PFCs have been found at public and private drinking water wells near the Former Naval Air Station Joint Reserve Base in Willow Grove and former Naval Air Warfare Center in Warminster. During the information sessions, officials are expected to give an update on actions taken to address the issue.

PFOS are perfluorinated compounds that are or were once used in a variety of consumer products, such as fire-fighting foam, stain and water repellants, paper products, the lining of microwave popcorn bags, floor wax and non-stick cookware. In laboratory animals, PFOS can cause developmental, reproductive and other adverse effects, according to the Horsham Water and Sewer Authority.
