More than 1,500 drinking water systems across the country may be contaminated with the nonstick chemicals PFOA and PFOS, and similar fluorine-based chemicals, a new EWG analysis shows. This groundbreaking finding comes the same day the U.S. Environmental Protection Agency (EPA) is convening a summit to address PFAS chemicals—a class of toxic chemicals that includes PFOA and PFOS, and that are linked to cancer, thyroid disease, weakened immunity and other health problems.

The Defense Department has for the first time disclosed the locations of military installations where tap water or groundwater on or off base is contaminated with highly toxic fluorinated chemicals. But the list is incomplete, naming only locations where water is polluted above the U.S. Environmental Protection Agency's (EPA) "safe" level for tap water, which is well above levels found safe by independent scientists and regulations in a growing number of states.
