Abstract
The flow and transport of organic compounds in variably saturated poro us media is investigated using a compositional simulator. The simulato r incorporates a number of numerical options to maximize computational efficiency and accuracy. The effect of field scale heterogeneities on the movement of organic compounds is demonstrated. The influence of i nfiltrating wetting fronts on gas phase transport of volatile organic compounds is shown to be significant. The long-term fate of a subsurfa ce spill of a three-component dense organic liquid is simulated. Three -dimensional simulations of soil vacuum extraction demonstrate the dif ficulty in removing dissolved organic compounds from the saturated zon e with this process.
