ABSTRACT
This chapter discusses the stripping process to remove dissolved, volatile compounds from water. A carrier gas is purged through the contaminated water with the volatile components stripped from the water in to the gas phase. Computer modeling was used to analyze the theoretical effectiveness of many groundwater purging and soil flushing options. The objective was to select the combination of pumping and soil flushing that would result in expedient capture of the entire plume and also result in a reasonably shaped cone of depression to minimize withdrawal of unimpacted groundwater. The practical solution that was selected consisted of three wells with a combined pumping capacity of 300 gpm, treating the groundwater, and disposal of the effluent into an on-site seepage basin. Based upon the results of investigative work, three free product recovery wells were installed to capture the floating product. The AquaDetox process was designed for continuous, reliable service with minimal maintenance.
