成都市新农村社区饮水卫生现况调查

目的了解成都市新农村建设中生活饮用水卫生状况,为新农村建设政策的制订提供科学依据。方法按照分层随机的原则,2007-2009年起在成都市三圈层选取20个已建成的新农村社区作为调查点,开展农村饮用水卫生现状调查。结果调查的20个新农村社区中有18个社区人群饮用集中式供水,占调查人数的99.5%;采用集中式供水的方式均进行了消毒处理,89.47%的供水点投入使用后进行了水质检测。饮用水以地表水为水源的占61.23%,以地下水为水源的占38.77%。水质检测综合合格率为93.10%(27/29),其中达到一级判定标准的占79.31%,达到二级判定标准的占13.79%。结论成都市新农村社区人群的饮用水水质优于前期成都市农村饮用水卫生的调查水平,乡镇集中式供水的水质仅部分达到一级判定标准。建议在成都市建立农村饮用水厂卫生学评价体系。
