DAVENPORT, along with our sub-consultant provided professional services necessary to assist Marine Corps Installations East – Marine Corps Base Camp Lejeune with a goal of cleaning up detected contaminated groundwater that was discovered at a construction site during the removal of an existing waterline aboard Marine Corps Base Camp Lejeune.
The extent of the impact to the groundwater was horizontally and vertically delineated, and, in an effort to clean up the impacted shallow groundwater, the remediation action was conducted through the construction of injection wells and the placement of an Oxygen Release Compound (ORC) product within the defined area of groundwater contamination. The goal of the ORC compound was to greatly enhance the natural attenuation occurring at the site. Our scope of work included activities necessary for the implementation of the remedial action plan in order to bring the levels of detected targeted compounds in the groundwater to levels below the North Carolina Groundwater Quality Standards (NCLGWQS) . At the end of the remediation activities an after action report was prepared and submitted to the proper state and federal agencies for approval.
