摘　　要：目的了解襄阳市2015—2018年农村饮水水质卫生现状,为政府部门改善农村饮水条件提供科学依据。方法收集并分析襄阳市2015—2018年农村饮用水监测数据。结果2015—2018年共采集农村饮用水水样1865例,样本总合格率为90.62%(1690/1865);经卡方检验,不同年度间水样合格率呈整体上升趋势(χ^2=24.750,P<0.05),差异有统计学意义;枯水期合格率(92.21%)大于丰水期合格率(89.09%)(χ^2=5.362,P<0.05),差异有统计学意义;微生物指标合格率最低(93.57%)(χ^2=111.127,P<0.05),差异有统计学意义。结论襄阳市农村饮水改善工作效果显著,但微生物污染仍是其主要问题;应着力改进水质处理工艺,完善消毒净化处理环节,加大水源地保护力度,加强对重点时期(丰水期)和重点指标(微生物指标)的监督监测力度。Objective To understand the current status of rural drinking water quality in Xiangyang City from 2015 to 2018,and to provide a scientific basis for relevant government departments to improve rural drinking water conditions.Methods The monitoring data of rural drinking water in 2015 to 2018 in Xiangyang City was collected and analyzed.Results A total of 1 865 rural drinking water samples were collected in 2015-2018.The total qualification rate of the monitored samples was 90.62%(1 690/1 865).Using Chi-square test,the qualification rate of the water samples showed an overall upward trend in different years(χ^2=24.750,P<0.05).The qualified rate in dry season(92.21%)was significantly higher than that in flood season(89.09%)(χ^2=5.362,P<0.05).The qualified rate of microbiological indicators had the lowest pass rate(93.57%),and the difference was statistically significant(χ^2=111.127,P<0.05).Conclusion The improvement of rural drinking water in Xiangyang City was remarkable,but microbial contamination was still the main problem.Efforts should be made to improve the water treatment process,improve the disinfection and purification treatment,increase the protection of water sources,and strengthen the supervision and monitoring of the key period(abundant water season)and key indicators(microbial indicators).
