Geochemical Studies of Groundwater in HebbahallaWatershed, Mysore District, Karnataka, India

Abstract

Geochemical studies were conducted to find out the variation of chemical studies in Hebbahalla watershed. The groundwater sample collected from fifty-bore wells sample in different locations for pre and post monsoon season. As the groundwater quality varies from one season to another season, it is necessary to measure the spatial distribution and variation between the seasons, so the sample data have been collected during pre and post monsoon season in the year of 2013. The result of each parameters have been linked with the GPS location data in the Geographical Information System (GIS) to find out the spatial distribution and variation of groundwater and interpolation technique named Inverse Distance Weighed(IWD) in ArcGIS has been used based on fifty sample results. The chemical components of parameters such as Na, Ca, K, Mg, Cl, HCO3, SO4, NO3, EC, TDS, PH.
