Human exposure is NOT currently under control
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.

About this site's exposure pathways
As of May 2026, the Quanta Resources Superfund site is considered “Current Human Exposure Not Under Control” (HENC). Residents and recreational anglers are known or reasonably anticipated to be exposed by eating fish and shellfish caught from the Hudson River adjacent to the site and by contacting contaminated sediments and tar-like material along the shoreline. Site contaminants include polycyclic aromatic hydrocarbons (PAHs), arsenic, lead, volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), and non‑aqueous phase liquid (NAPL) in soils, groundwater, and Hudson River sediments (Operable Unit 2, OU2).
Currently, the planned activities to address pathways to human exposure include:
- Implementing the OU2 remedy (Hudson River surface water and sediments), selected in September 2024, following completion of the pre‑design investigation and remedial design (estimated 3–4 years of construction).
- Designing and constructing a subaqueous reactive barrier (SRB) near the banks of the Hudson river to treat groundwater before it reaches the river, coordinated with the OU2 remedial action construction.
- Completing remaining OU1 tasks, including investigating and addressing a high‑concentration arsenic area in soil and groundwater north of the Quanta property, maintaining completed areas of stabilized soil (Quanta property and adjacent property soil solidification completed in 2021; contamination beneath River Road stabilized in August 2024), and capping the site during redevelopment or final restoration activities.
- Working with the New Jersey Department of Environmental Protection (NJDEP) to maintain and post fish consumption advisory signage, implement institutional controls, and conduct long‑term fish tissue and sediment monitoring.
If you may be affected, you can reduce your exposure by not eating fish or shellfish caught from this reach of the Hudson River, practicing catch‑and‑release, avoiding contact with visibly contaminated sediments or tar‑like materials, and following posted signs and NJDEP advisories. For more information, contact the EPA Community Involvement Coordinator Natalie Loney via the site webpage or (212) 637-3639 or [email protected].
EPA currently anticipates that human exposure will be under control by September 2035 because the OU2 remedial action and the SRB will be completed, remaining OU1 groundwater issues will be addressed, institutional controls and advisories will be fully implemented, and long‑term monitoring is expected to show progress toward fish tissue and sediment cleanup goals, as reflected in the Superfund Enterprise Management System (SEMS).
