Monitoring and analysis of bottled drinking natural mineral water and drinking water in some public places in a city

目的对某市瓶装饮用天然矿泉水及部分公共场所饮用净水的检测结果进行统计分析,为生活饮用水卫生质量监督监测提供重点工作方向。方法根据相应的检测标准,于2016年-2017年对某市市售的瓶装饮用天然矿泉水及学校、幼儿园等部分公共场所饮用净水卫生质量进行监督监测,依据相应的卫生标准对检测结果进行评价。结果共检测饮用水样品172件,总体合格率为77.3%,瓶装饮用天然矿泉水及部分公共场所饮用净水合格率分别为92.6%和74.5%;检测样品微生物和理化指标合格率分别为77.3%和99.4%;中小学、幼儿园、机关单位、车站和住宅5类不同公共场所饮用净水微生物指标合格率分别为67.3%、59.4%、82.9%、83.3%和100.0%。结论瓶装饮用天然矿泉水卫生质量较好,部分公共场所饮用净水合格率偏低,其主要原因是微生物指标不合格。建议加强对公共场所饮用净水管理,特别是微生物指标的主动监测。
