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.
