Environmental Working Group recently published a map of 305 military installations that used the firefighting foams made with per- and polyfluoroalkyl substances (PFAS), which have likely contaminated drinking water or ground water on or around the bases.

In addition, 42 of these sites were not included on a list of 401 locations the Pentagon gave to Congress
