Abstract

This study aimed to investigate the effective area where the air saturation and the dissolved oxygen concentration after air sparging can be enhanced using electrical resistivity tomography (ERT). Two soil tank tests were conducted. One was that air was injected to fresh soil model saturated with tap water, and this was control for the other test. The other was that air was injected to oil-contaminated soil model saturated with bacterial solution. Air was directly injected into each model for an hour, then the change of the air saturation and dissolved oxygen in the soil after that was measured. The air saturation after air sparging was related to the dissolved oxygen concentration. In conclusion, the air saturation distribution evaluated by ERT was an effective information to estimate the effective area where the dissolved oxygen concentration is enhanced after air sparging.
