A system and method for the decontamination of contaminated ground is described. Contaminated soil gas containing the contaminant is removed from the contaminated ground. Contaminants are separated from the contaminated gas and treated to lessen an environmental hazard of the contaminant. Contaminants are preferably treated by non-thermal oxidation. Residual soil gas, including any oxygen, unoxidized contaminants, and oxidation products (water vapor and carbon dioxide) are returned to the ground, where unoxidized contaminants are subject to oxidation by soil microorganisms. The returned residual soil gas is recirculated through the decontamination system.
