Water is used for drinking, domestic, agricultural and industrial etc., one of the sources for drinking is groundwater, over usage of groundwater has been contaminated in different region due to dissolved minerals from rocks, industrial effluents and salt water intrusion. The groundwater samples are collected from selected sampling stations in and around of Gudlavalleru town region, Krishna district, and assess the physic-chemical characteristics, and tested the water quality parameters like pH, EC, TDS, TH, SO4, Cl, Mg, K, Na and F. The statistical method involves determination of correlation between the parameters. Finally it was found that there is a high concentration of parameters in ground water during both pre and post monsoon seasons, it indicates a serious health problems will rise in human. Therefore, to protect the public, it is necessary to treat and monitor the water quality before consumption in the study area.
