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.

About this site's exposure pathways

As of September 2026, the Wright-Patterson Air Force Base Superfund site is considered “Current Human Exposure Not Under Control” (HENC) because per- and polyfluoroalkyl substances (PFAS) occur in groundwater used to supply the Area B public water systems at concentrations above the Maximum Contaminant Levels (MCLs). Based on Unregulated Contaminant Monitoring Rule (UCMR) 5 data, PFAS-contaminated groundwater is being used as source water, creating an unacceptable drinking water exposure pathway for nearby users because concentrations exceed MCLs. EPA currently anticipates that human exposure will be under control by April 2029 because the Air Force will continue monitoring and install treatment to reduce PFAS concentrations in the affected water systems. EPA recommends that affected residents contact their water provider, follow drinking water advisories, attend Restoration Advisory Board meetings, and contact the Air Force for more information.
