"In this process electrodes are driven down into the area and electrical arcs are made to flow deep into the soils contaminated with toxic wastes or radioactive substances, liquifying the soil components and producing a non-permeable glassy material as the liquid soils cool. Once cooled this glassy residual can then either remain safely underground (since the toxic or radioactive wastes are now contained and cannot leach into groundwater or spread contamination) or they can be subsequently safely hauled away."
