重庆市万州区农村学校自备供水卫生状况分析

目的：了解万州区农村学校自备供水卫生与水质状况，分析其存在安全卫生问题，为政府制订相关政策提供科学依据。方法：于2012年5—6月对万州区30家农村学校自备供水单位卫生管理、设施设备等情况开展现场卫生学调查，对其出厂水进行抽样检验，依据国家GB5749-2006《生活饮用水卫生标准》进行评价。结果：万州区农村学校自备供水出厂水样合格率3．33％（1／30），感官性状与一般化学指标合格率86．67％（26／30），毒理学指标合格率96．67％（29／30），微生物指标合格率10％（3／30），消毒指标合格率仅6．67％（2／30）。结论：万州区农村学校自备供水水质合格率很低，学校供水存在安全隐患。建议政府及相关部门要加以高度重视，各职能部门要切实加强农村学校自备供水监管力度，建立饮用水安全卫生保障机制，着力落实饮用水消毒措施，防止介水疾病的发生，确保农村学校学生身体健康和生命安全。
