ORANGE VALLEY REGIONAL GROUND WATER CONTAMINATION

NJ | EPA ID NJD002148799

Exposure status: insufficient data

About this site’s exposure pathways: As of January 2025, there is insufficient information to determine the site-wide human exposure status at the Orange Valley Regional Ground Water Contamination site in the City of Orange Township, NJ, and the Township of West Orange, NJ. Samples collected indicate the presence of elevated levels of volatile organic compounds (VOCs) including tetrachloroethylene (PCE), trichloroethylene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE) in area groundwater. A Remedial Investigation/Feasibility Study (RI/FS) is currently being conducted to determine the nature and extent of contamination and completion is expected in 2026. A risk assessment will be prepared as a component of the RI to determine the site’s potential impacts to human health and the environment. EPA anticipates that upon completion of this risk assessment a sitewide human exposure determination can be made.

EPA currently ensures community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. Additionally, an EPA Community Involvement Coordinator is assigned to the site and can address specific community concerns as they arise.

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.
