Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase contamination at extraction wells. Extracted contaminant mass in the gas phase (an… WebSoil vapor extraction (SVE) is a commonly used technology for VOCs in soils that EPA has selected as a “presumptive remedy” (see bibliography at the end of this paper). SVE is an in situ treatment technology that uses vacuum blowers and extraction wells to strip volatile compounds from unsaturated soil. iowa state university covid vaccinationWebA horizontal soil vapor extraction system has a longer interval of screen in contact with the contaminated zone and provides a greater recovery in the vertical dimension, creating a much greater zone of influence than typically can be achieved with vertical wells.
