The analysis of microorganism results of rural drinking water in Pinggu District,of Beijing city form during 2012-2014

目的了解北京市平谷区2012-2014年农村生活饮用水微生物污染状况,为提供疾病发生的相关线索和生活饮用水质量提供参考依据。方法依据《生活饮用水标准检测方法》(GB/T 5750-2006)对水质进行检测,依据《生活饮用水卫生标准》(GB 5749-2006)对结果数据进行评价。结果 2012-2014年共监测717份生活饮用水,3项微生物指标综合合格率为72.52%,差异无统计学意义(χ2=4.382,P>0.05),枯水期与丰水期生活饮用水微生物指标合格率差异有统计学意义(χ2=31.803,P<0.01)。结论北京市平谷区农村生活饮用水存在微生物污染情况,政府应加大对农村生活饮用水的防护力度,特别加强对丰水期生活饮用水的卫生监督监测,确保人民群众的饮水安全。
