Pennsylvania faces extensive PFAS contamination from military installations and the state's long industrial history. Naval Air Station Joint Reserve Base Willow Grove has created significant contamination affecting southeastern Pennsylvania communities and threatening the Delaware River watershed. The former Naval Air Warfare Center in Warminster has additional extensive contamination affecting Montgomery and Bucks County water supplies.

Pennsylvania's chemical industry legacy, including DuPont facilities and other major manufacturers, has created numerous PFAS sources throughout the state. The Delaware River, which provides drinking water to millions of people in Pennsylvania, New Jersey, and New York, requires enhanced monitoring and protection. Philadelphia International Airport and Pittsburgh International Airport have contributed additional contamination through AFFF use.
