ABSTRACT:
A method and apparatus for removing volatile contaminants from the phreatic zone of a contaminated region in the ground. The apparatus is a system comprised of a trench cut into the phreatic zone of contaminated ground containing fluid-permeable fill material, an air injection line submerged in the lower portion of the trench and an air/contaminant gas extraction line in the trench above the water table. Air is injected into the contaminated ground water to allow sparging of the volatile contaminants. The volatile contaminants are captured by the injected air and carded to the extraction line for removal and/or treatment.
