Abstract

The aim of present investigation is to determine the ground water resource has useful for drinking and irrigation purpose of Yerpedu area, Chittoor district. From that 25 water samples have been collected with different intervals. The physico chemical parameters were analyzed with help of ICP-OES instrument, determine the physicochemical parameters like cations and anions. Based on that, Evaluation of the irrigation parameters like such as the residual sodium carbonate, percent sodium, potential salinity, Kelly's ratio, chloroalakaine indices, magnesium ratio, SAR and permeability index. The Gibbs diagramme was represented the rock-water interaction. The Prominent water type was Ca-Mg-Cl facies.
