ABSTRACT: STIMULATION OF BIOOXIDATION PROCESS IN SUBTERRANEAN FORMATIONS 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 per- oxide is increased thereby acclimating the biota to higher concentrations of hydrogen peroxide. Peri- odically 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 perme- ability of the formation at or adjacent to the site of introduction.
