EPA Superfund Site

CURTIS BAY COAST GUARD YARD

MD | EPA ID MD4690307844

Exposure status: insufficient data

About this site’s exposure pathways: As of April 2025, the Curtis Bay Coast Guard Yard Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID). Following a significant storm event, potentially contaminated landfill material at the Grove site was identified at or near the surface of an area which is used for recreation (boat ramp).

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 additional per- and polyfluoroalkyl substances (PFAS) soil sampling and evaluation of the Grove Site Remedial Investigation data and PFAS data. EPA anticipates that there will be sufficient PFAS data to make a Human Exposure determination by the end of September 2025. The Grove Site investigation is underway and contaminants of concern have not yet been identified.

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.
