EPA Superfund Site

EIELSON AIR FORCE BASE

AK | EPA ID AK1570028646

Exposure status: insufficient data

About this site’s exposure pathways: As of December 2024, the Eielson Air Force Base Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID) because per and polyfluoralkyl substances (PFAS) is present in groundwater above the EPA Safe Drinking Water Act Maximum Contaminant Level (MCL) of 4 parts per trillion (ppt) in areas with private drinking water wells. Sampling of private drinking water wells is needed to determine if the drinking water exposure pathway is complete.
EPA uses this Human Exposure status when there is a lack of evidence to suggest that actual or reasonably anticipated human exposures are occurring and that those exposures are above acceptable risk-based levels. The planned activities to collect sufficient information to evaluate PFAS are supplemental remedial investigation at the leading edge of the PFAS groundwater plume. EPA currently anticipates that there will be sufficient data to make a Human Exposure evaluation by December 2025 because United States Air Force is planning to sample the drinking water wells in 2025

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.
