Research On The Hydrogeochemical Characteristics Of Shallow Groundwater Of Huaibei Plain In Anhui Province

The shallow groundwater is the main water sources supplied for urban and rural production and living in Huaibei Plain. Affected by natural factors and long-term industrial production and agricultural activities. the quality of the groundwater is gradually becoming worse, and the content of parts of the chemical compositions are more than normal standard, which exerts influence on people's health and forms a threat to safety of the drinking water. Therefore, studying the geochemical characteristics of shallow groundwater is of great significance for how to use it. to protect it and to restore it from contaminated status.Based on a lot of references about geochemistry and collecting shallow groundwater samples, the hydro-geological characteristics in Huaibei Plain and spatial distributions of the chemical compositions are studied. The relationships among the macro elements, micro elements and other components are analyzed by statistical methods, and the principal component analytical method is utilized to reveal the relationship between the ionic composition and influencing factors.After analyzing the spatial differences of heavy metals, fitting models are established. Besides, the distribution characteristics of fluoride in shallow groundwater are analyzed and simulated from the mechanism by the way of the experiments. These results provide the scientific evidences for how to exploit groundwater and utilization of groundwater resources, and how to prevent groundwater to be polluted.
