What are PFOS/PFOA?

Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) are part of a man-made class of chemicals called Perfluorinated compounds (PFCs). These chemicals are long lasting in the environment and have been used since the 1950s in many products  because of their stain and water repellant properties and have been present in regular household items such as fabric for upholstered furniture, carpets, nonstick cookware, and floor wax amongst other items. PFOS/PFOA have been globally distributed in the environment and have been detected in the blood of humans, wildlife, and fish.

PFOS/PFOA are Unregulated Contaminants. There are no Safe Drinking Water Act regulatory limits for the use of PFOS/PFOA. The United States Environmental Protection Agency uses the "Unregulated Contaminant Monitoring Rule" program to collect data for emerging contaminants suspected to be present in drinking water.
