Marine Corps Base Quantico has become a focal point in the growing crisis of PFAS contamination at U.S. military installations.
Recent data reveals alarmingly high concentrations of PFAS chemicals in the base’s groundwater—raising serious concerns about the long-term health and environmental consequences for military personnel, civilian workers, and nearby communities.
These toxic substances, often referred to as “forever chemicals,” do not break down in the environment and have been linked to numerous health problems.
Published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in Marine Corps Base Quantico groundwater in 2022:
- PFOS: 1,540,000 ppt
- PFOA: 374,000 ppt
- PFHxS: 372,000 ppt
- PFBS: 6,730 ppt
- PFNA: 901 ppt
- HFPO-DA (GenX): 1.7 ppt
These concentrations far exceed the EPA’s 2024 Maximum Contaminant Levels for drinking water, which are set at 4 ppt for PFOS and PFOA.
Sources of PFAS Exposure at Marine Corps Base Quantico
The contamination of PFAS detected at Marine Corps Base Quantico stems from the use of aqueous film forming foam (AFFF)—a firefighting foam widely used on military bases for suppressing jet fuel fires and conducting emergency response drills.
AFFF contains high concentrations of PFOS and PFOA, which leach into surrounding soil and water systems after repeated use over decades.
Other sources of PFAS pollution at the base likely include runoff from military training exercises, discharges from waste sites, and firefighting equipment coated with PFAS-based materials.
As with other heavily contaminated installations like Wurtsmith Air Force Base, Holloman Air Force Base, and Cannon Air Force Base, PFAS pollution at Quantico reflects systemic problems tied to military preparedness and outdated chemical use protocols that failed to account for long-term environmental and health risks.
The federal government and other agencies are attempting to remediate the significant contamination at military installations, but progress has been slow and expensive.
Who May Be Exposed to PFAS at Marine Corps Base Quantico
Those most at risk of PFAS exposure at Quantico include active-duty military personnel, civilian workers, contractors, and military families who lived or worked on the base for extended periods.
People who consumed contaminated drinking water from on-base or off-base water supplies sourced from local aquifers may have unknowingly ingested dangerous levels of PFAS over time.
Surrounding communities—especially those relying on private drinking water wells or vulnerable municipal water systems—may be affected due to groundwater migration of PFAS.
The long-term nature of PFAS contamination means that individuals exposed years or even decades ago could now be experiencing serious health risks, including thyroid disease, testicular cancer, developmental delays, and immune system dysfunction.
The full extent of exposure is still being investigated, but the presence of confirmed PFAS contamination at Quantico points to widespread risk affecting a broad population both on and near the base.
