Mississauga, Ontario: Thermal Treatment at a Metal Fabricating Facility

GEO's Mississauga case study describes in-situ thermal desorption with soil vapor extraction at a former metal fabricating facility in Ontario, Canada. The contaminants listed in the source are TCA, TCE, DCA, and DCE in groundwater and saturated soil.

Installed thermal remediation equipment at the Mississauga, Ontario project.

The approximately 1,700-cubic-meter treatment volume extended to a maximum depth of 5 meters. The document describes 50 installed wells, 30 Gas Thermal Remediation heater units, and 12 soil vapor extraction wells connected to the heating installation. The target temperature was 100°C.

After 84 days, the source reports achievement of the remediation goal and a 98% reduction in groundwater contaminants. That result is a reported reduction in groundwater contamination, not a measured chemical-destruction efficiency.

Treatment-area plan for the Mississauga project.

The case study lists energy use of 99,719 kWh of electricity and 144,482 cubic meters of gas for the reported project period. It does not establish those values as a standard consumption rate for other projects.
