Analysis of remedial alternatives of the Nanji Landfill,Korea

 This paper presents an analysis of various remedial alternatives for a representative waste disposal site causing serious adverse affects to the surrounding soil and surface and groundwater systems and discusses the application of this approach in a case study. The numerical flow model along with the transport model in three dimensions were utilized to simulate current flow conditions at the site and its vicinity for calibration and to provide the analysis results for various remedial alternatives, such as top capping, vertical barrier, extraction, and hydrodynamic control. While the development of remedial alternatives and the selection of the most effective remedial measures are highly site-specific, the approach and methodology presented in this paper have general applicability. The conditions outlined in this study are used by environmental engineers and planners who incorporated economic and engineering decisions and public acceptance for various remedial measures considered; they also provide insight into the difficulties and special considerations associated with modeling and analyzing remedial alternatives.
