Abstract

Air sparging is a remediation technique for contaminated soil using biodegradation and volatilization effect. This paper investigates direct visualization of injected air and its resistivity monitoring for air sparging. Behavior of air flow in a simulated soil composed of Plexiglas particles is observed, photographed and videotaped. The particle size and compaction affect the air flow. Air flows up as channels in fine particles. Its shape can be described as a parabola. We examined applying resistivity tomography to air sparging in the laboratory. And we detected the resistivity change by the injected air.
