OBJECTIVE: To investigate and understand the sanitary status of drinking water in Wusu City and provide the basis for water diversion to ensure the general public’s health. Methods: Sixteen water diversion projects and three decentralized water supply were monitored each year. The test was conducted in accordance with the “Standard Test Method for Domestic Drinking Water” (GB5750-2006) and the result of GB5749-2006 evaluation. Results: A total of 280 samples were tested in 4 years with a total pass rate of 61.1%. Among the unqualified items, the arsenic constituent ratio was the highest (25.2%), followed by the total number of colonies (19.9%), total coliforms (19.4%), heat-resistant coliforms (11.2%) and pH (10.7%). Unqualified projects, the distribution of indicators of microbial wide area. Arsenic, fluoride mainly in the northern part of Wusu. Conclusion: The water quality and sanitary conditions in Wusu City are not optimistic, hoping to arouse the attention of water conservancy department. Further improve water diversion work and speed up grid-connected projects for small centralized water supply and decentralized water supply.
