First Environment was retained to conduct the investigation and remediation at this 15-acre site, which had become part of the New Jersey ISRA process. Located adjacent to the Delaware River, the site’s challenges included a wide range of contaminants of concern including polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs), and a variety of areas of concern including buried drums, underground storage tanks, lagoons, and landfill areas.
This complex Brownfields remediation project incorporates multiple aspects of site investigation and remediation, including U.S. Environmental Protection Agency (EPA) involvement due to the presence of PCBs above Toxic Substance Control Act (TSCA) levels, the use of self-implementing plans, complex permitting, wetland and riverfront areas, as well as a focus on long-term regional planning, and development. Based on extensive remedial investigations, First Environment determined that the site was substantially impacted with PCBs and VOCs as a result of prior operations and historic filling of the site. To address the PCB impacts, First Environment coordinated with EPA and developed a self-implementing plan to remove those soils that exceeded certain TSCA levels and restrict use of select portions of the property. The PCBs had become widely distributed as a result of the rupture of a cooling jacket surrounding a glass-lined batch reactor. Due to the release, PCBs were observed in soil adjacent to ecologically sensitive areas (i.e., wetlands and Delaware River).
First Environment personnel have been responsible for all aspects of the work plan development and implementation of soil, groundwater, surface water, sediment sampling and remediation activities, wetlands delineation, and regulatory reporting. In addition, First Environment has been responsible for all aspects of the remediation design and land use permitting. Due to the location of the site along the Delaware River, the scope of the proposed activities, and the presence of several on-site delineated wetlands and state open waters, numerous federal, state, and local land use permits were submitted and approved prior to the implementation of the remediation activities, which included the extensive removal and off-site disposal of PCB-impacted soil. We are in the process of implementing the approved remedial actions so that the site can be returned to productive use. Following the remediation activities, the site—including the wetland areas—will be restored to pre-existing conditions in order to remain protective of human health and the environment.
