PFAS Chemicals Detected at High Levels in McAlester Army Ammunition Plant Groundwater

McAlester Army Ammunition Plant (MCAAP), located in southeastern Oklahoma, is a major U.S. military installation responsible for producing, storing, renovating, and demilitarizing conventional munitions for the Department of Defense.

Established during World War II, the facility spans over 45,000 acres and plays a critical role in supporting military readiness through its extensive manufacturing and logistics capabilities.

Over decades of operation, the plant has conducted explosive testing, fire suppression exercises, and equipment maintenance—all activities that may have involved the use of Aqueous Film Forming Foam (AFFF).

AFFF is a fire suppressant containing per- and polyfluoroalkyl substances (PFAS), synthetic chemicals that resist heat, water, and oil but are now known to persist in the environment and accumulate in the human body.

Reports of PFAS contamination in and around military facilities nationwide have raised questions about potential environmental and health impacts at MCAAP as well.

With growing federal oversight and public concern, McAlester is now among the sites being scrutinized for possible PFAS pollution tied to historic firefighting and training practices.

If you or a loved one were exposed to PFAS contamination at McAlester Army Ammunition Plant and subsequently developed cancer or other serious health problems, you may be eligible to file a PFAS exposure claim.

Dangerous Levels of PFAS Detected at McAlester Army Ammunition Plant

Significant PFAS contamination has been confirmed at McAlester Army Ammunition Plant (MCAAP), raising alarms about the environmental and health risks to surrounding communities and military personnel.

Dangerous Levels of PFAS Detected at McAlester Army Ammunition Plant

Published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in groundwater at McAlester Army Ammunition Plant in 2020:

  • PFOS: 170,000 ppt
  • PFOA: 3,300 ppt
  • PFOS + PFOA (combined): 173,300 ppt
  • PFBS: 4,800 ppt

These concentrations significantly exceed the Environmental Protection Agency’s 2024 Maximum Contaminant Levels (MCLs) of 4 ppt for both PFOA and PFOS in drinking water, indicating serious environmental and public health concerns related to past use of firefighting foams and other PFAS-containing materials.

Sources of PFAS Exposure at McAlester Army Ammunition Plant

The primary source of PFAS exposure at McAlester Army Ammunition Plant stems from the use of aqueous film forming foam (AFFF)—a highly toxic firefighting foam used in training exercises and emergency responses to suppress jet fuel fires and chemical explosions.

As these fire fighting foams were deployed across military sites, polyfluoroalkyl substances (PFAS) leached into the soil, groundwater, and nearby water systems, leading to the toxic contamination of drinking water supplies.

Additional sources of PFAS contamination may include the improper disposal of PFAS-containing materials, hazardous substances used during manufacturing and storage, and runoff from past training exercises.

Because these synthetic chemicals do not degrade in the environment, PFAS levels continue to accumulate in both on base drinking water and private drinking water wells, threatening the health and safety of both military personnel and surrounding communities.

Who May Be Exposed to PFAS at McAlester Army Ammunition Plant

Numerous individuals may have been exposed to PFAS at McAlester Army Ammunition Plant and other military sites, including veterans, active-duty service members, civilian workers, and contractors.

Those who relied on on-base drinking water or nearby public water systems face an elevated risk of ingesting PFAS contaminated water.

In addition, residents living near the facility and using private drinking water wells may also have been unknowingly exposed to PFAS chemicals.

Because PFAS exposure has been linked to serious health problems such as thyroid disease, certain cancers(including kidney cancer), and immune system dysfunction, the impact may extend well beyond the military installation.

The presence of forever chemicals in the environment and water supply highlights the urgency of removal efforts and legal accountability under the Comprehensive Environmental Response framework and Superfund law.

Do You Qualify for the McAlester Army Ammunition Plant PFAS Lawsuit?

Individuals who lived, worked, or served at or near McAlester Army Ammunition Plant (MCAAP) and were potentially exposed to PFAS chemicals through contaminated drinking water may qualify to file a PFAS lawsuit.

Veterans exposed, military service members, civilian workers, and nearby residents who relied on private drinking water wells or on-base drinking water are among those at greatest risk.

If you have been diagnosed with a PFAS-related health condition—such as thyroid disease, certain cancers, or immune system disorders—and can demonstrate a link to your time at MCAAP, you may be eligible to pursue legal action.

PFAS lawsuits may also be available under the Pact Act, which expands protections and avenues for military personnel harmed by toxic exposure during service.

Because PFAS contamination cases are often evaluated on a case by case basis, consulting a law firm experienced in environmental and military site litigation is essential.

These claims may offer financial compensation for medical expenses, long-term care, lost income, and other damages related to PFAS exposure.

Gathering Evidence for a PFAS Lawsuit

Building a strong case for a PFAS water contamination lawsuit related to McAlester Army Ammunition Plant requires thorough documentation and clear evidence of exposure and resulting harm.

Important steps include collecting medical records showing diagnosis of PFAS-related health problems, such as kidney cancer, thyroid disease, or immune system dysfunction.

Individuals should also obtain employment records, military service documents, or residency records that prove time spent at or near MCAAP during periods of known PFAS contamination.

Additional supporting materials may include EPA testing data, evidence of PFAS concentrations in water supplies, and PFAS testing results for drinking water systems or private wells.

Legal teams may work with environmental experts to link contamination to firefighting foam (AFFF) use and other PFAS-containing products at the facility.

A qualified attorney can help determine eligibility, guide claimants through the legal process, and ensure compliance with any deadlines under the Superfund law or related environmental statutes.
