Per- and polyfluoroalkyl substances (PFAS) are a large family of man-made chemicals that contain carbon, fluorine, and other elements. These chemicals have been in use since the 1940s and are found in a variety of products including firefighting foams, household products such as non-stick cookware, food packaging, and stain and water repellants.
