摘　　要：目的:农村饮水水质卫生监测是公共卫生监测体系建设的重要内容之一,通过对水质监测数据进行系统的统计分析,了解农村饮水水质情况并对所出现的问题提出切实可行的解决方法。方法:按照《生活饮用水标准检验法》GB5750-2006各项理化和微生物指标对出水进行卫生学检测,按照农村实施《生活饮用水卫生标准》准则各项理化和微生物指标对农村饮水检测结果进行卫生学评价。结果:2008年的四个区县疾控中心的农村饮用水数据:大部分理化指标符合准则要求,但微生物指标部分存在合格率偏低的情况,菌落总数合格率为90.9%;总大肠菌群合格率为84.3%;耐热大肠菌群合格率为74.4%;游离余氯合格率为62.7%,后三项指标合格率均低于85%。结论:要加强水源水消毒净化处理工作,确保末梢水中所含的游离余氯达到合理水平,使生活饮用水的检测结果符合国家生活饮用水卫生标准,是各个区县管理饮水卫生的重点。Objective：Sanitary monitor of rural drinking water quality is one of the important content which is the establishment of monitoring system of public health.It is important to handle the rural drinking water quality and provide feasible methods to solve the questions occurred.Methods：According to GB5749-2006 Standard for drinking water quality and GB/T5750-2006 Standard examination methods for drinking water,we detect each physi-chemical and microorganic item of rural drinking water set in GB5749-2006 Standard for drinking water quality.And the results are evaluated according to GB5749-2006 Standard for drinking water quality.Results：Bulk physic-chemical items of rural drinking water quality of four regions or counties were qualified,but the qualified rate of microorganic items were prone to low.The qualified rate of total bacterial count was 90.9%,total coli group was 84.3%,thermoresistant coli group was 74.4%,free chlorine residual was 62.7% and the qualified rate of the last three items were all lower than 85%.Conclusion：It is the most important intent of rural drinking water management of each region or county to strengthen defecation and disinfection of source water,to ensure the level of free chlorine residual in tap water to rational level and ensure the rural drinking water quality to meet the national standard for drinking water.
