“…Considering the correlation analysis results, it was seen that the AHP-DRASTICLu model provides more accurate results than the DRASTIC model in terms of the sulfate and chloride contents of the groundwater except for the electrical conductivity in the UKV. In many studies conducted to determine the groundwater vulnerability to pollution, the nitrate [31,100,101], sulfate [102][103][104], and chloride [29,105] concentrations of groundwater were used to validate the model results. It was seen that the vulnerability index values were highly correlated with sulfate in some areas [106,107], chloride in some areas [35,108], and nitrate in some areas [36,109].…”

“…In cases where an indicator is categorized into three ranges, its ratings were adjusted to 0.1, 0.3, and 0.7. The delineation of factor ranges and assignment of ratings are derived from previous studies [94][95][96][97][98]. The ranges and ratings of all indicators are presented in Table 2.…”
