An Environmental Impact Assessment Model with Monetary Valuation for Remediation in South Korea

Abstract

An environmental impact assessment model for soil remediation was developed to evaluate the environmental impacts of the remedial activities in both qualitative and quantitative way. It is a Microsoft Excel-based program containing seven soil remediation alternatives for South Korea. Qualitative evaluation provides a set of a checklist, and users can evaluate the environmental impacts by filling in the checklists. Four in-situ and three ex-situ remedial schemes are available in the quantitative evaluation. In quantitative evaluation, the quantities of energy, CO2, SOX, and NOX generated from the remediation technology are the results. The results are then converted into a single index, monetary value. Monetary value allows users to compare different remediation technologies by a single index. A case study is demonstrated to show applicability of this integrated environmental impact assessment program which is optimized for South Korea.
