EPA Superfund Site

QUANTA RESOURCES

NJ | EPA ID NJD000606442

About this site’s exposure pathways: As of January 2025, the Quanta Resources Superfund site is considered “Current Human Exposure Not Under Control” (HENC). At the center of the Site is a 5.5-acre vacant lot, referred to as the Quanta property, surrounded by several developed parcels, portions of which are also considered part of the Site. In 1981, New Jersey Department of Environmental Protection (NJDEP) stopped business activities after discovering that several storage tanks at the Site contained waste oil contaminated with polychlorinated biphenyls (PCBs). Soils at the site are predominantly contaminated with polynuclear aromatic hydrocarbons (PAHs) and arsenic.

EPA issued a Record of Decision (ROD) for Operable Unit 1 (OU1) of the site in 2011. OU1 addresses contaminated soil and groundwater. The implementation of the soil remedy involving solidification and stabilization of contaminated soil on the Quanta property and adjacent properties began in 2016 and was completed in 2021. Remedial construction to stabilize contamination beneath a county road running through the site was completed in August 2024. Two additional areas need to be addressed to complete the OU1 remediation. A groundwater high concentration arsenic area to the north of the Quanta property is in the investigation stage. A component of the OU1 remedy includes the construction of a reactive barrier close to the OU2 shoreline to treat groundwater before it reaches the Hudson River. This component, known as the subaqueous reactive barrier (SRB), will be designed and implemented in coordination with the OU2 remedial action.

OU2 of the site addresses Hudson River surface water and sediments. Sediments are contaminated with arsenic, lead, PAHs, volatile organic compounds (VOCs), and non-aqueous phase liquid (NAPL). Migration of the contaminated waste oil and coal tar from the land portion of the Site, in addition to direct discharges of waste from barges into the Hudson River, has led to contamination of OU2 surface water and sediment with NAPL and PAHs. The OU2 ROD was signed in September 2024, and it is estimated that the implementation of the selected remedy can be completed in 3-4 years following the completion of the pre-design investigation and the remedial design. Until the Remedial Action is complete, the site will remain “Current Human Exposure Not Under Control.”

EPA currently anticipates that human exposure will be under control by December 2031 when the OU2 Remedial Action will be complete.

EPA ensures community participation throughout the remedial process by participating in routine quarterly Restoration Advisory Board meetings 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.
