Groundwater contamination by volatile organic compounds(VOC), like trichloroethylene gives a serious environmental problem because of their carcinogenic characteristics in our health..Behaviors on dissolved material in porous media consist of two parts, volatile gases migration in unsaturated zone and liquid phase dispersion in groundwater. The objective ofthe study aims at the modeling of contaminant migration in soil and groundwater. The results of the study in shallow unsaturated soil showed that moisture plays important role in the vaporization and condensation process and rainfall infiltration enhances the downward transport of contaminant. Referring to laboratory experiments and field scale data, a new numerical model on migration in unconfined groundwater was developed by using the random walk method coupled with the finite difference descretization.
