Naval Air Station Joint Reserve Base Willow Grove PFAS Lawsuit [2026 Update]

Testing conducted at Naval Air Station Joint Reserve Base (NAS JRB) Willow Grove has revealed dangerously high levels of per- and polyfluoroalkyl substances (PFAS), raising serious concerns for public health and environmental safety.

These “forever chemicals” are known for their persistence in soil and water, and at Willow Grove, they have been detected in groundwater at concentrations thousands of times above the Environmental Protection Agency’s (EPA) maximum contaminant levels (MCLs).

Measured PFAS levels at NAS JRB Willow Grove include:

• Perfluorobutanesulfonic Acid (PFBS): 15,000 ppt
• Perfluoroheptanoic Acid (PFHpA): 3,000 ppt
• Perfluorohexanesulfonic Acid (PFHxS): 61,000 ppt
• Perfluorononanoic Acid (PFNA): 68 ppt
• Perfluorooctanoic Acid (PFOA): 9,700 ppt
• Perfluorooctanesulfonic Acid (PFOS): 300,000 ppt
• Combined PFOS + PFOA: 309,700 ppt

These readings are well beyond the EPA’s 2024 drinking water standard of 4 ppt for PFOA and PFOS, highlighting the potential danger to human health and the surrounding environment.

Sources of PFAS at NAS JRB Willow Grove

The primary source of PFAS contamination at NAS JRB Willow Grove is the historical use of aqueous film forming foam (AFFF), a firefighting foam used extensively by the military to combat flammable liquid fires.

These foams contained high concentrations of PFAS compounds and were frequently used in training exercises and emergency responses.

Additional PFAS pollution may have come from maintenance activities, chemical storage, and disposal practices associated with base operations.

These hazardous substances seeped into the soil and groundwater, leading to widespread environmental contamination.

Impacted Populations at NAS JRB Willow Grove

Communities most at risk from PFAS exposure include residents near the base, former military personnel, and civilian employees who worked on site.

Many individuals in Horsham Township and surrounding areas may have been unknowingly exposed through contaminated drinking water before regulatory limits were implemented and public warnings were issued.

Vulnerable populations—such as children, pregnant women, and individuals with pre-existing health conditions—face an increased risk of developing long-term health problems including kidney and testicular cancer, thyroid disease, and immune system disorders.

Addressing PFAS Contamination at NAS JRB Willow Grove

The Department of the Navy, along with the Environmental Protection Agency (EPA) and local stakeholders like the Horsham Land Redevelopment Authority, is actively working to assess and remediate PFAS contamination at NAS JRB Willow Grove.

Ongoing efforts include groundwater sampling, public health outreach, and the implementation of interim cleanup technologies.

Despite these actions, many residents and environmental advocates argue that progress has been too slow and call for greater transparency, accelerated remediation timelines, and expanded health monitoring for those potentially affected by PFAS exposure.

Broader Implications of PFAS Contamination at NAS JRB Willow Grove

The contamination at NAS JRB Willow Grove is part of a national crisis involving PFAS pollution at hundreds of former and active military installations.

It highlights the widespread use of hazardous firefighting foams by the Department of Defense and the long-term consequences of inadequate chemical oversight.

The findings at Willow Grove emphasize the need for stronger PFAS regulations, comprehensive cleanup programs, and accountability from both federal agencies and chemical manufacturers.

As research continues to link PFAS exposure to serious health outcomes, cases like this serve as a wake-up call for better protection of public health and natural resources across the country.

PFAS, or per- and polyfluoroalkyl substances, are a class of synthetic chemicals developed for their resistance to heat, water, and oil.

These manufactured chemicals have been used in a wide range of consumer and industrial products since the 1940s, including firefighting foams, nonstick cookware, food packaging, and stain-resistant fabrics.

Commonly called “forever chemicals,” PFAS are extremely persistent in the environment and the human body — meaning they do not break down and can accumulate over time.

Their widespread use, combined with their resistance to natural degradation, makes PFAS chemicals a growing concern for environmental and public health authorities.

Why Are PFAS Chemicals Dangerous?

PFAS chemicals are dangerous because of their ability to remain in the environment and in human tissue for years — even decades — after initial exposure.

These compounds can accumulate in the blood, liver, and other organs, disrupting normal biological functions.

Even at low concentrations, PFAS have been linked to harmful health effects, and once they enter the body, they are extremely difficult to eliminate.

Their resistance to natural breakdown processes and their tendency to contaminate water, soil, and food chains make them particularly hazardous substances requiring close regulation and cleanup.

Health Risks Associated with PFAS Exposure

Scientific research and data from the Environmental Protection Agency (EPA) and National Institutes of Health (NIH) have linked PFAS exposure to a range of serious health issues.

Known risks include:

• Kidney and testicular cancer
• Thyroid disease and hormone disruption
• Elevated cholesterol levels
• Immune system suppression
• Reproductive issues, including pregnancy-induced hypertension and low birth weight
• Liver damage and changes in liver enzymes

These health effects are especially concerning for vulnerable populations such as children, pregnant individuals, and people with preexisting health conditions.

Long-term PFAS exposure through drinking water, contaminated soil, or food can increase the likelihood of developing chronic illnesses over time.

Environmental Impact of PFAS

PFAS contamination poses a serious and lasting threat to the environment.

These chemicals seep into soil and groundwater, spreading far from their original source and remaining detectable for decades.

PFAS are resistant to traditional water treatment methods, which makes their removal from public drinking water systems particularly challenging.

Wildlife exposed to PFAS-contaminated environments can suffer reproductive harm, developmental delays, and organ damage.

At military sites like NAS JRB Willow Grove, PFAS contamination from firefighting foam has impacted local ecosystems and continues to threaten surrounding communities and water supplies.

Why Urgent Action is Needed

PFAS contamination is a growing national crisis that requires immediate attention from lawmakers, regulators, and communities.

Without urgent intervention, PFAS will continue to accumulate in the environment and human bodies, compounding the risk of serious health outcomes and long-term ecological damage.

While the EPA has introduced stricter drinking water standards for certain PFAS compounds, more work is needed to accelerate cleanup efforts, hold polluters accountable, and fund medical monitoring for impacted populations.

Communities like those around NAS JRB Willow Grove are counting on swift, transparent action to reduce exposure, clean up contaminated sites, and prevent future harm from these toxic substances.

You may qualify for the NAS JRB Willow Grove PFAS lawsuit if you lived, worked, or served at or near the base and were exposed to contaminated drinking water or groundwater containing hazardous PFAS chemicals.

Individuals who relied on public or private water supplies in the Horsham area and later developed health conditions such as kidney cancer, thyroid disease, immune disorders, or other PFAS-related illnesses may be eligible to file a claim.

Legal action may also be appropriate if property you own was affected by PFAS contamination, leading to reduced value or other damages.

Speaking with an attorney can help determine your eligibility based on your exposure history, location, and medical background.

Gathering Evidence for a PFAS Lawsuit

Building a strong PFAS lawsuit requires detailed documentation that links your exposure at NAS JRB Willow Grove to specific health effects or property damage.
