摘要:目的 了解广元市城区饮用水水源卫生现状，发现问题并提出建议，更好的保证饮用水卫生安全。方法 对广元市城区5个水厂的水源地进行现场调查，查阅分析西湾水厂水源水质监测报告。结果 调查广元市城区5个以嘉陵江为水源水的水厂，60%的水源地划分明确，按照距离由近及远依次为一级、二级和准水源保护区，明确设立了标志牌，标明地域范围及其禁止进行的活动，并有专人进行定时和不定时巡查，密切监测水源安全状况。80%的水源地周围存在采砂活动，且堆砂较多；另外，80%的水源与高速公路、铁路相互交叉、伴行，时刻面临交通事故特别是危化品的威胁。结论 广元市城区居民生活饮用水水源卫生状况总体上安全，水质良好，但也存在小规模供水水厂水源保护较差，水源保护区划定不规范，无备用水源等问题。

The investigation on drinking water sources' status for urban residents in Guangyuan

Abstract: Objective The aim of this study was to get the information on drinking water sources' status in Guangyuan, to find problems and put forward some feasible suggestions, so as to ensure the safety of drinking water in Guangyuan. Methods The spot investigation on drinking water sources' status in Guangyuan was according to the route from water plants to the water resources. At the same time, the water quality monitoring report of water plant was analyzed and the details were recorded. Results The survey searched five water plants supplying the urban residents' drinking water in Guangyuan. And the five water plants all regarded the Jialing river as source water. 60% of the water source protection areas were divided clearly, and according to the distance, in turn, there were Quasi water source protection zone, primary water source protection area, and secondary water source protection area. 60% clearly established the water resource protection signs, which indicate the regional scope of water source and prohibited activities in water source protection zones. What's more, special personnel always carry out regular and irregular inspections to closely monitor the water security situation. Around 80%, however, had sand mining activities, and the pile of sand was accumulated. In addition, 80% of the water sources were accompanied by the interaction of highway and railway, in order to face the threat of traffic accidents constantly especially hazardous chemicals emergency. Conclusion The drinking water sources' status for urban residents in Guangyuan in general was safe and the water quality was pretty good. But there also existed problems. For example, some small-scale water supply plants was poorer in water source protection, water source reserves' designation was not standard, no alternate water source and so on.
