Groundwater Remediation Contract
Background
In 2023, the VA found liquid in the secondary containment of its fuel dispensing station. Further investigation found evidence of contamination in the surrounding soil. See Attachment A, New Hampshire Department of Environmental Services (NHDES) Spill Reporting Form and Attachment B, 2023-04-05 Environmental Conditions report. Initial sampling, NAPL Delineation, installation of groundwater monitoring wells, groundwater sampling and analysis, and creation and submission of the Remedial Action Workplan were added to the design contract of an already-funded project to replace fuel storage tanks and remove the fuel dispenser. These items are all complete and the associated documentation is attached.
Removal of the contaminated soil and installation of remediation wells was included in the construction portion of the same funded project replacing the fuel storage tanks and removing the fuel dispenser. These items are also complete. Addressing the groundwater contamination through in situ product application, follow on groundwater monitoring, and creation and submission of the Remedial Implementation Report were not included in the funded project. The purpose of this contract is to complete the remaining remediation work and required New Hampshire Department of Environmental Services (NHDES) reporting.
