ABSTRACT OF THE DISCLOSURE An improved method and apparatus for removal of petroleum hydrocarbons from contaminated soil. The apparatus of the invention includes a shallow container, preferably with vertical sides, which has in its bottom wall a multiplicity of elongated recessed chambers with an open mesh entry area at the upper side, and a gas discharge orifice at one end of each chamber. A rack containing burners is adapted for positioning over the material to be treated within the container. The invented method includes charging materials to be treated into a container, heating the material while creating a partial pressure within the chamber, establishing a vacuum to pull the gasses, downwardly through the soil and atmospheric air downwardly with the gasses, then either collecting or discharging the removed gasses, after which the soil is removed from the treatment chamber. 16
