Abstract: The 21st century has been declared the century of water, and we have every responsibility to find proper solutions to water crisis witnessed all over the world. A large part of the world’s population especially people living in the developing countries is experiencing water stress resulting in water shortages and pollution. In many areas, water supplies for industrial, domestic and agricultural needs are dependent on groundwater. More than 85% of the rural water supply is being provided through groundwater. It is observed that areas experiencing declining water levels are also facing the problems of increase in the concentration of solutes, which may result in the deterioration of groundwater quality. In view of this, two sub-watersheds located in semi-arid region (water stressed region) in Southern India Karnataka State, Bangalore rural district, Dodballapur Taluk are taken up for intensive studies, broadly covering hydrologic, soils, water(surface and sub-surface) quantity and quality, water requirement of crops and the like

Keywords: chemical classification, chemical characteristics, groundwater, water quality, water hardness
