Isotopic Age of Groundwater in the Haihe River Plain and Its Regional Hydrogeochemical Distribution Characteristics

This paper presents a preliminary research on the relationship between the formation age of groundwater and its chemical composition established through the evolution of groundwater circulation on the basis of the isotopic age of groundwater and its regional hydrogeochemical characteristics since the Quaternary in the Haihe River Plain. By this research this paper aims to reveal the evolution law of the regeneration ability and utilization of the groundwater resources, thereby providing a scientific basis for the evaluation of groundwater resources.
