Geotech SVE Spotlight   Geotech SVE


What is Soil Vapor Extraction?

Soil Vapor Extraction (SVE) extracts contaminants from the subsurface soil in a vapor form. Therefore, SVE systems are designed to remove contaminants that have a tendency to volatilize or evaporate easily such as volatile organic compounds (VOC's) and some semi-volatile organic compounds (SVOC's) beneath the ground surface in the unsaturated zone (i.e., Vadose Zone). By applying a vacuum through a series of underground wells, contaminants are pulled to the surface as vapor or gas.

Soil Vapor Extraction Applicability

The target contaminants group for in situ SVE are VOC's and some fuels. The technology is typically applicable only to volatile compounds with a Henry's law constant greater than 0.01 or a vapor pressure greater than 0.5 mm Hg (0.02 inches Hg). Other factors, such as moisture content, organic content, and air permeability of the soil, will affect the SVE's effectiveness. In situ SVE will not remove heavy oils, metals, PCB's, or dioxins.
Because the process involves a continuous flow of air through the soil, it often promotes the in situ biodegradation of low-volatility organic compounds that may be present.

Geotech March 2012 Photo Competition Winner

Greenland Geopump Sampling


Markus Dieser, from Louisiana State University, took these pictures of low-flow water sampling in front of the Greenland ice sheet near Thule Air Force Base.

Markus was using the Geotech geopump™ with piggy-backed pump heads for multiple sampling. A Geotech 12 Volt DC rechargeable battery provides the electrical power. Geotech 142 mm geofilter™ flatestock filter membranes mounted in a 142 mm Acrylic In-line Filter Holder filters the water samples.
