Abstract：Objective To monitor and evaluate the environmental health risks of urban drinking water supply sources in Yantai city from 2015 to 2017. Methods From 2015 to 2017, source water monitoring stations of 17 municipal waterworks in Yantai city were monitored. The monitoring frequency was once per quarter, and a total of 204 water samples were detected. Excel 2007 was used for establishing a database, SPSS 17.0 software for statistical analysis, and the environmental health risk assessment model for calculating the total health risk. Results The overall qualified rate of water from the sources of drinking water supply in Yantai was 86.71%. The health risks in descending order were as follows: fluoride, nitrate, manganese, iron, zinc, ammonia-nitrogen (copper, lead, mercury and selenium). The total health risks for adults and children were 23.78×10-6/year and 32.43×10-6/year, respectively, which were caused by non-carcinogenic substances. Conclusions The health risks induced by source water of the municipal waterworks in Yantai city are higher in children than in adults, and all the risks are caused by non-carcinogenic substances. Nitrate and ammonia nitrogen are the main over-standard substances, and the average personal health risk caused by fluoride is high.
