Groundwater Quality in Twin Microwatersheds near Keralapura, Hassan District, Karnataka

Quality of groundwater in a hard rock teriam is more controlled by the Rock-Water interaction and the residence time of water in aquifers. The residence time in turn depends on the groundwater systems within a larger hydrological unit. The hydrogeochemcial facies of groundwater in the twin watersheds of Cauvery basins near Keralapura of Hassan district Karnataka has been determined. Based on water samples collected and analyzed from 32 locations during Pre-and Post-Monsoon seasons, the hydrogeochemical facies in the area are found to be dominated by sodium-Bicarbonate type.
