What Does Soil Vapor Extraction (SVE) Mean?
Soil vapor extraction (SVE) is a method used to extract volatile and semi-volatile contaminants from the soil by using vacuum pressure. The remediation process utilizes the volatile nature of petroleum hydrocarbons as the primary method and the vapor pressure difference between petroleum and water or soil.
Air sparging is used in conjunction with soil vapor extraction (SVE) to allow the air bubbles to carry the contaminants in the vapor phase to remove them. The vapor plume migration takes place when the SVE system with the help of extraction wells creates a negative pressure in the unsaturated zone.
