EPA added the Quanta Resources Corporation site in Edgewater, New Jersey (Bergen County) to the Superfund National Priorities List on September 5, 2002 because of harmful chemicals present at and near the site. For close to 100 years starting in the late 1800s, coal tar, paving and roofing materials were manufactured at the site by various entities. Quanta Resources operated at an oil processing facility there from 1974 to 1981, when the New Jersey Department of Environmental Protection closed the site after discovering large quantities of PCB-laden oil in storage tanks.
Ground water and soils at the Quanta site are contaminated with arsenic, chromium, lead and harmful chemicals, all of which can pose significant threats to human health. A plume of coal tar creosote, a thick, oily liquid used in roofing and paving that has been classified as a probable carcinogen, exists beneath the site and several adjacent properties, and extends into the Hudson River. Removal of some of the contamination by EPA addressed immediate human health threats, but recreation in and consumption of some fish from the Hudson is not recommended.
EPA began its remedial investigation/feasibility study (RI/FS) of the land portion of the Quanta site in June 2005. The presence of non-aqueous phase liquid (NAPL) coal tar, multiple historic industrial operations adjacent to the site, and several other factors prompted EPA to conduct a technical impracticability analysis as part of the evaluation of remedial measures to address contaminated groundwater. EPA concluded that the characteristics of the site make groundwater restoration technically impracticable.
In the July 2010 Proposed Plan [PDF 70 pp, 1.6 MB], EPA is proposing that contamination at the Quanta site be addressed in several ways. To address the contaminated source areas in the soil, primarily zones of NAPL coal tar and arsenic, EPA is proposing In-situ Solidification/ Stabilization of NAPL source areas and arsenic hot spots; hydraulic containment of the High Concentration Arsenic Area; capping of both the treated source areas and other areas where contaminated soils are present and to address the groundwater, EPA is proposing a Subaqueous Reactive Barrier. Portions of the NAPL are under buildings at a neighboring property, 115 River Road, the buildings would be preserved and the NAPL would be managed in place beneath them.
EPA also feels that, as a long-term strategy, the NAPL source areas under those buildings should eventually be treated. Given the age of the buildings and the value of real estate in this area, EPA expects that the current structures would be replaced at some time in the future; thus, as a additional component to the preferred alternative, EPA would require the use of ISS to address the remaining free-phase NAPL at the time when this property would be slated for redevelopment in the future.
