Per-and polyfluorinated substances (PFAS) are a group of man-made chemicals that do not break down easily in the environment, even over a period of time. The PFAS family of chemicals include Perfluorooctane Sulfonate (PFOS) and Perfluorooctane Acid (PFOA). PFOS and PFOA are regulated by the State of California.
These compounds have been widely used in industrial applications since the 1940s including:
- Fabrics for furniture
- Paper packaging for food and other materials resistant to water, grease or stains
- Firefighting foams
- Various industrial processes
