Hazardous waste site remediation.
More than 150 sites in Hudson County, New Jersey are identified as chromium contaminated sites. Hexavalent chromium, highly soluble in water, is considered as an environmental and health hazard, classified as a group A human carcinogen. In this research, the feasibility was performed to study the possibility of remediation of chromium contaminated soil by ex-situ vitrification and to evaluate reuse potential of vitrified products as highway construction aggregate. A series of physical and chemical analysis was conducted on nine soil samples collected from different chromium contaminated sites. Results were analyzed for their compatibility for vitrification. Sand and carbon were added to enhance vitrification process. Vitrification was performed and the vitrified products were subjected to further chemical and physical tests. TCLP chromium concentration results verified a successful remediation. The vitrified product properties complied with the New Jersey Department of Transportation standards, designating high reuse potential.
