Description:
The primary objective of the Soliditech, Inc. solidification/stabilization demonstration was to develop reliable performance and cost information. he demonstration took palce at the Imperial Oil Company/Champion Chemical Company Superfund site in Morganiville, New Jersey. Contamination at this site includes PCBs, various metals, and oil and grease. The Soliditech process mixes the waste material with Urrichem, a proprietary regent; proprietary additives; pozzolanic materials or cement (cement was used for the demonstration); and water, in a open-topped concrete mixer. The technical criteria used to evaluate the effectiveness of the Soliditech process were contaminant mobility, based upon leaching and permeability tests; and the structural integrity of the solidifed material, based upon physical and morphological tests. The treated wastes had significant structural integrity, low permeability, and higher bulk density than the untreated wastes. H values of the treated wastes were highly influenced by alkalinity of the portland cement added during treatment. reatment resulted in significantly reduced concentrations of arsenic, lead, and zinc in (1) extracts from TCLP, EP Toxicity, and BET rocedures; and (2) leachates from intact cast cylinders subjected to ANS 16.1 and WILT procedures. CBs could not be detected in any extracts of leachates from treated wastes.
