This study is focused on the groundwater system of the Rashche Spring which serves as the main source of drinking water for the City of Skopje, located at the foot of the widely karstified Zeden massif. Investigations were made to define the mechanisms of groundwater recharge and its residence time. This was done using isotope tracers including ¹H,...

... Peng Wang studied the geochemical properties of hydrothermal fluid in the MGF system, revealed the source of solute, and determined the equilibrium temperature to supply the reservoir [12]. Using the accumulation rate of 228 Ra in the Dead Sea, Yael Kiro calculated the age and flow rate of high saline water entering groundwater in the Dead Sea [13]. Xianchun Tang analyzed the relationship between the thermal structure, hydrothermal activity, and geothermal dynamics of ETGB by using helium isotope, gravity and magnetism, and seismic data. ...
In recent years, the lake area of the Chahannur Basin has been decreasing, leading to an increase in salt dust storms. In order to find out the recharge mechanism of groundwater in the Chahannur Basin, a total of 51 groundwater and surface water samples were collected. Tritium (3H) isotope and Freon (CFCs) were used to estimate the age of groundwater and preliminarily analyze the sources of groundwater recharge. The characteristics of hydrogen, oxygen, and strontium isotopes are used to indicate the characteristics of the water cycle in the Chahannur Basin. The results show that: (1) Two dating methods, tritium isotope (3H) and Freon (CFCs), are suitable for semi-quantitative dating of groundwater in the Chahannur Basin. (2) Hydrogen, oxygen, and strontium isotopes can be used to characterize the groundwater cycle in the Chahannur Basin. (3) The groundwater level around the Chahannur Lake area is low, and the groundwater in the Chahannur Basin flows from the southwest and northwest to the lake area. (4) The groundwater in the Chahannur Basin is mainly replenished by atmospheric precipitation, and the evaporation of groundwater and surface water is strong. The research results provide a basis for the study of measures to prevent the reduction in the Chahannur watershed area.
