Abstract

A process is provided for vaporizing volatile contaminants present in soil and removing the contaminant vapors. The process involves heating the soil by passing current between electrodes buried in the soil and simultaneously injecting water under pressure through the electrodes to transfer heat by convection. The coupling of electrical heating with heat transfer by convection improves the efficiency and uniformity of heating. Th e contaminant liquids and/or vapors are removed by applying suction at extraction wells positioned between the electrodes.
