Monitoring results of rural drinking water quality in 9 counties of Handan City from 2010-2011

目的了解邯郸市9个县农村饮用水水质现状,为推进农村饮水工程建设提供参考依据。方法对邯郸市9个县264个监测点的农村生活饮水水质进行监测,按GB/T 5750-2006《生活饮用水标准检验方法》要求采样监测,按照GB5749-2006《生活饮用水卫生标准》进行评价。结果 2010—2011年邯郸市9个县生活饮用水感官和一般化学指标超标率为3.9%;毒理学指标超标率为11.2%;污染指标超标率为1.4%;细菌学指标超标率为31.6%;超标率较高的项目主要是菌落总数、总大肠菌群、耐热大肠菌群、氟化物、浑浊度、肉眼可见物、硫酸盐、总硬度等。结论邯郸市9个县农村饮用水水质存在供水消毒处理不到位现状,应采取相应措施对水质进行有效净化消毒、改水降氟,加强集中式供水管理和监督检测,让人们喝上合格的水。

[ Objective ] To understand the current situation of rural drinking water quality in 9 counties of Handan City, provide the evidence for promoting the drinking water project construction in rural area. [ Methods] The rural drinking water quality was moni-tored in 264 monitoring sites of 9 counties in Handan City. The sampling and monitoring were performed according to the Standard examination methods for drinking water （ GB/T 5750-2006 ）, and the results were evaluated based on the Drinking water sanitary standard （ GB 5749-2006 ）. [ Results] During 2010-2011, the over standard rate of sensory and general chemical index was 3.9%, and that of toxicology indexes, pollution indexes and bacteriology indexes was respectively 11.2%, 1.4% and 31.6%. The inde-xes with higher over standard rate mainly included total bacterial count, total coliform group, thermotolerant coliform bacteria, flu- oride, turbidity, visible matter, sulfate, and total hardness. [ Conclusion ] The disinfection treatment of rural drinking water in 9 counties of Handan City is not satisfactory, so it is necessary to carry out relevant measures for effective disinfection and defluorida-tion, strengthen management and supervision of centralized water supply.
