EPA Superfund site
PROTECO
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 May 2026, the Proteco Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID). This status does not necessarily mean that unacceptable exposures are occurring. Proteco is a former hazardous waste landfill. Past sampling indicates groundwater contamination with mercury and volatile organic compounds (VOCs), including tetrachloroethylene (PCE) and trichloroethylene (TCE). Current information is not sufficient to determine whether actual or reasonably anticipated human exposures are occurring above acceptable risk‑based levels across all pathways and areas.
Planned activities to collect sufficient information include completing the Remedial Investigation/Feasibility Study (RI/FS); installing and sampling monitoring wells to delineate plume extent and migration, as needed; and preparing a Human Health Risk Assessment (HHRA) that evaluates potential exposure pathways such as use of private wells and other interactions with groundwater (i.e., vapor intrusion where buildings overlie the plume). EPA currently anticipates there will be sufficient data to make a Human Exposure determination by September 2029 because the RI/FS and HHRA are expected to be completed and EPA expects to select a remedy documented in a Record of Decision (ROD).
If you live or work near the site, you can reduce your exposure by using municipal water where available or testing private wells before use, allowing access for sampling if requested, and following any local health advisories. For more information, contact the EPA Community Involvement Coordinator Liliana Aleman-Roman via the site webpage or at (787) 977-5816 or [email protected]. EPA will continue to meet with residents and stakeholders, issue public notices and updated fact sheets, and keep the site profile on EPA’s website up to date.
