Objective To monitor the sanitary status of drinking water quality and provide a scientific basis for ensuring the hygiene and safety of drinking water. Methods The factory water and some peripheral water of 12 centralized water supply units in Jiangsu Province were selected for monitoring. The monitoring indicators were 106 full analyzes. Results From 2012 to 2014, 79 total samples were analyzed. A total of 4 samples were unqualified with a pass rate of 94.9%. Unqualified items are conventional indicators, respectively, the total coliform bacteria, the total number of colonies and zinc, the passing rate of 96.2%, 98.7% and 98.7%. Aluminum (55%), oxygen consumption (56%) and fluoride (56%) are the common indicators with the risk exceeding 50%. Conclusion Conventional 42 indicators can basically reflect the health status of water quality and provide a scientific basis for people’s safe drinking water.
