PFAS Chemicals Detected at High Levels in Malmstrom Air Force Base Groundwater

Malmstrom Air Force Base (AFB), located in Cascade County near Great Falls, Montana, has been a pivotal installation in U.S. military history since its establishment in 1942.

Originally known as Great Falls Army Air Base, it served as a training ground for bomber crews during World War II. In 1955, the base was renamed in honor of Colonel Einar Axel Malmstrom, a respected commander who tragically died in a plane crash the previous year.

Today, Malmstrom AFB is home to the 341st Missile Wing, one of three U.S. Air Force units responsible for operating and maintaining the Minuteman III intercontinental ballistic missile (ICBM) system, a critical component of the nation’s nuclear deterrent strategy.

Beyond its strategic military role, Malmstrom AFB has faced environmental challenges, particularly concerning per- and polyfluoroalkyl substances (PFAS) contamination.

Investigations conducted in 2016 and 2017 detected PFAS compounds in soil, sediment, groundwater, and surface water on and around the base.

These contaminants are primarily attributed to the historical use of aqueous film-forming foam (AFFF) in firefighting training exercises.

Recognizing the potential health risks associated with PFAS exposure, the Montana Department of Environmental Quality has designated Malmstrom AFB as a site of concern, prompting ongoing monitoring and remediation efforts to protect both the environment and public health.

Lawyers are investigating potential legal claims related to PFAS exposure at Malmstrom AFB.

If you or a loved one were exposed to PFAS chemicals at Malmstrom AFB and developed cancer or other serious health problems, you may be eligible to file a PFAS exposure claim.

Confirmed PFAS Contamination at Malmstrom AFB: Overview

Malmstrom Air Force Base (AFB) has been identified as a site of confirmed PFAS contamination, raising serious health and environmental concerns.

Confirmed PFAS Contamination at Malmstrom AFB_ Overview

According to data published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in groundwater at Malmstrom Air Force Base (AFB) in 2018:

  • PFOS (Perfluorooctanesulfonic acid): 1,900 parts per trillion (ppt)
  • PFOA (Perfluorooctanoic acid): 5,500 ppt
  • PFOS + PFOA (combined): 5,730 ppt
  • PFBS (Perfluorobutanesulfonic acid): 1,000 ppt

These concentrations significantly exceed the U.S. Environmental Protection Agency’s (EPA) 2024 Maximum Contaminant Levels (MCLs) for PFAS in drinking water, which are set at 4 ppt for both PFOS and PFOA.

The contamination is primarily linked to the historical use of aqueous film-forming foam (AFFF) for firefighting training and emergency response at the base.

This has raised concerns about potential exposure risks to service members, base personnel, and surrounding communities.

The presence of PFAS contamination at this military installation aligns with similar findings at other Air Force bases such as Cannon AFB, Sawyer AFB, and Peterson AFB, indicating a broader issue of contaminated military sites across the U.S.

With such toxic substances detected, the risks to human health, particularly through drinking contaminated water, remain a pressing concern.

Sources of PFAS Exposure at Malmstrom AFB

The primary source of PFAS exposure at Malmstrom AFB is the historical use of aqueous film forming foam (AFFF)—a fire suppression agent containing high concentrations of polyfluoroalkyl substances (PFAS).

This firefighting foam was routinely used in training simulations and actual emergencies on the base, contributing to widespread groundwater contamination and drinking water contamination.

Additional contributors include legacy waste disposal practices, maintenance activities involving PFAS containing products, and runoff from contaminated sites within the base perimeter.

As these hazardous chemicals infiltrated the water systems, both on-base drinking water and private wells in nearby communities may have been affected.

Given Malmstrom’s long-standing role as a strategic military base dating back to World War II, the persistence of PFAS compounds in the local environment underscores the urgent need to address PFAS contamination and safeguard the health of all who lived, worked, or trained at the installation.

Who May Be Exposed to PFAS at Malmstrom AFB

Individuals who served, lived, or worked at Malmstrom Air Force Base may have been exposed to PFAS chemicals through contaminated drinking water, drinking contaminated groundwater, or contact with PFAS containing firefighting foam.

This includes military service members, civilian workers, and contractors stationed at the base, as well as residents in surrounding communities who relied on local drinking water supplies.

Exposure may also have affected military personnel during training missions or while handling PFAS containing productsused for maintenance or fire suppression.

The risk extends to families of service members who resided in base housing and may have unknowingly ingested water tainted with forever chemicals.

Given the serious health consequences linked to PFAS—such as thyroid disease, kidney and testicular cancers, developmental delays, and other toxic chemical-related illnesses—those potentially exposed at Malmstrom AFB are encouraged to seek PFAS blood testing, review their medical history, and consult with legal professionals to explore their options under the Camp Lejeune Justice Act and other legal frameworks addressing contaminated military bases.

Do You Qualify for the Malmstrom Air Force Base PFAS Lawsuit?

You may qualify to participate in the Malmstrom Air Force Base PFAS lawsuit if you lived, worked, or served at the base and were exposed to PFAS-contaminated water.

This includes military personnel, civilian workers, and military service members who came into contact with drinking water contaminated by aqueous film forming foam (AFFF) or other PFAS-containing products used during firefighting and maintenance operations at the base.

Individuals who lived in nearby communities relying on private drinking water wells or drinking water supplies near Malmstrom AFB may also be eligible.

Exposure to PFAS chemicals—also known as forever chemicals—has been linked to serious health consequences, including thyroid disease, prostate cancer, testicular cancer, and other toxic chemical-related illnesses.

If you have experienced symptoms, developed cancer, or suffered other health effects believed to be caused by PFAS exposure, you may have grounds to pursue compensation under current environmental laws, including provisions related to contaminated military bases and the Camp Lejeune Justice Act.

Consulting a law firm experienced in PFAS water contamination cases can help determine your eligibility.

A legal review typically involves evaluating your time spent at military installations like Malmstrom, your medical history, and your level of exposure to hazardous substances found in PFAS-contaminated water systems.

Gathering Evidence for a PFAS Lawsuit

To support a claim in the Malmstrom Air Force Base PFAS lawsuit, gathering strong evidence of exposure and health impact is essential.

Begin by documenting your military service or employment at Malmstrom AFB, including dates of service, residence on or near the base, and your involvement with firefighting foam or other PFAS chemicals.

Veterans can request military service records, while civilians may use housing documents, utility bills, or employment records to prove proximity to the contaminated site.

Medical records showing diagnosis of PFAS-related health problems, such as kidney cancer, thyroid disease, or reproductive issues, are also crucial.

Blood testing that reveals elevated PFAS levels—such as PFOS, PFOA, or PFBS—can further strengthen your case, as can documentation of drinking water contamination from sources like the Environmental Working Group (EWG) or the Environmental Protection Agency (EPA).

Legal professionals familiar with toxic chemical exposure, PFAS contamination, and hazardous substance lawsuitscan help you gather, organize, and present the necessary documentation.

Whether your exposure came from on-base drinking water, private wells, or surrounding community water systems, timely action and proper documentation are key to pursuing justice and holding PFAS manufacturers and responsible agencies accountable.
