Abstract. DRASTIC, with the use of different ratings criteria, has been widely used to evaluate aquifer vulnerability. Advantages of the DRASTIC model include the method's low cost of application and relative accuracy of model results for extensive regions with a complex geological structure. However, the current DRASTIC model has limitations including the lack of the aquifer data and low resolution maps. Thus, the objective of this study is to create a modified high-resolution DRASTIC approach (ver. 2012) for aquifer protection in a more reasonable and accurate way. This study should be extended to a larger area with more long-term water quality monitoring data for proper validation of DRASTIC (ver. 2012). After validation is done, this study is expected to be used as an efficient guide for managing groundwater resources by policy makers and groundwater-related researchers.
