ABSTRACT:
A method to disinfect a porous solid medium, such as soil, includes the steps of embedding a plurality of electrodes into the porous solid medium and applying a plurality of alternating current voltage pulses between the electrodes. The voltage pulses have a peak voltage of at least 10 kilovolts and are of an intensity and duration effective to generate a quantity of ozone. The ozone is produced in quantities sufficient to disinfect the porous solid medium.
