Abstract
A method of performing soil decontamination including mechanically mixing the soil with solid oxidant prior to any addition of water and until an exothermic reaction between the oxidant and contaminants within the soil occur, adding only necessary water to obtain an homogeneous mix between the soil and the oxidant, and mechanically mixing the soil with the oxidant and the water for a predetermined period of time to allow the oxidant to at least partially oxidize the contaminants.
