ABSTRACT:
A bioremediation method and system for destroying or reducing the level of contaminants in a contaminated subterranean body of water includes a plurality of spaced injection sites. The injection sites extend below ground and intersect a body of groundwater. Each of the plurality of injection sites are in communication with a supply of concentrated oxygen. The oxygen is conveyed by a delivery mechanism from the supply of oxygen to the injection points to naturally reduce the contaminants in the groundwater. The amount of oxygen delivered to the groundwater is maintained such that the amount of oxygen in the soil gas vapor is between 15% and 25%.
