Evaluation of waste stabilized by the Soliditech site technology

Technical Report ·
OSTI ID:5605824
The Soliditech technology demonstration was conducted at the Imperial Oil Company/Champion Chemicals Superfund Site in Monmouth County, New Jersey. Contamination at the site includes PCBs, lead (with various other metals) and oil and grease. The process mixes the waste material with proprietary additives, pozzolanic materials, and water, in a batch mixer. Technical criteria used to evaluate its effectiveness include (1) short-term extraction and engineering tests; (2) long-term extraction and and leaching tests; (3) petrographic examination; and (4) structural integrity observations. Three different waste types-contaminated soil, waste filter cake material and oily sludge-and a sand blank were treated. Neither PCBs nor volatile organic compounds were detected in the extracts of treated wastes. Significantly reduced amounts of metals were detected in the extracts of treated wastes compared to untreated.
