PFAS Contamination Lawsuit Facts
TorHoerman Law is no longer accepting claims for the PFAS Contamination Lawsuit.
Intake Closed
Whiteman Air Force Base (AFB) in Missouri has been identified as a site of significant PFAS contamination, primarily due to the historical use of Aqueous Film Forming Foam (AFFF) in firefighting training and emergency response.
Historical use of Aqueous Film Forming Foam (AFFF), a firefighting agent extensively employed since the 1970s, is the primary source of PFAS at the base.
AFFF was commonly used in fire training exercises and to suppress petroleum-based fires, leading to the release of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) into the soil and groundwater.
The contamination has raised significant health concerns for personnel stationed at the base and residents in the surrounding areas. PFAS, often called “forever chemicals,” are linked to severe health conditions such as kidney and testicular cancer, leukemia, liver damage, and immune system disorders.
Although the base’s drinking water supply, which is drawn from a deep aquifer, has consistently tested non-detect for PFAS, groundwater sampling has revealed contamination at multiple sites.
The U.S. Air Force has implemented several measures to address the contamination.
These include a CERCLA-based environmental response, routine water monitoring, and the use of a modular mobile system to treat approximately 113,550 liters of stored contaminated water, reducing PFAS concentrations to below EPA advisory levels.
Controls have also been put in place to prevent the construction of new drinking water wells on the base and to address vapor intrusion risks in certain buildings.
Despite these efforts, the persistent nature of PFAS makes remediation complex and costly.
The base works closely with the Missouri Department of Natural Resources to manage the contamination and ensure compliance with environmental standards.
However, the long-term health implications for those exposed to high levels of PFAS at Whiteman AFB remain a serious concern, and ongoing investigations continue to assess the scope of the impact.
According to data collected by the Environmental Working Group (EWG), PFAS levels at Whiteman Air Force Base are as follows:
- PFOA (Perfluorooctanoic acid): 60,000 ppt – A widely used PFAS in firefighting foams and industrial applications, linked to kidney and testicular cancer, liver damage, and immune suppression.
- PFOS (Perfluorooctane sulfonate): 29,000 ppt – A long-chain PFAS commonly found in AFFF, associated with thyroid disease, reproductive harm, and developmental issues.
- PFOA and PFOS combined levels: 89,000 ppt – The total concentration of these two chemicals, highlighting the cumulative exposure risk to these harmful and persistent substances.
- PFHxA (Perfluorohexanoic acid): 34,000 ppt – A short-chain PFAS that is less studied but potentially linked to liver damage and developmental toxicity.
- PFNA (Perfluorononanoic acid): 6,500 ppt – A long-chain PFAS used in industrial processes, associated with increased cholesterol and developmental harm.
- PFBS (Perfluorobutane sulfonate): 7,400 ppt – A shorter-chain PFAS considered slightly less toxic than PFOA and PFOS but still linked to thyroid and kidney issues.
- PFPeA (Perfluoropentanoic acid): 7,000 ppt – A breakdown product of other PFAS chemicals, with emerging evidence of toxic effects on organs and hormonal systems.
- 6:2 FTS (6:2 Fluorotelomer sulfonate): 2,400 ppt – A newer PFAS used in modern firefighting foams, showing persistence and potential for bioaccumulation in the environment.
Who May Have Been Exposed to PFAS in Drinking Water at Whiteman AFB?
Individuals who lived, worked, or spent time at Whiteman Air Force Base (AFB) or in nearby communities may have been exposed to PFAS-contaminated drinking water.
This exposure primarily stems from groundwater contamination caused by the use of aqueous film-forming foam (AFFF) for firefighting training and emergency response on the base.
Residents who rely on private wells near the base or use unmonitored water sources may also face elevated risks.
The persistence of PFAS in the environment raises significant concerns for these groups.
Groups of people potentially exposed to PFAS at Whiteman AFB include:
- Military personnel and their families stationed at Whiteman AFB
- Civilian employees and contractors working on the base
- Residents living near the base who rely on private wells or groundwater
- Veterans who were previously stationed at Whiteman AFB
- Children and pregnant women, who are particularly vulnerable to PFAS-related health risks
- Nearby agricultural communities using contaminated water for irrigation or livestock
Whiteman AFB: Among the Hundreds of Military Sites with Dangerous PFAS Contamination
Whiteman Air Force Base (AFB) in Missouri is among numerous U.S. military installations grappling with significant contamination from per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals” due to their persistence in the environment and the human body.
The widespread use of AFFF has led to the contamination of soil and groundwater at many military sites, including Whiteman AFB.
Nationwide, the Department of Defense (DoD) has identified over 700 military sites with known or suspected PFAS contamination.
Of these, at least 455 sites have confirmed detections of PFAS in drinking water and groundwater, posing potential health risks to military personnel, their families, and surrounding communities.
Notably, some installations have reported PFAS concentrations in groundwater exceeding 100,000 parts per trillion (ppt), far surpassing the Environmental Protection Agency’s (EPA) health advisory limits.
Despite the recognition of this widespread contamination, remediation efforts have been slow.
On average, six years have elapsed between the initial suspicion of contamination and the commencement of cleanup planning at these sites.
The health implications of PFAS exposure are significant, with links to various cancers, liver damage, immune system suppression, and developmental issues.
The persistence and mobility of these chemicals in the environment complicate remediation efforts, necessitating comprehensive strategies and substantial funding to address the contamination effectively.
What is the EPA Standard for PFAS Levels in Water?
In April 2024, the U.S. Environmental Protection Agency (EPA) established the first national, legally enforceable drinking water standards for six specific per- and polyfluoroalkyl substances (PFAS).
EPA Issued PFAS Maximum Contaminant Levels (MCLs) are:
- PFOA (Perfluorooctanoic acid): 4 parts per trillion (ppt)
- PFOS (Perfluorooctane sulfonate): 4 ppt
- PFNA (Perfluorononanoic acid): 10 ppt
- PFHxS (Perfluorohexane sulfonate): 10 ppt
- HFPO-DA (commonly known as GenX Chemicals): 10 ppt
- PFBS (Perfluorobutane sulfonate): Regulated through a Hazard Index approach
The Hazard Index is a tool used to evaluate the combined risk of exposure to multiple PFAS when they co-occur in drinking water. It accounts for the additive effects of these chemicals, ensuring that the total exposure does not exceed safe levels.
These regulations aim to protect public health by reducing exposure to these persistent chemicals, which have been linked to various adverse health effects, including certain cancers, liver damage, and immune system impacts.
Public water systems are required to monitor for these PFAS and take necessary actions to comply with the established MCLs.
