Abstracts: Surface water quality can be determined by hydrological responses that vary geographically. The sub-surface hydrologic environment, however, has a primary influence on groundwater movement and hence pollutant migration to the subsurface water. Maps of aquifer vulnerability to pollution are becoming more in demand because on the one hand groundwater represents the main source of drinking water, and on the other hand high concentrations of human/economic activities, e.g. industrial, agricultural, and household represent real or potential sources of groundwater contamination. There is a need to conduct studies on groundwater pollution. The main objective of this paper is to find out the groundwater vulnerable zones in shallow aquifers in anand and its surrounding areas, which is one of the fastest growing big cities of north India, using the DRASTIC model in a Geographical Information System (GIS) environment. This model is based on the seven data layers that provide the input to the modeling. It corresponds to the initials of seven layers i.e. Depth of water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone and hydraulic Conductivity.
