[目的]了解泰安市农村集中式供水卫生状况,为进一步提高农村饮用水质量提供依据。[方法]2008~2010年对泰安市辖区内农村集中式供水进行卫生学调查,并于丰水期抽取6个县(市、区)集中式供水点的末梢水水样进行水质检测。[结果]调查的2 061家农村集中式供水点(厂)中,建有专门房屋的占64.06%;完全处理的占3.45%,只进行消毒处理的占0.24%,无处理措施的占96.31%;均未办理卫生许可证,从业人员未进行健康检查,均无水质化验室。检测481份水样,各项指标均合格的占23.08%。水样合格率,泰山区为36.96%,岱岳区为38.46%,新泰市为10.53%,肥城市为25.86%,宁阳县为13.04%,东平县为27.63%(P<0.01)。检测指标中不合格指标主要是总大肠菌群、耐热大肠菌群、菌落总数、硝酸盐、总硬度,合格率分别为39.50%、51.14%、83.58%、71.31%、87.53%;5份氟化物超标。[结论]泰安市农村集中式供水存在较多的卫生问题,多数受到微生物污染,水质合格率不高。
