Abstract: The vulnerability of Loor basin aquifer was quantified in Khouzestan province to evaluate the risk of groundwater pollution. DRASTIC model and geographic information system (GIS) were used to analyze groundwater quality. The seven layers of DRASTIC model including depth to groundwater, net recharge, aquifer media, soil type, topography, regional characteristics of unsaturated hydraulic conductivity were prepared in ArcGIS software. The validation of the model was assessed by overlapping pollution risk map and measured nitrate concentrations and results showed that none of the places with high nitrate concentration were located in the part of Low pollution that could confirm the accuracy of the model. The north part of Andimeshk city is in the range of medium to high vulnerability and these areas the area should be under control to prevent groundwater pollution.
