Abstract: Various water quality parameters of underground water at different locations in Krishna district of Andhra Pradesh, India, were determined by using different analytical methods and the results were correlated to evaluate the corrosion rates of some important metals like carbon steel, copper and aluminium in the underground water samples. The study was performed for the underground water collected at seven different sites in the villages of Krishna district along the Krishna river. The analyzed parameters are chlorides, dissolved oxygen, conductivity, pH, total dissolved solids, total suspended solids, alkalinity and hardness. The trends of these physical and chemical parameters are analyzed. An attempt is made to evaluate corrosion rates of the metals, determined by gravimetric measurements, in terms of variations in the physical and chemical parameters.
