摘　　要：目的了解贵阳市农村集中式供水工程不同水源类型与水处理方式对饮用水的影响,分析存在问题及原因,为加强农村集中式供水工程安全监管提供技术支持。方法 2012年2-9月,抽取贵阳市5县(市、区)共183座农村集中式供水工程作为监测点,进行现场调查,并按照《生活饮用水标准检验方法》(GB/T5750-2006)及《生活饮用水卫生标准》(GB/T5749-2006)采集水样,进行饮用水的评价。结果检测水样732份,地下水水源占75.96%,60.66%的饮用水经过处理。结论贵阳市农村集中式供水工程,江河、浅井水为水源的首要选择;水处理方式以完全处理为首要选择;通过净化、消毒饮用水合格率低,需要进一步调研明确。Objective The aim of the study was to assess the influence of different types of water resources and treatments in the centralized water supply projects on the quality of drinking water in rural Guiyang and analyze the underlying problems and causes, so to provide technical references for the reinforcement of safety supervision on the centralized water supply projects. Methods 183 centralized water supply projects in 5 rural counties （cities or districts） in Guiyang were selected as the monitoring sites between February and September of 2012. Field investigations were carried out and drinking water at the monitoring sites were sampled and evaluated in accordance with the Standard Examinations of Drinking Water （GB^5750-2006） and Hygienic Standards for Drinking Water （GB/T5749-2006）. Results Among 732 tested drinking water samples, 75.96% came from underground water and 60.66% had been treated. Conclusion Rivers and shallow wells should be the primary options of water resource and complete treatment should be considered the optimal choice of the treatment of the water in the centralized water supply projects in rural Guiyang. Further investigation and survey are needed to clarify the cause of the poor compliance rate of purified and disinfected wa- ter samples.
