Abstract Objective To understand the health risk of drinking water in rural areas of Jinhua and to provide evidence for water sanitary management in rural areas. Methods Totally 2 032 samples of drinking water in rural areas of Jinhua were collected from 2016 to 2018. According to GB/T 5750-2006 Standard Examination Methods for Drinking Water,five chemical carcinogens（As,Cd,Cr6+,CHCl3 and CCl4）and twelve non-carcinogenic chemicals（Pb,Hg,Se、CN-、F-、NO3-、Al、Fe、Mn、Cu、Zn and NH3-N）were detected. The health risk assessment in rural drinking water was conducted by United States Environmental Protection Agency（USEPA）model. Results The total health risk,total carcinogenic risk and total non-carcinogenic risk of rural drinking water caused by the seventeen chemicals were 34.8×10-6/a,34.80×10-6/a and 6.65×10-9/a,respectively. The carcinogenic risk of five chemical carcinogens accounted for 99.98% of the total health risk,and the carcinogenic risk of Cr6+ accounted for 89.95% of the total health risk. The total health risk of the fully processed,partially processed and unprocessed water samples were 31.68×10-6/a,34.78×10-6/a and 34.77×10-6/a,respectively. The total health risk of finished water and peripheral water were 34.79×10-6/a and 34.82×10-6/a. Conclusion The health risk of drinking water in rural areas of Jinhuacaused by chemicals is low. The hexavalent chromium has the highest health risk and need more attention to be paid on.
