Abstract: 
Assessment of groundwater vulnerability to pollution is a proper tool for groundwater protection. In this study, the modified version of DRASTIC model versus the original DRASTIC model was used to investigate the vulnerability potential of Urmia groundwater which has a potential for contamination due to various industrial and agricultural activities. Precision to this model was achieved based on the revising of the ratings and weights of various factors using correlation methods in GIS environment and taking into account the correlation with the concentration of groundwater nitrate. The results showed that aquifer environment (A) did not have a significant correlation with nitrate concentration and was accordingly eliminated from the initial equation. The highest and lowest significant correlation was respectively found between soil factors (s) and depth to groundwater (D) and weighed 5 and 2. 7, respectively. The correction of ratings and weights led to improved zoning map with an increased correlation of DRASTIC index with nitrate concentration versus the original DRASTIC by 11%. Based on the modified index, 4. 3, 30. 8 and 64. 9 percent of the Urmia Plain were ranked as low, very low and without risk of pollution, respectively.
