Vertical movement and fate of trichloroethylene (TCE), originating from a point source, in the unsaturated zone was simulated by using a three phase solute-transport model. The model allows adsorption from the air and the aqueous phases to soil, and interphase transport between the air and the aqueous phases. The model equations were solved by using a forward time center space (FTCS) numerical scheme. Transient contaminant concentration profiles in the aqueous, the air and the soil phases were predicted. Emission rate of TCE across the ground surface to atmosphere and the leach rate to groundwater were estimated.
