The development of conceptual geochemical models is enhanced by saturation index calculations that can identify the equilibrium state of minerals. Speciation modeling provides saturation indices that indicate reactions thermodynamically possible, minerals dissolving and precipitating in an aquifer system. In the present study, aqueous speciation modeling is carried out for the high fluoride groundwaters of some monitoring wells in Uttar Pradesh, Haryana, Rajasthan, Gujarat and Orissa using PHREEQC geochemical code. Speciation modeling results indicate that the groundwaters are oversaturated with calcite and undersaturated with fluorite and oversaturated with fluorite for some monitoring wells in Rajasthan, Orissa and Haryana districts.
