Abstract. Based on monitoring results of 2013–2022, the time-varying ratios of components in mineral water from carbonates containing gypsum and anhydrite are determined, when the activities ratios ²³⁴U/²³⁸U (AR4/8) vary from 11.82 to 15.71. With increasing this indicator, the activity of ²³⁴U (A4) also increases in mineral water, with maxima and minima occurring in 2017–2022. Variations in A4 are consistent with changes in total mineralization, the contents of all macrocomponents (Ca, Na, Mg, Si, K, S, and Cl), and some microcomponents (U, Li, B, V, Mn, Br, Y, Rb, and Sr), with an inverse trends of the other microcomponents (Cu, Sc, Nb, Mo, Ba, Ti, Zr, and Cr). It is inferred that U isotopes vary in mineral water due to changes in the chemical dissolution of carbonates. Mineral water is enriched in ²³⁴U recoil atoms like other dissolving components, whereas OA4/8 is complicated by the dependence of U dissolution on oxidation-reduction potential (ORP).

Keywords: groundwater, Baikal, ²³⁴U/²³⁸U, uranium, active fault, evaporate.
