Abstract
Hydrogeochemical investigations were carried out in the south-eastern part of the Ranga Reddy district, Hyderabad, India, to assess the quality of groundwater for its suitability for domestic and irrigation purposes. The area falls under a semi-arid type of climate and consists of granites and pegmatites of igneous origin of Archaean age. Forty-five representative groundwater samples were collected from bore wells to monitor the water chemistry of various ions, comprising Ca+2, Mg+2, Na+, K+, CO3−2, HCO3−, SO4−2, NO3−, Cl− and F−. The results showed that the concentrations of these ions are above the permissible limits for drinking and irrigation purposes. The pollution with respect to NO3−, Cl−, and F− is mainly attributed to the extensive use of fertilizers and large-scale discharge of municipal wastes into the open drainage system of the area.
