目的了解信阳市农村饮用水卫生质量状况,为相关部门制定农村改水措施提供科学依据。方法按照《生活饮用水标准检验方法》(GB/T 5750-2006)进行水样采集、保存与检测,按照《生活饮用水卫生标准》(GB 5749-2006)进行评价。结果 2011年共检测农村饮水416份,合格297份,合格率71.39%;其中枯水期210份,合格175份,合格率83.33%;丰水期206份,合格122份,合格率59.22%;枯水期水质与丰水期水质差异有统计学意义(χ2=29.599,P<0.01);不同水源类型水质合格率之间差异有统计学意义(χ2=58.418,P<0.01)。结论信阳市农村饮用水水质总体情况良好,相关部门仍需加强监测与管理。
Objective To understand the sanitary quality status of rural drinking water in Xinyang City and to provide a scientific basis for the relevant departments to formulate rural water diversion measures. Methods According to “Standard Test Method for Domestic Drinking Water” (GB / T 5750-2006), water samples were collected, stored and tested, and evaluated in accordance with “Sanitary Standard for Drinking Water” (GB 5749-2006).

Among them, 210 were in dry season and 175 were qualified, with a pass rate of 83.33%; 206 were wet season, 122 were qualified with a pass rate of 59.22% (Χ2 = 29.599, P <0.01). There was a significant difference in the qualified rate of water quality between different water sources (χ2 = 58.418, P <0.01). Conclusion The water quality of rural drinking water in Xinyang City is generally good, and relevant departments still need to strengthen the monitoring and management.
