Abstract
The present invention is a process to stimulate the biooxidation of a contaminant in a subterranean formation by introducing an aqueous solution into the formation. The concentration of the hydrogen peroxide is increased thereby acclimating the biota to higher concentrations of hydrogen peroxide. Periodically the concentration of the hydrogen peroxide is increased for a short time sufficiently to be toxic to the biota at or relatively adjacent to the site of introduction, thereby increasing the permeability of the formation at or adjacent to the site of introduction.
