For decades, PFAS were used in industry for firefighting foams and as a coating for waterproof, grease-proof and stain-resistant products.

PFAS exposure can happen through consuming contaminated water or food, breathing airborne PFAS, or working in occupations that use PFAS-containing products. Scientists are still determining the health effects of PFAS exposure and how they can bioaccumulate in human and animal body tissues.
