Enhanced performance monitoring of in situ thermal treatment

The clean-up of contaminated sites is economically, socially and environmentally beneficial for Canada. Many sites (brownfields) have been contaminated by hazardous liquids such as petroleum fuels, chlorinated solvents, creosote and coal tar. The clean-up of soil and groundwater at these sites can be accelerated through the application of in situ remediation technologies. In situ thermal treatment technologies are a group of aggressive remediation technologies that can be used at a variety of complex sites to meet clean-up goals over short time frames by heating soil and groundwater to water-boiling temperature and extracting the steam and vapourized contaminants. However, the performance of these technologies is difficult to measure while they are in operation due to the high temperature and high cost of operational interruption.
