Analysis of Drinking Water Quality and Sanitation Monitoring Results in a City from 2021 to 2023
Objective:To analyze and discuss the results of sanitary inspection of drinking water quality in a city,providing scientific grounds for reinforcing the management of drinking water safety.Methods:Drink-ing water hygiene monitoring data from both low-flow and high-flow periods between 2021 and 2023 were col-lected and analyzed.Results:The overall compliance rate of drinking water in urban and rural areas from 2021 to 2023 was 90.64%.A statistically significant difference was observed when comparing 2021 with 2023(P<0.05),while no significant differences were found when comparing 2021 with 2022 or 2022 with 2023(P>0.05).The compliance rate during the low-flow period was 85.96%,and during the high-flow period,it was 95.32%,with a statistically significant difference between the two periods(P<0.05).The compliance rate for rural drinking water samples was 83.33%,while that for urban water was 100%,indicating a signifi-cant difference(P<0.05).Factors affecting the compliance rate included total coliforms,Escherichia coli,total bacterial count,physicochemical parameters,and chlorine dioxide,among which the overall compliance rate of physicochemical parameters was significantly higher than that of microbial parameters and chlorine diox-ide.Conclusion:The compliance rate of rural drinking water samples is relatively low,reflecting suboptimal water quality.Although gradual improvements have been observed over time,continued and intensified monito-ring of rural drinking water is necessary to further enhance the quality of drinking water.
