Air Sparging

Sparging is a form of air stripping.

Sparging is the process where we bubble air into the groundwater through perforated pipes (wells) that penetrate the aquifers. We install pipes down into the saturated zone and perforate sections of the pipes under the water.

Then we pump air into the aquifer through the perforations. The air bubbles move up, strip the dissolved gasoline and get it evaporated into the air. The bubbles rise to the unsaturated zone where they get sucked into another series of perforated pipes connected to a vacuum machine. The vacuum machine sucks the air from the pipes and pumps it into a system that combusts the gasoline vapors or collects them in activated-carbon filters.
