Abstract Shouguang was once the key area of preventing endemic fluorine disease in Shandong Province. Based on field survey and soil and water sample test, this paper summarizes the distribution of fluorine disease area and geochemical environment characteristics and studies the relationship between fluorine disease and geochemical environments such as lithologic character, soil, terrain, shallow groundwater and water for human living. On the basis of systematic environment geochemical survey, the cause of high-fluorine groundwater was studied. It is considered that rock, soil and seawater constitute the main sources of high-fluorine groundwater. There probably exist two patterns for the formation of high-fluorine shallow groundwater, seawater invasion enrichment and evaporation concentration. The factors and processes of fluorine enrichment in groundwater are studied and the preventing measures are proposed.
