Abstract:
A method for remediating a contaminated region of a subterranean body of groundwater to destroy or reduce the initial concentration levels of contaminants, comprising:providing at least one injection point extending from above ground to the subterranean body of groundwater; providing a supply of substantially pure liquid oxygen; converting said liquid oxygen to vapor oxygen; conveying said substantially pure oxygen vapor to a non-electrically operated regulating mechanism; delivering said substantially pure liquid oxygen vapor through said regulating mechanism to said at least one injection point and into the subterranean body of groundwater; and delivering an amount of microbials to said at least one injection point and into the subterranean body of groundwater to assist in reducing the level of contaminants; whereby pressurization of said supply of liquid oxygen and delivery thereof does not require electricity or any mechanical parts such that the method can operate continuously.
