The known extent of contamination of American communities with the highly toxic fluorinated compounds known as PFAS continues to grow at an alarming rate. As of March 2019, 610 locations in 43 states are now known to be affected, including drinking water systems serving an estimated 19 million people.
The latest update of an interactive map by EWG and the Social Science Environmental Health Research Institute, at Northeastern University, documents publicly known PFAS pollution in public water systems and military bases, airports, industrial plants and dumps, and firefighter training sites.
