EPA Superfund site
BRANDYWINE DRMO
Exposure status: insufficient data
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 April 2025, Brandywine DRMO Superfund site is considered "Insufficient Data to make a Human Exposure evaluation" (HEID) because of a potential exposure pathway identified during the Five Year Review. A Vinyl Chloride (VC) plume may be within 100' of residential and commercial space, triggering a potential for Vapor Intrusion (VI) investigation. 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 levels. The planned activities to collect sufficient information to make a human exposure evaluation are a vapor intrusion investigation and assessment of nature and extent of contamination from perfluoroalkyl substances (PFAS). EPA currently anticipates that there will be sufficient data to make a Human Exposure determination by 2027. The Air Force is the lead agency at the Site and has begun the vapor intrusion investigation under EPA oversight.
