EIELSON AIR FORCE BASE
Human exposure is NOT currently under control
Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data. It is not affiliated with or endorsed by EPA, and is not a substitute for a professional environmental assessment.
About this site's exposure pathways
As of July 2026, the Eielson Air Force Base Superfund site is considered ‘Current Human Exposure Not Under Control’ (HENC). Per and polyfluoroalkyl substances (PFAS) is present in groundwater above the EPA Safe Drinking Water Act Maximum Contaminant Level (MCL) of 4 parts per trillion (ppt) for PFOS and PFOA in areas with private drinking water wells. North Pole residents in the plume have not been supplied alternate water. The Air Force will not sample private wells in North Pole until 2028, however, Air Force has been sampling monitoring wells in North Pole since at least 2015. The Air Force publishes an Annual PFAS Groundwater Monitoring Report. The 2025 report indicates PFOS and PFOA exceedances in the same aquifer as the private drinking water wells (confirmed by Air Force boring logs and publicly available private well logs). Residents have had their own wells sampled, confirming the presence of PFOS and PFOA above MCL.
