Semianalytical Simulation of Soil Vapor Extraction

Abstract
Soil vapor extraction (SVE) is a proven effective in situ technology for the removal of volatile organic compounds (VOCs) from the subsurface. However, most systems designed to date are based on empirical methods, rules-of-thumb, or results obtained from time-consuming and expensive pilot-scale field tests. Thus, it is very difficult to extrapolate laboratory results to field applications, to test hypotheses, to evaluate different subsurface scenarios, to accumulate experience, to optimize operation parameters, to predict field performance, and to modify operation parameters in response to unanticipated subsurface conditions. In this paper, the development of a three-dimensional semianalytical model for the simulation of transport and fate of VOCs in the subsurface during a multiple-well soil vapor extraction operation is presented. The model provides the necessary but simple-to-use engineering design tools for the process. Illustrative examples on the use of the model developed are also presented.
