摘要

A field demonstration of Steam Stripping and Hydrous Pyrolysis Oxidation (SS/HPO) was conducted at the Portsmouth DOE facility in Ohio (PORTS). A trichloroethene (TCE) release site had DNAPL located in a semi-confined water bearing zone, and in the upper part of a shale layer. It was demonstrated that steam injection can heat the water-bearing zone directly, and that the TCE can be removed effectively, including DNAPL trapped in the top of the shale layer located below the steam zone. Both direct vaporization and removal of TCE as a vapor, and chemical oxidation contributed to reduction of the TCE source term.
