EPA Superfund site
DELTA SHIPYARD
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 August 2025, the Delta Shipyard Superfund Site is considered "Insufficient Data to make a Human Exposure evaluation" (HEID). A second round of sampling to assess the extent of contamination was completed in August 2021. The human health risk assessment started in 2024 and is scheduled to be completed by November 2025, with the Remedial Investigation expected to be completed by May 2026. At that time, it is anticipated that sufficient information will be available to make a Human Exposure status determination.
