Where It Comes From
Industrial use as a processing aid/wetting agent (e.g., metal plating, coatings, firefighting foams); releases via wastewater, spills, or foam use [1][2].
How You Are Exposed
Drinking water near contaminated sites, workplace air/skin contact, household dust, and some food or packaging [1][2].
Why It Matters
Many PFAS persist in the environment; some remain in the body for years. Related PFAS are associated with higher cholesterol, liver and immune effects (reduced vaccine response), developmental effects, and, for some (e.g., PFOA), cancer [2][3][4].
Who Is at Risk
Workers handling PFAS, firefighters, people near manufacturing or AFFF sites, pregnant people, fetuses, and infants [2][4].
How to Lower Your Exposure
Check local water reports; use activated carbon or reverse‑osmosis filters certified to reduce PFAS; follow fish advisories; limit stain‑/water‑repellent treatments; follow workplace protections [1][2][5].
