Sustainability Assessment of Excavation and Disposal versus In Situ Stabilization of Heavy Metal-Contaminated Soil at a Superfund Site in Illinois
The Matthiessen and Hegeler Zinc smelting site in Illinois was designated as a Superfund site in 2005 for its high concentration of heavy metals. Through multiple comprehensive field investigations, the Illinois EPA collected soil and sediment samples from the site and the adjacent residential community. Among other contaminants, zinc was found to be present at elevated levels in all samples, and cadmium and lead were elevated in all but one sample. The large surface area of the contaminated site, more than 40 hectares (100 acres), poses a challenge for treatment. Two alternative treatment methods were evaluated for long-term sustainability: the traditional method of excavation, hauling, and disposal in a hazardous waste landfill and an in situ remediation approach via solidification/stabilization. The life cycle assessment for each alternative was performed using SimaPro for energy inputs and environmental releases through all stages of manufacturing of materials needed for remedial operations, transportation, and remedial implementation. It was found that due to the large quantity of contaminated soil that is required to be excavated and hauled to the nearest landfill, the in situ method of solidification/stabilization was the more sustainable option in the long term. Other aspects associated with sustainability include social and economic impacts; both are discussed in the remedial options.
