Air sparging coupled with soil vapor extraction has been developed and applied to remove volatile contaminants from subsurface environment instead of groundwater extraction coupled with soil vapor extraction. In this paper, laboratory experiments, usinglmm glass beads as the porous medium, were conducted to investigate air spa rging performance. The purpose of these experiments was to observe the basic mechanisms of injected air flow pattern and dissolution of oxygen in the saturated porous medium during air sparging. The results obtained in this study were as follows. The continuous air channels formed inside the porous medium when the grain size of the medium was lmm. The pulsed operation for air injection can spread the region of injected air flow and supply oxygen into groundwater more than the continuous operation.
