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.
