Soil Vapor Extraction (SVE) is an in situ remediation technology designed to remediate soils impacted with volatile organic compounds (VOCs) including gasoline, and chlorinated hydrocarbons. This technology works by extracting soil vapor at a high vacuum using subsurface wells, then treating the soil vapor prior to discharge.
Air sparge is an in situ groundwater remediation technology which uses vertical or horizontal wells to transfer a continuous or pulsed flow air into the groundwater. The purpose of air sparge system is to reduce the concentrations of volatile organic compounds (VOCs) in groundwater through enhanced volatilization, and mass transfer of VOCs and oxygen.
