Toxic contaminants dispersed throughout a section of earth can be removed by a process that includes applying liquid hydrogen peroxide to the earth surface, and exerting a vacuum force on the earth at a depth where the earth is relatively uncontaminated. The vacuum force evacuates the earth pores, to augment the gravitational force on the liquid hydrogen peroxide, so that the liquid is enabled to flow through the earth to chemically react with toxic contaminants. One or more vacuum pumps are connected with underground perforated pipes bordering the treated earth section, to produce the necessary vacuum force on the liquid hydrogen peroxide.
