WASHINGTON _ The number of known military installations with water sources contaminated by cancer-linked firefighting foam is likely to rise, Pentagon officials said Wednesday.
In 2018, the Pentagon reported that 401 sites _ including wells, on-base drinking sources and groundwater _ at its military bases and communities worldwide had tested positive for higher than allowable levels of Per- and polyfluoroalkyl compounds, commonly known as PFAS.
The compounds are concentrated in the Aqueous Film-Forming Foam (AFFF) that the military has sprayed on aircraft fires since the 1970s.
