Soil vapor extraction well
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. WebMar 2008 - Jul 20135 years 5 months. Salt Lake City, UT.
