Description:
The major objective of the Soliditech, Inc., SITE demonstration was to develop reliable performance and cost information about the Soliditech solidification, stabilization technology. The Soliditech process mixes hazardous waste materials with Portland cement or pozzolanic material (such as fly ash), a proprietary reagent called Urrichem, proprietary additives, and water to aid in the physical and chemical immobilization of the hazardous waste constituents. The demonstration took place at the site of a former chemical processing and oil reclamation facility in Morganville, New Jersey. Site contamination included petroleum hydrocarbons, PCBs, other organic chemicals, and heavy metals. The technical criteria used to evaluate the effectiveness of the Soliditech process were contaminant mobility based upon extraction, leaching, and permeability tests; and structural integrity of the solidified material, based upon measurements of physical properties. Extensive sampling and analyses indicated (1) a reduction of heavy metals in the extract or ieachates of the solidified waste samples, (2) no volatile organic compounds in the TCLP extract of the solidified waste, (3) detectable levels of phenols and cresols in the TCLP extract of the solidified waste samples, (4) the process is capable of solidifying wastes containing moderate levels of oil and grease, and (5) structural stability in the solidified waste with moderate volume increase.
