In the paper the author considers the features of chemical composition of the Botchi River basin environmental waters during winter. He shows that river waters recharging from groundwater of volcanogenic formations are characterized by low mineralization (46-56 mg/dm3), bicarbonate-calcium composition, low concentration of potassium ions, chloride and sulfate ions, high content of silicon compounds and mineral phosphorus. Lower levels of mineralization, concentrations of silicon and phosphorus and high concentration of sulphate ion, ammonium nitrogen, dissolved iron and organic matter are revealed in the small rivers water draining modern alluvial deposits. The water in the Botchinsky mineral thermal spring has the temperature 42-44 °C, high pH and mineralization values (> 120 mg/dm3), concentrations of chloride and sulfate ions, silicon compounds, hydrocarbonate-sodium composition and low content of calcium and magnesium ions, ammonium nitrogen and dissolved iron.
