The USEPA had developed an index system called DRASTIC to assess the potentiality of groundwater pollution (GPP). The attributes considered by DRASTIC are D (Depth to water), R (net Recharge), A (Aquifer media), S (Soil media), T (Topography), I (Impact of a vadose zone), and C (Conductivity of an aquifer). Evaluation of these attributes is generally expensive, uncertain, and perhaps inadequate, especially for A, I and C. This study, a fuzzy set method was proposed. The method was implemented by a geographical information system (GIS) to generate various geo-referenced maps for D, R, A, S, T, I, and C based on several pre-specified membership functions. With some fuzzy calculation and map analysis functions provided by the GIS, an overall fuzzy-GPP map can be obtained for a user-provided siting area. The map of fuzzy-GPP can then be incorporated into a mathematical model to locate appropriate candidate sites. A case study for municipal solid waste landfill siting analysis was presented. Various landfill siting related GIS maps were collected for a study area. The proposed fuzzy DRASTIC index was applied to the study area. Results obtained from the fuzzy and the original DRASTIC index were compared and discussed.
