摘要

Contaminated groundwater is a widespread problem often requiring innovative technology tornremediate. The purpose of this paper is to present the laboratory results of air sparging models. Initial testsrnused very fine porous media (glass beads-packed column) to represent a relatively homogeneous soil samples.rnSubsequent testing employed budded core samples taken from a site of interest to represent more realistic,rnheterogeneous samples. 1,1,1 Trichloroethane (TCA) was used as the dissolved contaminant to represent BTEX/rngasoline contamination; however, results obtained here can be applied to any NAPL-dissolved phase. Arntechnique based on foam injection is proposed and is demonstrated to reduce air mobility. This reduction in airrnmobility has potential to improve contaminant removal. Laboratory results are compared with predictions of arnnumerical model, which is an advection-diffusion air sparge simulation model. Sensitivity analysis of thernnumerical model provides the range of some key parameters used to screen/evaluate air sparging as thernremediation method for a given contaminated site of interest. Eventual scaleup of the model to an actual siternapplication can be justified by the favorable results presented in this paper.
