Specific Research Interests and Activities:
- Environmental fate of organic contaminants in porous and fractured subsurface systems.
- Characterization of non-aqueous phase liquid (NAPL) source zones in fractured subsurface systems.
- Transport and fate (survival) of colloidal and biocolloid constituents in fractured subsurface systems.
- Development and assessment of source zone remediation technologies.
The input, transport and fate of contaminants in groundwater
systems are of particular importance in Canada given that more than
25% of Canadians depend on groundwater for their domestic water
supply. My research goals focus on the characterization, transport
mechanisms, fate and treatment of both chemical and biological contaminants
in groundwater. My research approach creates linkages amongst science,
mathematics and engineering through physical experimentation and
mathematical modeling. Our research facility includes state-of-the-art
visualization and analytical techniques, as well as high-power computers.
