The Environmental Working Group and the Social Science Environmental Health Research Institute at Northeastern collaborated to produce an interactive map that combines federal drinking water data and information on all publicly documented cases of PFAS pollution from manufacturing plants, military air bases, civilian airports and fire training sites.
On the map, blue circles show public water systems where PFASs were detected in public drinking water systems – the larger the circle, the more people served by the system. Clicking on a circle brings up detailed information, including contamination levels. Red dots indicate a contamination site in our PFAS Contamination Site Tracker. Clicking on a dot brings up detailed information and links to more information and resources from the Institute.
Of the 47 locations where the source of the contamination is known or suspected, 21 sources are military bases, 20 are industrial facilities and seven are from civilian firefighting sites. Some locations have multiple sources of contamination.
