Dual Phase Extraction System, Permitting Design, and Construction | Berkeley CA

A former industrial building located in Berkeley, California was impacted with Chlorinated Volatile Organic Compounds (CVOCs), including trichloroethene (TCE) and cis-1,2-dichloroethylene (cis-1,2-DCE); total petroleum hydrocarbons as gasoline (TPH-g), Dense Non-Aqueous Phase Liquid, and (DNAPL) and Light Non-Aqueous Phase Liquid (NAPL). A dual phase extraction system was permitted for site remediation.

Soil Vapor Extraction | Technology Description

Soil Vapor Extraction
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.

Groundwater Remediation using Air Sparge | Pilot Testing, Design, Construction, and Operation

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.
