Hydrogeochemistry of Groundwaters in Kushaiguda region, Reddy district, Andhra Pradesh, India has been analyzed to evaluate its aptness for domestic and agricultural uses. Sixteen samples of groundwater were collected and evaluated the different physico chemical parameters namely, pH, Total hardness (TH), Electrical conductivity (EC), Total dissolved solids (TDS), cations such as Ca2+, Mg2+, Na+ and K+ and anions such as CO32-, HCO3-, Cl- and SO42-. Different irrigation water quality parametersand diagrams such as, Permeability index (PI), Kelley’s ratio (KR) and Wilcox plot revealed that most of the water samples are suitable for irrigation. Gibbs plot suggests that the qualities of most of the samples are influencing the chemical weathering of rock forming minerals. Piper plot and Durov plot indicates the chemical composition of water, chiefly controlled by dissolution and mixing.
