THE SCIENCE BEHIND THE TECHNOLOGY: SELECTED STABILIZATION CASE STUDIES OF MGP SITES

摘要

Today, Manufactured Gas Plants (MGP) sites are actively being remediated by a variety of technologies. The diversity of technologies being used at MGP sites is the direct result of the complexity of the chemicals associated with the wastes and the close proximity of former MGP sites to residential communities. As an example of the technologies available for MGP site remediation, this paper will discuss the full-scale implementation of deep soil mixing (DSM) stabilization at several sites. Moreover, the paper will illustrate the importance of a pilot demonstration test on large complex projects to determine the efficacy of the technology and binders selected for the work, as well as the quality control procedures used to ensure compliance with the intent of the contract specifications and treatability study. Additionally, one case study, recently published by the Electric Power Research Institute, discusses the superior performance and the long-term effectiveness of this technology at the Columbus MGP site, the conclusions of which are summarized in this paper.
