GREENSBORO, N.C. (AP) — Officials in a North Carolina city see an area around an airport as the potential source of a contaminant in its drinking water.
The News & Record of Greensboro reports city officials are pointing specifically to a place near Piedmont Triad International Airport where firefighters used a synthetic foam containing PFOS to control fuel-based fires.
PTI also conducts fire-training drills using firefighting foam once a year on its runway, meaning additional PFOS is getting into a nearby stream or ground water.
An online search describes Perfluorooctanesulfonic acid, or PFOS, as the key ingredient in stain repellants.
