Remediation of Chromium-Contaminated Soils Pilot-Scale Investigation:
Abstract: "This paper describes the results from the pilot-scale demonstration study performed to remediate chromium-contaminated soil by Cold Top ex situ vitrification. Demonstration tests were performed on soils from two sites, containing residue from two types of chromite-ore processing. The primary objective of this demonstration was to determine if the waste processed by the Cold Top vitrification system meet the Resource Conservation and Recovery Act (RCRA) definition of a nonhazardous waste based on leachable chromium content in the waste. Excavated soils from two sites were crushed sieved, dried, and amended with carbon and sand and then shipped to a Cold Top vitrification plant. Cooled casting of the vitrified products were crushed and grounded for chemical analyses. The TCLP test results confirmed the effectiveness of the treatment...."
