目的：了解天河区生活饮用水水质基本状况，为提高本区水质，促进群众健康提供科学依据。方法收集天河区2008~2012年共1165份生活饮用水水质检测资料，依照国家标准GB5749-2006对检测结果进行评价分析。结果天河区生活饮用水5年总合格率为75.5%，2008~2012年合格率分别为56.1%、70.0%、78.9%、84.4%、79.4%，5年间合格率有显著差异（χ2=31.2，P<0.05）。所有检测项目中，微生物检测项目菌落总数、总大肠菌群合格率最低，分别为84.1%、96.4%。结论天河区生活饮用水水质在过去5年中有显著改善，但仍有进一步提高的空间，微生物污染是本区水质防治重点，需加强监督监测和消毒工作，保障本区人民饮水健康。

Objective:To learn the basic conditions of Tianhe drinking water quality and provide the scientific evidence for improving the water quality and promoting the people's health. Methods:1165 water samples were col ected, tested, evaluated and analyzed according to GB5749-2006"drinking water health standards". Results:The total passing rate of Tianhe is 75.5%. From 2008 to 2012, the passing rate was respectively 56.1%, 70.0%, 78.9%, 84.4% and 79.4%, there was significant dif erence among five years. In al the detection items , total number of bacterial colony, coliform bacteria had the lowest passing rates and the rate was 84.1%, 96.4%. Conclusion:Tianhe district drinking water quality had been obviously improved since 2008, but we need make further ef orts to raise the passing rate. In order to make Tianhe's people drink the safe water, we should enhance water quality monitoring work to eliminate microbial contamination.
