Abstract

 Khatounabad plain is located in the southeastern part of Iran. According to the weathering situation of the studied area, there isn't any permanent RIVER there and like other places of KERMAN province this area is dependent on groundwater. With a view to  the  existence of Khatounabad copper smelt factory  and also molybdenum factory on this plain and the importance of Khatounabad AQUIFER in providing water for industrial, agricultural, and drinking needs of the area, the vulnerability of Khatounabad  groundwater to pollution is studied in this paper, by using DRASTIC model. GIS is used for the preparation of the Khatounabad groundwater vulnerability map. This research shows that 8.54 percent of the studied area is located in high vulnerability situation, 63.55 percent in moderate vulnerability situation and 27.91 percent in low vulnerability situation. High vulnerability situation is located in the upstream part of the plain, so pollution could be distributed in the whole area form this part. Since factories of the area (Khatounabad copper smelt factory and also molybdenum factory) are located in the high vulnerability part of the plain, monitoring of soil and groundwater  is important. According to SENSITIVITY ANALYSIS, maximum sensitivity is related to unsaturated layer and minimum sensitivity is related to soil composition.
