Where It Comes From
Made for water‑ and stain‑resistant applications and industrial surfactants; PFAS like this have been used in metal‑plating mist suppressants and some foams [1][2].
How You Are Exposed
Drinking water near manufacturing, plating, or waste sites; eating contaminated fish/food; indoor dust; and workplace contact in plating, coatings, or firefighting [1][2].
Why It Matters
PFAS persist and can build up in people. Some are linked to higher cholesterol, reduced vaccine response, liver changes, pregnancy complications, and certain cancers (e.g., PFOA) [1][3][5].
Who Is at Risk
Workers handling PFAS, firefighters using AFFF, residents on contaminated private wells, pregnant people, infants, and communities near PFAS facilities [1][2].
How to Lower Your Exposure
Test well water; use filters certified to reduce PFAS (NSF/ANSI 53 or 58); follow fish advisories; damp‑dust/vacuum with HEPA; follow workplace protections [1][4].
