ABSTRACT:
A method and apparatus for removing volatile contaminants from the phreatic zone of contaminated ground. The apparatus is a system comprised of at least one air injection well and at least two pressure relief wells arranged in a line. Air is injected into the contaminated ground water to allow sparging of the volatile contaminants from a linear region between injection and relief wells. The volatile contaminants are captured by the injected air and carried to the extraction line for removal and treatment.
