新疆农村饮用水水质调查与分析

Quality of Drinking Water in Rural Areas of Xinjiang Province

目的了解新疆维吾尔自治区农村生活饮用水水质现状。方法于2009年5-8月,抽取新疆维吾尔自治区38个县(市)采集出厂水和末梢水水样,按照《生活饮用水标准检验方法》(GB/T 5750-2006)进行19个项目检测,并根据《生活饮用水卫生标准》进行评价。结果共采集804份出厂水水样和801份末梢水水样,出厂水平均合格率和末梢水合格率差异无统计学意义(P>0.05)。检测的各项指标中,微生物学指标合格率最低,为76.82%;其次是溶解性总固体,为84.67%。结论新疆维吾尔自治区农村生活饮用水卫生状况不佳,微生物污染是存在的主要卫生问题。

Objectives To investigate the quality of drinking water in rural areas of Xinjiang province.Methods The survey was conducted in 38 counties of Xinjiang Province.A total of 804 treated water samples and 801 terminal tap water samples were selected by random from May to August in 2009.Nineteen items were examined according to the Standard Examination Methods for Drinking Water（GB/T 5750-2006）.The sanitary quality was determined and evaluated according to the Standards for Drinking Water Quality.Results The qualification rate for microorganisms was the lowest（76.82%）,followed by soluble total solids（84.67%）.There was no significant difference on the qualification rate of water samples between treated water and terminal tap water（P0.05）.Conclusions The sanitary status of drinking water was not satisfied in rural areas of Xinjiang province.Microorganism contamination is the main problem in drinking water safety.
