Abstract Recharge sources of the phreatic and surface water in the Sule River Valley have been investigated with hydrological, geochemical and isotopic techniques. Stable isotope compositions of shallow groundwater and surface water in the valley evolve from a starting composition which is more depleted. Waters in the valley and surface water in adjacent areas appear unconnected based on chemical composition and radiocarbon activities. Hydrogeological evidence points toward the Qilian Mountain as a recharge zone, which is consistent with the tracer results. The concentration of Tritium is very low, indicating that the age of the shallow groundwater is very old. The results also reveal that the water resources are very sensitive to the environment, which is relevant for the resources management in this ecologically sensitive area.
