摘　　要：目的 对2022—2023年桂林市农村地区生活饮用水水质情况进行调查,以期为改善桂林市农村地区生活饮用水水质提供依据。方法 回顾性收集2022—2023年桂林市农村区域生活饮用水水质监测数据,了解其不同年份、不同水期、不同水样微生物指标达标情况,并对未达标生活饮用水微生物指标种类进行分析。结果 2022—2023年共检测桂林市农村地区生活饮用水水样650份,2023年桂林市农村地区生活饮用水合格率为69.12%(235/340),低于2022年的80.32%(249/310)。2023年桂林市农村地区生活饮用水总大肠菌群合格率较2022年下降。不同水样类型生活饮用水微生物指标检测合格率存在一定差异,其中井水检测合格率最低。2022—2023年丰水期生活饮用水微生物指标检测整体合格率低于枯水期。结论 桂林市农村地区生活饮用水水质管理取得一定成效,该地区生活饮用水粪便污染较为严重,存在一定肠道传染病风险,且水质受水源、水期影响。应进一步巩固和提升桂林市农村地区生活饮用水水质安全保障和卫生综合治理工作。Objective To investigate the situation of drinking water quality in rural areas of Guilin City from 2022 to 2023,in order to provide a basis for improving the drinking water quality in rural areas of Guilin City.Methods The monitoring data of drinking water quality in rural areas of Guilin City from 2022 to 2023 were retrospectively collected to understand the microbiological indexes reaching the standard in different years,different water periods and different water samples,and the types of microbiological indexes of drinking water that did not reach the standard were ana⁃lyzed.Results A total of 650 drinking water samples were tested in rural areas of Guilin city from 202 to 2023.The qualified rate of drinking water in rural areas of Guilin city in 2023 was 69.12%(235/340),lower than 80.32%(249/310)in 2022.The qualified rate of total coliform in drinking water in rural areas of Guilin in 2023 was lower than that in 2022.There are some differences in the qualified rate of microbial index detection in drinking water of different wa⁃ter sample types,among which the qualified rate of well water detection is the lowest.The overall qualification rate of microbial index detection in drinking water in 2022-2023 was lower than that in dry season.Conclusion The water quality management of drinking water in rural areas of Guilin City has achieved some results.The fecal pollution of drinking water in this area is serious,there is a certain risk of intestinal infectious diseases,and the water quality is af⁃fected by the source and the water period.We should further consolidate and improve the safety of drinking water quality and comprehensive sanitation management in rural areas of Guilin city.
