Soil vapor extraction (SVE) is a remediation technology that uses vacuum to remove low-molecular weight or volatile contaminants in the vapor-phase from subsurface soils at a low cost, and with minimal disruption to business operations. This technology is a viable remediation option in fine- to coarse-grained (sand and gravel) sediments. SMA has designed, pilot-tested, installed, operated, and maintained SVE systems across the Midwest. The image below shows how an SVE system effectively removed perchloroethylene (PCE) vapors from subsurface soils at an active dry cleaner in less than one year.
