Application AHP-PROMETHEE Technic for Landfill Site Selection on Based Assessment of Aquifers Vulnerability to Pollution

Abstract Choosing a suitable location for the disposal of municipal solid waste is an important environmental problem. Thus, locating landfill has been very important. Leachate from causes contamination groundwater. However, process complicated and based on qualitative quantitative criteria. Therefore, in this paper, hybrid approach determining optimal presented. Additionally, present study attempts to evaluate potential aquifer vulnerability proposed sites using DRASTIC model Plain Zanjan provide zoning map vulnerable areas. In study, mapping used. This consists seven hydrogeological parameters effective contaminating aquifer. The appear GIS software as layers which analysis performed. Considering with regard at various areas, it possible determine site landfill. At present, about 49.03% aquifers are average situation; by considering them, can be determined. Accordingly, considered criteria were determined AHP method; weights determined, then appropriate places classified into three classes, high, moderate or low, software. Finally, zones located high classes selected best locations PRPMOTHEE method, taking account scientific limitations conditions area. results showed that methods paper option disposal. future, there lot studies modeling choose due some soil characteristics applying other models pollution groundwater region.
