This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated terminology they have once learned, and enlighten the uninitiated on terms they may have heard but never knew the meaning of.

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.

Air sparging woks also for chlorinated solvents, except that the treatment unit is replaced with activated-carbon filters.

You can find past issues of our  "Environmental Enlightenment" at amiadini.com Wealth of information about environmental site assessments in the real estate transactions and issues concerning assessment and cleanup of contamination in the subsurface soil and groundwater.

Call me if you have any questions. There are no obligations.
