High-F Groundwater in Gaomi City-Its Genetic Study

Gaomi City was once a serious fluorine poisoned region.Shallow high-fluorine groundwater was the main cause of endemic fluorosis.On the basis of a systematic environmental geochemical survey,the genesis of local high-fluorine groundwater was studied.The results showed that the rock and soil are the main sources of local shallow groundwater.The factors and process of F enrichment were discussed and the measures of cotrolling high-F groundwater have been put forward.
