Hydrogeochemical investigations were carried out in semi-arid region of Basara to estimate the quality of groundwater for its suitability for domestic and agricultural purposes. For this region 34 groundwater samples were collected in different locations and analyzed for various ions, viz., Na+, Ca2+, Mg2+, K+, Cl−, HCO3−, SO42−, CO32−, HCO3−, NO3− and F− to assess the water chemistry with sodium absorption ratio, %Na, residual sodium carbonate, magnesium hazard.
