THE SCIENCE BEHIND THE TECHNOLOGY: SELECTEDSTABILIZATION CASE STUDIES OF MGP SITES

摘要

Today, Manufactured Gas Plants (MGP) sites are actively being remediated by a variety ofrntechnologies. The diversity of technologies being used at MGP sites is the direct result of therncomplexity of the chemicals associated with the wastes and the close proximity of former MGPrnsites to residential communities. As an example of the technologies available for MGP siternremediation, this paper will discuss the full-scale implementation of deep soil mixing (DSM)rnstabilization at several sites. Moreover, the paper will illustrate the importance of a pilotrndemonstration test on large complex projects to determine the efficacy of the technology andrnbinders selected for the work, as well as the quality control procedures used to ensurerncompliance with the intent of the contract specifications and treatability study. Additionally, onerncase study, recently published by the Electric Power Research Institute, discusses the superiorrnperformance and the long-term effectiveness of this technology at the Columbus MGP site, thernconclusions of which are summarized in this paper.
