A recent environmental investigation at the Dover Air Force Base revealed the presence of a contaminant found in foam that’s used to control fires.
The investigation found levels of perfluorinated compounds, PFCs, above EPA limits at four locations at the Dover Air Force Base. While PFC’s were detected in shallow groundwater and some surface drainage ditches, none were found in the drinking well water. The Dover Air Force Base derives its drinking water from a deep underground aquifer that’s isolated from the aquifer where the PFCs were found.
PFCs are man-made chemicals found in heat-resistant and water-repellant objects. They are also present in the foam that’s used by the Air Force Base to fight fires. In 2009, the EPA issued two health advisories for two of the compounds. PFCs have not been directly linked to adverse health outcomes in humans, but they have been identified as a likely carcinogen.
The Air Force Base will continue to inspect remaining locations on-site for the chemicals later this year. The results from the recent investigation are currently online.
