Groundwater Cleanup by in-situ Sparging. II. Modeling of Dissolved Volatile Organic Compound Removal

Abstract

Simple steady-state and nonsteady-state models are developed for describing the removal of dissolved volatile organic compounds (VOCs) from aquifers by sparging techniques. A method is given for estimating the streamlines and transit times of water in a stagnant or nearly stagnant aquifer in the vicinity of a sparging well, and the resulting flow velocities are used to develop a model for the sparging of a VOC obeying Henry's law.
