Indication of hydrochemistry and isotope for vertical circulation of groundwater in the North China Plain

In the North China Plain,a typical area(China Geological Survey Hengshui Hydrogeology Test Facility) was chosen to perform the bailing experiment in different water-bearing strata.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...
