Pre monsoon and Post monsoon season’s of ground water samples were collected from the Kattangur watershed in Nalgonda district. The work has carried out based on geological, geomorphological and hydrogeochemical factors for the evaluation of major ions in ground water for drinking and irrigation use in a hard rock shallow aquifer. The physico-chemical parameters and major ion chemistry of the collected samples were analyzed. Based on the analytical results Wilcox and Gibbs diagram were plotted and distinguished ground water quality for the drinking and irrigation use. Wilcox plot suggest that most of the samples are within the permissible limits for drinking and irrigation use. The Gibbs plots have shown that the samples are rock dominance field mechanism for the grounds water chemistry in the Kattangur watershed. All the major ion parameters are shown within the permissible limits. It has been concluded that, the water from the study area is good for drinking and irrigation use, apart from few samples which are exceeded the limits due to anthropogenic activities and those samples were indisposed for irrigation.
