Objective To understand the secondary water quality in Xiangcheng District of Zhangzhou City. Methods According to “Hygienic Standard for Domestic Drinking Water” and GB 5750-2006 “Drinking Water Hygienic Standard Test Method” for testing, according to GB 5749-2006 “drinking water health standards” for evaluation. Results A total of 3 598 secondary water supply samples were monitored during 2004-2009, with a passing rate of 87.2%. The passing rates of odor and smell and macroscopic findings were above 99.5%, and the pass rate of pH was over 98.6% Degree and turbidity of 100.0% pass rate, free residual chlorine pass rate of 14.8%, the total number of bacteria passing rate was 94.4%, coliform bacteria passing rate was 97.2%. Conclusion The water quality of secondary water supply in Xiangcheng District of Zhangzhou City is unstable and the free residual chlorine is unqualified.
