PFAS are a group of manufactured chemicals that have been used in industry and consumer products since the 1940s. One common characteristic of concern of PFAS is that many break down very slowly and can build up in people, animals, and the environment over time. PFAS are used in in aqueous film-forming foams (or AFFFs) used to extinguish flammable liquid-based fires. Such foams are used in training and emergency response events at airports, shipyards, military bases, firefighting training facilities, chemical plants, and refineries. (Source: EPA)
