The Kuselyarovskiye mineral springs, which belong to the Yangantau group of mineral waters, are considered. These are self-flowing borehalls with a depth of 33–85.5 m and a flow rate of 4–10 l/s. In addition to the considered springs, there is a formation outlet of subthermal (8.5–18° С) low-flow (0.1–2.0 l/s) springs. The waters are of deep origin, their composition is hydrocarbonate-sulphate-chloride magnesium-sodium-calcium, oxygen-free (O₂ <1 mg/dm³) with mineralization of 1 g/dm³, pH 6.9–7.5, increased content of hydrogen sulphide – up to 9.0 mg/dm³, fluorine – up to 0.92 mg/dm³, radon – up to 2.4 nCi/dm³. In the area of the springs there are significant resources of therapeutic mud, allowing their use for external balneological procedures. Substances with a toxic effect on humans in the waters were not found. Kuselyarovskiye mineral springs are a close analogue of the mineral water "Essentuki no. 1" of the Caucasian mineral waters. In recent years, there has been a deterioration in the balneological factors of the Yangantau sanatorium, located in close proximity to the Kuselyarovskiye springs, the temperature of the gases of Yangantau Mount is decreasing, the geochemical conditions are changing. Kuselyarovskiye springs together with low-radon waters, therapeutic mud and hydrogen sulphide waters can represent an important complex of therapeutic factors for the Yangantau sanatorium and can help preserve the therapeutic factors and increase the balneological resources of the resort. The use of Kuselyarovskie springs with increased fluoride content can help prevent caries, especially in children.
