Abstract

A system and method for the accelerated decontamination of contaminated soil, vadose zone (47) and/or groundwater (49) is described. Contaminates are removed from soil and from the groundwater (49) via heat injection through trenching or directionally drilled or horizontally drilled and installed delivery plumbing, pure oxygen injection through separate plumbing installed in the same manner as the plumbing used to deliver the heat, bioventing, sparging, and bioremediation, all through the oxygen delivery plumbing, and soil vapor extraction through vertical wells (31, 33), all contained in one mobile treatment system. Contaminants are separated from the soil gas via filtration or oxidation. Residual contaminants in the vadose zone and/or in the groundwater are subjected to volatilization by increased temperature via heat injection and/or oxidation via contaminant degrading microorganisms.
