Title: Air channel distribution during air sparging: A field experiment

Air sparging may have the potential to improve upon conventional groundwater treatment technologies. However, judging from studies published to date and theoretical analyses, it is possible that air sparging may have a limited effect on aquifer contamination. The basic mechanisms controlling air sparging are not well understood, and current monitoring practice does not appear adequate to quantitatively evaluate the process. During this study, the effective zone of influence, defined as the areas in which air channels form, was studied as a function of flowrate and depth of injection points. This was accomplished by conducting the air sparging test in an area with shallow standing water. Air sparging points were installed at various depths, and the zone of influence was determined visually.
