EAST BASIN ROAD GROUNDWATER

DE | EPA ID DEN000304044

Exposure status: insufficient data

About this site’s exposure pathways: As of May 2025, there is insufficient information to determine Sitewide Human Exposure Control status at the East Basin Road Groundwater Superfund Site (Site). The Site was finalized on the National Priorities List (NPL) on March 29, 2023, and there has been no evaluation of the human health exposure indicator yet. This does not necessarily mean that unacceptable exposures are occurring. The potentially responsible party (PRP) search to identify liable parties to perform remedial investigation/feasibility study (RI/FS) activities is ongoing, and the EPA anticipates identifying some parties to begin RI/FS work by the end of 2026. The EPA is also planning to assess vapor intrusion starting in the spring of 2025 and implement mitigation measures, if needed.

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.
