The present study deals with the ground water quality with respect to fluoride in villages of Vinukonda Mandal, Guntur District, Andhra Pradesh, India. Ten ground water samples are collected from ten different villages for determining various physicochemical parameters such as pH, EC, TDS, TA, TH, Turbidity, Ca2+ Mg2+, Na+, K+, Cl-,NO3 ,HCO3 ,SO4,PO4, F- and DO. The observed values of these parameters of the samples are compared with standard values recommended by Indian Standards and World Health Organization (WHO). Fluoride concentration in the study area is ranged between 3.28 to 4.27 mg/lit. Overall water quality is found unsatisfactory for drinking purposes without any prior treatment. A systematic correlation and regression study shows a significant linear relationship between different pairs of parameters to identify the highly correlated and interrelated water quality parameters. After treatment with activated carbons, NVNC, NSOC, NAbIC and NAcIC, the concentrations of all physicochemical parameters of the samples are reduced to permissible levels.
