The Air Force will apply new Environmental Protection Agency guidance for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) to its ongoing effort to determine if water supplies at its U.S. installations and in local communities are at risk for contamination. The EPA recently released new lifetime exposure health advisories for PFOS at 70 ppt and for PFOA at 70 ppt, which the Air Force will apply. These man-made compounds, used in many industrial and consumer products, are not known to degrade naturally and persist in the environment. For more information on the Air Force's response to PFCs, visit the U.S. Air Force Civil Engineer Center webpage.
