EPA Superfund site
NEWARK SOUTH GROUND WATER PLUME
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 April 2026, the Newark South Ground Water Plume Superfund Site is considered ‘Insufficient Data to make a Human Exposure evaluation’ (HEID). The primary contaminants of concern (COCs) are volatile organic compounds (VOCs), primarily tetrachloroethene (PCE) and trichloroethene (TCE). Based on historical sampling, other VOCs, semi-volatile organic compounds (SVOCs), pesticides, polychlorinated biphenyls (PCBs), and metals are also potential COCs. The U.S. Environmental Protection Agency (EPA) has initiated the Remedial Investigation (RI) to further define the nature and extent of contamination. The City of Newark has implemented precautions to ensure the municipal water supply—historically impacted by the groundwater plume—meets state and federal Safe Drinking Water Act standards. EPA has determined that vapor intrusion is not currently a concern at the site, based on low VOC detections in the vicinity of buildings. Potential receptors include individuals who may come into contact with contaminated soil and construction workers performing excavation activities. As part of the ongoing RI, a risk assessment will be developed to support a human exposure determination. EPA anticipates completing data collection and the risk assessment by spring 2028.
