"The military is beginning to check whether chemicals from its firefighting foam may have contaminated groundwater at hundreds of sites nationwide, according to the Defense Department.
The Navy began sampling water at bases in December. Eighty five sites will be checked in California alone.
At a naval landing field in Virginia, the U.S. Navy is now giving its personnel bottled water and testing wells in the nearby rural area after the discovery of perfluorinated chemicals in drinking water. Several congressmen are raising concerns about the safety of drinking water near two former Navy bases in suburban Philadelphia because of firefighting foam.
The foam is used at locations where potentially catastrophic fuel fires can occur because it can rapidly extinguish them. It contains perfluorooctane sulfonate and perfluorooctanoic acid, or PFOS and PFOA, both considered emerging contaminants by the U.S. Environmental Protection Agency."
