In situ bioremediation of a diesel fuel spill in northern Manitoba

Abstract

At a northern Manitoba airport, a site was contaminated with diesel fuel, which was confined within the unsaturated zone in silt and silty sand. A two-phase bioremediation process was designed and implemented in-situ in a pilot test. The first phase, ground surface spraying, involved mixing nutrients (ammonium-nitrogen and orthophosphate) with water in a tank and then spraying the mixture on the ground surface above the diesel plume. The second phase, a pump-cycle system, involved pumping groundwater from below the diesel plume into one of two tanks in series. The groundwater underwent both nutrient addition (weekly) and aeration in the tanks, then it was pumped into eight feeder wells which circumscribed an extraction well. Soil testing revealed that both remediation processes aided in increasing subsurface nutrient concentrations and the moisture content within the diesel plume. In addition, high total coliform counts were observed in both the silt and silty sand layers. This implied that conditions for suitable bioremediation can be developed in relatively fine-grained soil. Intermittent soil sampling at three locations over a 14-month period revealed that the diesel plume decreased in size by ca 30% and contaminant concentrations (diesel fuel) also decreased. Plume movement also occurred. The pump-cycle system remains  More>>
