ABSTRACT:
A system and method of remediating a ground site contaminated with volatile chemical material such as volatile organic compounds (VOC). The system includes an array of elongated spaced dewatering wells embedded into the contaminated ground for lowering the ground water level in this area. The system also includes an array of spaced vacuum extraction wells also embedded in the contaminated ground for removal of air mixed with the volatile contaminates after the ground water level has been lowered below the level of the contaminated ground. By this arrangement, both contaminated ground water and volatile contaminants are removed for disposal to greatly increase both efficiency and long-lasting effect. After remediation, the uncontaminated surrounding ground water flows back to further cleanse the now remediated ground.
