PBS NewsHour: What are PFASs, the toxic chemicals being found in drinking water?



The researchers suggest the broad spread of PFASs in water sources is partly from fire fighting foams and sprays used in training simulations by the military and airport workers.

“During fire-fighting practice drills, large volumes of these toxic chemicals wash into surface and ground waters and can end up in our drinking water,” Arlene Blum, study co-author and executive director of the Green Science Policy Institute said. “Such persistent chemicals should only be used when essential, and never for training.”
