Abstract:

This thesis investigated the effects of the slow sorption mechanism on the transport of volatile organic contaminants in the vadose zone. Recent research has shown that slow sorption may have a significant impact on the transport of volatile organic compounds in the subsurface. Specifically, this document examined the effects of slow sorption on the Vapor Extraction System VES and the Purge and Trap Measurement System. It was found that the slow sorption of organic molecules on soil may profoundly influence the efficiency of VES and purge and trap. In addition, this thesis investigated possible alternatives to purge and trap, including the utilization of lasers and optoelectronics. Mathematical simulation and modeling of slow sorption effects during vapor extraction operations was accomplished with the use of the Soil Vapor Extraction SVE Computer Model.
