The Relationship between High Fluorine Groundwater and Geological Environment in Gaomi

Drinking fluoride water is the root cause of serious endemic fluorosis in Gaomi. According to the investigation and sampling test, this paper analysis the relationship between high fluoride water and stratigraphic units and topography: in stratigraphic, high fluoride areas, heituhu Formation and the Yihe Formation are consistent; in topography, high fluoride areas and flood plain landscape are matching. Thus we can summarize the conditions for the formation of high fluoride water. Depending on the analysis of the data, this paper points out the relationship between the fluorine and other elements in the water, especially the fluorine’s close relationship with Mg, Se, Sr. Countermeasures Measures and suggestions on fluoride removal are also provided.
