- Abstract
- The low-temperature thermal water in the Primorye Region of the Far East of Russia is traditionally important for medical purposes. A hydrogeochemical study based on 30 samples, including thermal springs, streams and well water has been carried out in the Goriachii geothermal area. The initial year-round survey on the condition of the spring water and the environment has shown that the thermal water demonstrates slight seasonal variation in chemical composition, but no significant seasonal variation in temperature and discharge. The geochemical testing of the surface stream indicated the influence of the thermal area on the surface water, which is exhibited in the hidden discharge. The testing of the head and mouth of the Teplii spring has shown that the increase in the water temperature has reached 2.5° C for every 700 m distance. Simultaneous, the alkalinity and the mineralization increase by a magnitude of up to 1.5. The concentrations of sulphates and sodium likewise increase, while the concentrations of calcium and magnesium decrease.
