Groundwater is one of the natural resources having its application in various fields, which affects its quality. Fluoride-enriched water has become a major public health issue in various parts of the world. The geochemical mechanism of the fluoride enrichment in drinking water needs to be evaluated. Groundwater quality is controlled by rock-water iteraction, residence time of water in aquifers, and anthropogenic factors at many locations. Dissolution of fluorite and fluorapetite minerals in earth & simultaneous precipitation of CaCO3 is considered to be among the mechanisms responsible for it. The simultaneous increase in alkalinity of the water with high fluoride levels must be co-related. Due to Ca2+ and Mg2+in, the hardness of the water is responsible for precipitating fluoride from groundwater. Major geological formations where an excessive concentration of fluoride has been reported are sedimentary rocks and metamorphic granites such as shale, limestone, granite, charnokite, BGC gneiss. Climatic conditions, hydro-geological surroundings, physical factors (temperature and rainfall), geochemical processes such as weathering, evaporation, dissolution, and ion exchange are the prominent causes for the elevated concentration of fluoride in aqueous solutions.
