Results A total of320 water samples were tested from 2014 to 2018, and the qualified rate was 75.63% in 5 years, which showed an increasing trend( χ^2= 10.81, P<0.05). The qualified rate of drinking water in treated rural schools( 79.41%) was higher than that in untreated rural schools( 68.97%)( χ^2= 4.38, P<0.05).
