Abstract

One of the best ways to prevent groundwater contamination is to identify aquifer VULNERABILITY areas, monitor spatial quality changes and, then, manage water resource exploitation and land uses. In this study, aquifer VULNERABILITY has been studied by using a DRASTIC MODEL in SARKHON. Thus, the geographic information system (GIS) has been used to provide an aquifer VULNERABILITY map and seven HYDRO-GEOLOGICAL FACTORS influencing VULNERABILITY have been studied. The results show that 70% of the area affected has moderate VULNERABILITY, 27.5% has high VULNERABILITY and 2.5% has low VULNERABILITY. In both of the SENSITIVITY ANALYSIS methods, the map removal and single parameter was assessed. The DRASTIC VULNERABILITY index was most responsive to both SENSITIVITY ANALYSIS methods and shows the effect of vados zone results from a single parameter SENSITIVITY ANALYSIS of the study area. This shows a depth of parameter, the most important criterion in assessing the VULNERABILITY of but, unexpectedly, the lower impact on the VULNERABILITY of the study area, weight and a significant difference of about 12% with the weight theoretical. Nitrate ion measurements were taken from multiple wells (water and agricultural) and were used in order to verify the measurement accuracy of the model. The results indicate the high accuracy of the model for the area studied.
