Cambridge Bay Airport Remediation – Victoria Island, NU

The Cambridge Bay Airport Apron Area and Fire Training Area (FTA) required remediation of lead-impacted materials and petroleum hydrocarbons (PHCs) relative to the historical use of fuel storage tanks and fueling related activities at the airport. Two land treatment units (LTUs) for each area were constructed over the course of three years to manage the hydrocarbon-impacted soil. 

Dillon provided site supervision on behalf of PWGSC during the remediation program. The objectives of the program included removing and disposing of a fuel transfer building containing lead-impacted materials, constructing two LTUs with surrounding monitoring wells, and the transportation of the excavated hydrocarbon-impacted material from the apron area and FTA to one of the constructed LTUs. Surface water samples were collected and analyzed for the presence of hydrocarbon impacts prior to discharging the standing water in the LTUs. During the project, perfluorinated compounds (PFCs) were identified and investigated further in the FTA.

Dillon provided construction monitoring, contract administration and implemented a quality assurance program to demonstrate that the constructed work was in accordance with the contract drawings and specifications and the intent of the design. Dillon monitored the geomembrane testing activity to make sure that testing was being carried out at the prescribed frequency and that the results were acceptable relative to the specifications.
