Installation Restoration Program – Fort Drum, NY

SERES, as part of the SERES-Arcadis Joint Venture, was awarded two continuous contracts for environmental remediation, monitoring, and Operations & Maintenance (O&M) services to support the Fort Drum Installation Restoration Program (IRP). This IRP includes six petroleum spill remediation sites affecting more than 66 acres and 414 million gallons of groundwater; a New York State Department of Environmental Conservation Class 2 Inactive Hazardous Waste Site; and two closed unlined landfills impacted by petroleum-based volatile organic compounds, chlorinated volatile organic compounds, per- and polyfluoroalkyl substances (PFAS), and metals. The team achieved several key project successes in multiple CERCLA phases including:

• Site closure at three sites within the first contract from 2020-2024.

• Remedial Action Operation: O&M of a green remediation-based thermal in-situ remediation system that uses both solar heating and waste heat from remediation system equipment to promote biological degradation of petroleum in-situ – greatly increasing the rate of remediation. This system achieved shut-down criteria at one of the sites within 1.5 years of operation, which was less time than initially predicted at the onset of remedial activities.

• Landfill O&M and Long-Term Monitoring: Implemented and optimized a base-wide groundwater monitoring program that includes spring and fall groundwater monitoring and reporting, maintenance of two closed landfills, and land use control inspections. The team successfully reduced the sampling and maintenance scope through the implementation of sampling optimization strategies, no-purge sampling methods, and proactive requests for monitoring well abandonments.
