Williams Air Force Base PFAS Lawsuit [2025 Update]

Dangerous Levels of PFAS Contamination Detected at Williams Air Force Base

Williams Air Force Base, once a leading pilot training facility in Arizona, has been identified as a site of significant PFAS contamination, raising concerns for the health of military personnel, civilian workers, and surrounding communities.

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

• PFOA: 489 ppt
• PFOS: 2,440 ppt
• PFOA + PFOS (combined): 2,929 ppt

These levels significantly exceed the Environmental Protection Agency’s (EPA) 2024 Maximum Contaminant Level (MCL) of 4 parts per trillion (ppt) for both PFOA and PFOS in drinking water.

The base’s history of fighter gunnery training, aircraft operations, and technical training programs likely contributed to widespread contamination of drinking water sources and soil.

As a former hub for military training missions, including radar observer training, night fighter training, and twin engine flying skills, the site used large quantities of aqueous film forming foam (AFFF) containing PFAS chemicals that have now leached into the groundwater and nearby water supplies.

Sources of PFAS Exposure at Williams Air Force Base

The primary source of PFAS exposure at Williams Air Force Base is the long-term use of aqueous film forming foam (AFFF) — a fire suppressant used in jet fuel fires, aircraft crash drills, and fuel spill cleanups.

These PFAS-containing products were routinely deployed during training exercises, aircraft maintenance, and base emergency operations.

PFAS contamination was also likely exacerbated by improper waste disposal and runoff from storage areas and airfields used during flexible gunnery training and air corps conducted drills.

In addition to AFFF, exposure could have occurred through contact with contaminated drinking water, ingestion of PFAS-contaminated groundwater, or use of toxic substances in flight training, engine repair, and aircraft decontamination procedures.

The military base’s infrastructure, including water systems and firefighting facilities, may still harbor hazardous chemicals, creating an ongoing risk to public health and the environment.

These sources of exposure demand greater attention to PFAS testing, remediation efforts, and long-term health monitoring for impacted individuals.

Who May Be Exposed to PFAS at Williams Air Force Base

Individuals potentially exposed to PFAS at Williams Air Force Base include a wide range of people who lived, trained, or worked at the facility between its years of operation and its closure.

This includes military service members, flight instructors, civilian contractors, and support staff involved in pilot training programs, fighter gunnery schools, and other military training missions.

Families living on base or in nearby residential areas may have consumed contaminated drinking water, inhaled airborne particles, or come into contact with PFAS-contaminated soil during everyday activities.

Given the documented confirmed PFAS contamination, both on base and in surrounding groundwater, the risk of developing serious health problems such as thyroid disease, kidney cancer, prostate cancer, and other immune system disorders is elevated.

The EPA, Department of Defense, and environmental health experts are continuing to study the health risks associated with PFAS exposure, but many believe that individuals exposed at Williams AFB could face long-term health consequences.

These exposed populations may be eligible to participate in PFAS water contamination lawsuits and should consider undergoing a PFAS blood test and speaking with a law firm experienced in military toxic exposure cases.

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

Individuals who lived, worked, or served at Williams Air Force Base—or who were otherwise exposed to PFAS-contaminated drinking water at or near the site—may qualify to take legal action through a PFAS water contamination lawsuit.

This includes military service members, civilian employees, contractors, and family members who used or consumed water from affected water systems.

If you’ve experienced serious health problems potentially linked to PFAS exposure, such as thyroid disease, kidney cancer, prostate cancer, or immune system disorders, you may be eligible to file a claim.

The base’s past use of aqueous film forming foam (AFFF) containing toxic PFAS chemicals is a key contributor to widespread groundwater contamination, impacting both on-base drinking water and nearby water supplies.

Consulting a law firm familiar with PFAS litigation and military toxic exposure can help you determine your eligibility.

Gathering Evidence for a PFAS Lawsuit

To build a strong case in a Williams Air Force Base PFAS lawsuit, it’s important to gather detailed evidence showing both exposure and resulting health effects.

Relevant evidence may include medical records showing diagnosis of illnesses such as cancer, thyroid disease, or developmental delays, as well as proof of residency, employment, or military service at or near the contaminated military site.

Test results from a PFAS blood test, data showing PFAS concentrations in your water supply, and documents detailing your proximity to confirmed PFAS contamination can all support your claim.

Additional helpful information includes records of time spent at training facilities, airfields, or locations where firefighting foam was used.

An experienced legal team can assist with identifying qualifying evidence and navigating claims under the Camp Lejeune Justice Act, Superfund law, or other applicable statutes.
