ABSTRACT:
An apparatus and method is disclosed for an improved mobile apparatus for removing contaminants from a site containing granular material with the contaminants being affixed thereto. The mobile apparatus comprises a processor which extracts the granular material containing the contaminants from the site. The processor containing a liquid agent separates the contaminants from the granular material and creates a slurry comprising the granular material, the liquid agent and the contaminants. A conduit conducts the slurry from the processor to a mobile reservoir. A separator extending angularly relative to the mobile reservoir conveys the granular material, the liquid agent and the contaminants away from the mobile reservoir and separates the granular material from the liquid agent containing the contaminants.
