PFAS chemicals, widely known as “forever chemicals” due to their persistent nature in the environment and human body, have been detected at alarming levels in the groundwater at the former Chanute Air Force Base.
Published by the Environmental Working Group (EWG), PFAS chemicals were detected at the following levels in Chanute AFB groundwater in 2018:
- PFOS: 496,000 ppt
- PFOA: 148,000 ppt
- PFOA + PFOS: 644,000 ppt
- PFHxS (Perfluorohexanesulfonic Acid): 806,000 ppt
- PFBS (Perfluorobutanesulfonic Acid): 80,700 ppt
- PFHpA (Perfluoroheptanoic Acid): 35,100 ppt
- PFHxA (Perfluorohexanoic Acid): 7,300 ppt
- PFNA (Perfluorononanoic Acid): 3,250 ppt
- NEtFOSAA (N-Ethyl perfluorooctanesulfonamidoacetic acid): 320 ppt
- NMeFOSAA (N-Methyl perfluorooctanesulfonamidoacetic acid): 320 ppt
- PFDA (Perfluorodecanoic Acid): 130 ppt
- PFDoA (Perfluorododecanoic Acid): 130 ppt
- PFTrDA (Perfluorotridecanoic Acid): 130 ppt
- PFUnA (Perfluoroundecanoic Acid): 130 ppt
These concentrations far exceed the Environmental Protection Agency’s (EPA) recommended limits for PFAS levels in drinking water, which are set at 4 parts per trillion (ppt).
The dangerously high levels of these toxic chemicals in the groundwater at the former Chanute AFB raise serious concerns about the long-term health risks to individuals who were exposed to contaminated water at or near the base.
Sources of PFAS Exposure at Chanute AFB
PFAS exposure at Chanute AFB primarily originates from the historical use of Aqueous Film-Forming Foam (AFFF), which is used in firefighting activities, particularly for jet fuel fires and training exercises.
AFFF has contaminated both groundwater and surrounding water sources at the site.
The presence of these per and polyfluoroalkyl substances (PFAS) has posed a significant environmental and health risk to those who lived and worked at the base, as well as residents in nearby areas who relied on private drinking water wells and public water systems.
Hazardous substances from military operations, including other industrial chemicals, may have contributed to PFAS contamination in soil and surface water on and around the base.
Who May Be Exposed to PFAS at Chanute AFB
Individuals who may have been exposed to PFAS at Chanute Air Force Base include military personnel stationed at the base, as well as civilian workers employed there during its operational years.
Residents of nearby communities who relied on private drinking water wells or local public water systems may have also been at risk.
Exposures could have occurred through contaminated drinking water, as well as through airborne exposure during firefighting training or proximity to jet fuel fires.
People who lived on or near the base during its operation, particularly before PFAS contamination was fully recognized, may have been exposed to high concentrations of these toxic chemicals.
Family members of military service members and other individuals who frequented the base, such as contractors and visitors, could have been indirectly exposed to the dangerous levels of PFAS chemicals present at Chanute AFB, potentially leading to a range of health problems.
