Objective To understand the sanitary status of drinking water quality in Jurong City and provide a scientific basis for further improvement of water quality. Methods According to the requirements of GB 5750-2006 “Test Method of Sanitary Standard of Drinking Water”, sampling was carried out and evaluated according to GB 5749-2006 “Sanitary Standard for Domestic Drinking Water”. Results A total of 2 883 water samples were collected from 2010 to 2013, with a total pass rate of 51.47%. The annual pass rates were 32.56%, 38.27%, 77.76% and 83.11%, respectively. There was a significant difference between years (χ2 = 564.946, P <0.01). The passing rate of factory water was 56.84%, the qualified rate of peripheral water was 48.89%. The qualified rate of municipal water supply, township water supply and regional water supply were 93.72%, 36.62% and 81.20% respectively. The passing rates of municipal waterworks and regional water supply were all higher than those of township waterworks. Conclusion The qualified rate of rural drinking water in Jurong City is relatively low. It is suggested to strengthen the regulation and health management of water supply in rural centralized water supply, strengthen the management of water supply pipelines and continue to promote regional water supply and ensure the safety of drinking water.
