Landfills

Captain’s Cove State Superfund Site

City of Glen Cove; New York

OBJECTIVES

Roux performed an extensive multi-phased remedial investigation/feasibility study (RI/FS) and risk assessment at a former 23-acre municipal landfill. Roux focused the remediation to a six-acre portion of the Site, and subsequently implemented the selected remedial action. This Site was packaged with 75 acres of surrounding property as part of the Glen Cove Creek Revitalization Plan. The mixed-use redevelopment plan includes a hotel/convention center and a ferry terminal.

The RI/FS and risk assessment was performed to investigate:
• Soil;
• Soil gas;
• Groundwater;
• Wetlands sediment; and
• Surface water

Approximately 8,000 tons of non-hazardous, contaminated materials and 44,000 tons of bulky waste and construction and demolition (C&D) debris were transported and disposed offsite. In addition, radioactive waste was segregated and stockpiled for further management and control by the United States Environmental Protection Agency (USEPA). Since the waste material consisted largely of C&D debris and household refuse, the proposed remediation option for the buried waste was excavation, screening, and recycling instead of constructing a more costly and restrictive landfill cap. Following remedy completion, Roux implemented a long- term Operation, Maintenance, and Monitoring (OM&M) Program which included groundwater monitoring, vegetation and fence inspection, and regulatory reporting.

Additionally, Roux demonstrated that an eight-acre portion of the Site was uncontaminated, which subsequently led to the delisting of this portion of the Site from the New York State Registry of Inactive Hazardous Waste Disposal Sites. This approach significantly reduced the remediation costs and allowed unrestricted commercial water-related land use consistent with the Long Island Coastal Zone Management Plan, thus increasing the redevelopment potential and overall real estate value.
