Army Polyfluoroalkyl Substances (PFAS)

The Army Addresses PFOS/PFOA

Map: Sampling Results with PFOS/PFOA Exceedances at Army Installations

In August 2016, the Army proactively implemented a comprehensive PFOS/PFOA approach to manage risk to Army Soldiers, Families, and Civilians from PFOS/PFOA in drinking water.

The Army is reviewing inventory of potential PFOS/PFOA source areas such as areas where AFFF was stored or used (e.g. fire training areas, aviation assets, PFOS/PFOA mist suppressant use).  The Army is planning and requested funding to replace AFFF in first responder vehicles in 2019 with C6 PFAS AFFF formulations that have been identified in the DoD AFFF MILSPEC.

The Army has initiated Comprehensive Environmental Response Compensation and Liability Act (CERCLA) Preliminary Assessments (PAs) and where the results of the PAs indicate that a release may have occurred, the Army will initiate Site Inspections to determine whether additional action is needed.

In November 2017, the Army completed its PFOS/PFOA water sampling at 2,905 Army locations including 380 Army drinking water systems, both inside and outside the United States.  These drinking water samples were analyzed at commercial environmental laboratories using EPA Method 537 (industry standard analysis) and indicated 12 Army locations where the LHA had been exceeded.

PFOS/PFOA LHA exceedances at these Army installations/locations have been mitigated. If PFOS/ PFOA concentrations exceed the LHA, the Army will continue to perform appropriate mitigation through a variety of methods such as providing:   

Bottled water, water filtration system, municipal water supply hookup, blended water
