Back diffusion of contaminants from secondary sources may hamper site remediation if it is not properly addressed in the remedial design. A review of all reported technologies and strategies that have been or could be applied to address plu...
Field Study of Soil Vapor Extraction for Reducing Off-Site Vapor Intrusion [0.03%]
现场研究:采用土壤蒸汽提取法减少场地外的蒸汽入侵
Lloyd Stewart,Chris Lutes,Robert Truesdale et al.
Lloyd Stewart et al.
Soil vapor extraction (SVE) is effective for removing volatile organic compound (VOC) mass from the vadose zone and reducing the potential for vapor intrusion (VI) into overlying and surrounding buildings. However, the relationship between ...
