摘　　要：目的分析2016-2017年连云港市农村生活饮用水卫生状况和风险特征,为保障农村饮水安全政策的制定和实施提供依据。方法依据《生活饮用水标准检验方法》(GB5750-2006)对2 234份农村生活饮用水进行检验、按《生活饮用水卫生标准》(GB5749-2006)进行评价和分析。结果连云港市农村饮用水合格率为79. 54%(1 777/2 234,不含消毒剂指标);四县区合格率有差异,东海县合格率低于其他三县区;地面水和地下水合格率分别为74. 95%(398/531)和80. 9%(1 365/1 687);以微生物指标为判定标准,消毒农村饮用水合格率高于未消毒农村饮用水;小型水厂与非小型水厂合格率无差异,以地面水为水源的非小型水厂合格率高于小型水厂;微生物指标占不合格指标的56. 88%(591/1 039)。结论连云港市农村饮用水以地表水为水源地区合格率较低,微生物污染形势严峻,需要加强农村供水设施的建设和管理、完善和规范净化消毒措施,保障农村居民饮水安全。Objective To learn the hygienic status and risk characteristics of rural drinking water in Lianyungang city,2016-2017,and to provide a basis for the formulation and implementation of the rural drinking water safety policy.

The qualified rates of surface water and ground water were 74. 95%( 398/531) and 80. 9%( 1365/1687),respectively. The qualified rate of disinfected rural drinking water was significantly higher than that of un-disinfected rural drinking water, under the Microorganism index. There was no difference in the qualified rates of small water plants and non-small water plants. The non-small water plants using surface water was significantly higher than small water plants. Microorganism index accounted for56. 88%( 591/1039) of the unqualified index.
