Morris Air National Guard Base PFAS Lawsuit [2026 Update]

Significant levels of PFAS contamination have been identified at Morris Air National Guard Base (ANGB), which is co-located with Tucson International Airport.

Published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in groundwater at Morris Air National Guard Base (co-located with Tucson International Airport) in 2019:

• PFBS: 2,800 ppt
• PFHpA: 370 ppt
• PFHxS: 4,100 ppt
• PFNA: 5.0 ppt
• PFOA: 260 ppt
• PFOS: 4,700 ppt
• PFOS + PFOA (combined): 4,960 ppt

These concentrations significantly exceed the Environmental Protection Agency’s 2024 Maximum Contaminant Levels (MCLs) of 4 parts per trillion (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.

This data raises urgent concerns about drinking water contamination, groundwater pollution, and long-term health consequences for those exposed.

Sources of PFAS Exposure at Morris ANGB

The primary source of PFAS exposure at Morris ANGB is the historic use of aqueous film forming foam (AFFF)—a PFAS-containing firefighting foam—during military training exercises and emergency response operations.

AFFF was widely used to extinguish high-intensity jet fuel fires, a common risk at air force bases and military installations.

Over time, these toxic substances leached into surrounding soil and groundwater, leading to contaminated drinking water on and off base.

Additional PFAS pollution may have stemmed from improper disposal of PFAS-based firefighting foam, spills during equipment maintenance, and runoff into local water systems.

The use of these polyfluoroalkyl substances has created long-lasting environmental contamination with potentially dangerous implications for public health.

Who May Be Exposed to PFAS at Morris ANGB

Those most at risk of PFAS exposure include military service members, civilian workers, and contractors who were stationed at or worked near Morris ANGB when PFAS-containing firefighting foam was in use.

Families living in military housing or neighborhoods near the base that rely on private drinking water wells or are connected to off base water supplies may also be affected by PFAS-contaminated water.

The health risks linked to prolonged exposure include thyroid disease, immune system dysfunction, developmental delays, and certain cancers such as testicular and kidney cancers.

The confirmed presence of PFAS contamination at Morris ANGB and its proximity to Tucson International Airport raise serious public health and environmental concerns for the broader community and emphasize the need for continued PFAS litigation and cleanup efforts.

You may qualify for the Morris Air National Guard Base PFAS lawsuit if you lived, worked, or served at or near the base and were potentially exposed to PFAS-contaminated drinking water.

Individuals who used drinking water supplies impacted by PFAS contamination, including military service members, civilian workers, and nearby residents relying on private drinking water wells, may be eligible to file a personal injury claim or seek compensation for related health problems.

Eligibility may also apply to those diagnosed with serious conditions linked to PFAS exposure, such as thyroid disease, immune system disorders, testicular and kidney cancers, and other serious health risks.

If your exposure occurred as part of your military service or if you are a veteran exposed to PFAS chemicals during your time at a military installation, you may be entitled to benefits or damages under applicable laws, including the Camp Lejeune Justice Actand the Pact Act.

Lawsuits are evaluated on a case by case basis, so it is important to speak with a qualified law firm familiar with PFAS litigation and contaminated military sites.

Gathering Evidence for a PFAS Lawsuit

To strengthen your claim in a PFAS water contamination lawsuit, it’s essential to gather as much supporting evidence as possible.

This includes proof of residence or military service at or near Morris Air National Guard Base, medical records showing diagnoses of serious health problems, and water testing results that confirm PFAS concentrations in drinking water or groundwater contamination in your area.

Additional useful evidence includes employment records, PFAS blood test results, and documentation showing your use of on base drinking water or reliance on off base water supplies.

If available, you should also collect any communications from public health officials or the Environmental Protection Agency about confirmed PFAS contamination near your residence.

Working with a legal team experienced in PFAS lawsuits can help ensure all relevant materials are properly reviewed and used to build a compelling case against the responsible PFAS manufacturers or government agencies.
