PCB-Contaminated Site Remediation

Coneco has provided Licensed Site Professional (LSP) services at an electrical substation located in Malden, Massachusetts. Coneco personnel collected a sample from a soil stockpile generated during the construction of an exterior stair enclosure at the Site in order to determine the proper disposal method for the soil. Laboratory analysis identified concentrations of PCBs in the soil sample in excess of the applicable Department of Environmental Protection (DEP) Reportable Concentrations. Following the removal and proper off-Site disposal of the soil stockpile, Coneco personnel directed assessment activities at the Site in order to characterize and delineate the potential source area(s) of the identified PCB concentrations. Assessment activities identified three distinct areas of concern at the Site which required remediation under applicable state and/or federal regulations. Coneco subsequently directed Release Abatement Measure and Performance-Based Disposal activities in accordance with MCP and TSCA regulations which were successful in remediating the elevated concentrations of PCBs in soil at the Site to levels which do not pose significant risk to health, safety, public welfare, and the environment.
