摘　　要：目的全面了解宁海县农村水站水质卫生现状,摸清村级规模水站客观存在的风险隐患,最大程度保证我县广大农村生活用水安全,为我县农村水站改造,水质达标提升工程提供科学依据。方法设立东、南、西、北、中301个农村水站集中式采样点。按照《生活饮用水标准检验方法》(GB 5750—2006)进行采集和检测,依据《生活饮用水卫生标准》(GB 5749—2006)进行分析和评价。结果于2019年—2022年随机采集水样1650份,水样合格份数为224份、总合格率13.58%(224/1650),其中2019年合格率33.10%(139/420)、2020年合格率18.49%(71/384)、2021年合格率1.69%(8/474)、2022年合格率1.61%(6/372)。不合格的主要因素是细菌学指标合格率低,水源水与出厂水合格率比较差异无统计学意义(P>0.05)。结论宁海县农村水站水质检测合格率较低,以微生物超标为主,提示饮用水存在安全隐患。针对本县农村水站水质卫生现状存在的问题应及时开展对策研究,适时加强对农村水站水源水质保护与管理,采取措施着力完善水质净化和消毒措施,建立水质定期检测机制,优化改造农村小型水站,着力构建城乡同质共享的一体化、规模化供水新格局,逐步实现城乡居民同质饮水。Objective This paper aims to comprehensively understand the present status of water quality and sanitation of rural water stations in Ninghai County,get clear picture of the objective risks and hidden dangers of village-level water stations,so as to guarantee the safety of domestic water in rural areas of our county to the largest extent,as well as to provide scientific basis for the reconstruction of rural water stations and the improvement of water quality standards in Ninghai county.Methods A total of 301 centralized sampling points of rural water stations were established in east,south,west,north and middle.Collec⁃tion and test were conducted according to Standard Test Method for Drinking Water(GB5750-2006),in which analysis and evaluation were conducted according to Standards for Drinking Water Quality(GB5749-2006).Results A total of 1650 water samples were randomly collected from 2019 to 2022,in which 224 water samples were qualified,with a total qualified rate of 13.58%(224/1650),the qualification rate in 2019 reached 33.10%(139/420),18.49%(71/384)in 2020,1.69%in 2021(8/474);the passing rate was 1.61%(6/372)in 2022.The main factor of disqualification was the low qualified rate of bacteriological index.There was no statistical significance on the difference in the qualified rate between source water and factory water(P>0.05).Conclusion The qualified rate of water quality test in rural water stations of Ninghai County is low,mainly because the microorganisms exceed the standard,indicating that there are hidden dangers in drinking water safety.In view of the problems existing in the current water quality and sanitation of rural water stations in our county,countermeasures should be carried out in a timely manner,the protection and management of the water quality of rural water stations should be strengthened in a timely manner,measures should be taken to improve water purification and disinfection measures,a regular water quality testing mechanism should be established,and rural small water stations should
