Fluorine concentrations in drinking water in Northern China often exceed standard levels recommended by National Standards for Drinking Water Quality (approximately 0.5~1.0 mg/L).And fluorosis became one of common disease of the local residents. This paper introduces the basic situation of fluorine pollution in drinking water and the main reasons of excess fluorine in Northern China, the local arid to semi-arid climate and strong evaporation lead to fluorine concentration of groundwater. The thesis also analyzes the correlation between fluoride content in drinking water and the local prevalence of endemic fluorosis, it has obvious relationship between fluorosis and fluoride content in drinking water in this area, and cases generally increased along with the growth of age. Besides, the paper puts forward some practical approaches to prevent the local fluorosis as follows, using deep well water instead of shallow well water as the source of drinking water, for the deep well water of high fluorine content, it needs to take corresponding measures to reduce fluorine and to improve drinking water.
