Research

Research Interests

Transformation of organic compounds by microorganism

Several techniques exist to treat contaminated aquifers. These range from excavation and subsequent treatment of groundwater or pump and treat methods to in-situ remediation via biological or chemical transformation of hazardous materials in non-toxic compounds. Of these techniques, in-situ bioremediation has the potential to provide an efficient and cost-effective remediation procedure while minimizing site disturbance. Bioremediation is defined as the biological breakdown of organic compounds by microorganisms to non-harmful end products. To implement and monitor bioremediation a fundamental understanding of how organic compounds are transformed and which microorganisms are involved is needed. Our research is currently focused on microbial transformations of naphthenic acids, polycyclic aromatic hydrocarbons and BTEX compounds.

Research Currently in Progress

Characterization and remediation of soil and groundwater systems impacted by tailings ponds

Due to the operational necessities in the oil sands industry, out-of-pit tailings ponds are constructed to contain the tailings and process-affected (PA) water before in-pit placement can be effected. There are a number of locations on oil sands leases where the tailings ponds will be sited over buried sand channels, relict from previous glacial rivers. Preliminary modeling of these tailings ponds indicates that PA seepage will infiltrate into underlying sand channels, but the development and extent of this impact is dependent upon local geology, dyke construction, pond fluids and filling history.

The overall objectives are:

  • To understand the fate and transport of PA water through native sediments (including hydrogeologic behavior and biogeochemical transformations)
  • To explore different remediation strategies for groundwater ranging from monitored natural attenuation to in-situ chemical oxidation
