Results From 2014 to 2022, a total of 1400 water samples were collected and analyzed, of which 856 were qualified, with a total qualified rate of 61.14%. The differences in the pass rates among different years show an upward trend, and the differences were statistically significant (P＜0.05). There was no statistical significance in the qualified rate of different water periods (P＞0.05). The qualified rate of different water supply methods had statistical significance (P＜0.05). The main individual indicators exceeding the standard in each year were fluoride,followed by total coliform, total colony, sulfate, soluble solid and total hardness. Conclusion From 2014 to 2022, the water quality of urban drinking water in a certain city has been improved year by year, but there is a lot of room for improvement.
