目的了解平果县农村生活饮用水水质卫生现状,为农村改水工程规划和管理提供科学依据。方法对2008～2009年平果县农村生活饮用水水质卫生监测结果资料进行统计分析。结果 2008、2009年平果县农村生活饮用水水质合格率分别为18.09%和14.89%,2年平均合格率为16.49%,集中式供水合格率也仅为19.38%,分散式供水没有1份水样合格。不合格指标中,微生物超标率最高,达到83.51%,其中,总大肠菌群和耐热大肠菌群超标严重,超标率分别为76.59%和73.40%,提示平果县农村生活饮用水水质合格率极低,水质受到人畜粪便和生活污水污染严重。结论影响平果县农村生活饮用水水质合格率低的主要原因是微生物污染严重,应加强对饮用水水源卫生防护和水质消毒处理。
Objective To understand the sanitary status of rural drinking water quality in Pingguo County and to provide a scientific basis for the planning and management of rural water diversion project. Methods The data of health monitoring results of rural drinking water quality in Pingguo County from 2008 to 2009 were statistically analyzed.
