Control and Prevention to limit consumption of freshwater fish from nearby bodies of water.
The foam contained chemicals known as PFAS that are associated with health problems including cancer. The foam was removed after the accident.
The Maine Department of Environmental Protection sampled 34 water supplies in the area of the spill and has contacted property owners to discuss the results, the agency said Thursday. The water supplies will be tested every three months for a year, the agency said.
The department has also evaluated eight rounds of surface water results from the nearby watershed and found concentrations are continuing to decline, the agency said in a statement.
“PFAS levels in the watershed have not yet returned to pre-spill concentrations and testing of surface water will continue to track the trends,” the department's statement said.
Per-and polyfluoroalkyl substances, or PFAS, are found in everything from food packaging to clothing. The Environmental
