If the slurry is considered hazardous only because it has a high pH, the slurry can be treated with an acid-based solution to bring it within acceptable levels. If the slurry is considered hazardous for other reasons, the particulate and water must all be disposed of so that it does not affect the environment. This may require the use of totally enclosed poly tanks or vacuum boxes, sealable 55-gallon drums or large lined dumpster filled a portion of the way to allow for transportation and removed off sight. Vacuum truck services may also be used to vacuum hazardous slurry out of holding containers and remove it from the site. Slurry solidification products are another option that can be used to absorb the water within the slurry turning it into a gelatin material that will pass EPA required testing to allow for its disposal in a regular landfill."
