Groundwater is considered to be one of the most important sources of water for domestic use, agriculture and industrial use in study area. The aim of this study is to determine the ground water vulnerability index using the DRASTIC model. The objective is to determine the susceptible ground water zone by integrating various layers using ArcGIS. Attributes such as depth to ground water, net recharge, aquifer media, soil media, topography, impact of vadose zone and hydraulic conductivity are considered for ground water vulnerability mapping for the study area. The ground water vulnerability index was classified into four classes viz. 100-120, 120-140, 140-160 and 160-180 corresponding to low, medium, high and very high vulnerability respectively. The vulnerability map depicts that 20.50%, 16.92%, 41.81% and 20.78% area of the Ahmedabad district falls under low, medium, high and very high vulnerability zones respectively. The present model can be used as a supplement for planning urban and industrial development in the study area.Conference Paperhttps://www.researchgate.net/publication/312791659_Application_of_DRASTIC_Model_Using_GIS_for_Evaluation_Of_Ground_Water_Vulnerability_Study_of_Ahmedabad_District
