DRINKING WATER

The Army is committed to ensuring quality drinking water is provided to its Soldiers, family members, and DoD civilian workforce. The Army and other purveyors (e.g. Privatized water system partners) perform proactive sampling on its drinking water systems for PFOS and/or PFOA IAW Army Policy.

On April 26, 2024, the EPA published a final federal National Primary Drinking Water Regulation (NPDWR) establishing drinking water standards for certain PFAS under the Safe Drinking Water Act (SDWA). This rule applies to public drinking water systems and includes enforceable Maximum Contaminant Level (MCL) to include 4 ppt for PFOS and 4 ppt for PFOA. The rule provides five years for regulated public water systems to comply. The Army continues to collect necessary sampling information and is taking actions to ensure compliance with the required 5-year timeframe. For the latest Drinking Water sampling results, please see the OSD PFAS On-base drinking water database https://www.acq.osd.mil/eie/eer/ecc/pfas/data/onbase-drinking-water.html

Status: Finished drinking water, which is the treated water people drink at the Presidio of Monterrey, is purchased by the Army. Water testing for PFOS/PFOA can be performed by either the drinking water provider or the Army.

Type of drinking water systems: Army-owned, privatized and purchased

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 the EPA’s 2016 lifetime health advisory levels 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
