Abstract
Soil vapor extraction (SVE)systems can be used to remediate enviornmental sites that have been contaminated with petroleum products. However, SVE systems rely on pore space in soils to draw the vapors through the soil, creating a vacuum. Therefore, SVE systems are not as effective when used in low permeability soils. This study aims to determine whether SVE systems can be used on low permeability soils in conjunction with companion technologies. The results indicate that SVE systems can be utilized in low permeability soils if used in conjunction with companion technologies that increase soil permeability and cantaminant volatilization. The promising companion technology is six-phase soil heating, based on contamination removal rate and cost estimates.
