摘要： An in situ air sparging/soil vapor extraction apparatus includes first, second and third concentrically arranged pipes disposed in a single bore hole. The first pipe extends a first length through the bore hole to discharge pressurized gas from a second end. The second pipe surrounds the first pipe and extends a second distance, less than the first length of the first pipe, through the bore hole to discharge pressurized gas from the second end of the second pipe at a different level in the soil then the pressurized gas discharged from the second end of the first pipe. The third pipe surrounds the second pipe and is connected to a low pressure source to extract substantially all of the air discharged through the second ends of the first and second pipes and the contaminants entrained in the air from the soil and groundwater.
