Hundreds of military installations have either known or likely water contamination caused by runoff from firefighting foam used in response to vehicle and aircraft accidents, according to the Environmental Working Group.
Using Defense Department data, the organization built an interactive map of 305 sites, which are found in all 50 states. Each map dot opens up to information and links on perfluorooctane sulfonate or perfluorooctanoic acid, known as PFAS.
“Of these sites, 138 have not been previously identified on EWG’s map of known PFAS contamination at military bases, civilian airports and industrial sites,” according to a Tuesday new release. “In addition, 42 of these sites were not included on a list of 401 locations the Pentagon gave to Congress of active and former installations where PFAS contamination was known or suspected.”
