The discovery of PFAS contamination at Hanscom Air Force Base reflects a broader issue seen at many military installations across the United States.
These toxic chemicals have infiltrated groundwater sources, putting service members, civilian workers, and surrounding communities at risk of harmful exposure.
PFAS contamination at Hanscom Air Force Base has raised significant concerns due to the high levels of these harmful chemicals found in the base’s groundwater.
Published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in Hanscom Air Force Base groundwater in 2018:
- PFOS: 44,000 ppt
- PFOA: 360 ppt
- PFOS + PFOA (combined): 44,360 ppt
- 6:2 FTS: 7,600 ppt
- 8:2 FTS: 1,000 ppt
- PFBS: 540 ppt
- PFHpA: 710 ppt
- PFHxA: 4,500 ppt
These levels far exceed the safe drinking water threshold set by the Environmental Protection Agency (EPA), highlighting the potential risks posed to both the environment and public health, particularly for individuals in and around the base.
PFAS, commonly used in firefighting foam and military training exercises, are referred to as “forever chemicals” because they persist in the environment and the human body, leading to long-term exposure risks.
Sources of PFAS Exposure at Hanscom Air Force Base
The primary sources of PFAS exposure at Hanscom AFB are believed to be related to past and ongoing military activities.
Specifically, the use of aqueous film-forming foam (AFFF) during training exercises and fire suppression operations has been linked to the contamination of both the soil and groundwater.
These chemicals can leach into local water systems, impacting nearby communities and civilian workers, as well as military personnel stationed at the base.
Who May Be Exposed to PFAS at Hanscom Air Force Base
Anyone who has had access to the contaminated water sources at Hanscom Air Force Base may be at risk of PFAS exposure.
This includes military service members, base workers, and their families living on or near the base.
Surrounding communities that rely on public or private drinking water supplies drawn from contaminated groundwater are also vulnerable.
PFAS exposure can occur through direct ingestion of contaminated water, as well as through skin contact during base activities, such as firefighting or maintenance operations.
It’s crucial to assess both on-base and off-base water supplies for potential contamination to understand the full scope of exposure risks.
