Abstract: The uncertainty associated with the availability of surface water both in terms of quantity and quality made people to depend on ground water. But in recent years, depletion of water table and mineral contamination like Fluoride are the causes of concern. Some previous studies show people affected with symptoms of Fluoride contamination in Hungund area. Hence to analyze the fluoride content and other co-relating parameters we selected some bore wells in Amingad and Kamatgi of Hungundtaluk, Bagalkot district of Karnataka. Our study mainly comprises of determining the mineral parameters present in groundwater with emphasis on fluoride. The water samples from the bore wells of above two places are collected and parameters like Total Hardness, Fluoride, Alkalinity, Acidity, pH, Conductivity, Chloride and Sulphates are analyzed in the laboratory. The obtained fluoride concentration is correlated with other parameters.Along with the parameters, the geological strata surrounding the selected bore well is identified and correlated with fluoride concentration. The fluoride concentration is high (1.58 –11.6 mg/L) in 18 out of 29 groundwater samples analysed. The regression equations were developed by taking Fluoride as dependent variable and other water quality parameters as independent variables. Compared to other parameters total hardness and chloride indicate stronger relation

Keywords: Fluoride, Fluorosis, pH, dissociation of fluoride, geological strata.
