Glossary entry:Soil vapour extraction
Meaning in EUGRIS: Soil vapor extraction, also known as 'soil venting' or 'vacuum extraction', is an in situ remedial technology that reduces concentrations of volatile constituents asorbed to soils in the unsaturated zone. In this technology, a vacuum is applied through wells near the source of contamination. Volatile constituents of the contaminant mass 'evaporate'. The vapors are drawn toward the extraction wells to be treated as necessary before being released to the atmosphere. The increased air flow through the subsurface can also stimulate biodegradation of some of the less volatile contaminants.
