What are PFAS?
What are PFAS?
PFAS are a family of human-made chemicals (including PFOS) that have been used in manufacturing and commercial products since the 1940s. Practical uses of PFAS include creating nonstick surfaces on cooking pans and food wrappers, waterproofing chemicals, foams used to fight fires, and in industries to keep fumes down for worker safety. PFAS also have been found in the environment – including groundwater (which has been used as drinking water), lakes, rivers, fish, and deer.
