Per- and Polyfluoroalkyl Substances (PFAS) in Missouri - PUB2803

Nothing in this document may be used to implement any enforcement action or levy any penalty unless promulgated by rule under chapter 536 or authorized by statute.

Per- and Polyfluoroalkyl Substances (PFAS) are a group of manmade fluorinated chemicals that have been used in industry and consumer products since the 1940s because of their ability to repel both water and oil. These chemicals can be found in products such as non-stick cookware, carpet, clothing, furniture fabrics, waxes, cleaning products, some firefighting foams and in industrial applications. Many PFAS break down very slowly and can build up in people, animals and the environment over time.
