Abstract:
Objective:To assess the drinking water quality and its related factors in rural schools in Anhui Province from 2023 to 2025, so as to provide a basis for drinking water management of school.
Methods:From July 2023 to December 2025, a total of 920 drinking water samples from rural schools were collected and tested in all 59 counties in Anhui Province by using stratified random sampling. The results were evaluated based on the Standards for Drinking Water Quality. Chi-square test, Chi-square trend test, and Logistic regression analysis were used for statistical analysis.
Results:From 2023 to 2025,the compliance rates of drinking water quality in rural schools were 79.06%,84.10%,87.15% respectively,with an overall compliance rate of 84.24%. The water quality compliance rate showed an upward trend over the three years ( χ 2 trend =5.99, P <0.05). Conventional treatment was the predominant water supply mode (74.57%), and rural centralized projects accounted for most water supply facilities (83.70%). Univariate analysis indicated that water samples from surface water sources, large scale water plants, municipal water supply, rural centralized water supply projects, conventional treatment processes and plants with sanitary licenses had significantly higher compliance rates ( χ 2=94.52, 74.39, 253.69, 218.34, 113.34，all P <0.05). Multivariate Logistic regression analysis showed that after adjustment for survey year, water supply mode( OR =4.98, 95% CI =2.55-9.75), sanitary license( OR =2.36, 95% CI =1.29-4.31), and water plant type( OR =3.78, 95% CI =2.04-7.03) were factors associated with the compliance rate of drinking water (all P <0.05).
Conclusions:Drinking water quality in rural schools across Anhui Province has improved, but the compliance rates of water samples from supplies with unconventional treatment, self supplied facilities, and supplies without health permits are relatively low. The water treatment of water plants should be improved, sanitation management should be strengthened, so as to ensure the safety of drinking water in schools.
