Indication of Hydrochemistry and Isotope for Vertical Circulation of Groundwater in the North China Plain
On the basis of a full analysis of the hydrogeological conditions of the study area, the hydrochemistry and isotopic compositions of groundwater in the different water-bearing strata and different times were revealed in the Bailing experiment process. The vertical cyclical characteristics of groundwater were explored. The results show that the groundwater can be divided into three types in the study area; with increasing depth the water quality becomes better, salinity reduces and hardness decreases.
