目的了解安徽省农村生活饮用水卫生监测状况,为加强安徽省农村饮用水水质监测提供科学依据。方法按照《全国农村饮水安全工程卫生监测技术方案》的要求选取监测县,根据不同的水源类型、供水方式及水质状况选取监测点,每个监测点在枯水期和丰水期各检测1次,每次采集出厂水、末梢水水样各1份。结果全省2008~2013年农村饮水安全工程共监测水样34 193份,合格水样16 902份,总体水质合格率49.4%。全省农村饮水安全工程总体水质合格率逐年提高,从2008年的30.1%提高到2013年的62.5%(χ2趋势=1017,P<0.001)。枯水期水质合格率显著高于丰水期(χ2=60.00,P<0.001);出厂水水质合格率显著高于末梢水(χ2=24.62,P<0.001);地面水为水源的水质合格率显著高于地下水(χ2=296.99,P<0.001)。监测指标以总大肠菌群合格率最低,其次是耐热大肠菌群、菌落总数。结论安徽省农村饮水安全工程水质合格率偏低,以微生物指标超标率最高,农村饮用水安全存在一定的隐患。
Objective To understand the sanitary monitoring status of drinking water in rural areas in Anhui Province and provide scientific basis for monitoring drinking water quality in rural areas of Anhui Province. Methods The monitoring counties were selected according to the requirements of the national sanitary drinking water project safety monitoring technical scheme. The monitoring points were selected according to different types of water sources, water supply methods and water quality conditions. Each monitoring point was tested once in the dry and wet periods, The second acquisition of factory water, water and water samples of each 1. Results In the whole province, from 2008 to 2013, a total of 34,193 water samples were collected and 16,902 qualified water samples were collected. The overall water quality passing rate was 49.4%. The overall water quality passing rate of rural drinking water safety projects in the province increased year by year from 30.1% in 2008 to 62.5% in 2013 (χ2 trend = 1017, P <0.001). The passing rate of water quality in dry season was significantly higher than that in wet season (χ2 = 60.00, P <0.001). The passing rate of factory water quality was significantly higher than that of peripheral water (χ2 = 24.62, P <0.001) In groundwater (χ2 = 296.99, P <0.001). Monitoring indicators to the coliform minimum passing rate, followed by heat-resistant coliforms, the total number of colonies. Conclusion The passing rate of water quality in rural drinking water safety project in Anhui Province is low, with the highest rate of exceeding the standard of microbial indicators and the hidden dangers of drinking water safety in rural areas.
