In a March report provided to the House Armed Services Committee, the Pentagon for the first time publicly listed the full scope of the known contamination. The Defense Department identified 401 active and Base Closure and Realignment installations in the United States with at least one area where there was a known or suspected release of perfluorinated compounds.
These included 36 sites with drinking water contamination on-base, and more than 90 sites that reported either on-base or off-base drinking water or groundwater contamination, in which the water source tested above the Environmental Protection Agency’s acceptable levels of perfluorooctane sulfonate or perfluorooctanoic acid, also known as PFOS and PFOAs.
The man-made chemicals, which can be used to make items heat or water resistant, are found in everyday household, food and clothing items, even take-out food wrappers.
At military bases, however, they are concentrated in the foam used to put out aircraft fires.
