Where It Comes From
Production/use of PFAS-treated textiles, leather, paper/packaging, cleaners and coatings, and some firefighting foams; releases during manufacturing, use, and disposal [1][2].
How You Are Exposed
Drinking contaminated water, contact with indoor dust, some foods, and work in firefighting or PFAS-using industries [1][2].
Why It Matters
PFAS can build up in people; studies of similar PFAS report higher cholesterol, liver enzyme changes, reduced vaccine antibody response, developmental effects, and certain cancers (e.g., PFOA—kidney/testicular) [1][3][4].
Who Is at Risk
People using private wells or systems with PFAS detections, communities near PFAS manufacturing or firefighting foam use, firefighters, and pregnant people/infants [1][2].
How to Lower Your Exposure
Follow local water advisories; use home filters certified to reduce PFAS (activated carbon or reverse osmosis); limit use of stain‑/water‑repellent sprays; clean dust with a HEPA vacuum; use workplace PPE and hygiene [2][5].
