Description:
Soil vapor extraction (SVE) systems are being used in Increasing numbers because of the many advantages these systems hold over other soil treatment technologies. SVE systems appear to be simple in design and operation, yet the fundamentals governing subsurface vapor transport are quite complex. In view of this complexity, an expert workshop was held to discuss the state of the art of the technology, the best approach to optimize system application, and the process efficiency and limitations. As a result of the workshop an SVE Technology Assessment report was produced. This report discusses the basic science of the subsurface environment and subsurface vapor flow, site Investigations, SVE system design and operation, and includes selected papers from the expert workshop. Additional research activities being conducted include a field demonstration of a structured SVE system design approach, a laboratory column study to determine and characterize residuals following vapor extraction, an assessment of secondary emissions and regulations governing releases from SVE systems, cost of SVE implementation and operation, and a survey of techniques to enhance vapor removal.
