CLEANUP ACTIONS

The Army follows the federal cleanup law, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 (also known as “Superfund”), and long-standing Environmental Protection Agency (EPA) regulations for all chemicals in its cleanup program, including PFAS.  In collaboration with federal and state regulatory agencies and interested stakeholders, the Army follows the CERCLA process to investigate a release resulting from Army activities and to assess the appropriate cleanup actions based on risk to human health and the environment.

When the Army identifies that it has impacted drinking water above 70 parts per trillion for PFOS/PFOA on or off an installation, it takes appropriate actions to provide alternate water and ensure drinking water levels are promptly reduced below the health advisory levels (for example, by providing bottled water, shutting down wells, installing treatment systems or connecting to municipal water).

Final reports, points of contact, and/or site specific web links will be updated on this page as cleanup actions progress.

CERCLA is a complex, multi-phase process that provides a consistent, science-based approach across the nation for cleanup and may take years to complete. Read more about CERCLA and the phased approach here
