Abstract

This research is an evaluation of vulnerability of KHASH-PLAIN AQUIFER to POLLUTION, using DRASTIC MODEL and Geographic Information System (GIS). Seven environmental parameters have been used to represent the hydrogeological nature of the AQUIFER. These parameters are: depth of water table, net recharge, AQUIFER media, soil media, topography, impact of vadose zone, and hydraulic conductivity. This study shows that the Khash AQUIFER consists of two main zones: low GROUNDWATER vulnerability risk zone (risk indexes 92-121) and moderate GROUNDWATER vulnerability risk zone (risk indexes 122-148). Areas with moderate and low risk zones comprise 75.5% and 24.5% of the studied area, respectively. Statistical analyses have been carried out using nitrate ion concentration. Two tests of SENSITIVITY ANALYSES were carried out: the map removal and the single-parameter SENSITIVITY ANALYSES. Based on the characteristics of the studied area, the results from both map removal and single-parameter SENSITIVITY ANALYSES showed that the net recharge parameters have the most significant impact on the vulnerability risk zones.
