Abstract
The effectiveness of a thermally enhanced soil vapor extraction (SVE) system to remove semi-volatile organic chemicals (SVOCs) was investigated in a field study. The data allowed the calculations of SVOC removal rates at several temperatures. A previous laboratory study using the same field soils had developed a relationship between SVOC removal rate constants and inverse temperature. The laboratory and the field SVOC removal rate constants were compared and a linear log–log relationship between the laboratory and the field SVOC removal rate constants resulted. Subsequent analyses indicated that it was possible to use laboratory determined SVOC removal rate relationships to estimate SVOC removal from in situ field soil. The time dependence of SVOC concentration reduction using in situ thermally enhanced SVE systems was also shown.
