Per- and Polyfluoroalkyl Substances (PFAS)

Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals used to make household products stain-resistant, waterproof and nonstick. PFAS are found in many products like carpet, upholstery, cookware, food packaging and fire-fighting foam. Although many U.S. companies have stopped using certain PFAS chemicals, they are still commonly used in foreign products imported and sold in this country.
