PFOS/PFOA Resources

Perfluorinated compounds, or PFCs, are a group of man made chemicals used for a wide variety of residential, commercial and industrial purposes including: nonstick cookware, stain-resistant fabric and carpet, some food packaging and firefighting foam.  Recently throughout the United States, these chemicals have been detected in drinking water supplies. 

In 2016 the Environmental Protection Agency established health advisory levels in drinking water for two types of PFCs - perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). PFOS and PFOA are classified as emerging contaminants because they do not have established regulatory standards, but evolving science has identified potential risk to humans and regulatory standards are under consideration.
