2020年兴化市生活饮用水污染卫生监测结果分析

Analysis of Health Monitoring Results of Drinking Water Pollution in Xinghua City in 2020

目的分析2020年1—12月兴化市生活饮用水污染卫生监测结果。方法江苏省兴化市疾病预防控制中心2020年1—12月以兴化市辖区内所有乡镇及街道为检测范围,设置监测点,获取城市及农村饮用水水样总数248份,针对污染卫生监测结果做详细分析。结果农村人口及城市人口占比分别为49.01%、50.99%;城市饮用水水样检测合格率(包含市政供水及二次供水)为100%,农村集中式供水水样(包含枯水期及丰水期的出厂水及末梢水样)的合格率为100%;针对城区自来水末梢监测点,项目合格率高达92.86%。结论农村与城市人口各约占兴化市总人口一半,于2020年中的农村及城市用水的水样检测结果均为100%合格,城区自来水末梢检测可见含氧量不足及浑浊度过高等问题,且此次污染主要波及了兴化市自来水厂以及兴化市第二自来水厂。
