Army Polyfluoroalkyl Substances (PFAS)

Army PFAS Data

The Army is committed to protecting human health and ensuring the supply of safe drinking water to its Soldiers, Family Members, and Civilians. As part of this commitment, we will continue our comprehensive efforts to investigate, mitigate, and clean up Army releases of certain per and poly-fluoroalkyl substances (PFAS) as appropriate to ensure continued protection of human health.


While Environmental Protection Agency (EPA) has not issued a Maximum Contaminant Level for perfluorooctane sulfonate and perfluorooctanoic acid (PFOS/PFOA) in drinking water, the Army has proactively tested its drinking water systems and mitigated where PFOS/PFOA levels were above the EPA’s non-regulatory, Lifetime Health Advisory (LHA) of 70 parts per trillion (ppt). PFOS/PFOA are the two most studied PFAS compounds. There are currently no Army personnel or families drinking water with levels of PFOS/PFOA above the LHA. The Army will continue its efforts to appropriately address areas that may have been impacted by PFOS/PFOA, and will periodically post information related to such efforts on this web site.
