Objective To understand the basic situation of urban drinking water quality in Ningde,and to provide reference for improving the quality of urban drinking water. Methods The monitoring results of urban drinking water in Ningde from 2020 to 2023 were collected,the qualification rate was calculated.SPSS 17.0 was used to conduct statistical analysis. Results The qualified rate of urban drinking water in Ningde from 2020 to 2023 was 93.07% (1 988/2 136),with qualified rates of 90.26% (482/534),90.26% (482/534),95.96% (511/534) and 96.07% (513/534),respectively,showed an increasing trend year by year (${X}_{trend}^{2}$=21.601,P<0.001).The pass rates during the dry season and wet season were 94.67% (1 011/1 068) and 91.01% (972/1 068),respectively,with a statistically significant difference (χ²=10.708,P=0.001).The qualified rates of factory water,terminal water and secondary water supply for municipal water supply were 99.04% (103/104),97.24% (1 058/1 088) and 91.59% (806/880),respectively,with statistically significant difference (χ²=36.140,P<0.001).The qualified rates of municipal water supply and self-built facility water supply (terminal water) were 94.93% (1 967/2 072) and 32.81% (21/64),respectively,with statistically significant difference (χ²=361.926,P<0.001).The main unqualified indicators were disinfectant indicators,turbidity,total coliform bacteria,heat-resistant coliform bacteria,and Escherichia coli. Conclusion The qualified rate of urban drinking water in Ningde is relatively high,but the qualified rate of secondary water supply in municipal water supply and self-built facility water supply is low.Relevant departments need to strengthen supervision,improve the quality of urban drinking water,and ensure the safety of residents' drinking water.
