The application of both bioremediation and a barrier system for contaminant remediation is being investigated for implementation at Resolution Island, Nunavut. Preliminary investigations include an environmental assessment, contaminant delineation, and hydrocarbon characterization. The project will include an investigative approach to employing the Canada-Wide Standards for Petroleum Hydrocarbons in soil (not previously applied to Nunavut and the Canadian Arctic) and ultimately a recommendation for the environmental cleanup. Prospective solutions include landfarming (bioremediation and aeration) and barrier construction. Experimental design will consider such items as the chemical properties of the hydrocarbon contaminant and character of the diesel spill, geographic location, history, geology and climate. Landfarming trials will be conducted on site and laboratory studies will complement these and include an molecular investigation and characterization. For the barrier work various options are available to remediate the contamination by the use of geosynthetics, filters and ponding. Again there will be a field and laboratory component to this research.
