Per- and Polyfluoroalkyl Substances (PFAS) are a suite of over 1,000 unregulated chemicals that are widely used and can be found in various industrial and consumer products, including Aqueous Film Forming Foam (AFFF). These chemicals have been found in drinking water and groundwater supplies across the country and are of increasing interest to Congress, regulatory agencies and the public. The use of AFFF products for firefighting is the most common Marine Corps activity that could release PFAS into the environment.
