Geotech Air Sparge Systems

Geotech Air Sparge Systems are designed to provide positive air pressure into the subsurface thus aiding the volatilization and biodegradation process associated with soil vapor extraction technology.

By injecting air directly into the groundwater, Geotech Air Sparge Systems remediates groundwater by volatilizing contaminants and enhancing biodegradation. Contaminants are removed from groundwater by physical contact with air and are carried up into the unsaturated zone (i.e., soil). As the contaminants move into the soil, a Geotech provided soil vapor extraction system (SVE) can be used to remove vapors from the subsurface.

Geotech custom designs and builds the following types of air sparge systems to be effective for your site requirements.
