The current paper aims at determining the status and patterns of groundwater quality of Chinnamandem Mandal, Y.S.R Kadapa district, Andhra Pradesh by applying the water quality index method. For this study, twelve groundwater samples were collected in 2019 and analyzed for pH, EC, TDS, total hardness, calcium, magnesium, chloride, fluoride, bicarbonate, nitrate and sulphate. The computed water quality index value for the groundwater ranges from 28.004-84.157. The analysis results reveal that few of the groundwater samples parameters, like EC, TDS, total hardness, calcium, magnesium, chloride and bicarbonate exceed the WHO standards but overall the water quality index was found to be good for drinking. This study focuses on the importance of water quality indexing for groundwater quality assessment which helps to take necessary steps to avoid the use of contaminated water in this area.
