Per- and polyfluoroalkyl substances

The Social Discovery of a Class of Emerging Contaminants

Warminster, Warrington and Horsham (Bucks County), Pennsylvania

Suspected contamination source: Firefighting foam used at former Naval Air Warfare Center in Warminster and former Naval Air Station Joint Reserve Base in Horsham, along with the active Horsham Air Guard Station and Willow Grove Naval Air Station Joint Reserve Base (NASJRB) (Arazia, 2016)

Perfluorinated compounds were a key ingredient in the firefighting foams used at these bases for decades. EPA data shows samples from the three townships were among the 10 highest for both perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) nationwide.

For more information on Pennsylvania PFAS contamination, The Intelligencer has an ongoing series of articles and information on the investigation.
