Abstract
The effect of spatial variations in the pneumatic permeability on soil vapor extraction (SVE) cleanup times is explored. Several ways for generating families of permeability functions are discussed, and the characteristics of the resulting functions are examined. The results of eight data sets of 10 runs each are presented. Rather substantial variations in cleanup time are found even for runs using permeability functions drawn from the same family. Rate of cleanup correlates somewhat with average permeability, but this correlation leaves a good deal of variation in cleanup time unaccounted for. It is hoped that this work will give a clearer understanding of the uncertainties intrinsic in the modeling of SVE.Keywords
