[Objective]To understand the hygienic status and quality of self-supplied drinking water in rural schools,so as to provide scientific basis for decision-making by government departments on water improvement.[Methods]In November 2008,a hygienic survey was conducted on self-supplied drinking water in 58 rural schools,and a KAP questionnaire survey was also conducted on water supply conditions and the basic situation of teachers and students,drinking water behavior and sanitation knowledge.[Results]58 school-owned water supplies were surveyed,water covered 35 166 people.In detection of 58 samples of peripheral water,the passing rate was low in pH(the passing rate of 24.14%),total coliform(the pass rate of 75.86%),heat-resistant coliform(the pass rate of 75.86%),total number of bacteria(the pass rate of 67.24%).Peripheral water was 5.18% of total eligible drinking water in 3 608 people qualified,accounting for 10.26%;microbe pass rate 67.24%,drinking water of 27 698 eligible people,accounting for 78.76%;pH value of pass rate 24.14%,drinking water,10 998 eligible,31.27%.The high passing rate of drinking water hygiene,water quality for school students and teachers was 76.03%,the low water quality rate for teachers and students was 67.70%(P0.01).[Conclusion]The passing rate of the water quality of self-supplied drinking water is low in rural schools of Beihai city,the unqualified water samples cover a wide population,and the level of knowledge on drinking water sanitation is not high in the populations.
