EPA Superfund site
MATTEO & SONS INC.
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 Matteo & Sons, Inc. Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID). This status does not necessarily mean that unacceptable exposures are occurring. Data are not yet sufficient to determine whether actual or reasonably anticipated human exposures are occurring above acceptable risk-based levels for Operable Unit 3 (OU3), which addresses surface water, sediment, and groundwater. Known site contaminants include lead, antimony, and polychlorinated biphenyls (PCBs) in soil and fill from historic dumping and landfilling of battery casing waste, with potential migration to nearby surface water and sediment.
Planned activities for OU3 include starting and completing a Remedial Investigation/Feasibility Study (RI/FS); collecting surface water and sediment samples in Woodbury Creek, Hessian Run, and adjacent wetlands; installing and sampling additional groundwater monitoring wells to define plume extent and migration, if any; and, if needed, collecting fish tissue and floodplain soil samples. EPA will evaluate the new data through a Human Health Risk Assessment (HHRA) that considers exposure pathways such as contact with creek and stream sediments and water, consumption of locally caught fish, and use of groundwater (including private wells), as applicable.
EPA and the New Jersey Department of Environmental Protection (NJDEP) have taken actions to reduce exposure in other parts of the site. For Operable Unit 1 (OU1), EPA issued a Record of Decision (ROD) in October 2019 to address contaminated soil on the Matteo property and along the banks of Hessian Run. The OU1 remedial design was completed in March 2023 and construction began in fall 2024. Remedial activities for OU1 are expected to be completed by October 2027. For Operable Unit 2 (OU2), a residential neighborhood in West Deptford, NJ, EPA issued a ROD in 2017 and completed excavation of impacted properties in 2022. Earlier actions included installing a chain‑link fence in 2006 to restrict access and removing approximately 425 tons of contaminated soil for off‑site disposal.
EPA currently anticipates there will be sufficient data to make a Human Exposure determination by September 2031 because the OU3 RI/FS and HHRA will be completed and the OU3 ROD will be issued by that time.
If you live or work near the site, you can reduce your exposure by avoiding contact with creek and stream sediments and water near the site, not disturbing soils on or near fenced areas, and following any posted signs or advisories. Use municipal water where available or test private wells before use. For more information, contact the EPA Community Involvement Coordinator Natalie Loney via the site webpage or at (212) 637-3639 or [email protected]. EPA will continue to engage residents and stakeholders, issue public notices and updated fact sheets, and update the site profile on EPA’s website.
