RISK ASSESSMENT METHODOLOGY FOR PLANNING OF LANDFILL DISPOSAL SITE

Abstract

This paper describes the necessity and feasibility of application of risk concept for planning of landfill site. Risk assessment procedure has not been adapted for planning of waste treatment and disposal facility in japan. Moreover, CERCLA in U.S.A. requires the utilization of general risk assessment procedures for remedial actions of hazardous waste disposal sites but not planning of landfill site.
The purpose of this study is to develop the scientific and rational method of risk assessment for planning of landfill site, in order to improve the public health standard and to protect environment. Our developed risk assessment method is applied to a hypothetical problem as an example which deals with the selection of the best sealing method for leakage by using multiattribute decision analysis.
