摘　　要：目的探讨广州市城市生活饮用水水质卫生状况,为改善生活饮用水水质,保障城市居民用水安全提供科学依据。方法对2012年广州市所辖的10个区、2个县级市的集中式供水单位出厂水、管网末梢水、二次供水监测结果进行统计分析。结果出厂水、管网末梢水、二次供水的合格率分别为100%、92.58%和88.98%,主要不合格指标为游离余氯和浑浊度。全年中第二季度的管网末梢水合格率、样品总合格率较低(83.33%、84.21%)。以西江水为水源的I、II、IV水厂的管网末梢水合格率、样品总合格率最高(100%、100%);以东江水为水源的V、VI水厂的合格率最低(81.25%、83.33%)。结论 2012年广州市城市生活饮用水卫生质量总体较好。第二季度合格率及V、VI水厂的合格率较低可能与广州市的雨季变迁规律和东江水系的水质状况有关。Objective To examine the sanitary quality of urban drinking water in Guangzhou City. To provide the scientific basis for improving the quality of drinking water to ensure safe drinking water fur people in Guangzhou. Methods To analyze the monitoring results of the factory water, pipe network peripheral water and the secondary water supplies from the centralized water supply units of ten districts and two county level cities under the jurisdiction of Guangzhou statistically in 2012. Results The qualified rates of factory water, pipe network peripheral water and the secondary water supplies were 100%, 92. 58~/oo and 88. 98%, respectively. The most unqualified indexes were free residual chlorine and turbidity. In the second quarter of the year, both the qualification rate of pipe network peripheral water and the total sample qualification rate were lower （83.33%, 84. 21%）. In addition, the qualification rates of pipe network peripheral water and the total sample qualification rates of the I, II, IV Water Plants sourcing from the Xijiang River were the highest （100 %, 100 %）. However, the qualification rates of the V, VI Water Plants sourcing from the Dongjiang River were the lowest （81.25%, 83.33%）. Conclusion The sanitary quality of urban drinking water in Guangzhou City is better generally. The low qualified rates of water from the second season and V, VI water plants might be associated with the rainy season of Guangzhou or the water quality conditions from the Dongjiang River.
