An attempt has been made to classify the groundwater by various methods of Nanjangud taluk. The Nanjangud taluk having an area of 981.60 sq.km and it falls under Mysore district of Karnataka. Water quality parameters of the waters samples were analysed and the results of the analysis have been used to suggest models for predicting water quality. Quality of groundwater in a hard rock terrain is more controlled by the rock-water interaction and the residence time of water in aquifers. The residence time in tum depends on the groundwater systems within a larger hydrological unit. The hydrogeochemical facies of groundwater in the taluk of kabini river basin of Mysore district in Karnataka has been determined. Based on water samples collected and analysed from 50 locations, the hydrogeochemical facies in the area are found to be dominated by sodium-bicorbonate type.
