Soil Vapor Extraction/Air Sparge Remediation Systems

What Is Soil Vapor Extraction/Air Sparge Remediation Systems?

Soil Vapor Extraction (SVE) is an in-situ remediation technology that involves the installation of a series of “wells” in the contaminated soil above the water table and placing a negative pressure on wells in the vadose zone to pull contaminated soil vapors from the subsurface soils. Air sparging is an in-situ remediation technology in which air is injected through a contaminated aquifer over the period of a few months to a few years. The injected air moves in all directions away from the injection point through the groundwater and soil matrix creating an underground, in-situ “air stripper” that removes contaminants by volatilization. The injection of air helps to flush the contaminants upward into the unsaturated zone where a vapor extraction system is typically implemented to remove the volatilized contaminants. Both methods are used for chemicals that evaporate easily like those found in solvents and gasoline.
