Description:
Soil vapor extraction (SVE) is a technique that is used to remove volatile organic compounds from unsaturated soils. ir is pumped through and from the contaminated zone to remove vapor phase constituents. n this work, laboratory soil column experiments were conducted using a gasoline residually saturated sandy soil to evaluate the performance of SVE under controlled conditions. ath vapor extraction and aqueous leaching of the soil columns were conducted. he progress of the vapor extraction event was continuously monitored by an in-line total hydrocarbon analyzer. erformance of vapor extraction was evaluated by a series of soil chemical analyses Including total petroleum hydrocarbons, headspace measurements, and extraction techniques with quantification b GC/FID and GC/M$. ontaminant levels in aqueous percolate were compared be re and after SVE.
