摘要
目的 了解柳州地区2018—2020年农村饮用水水质卫生状况,为政府制定相关政策提供基础数据。方法 收集柳州地区2018—2020年农村饮用水监测数据,并进行统计分析。结果 2018—2020年共采集农村饮用水水样1 877份,样品总合格率为69.26%(1 300/1 877);经卡方检验,不同年度间水样合格率整体呈上升趋势(χ^(2)=39.548,P=0.000),差异有统计学意义;枯水期合格率(63.59%)低于丰水期合格率(75.11%)(χ^(2)=29.240,P=0.000),差异有统计学意义;微生物指标合格率(71.12%)明显低于其他指标合格率(χ^(2)=1.062,P=0.000),差异有统计学意义;出厂水合格率(69.44%)稍高于末梢水合格率(69.03%)(χ^(2)=0.037,P=0.848),差异无统计学意义。结论 微生物污染是柳州地区农村饮用水水质主要的卫生问题,应引起相关部门的重视。
Objective To understand the hygienic status of rural drinking water quality in Liuzhou City from 2018 to 2020,and to provide basic data for the government to formulate relevant policies. Methods The monitoring data of rural drinking water from 2018 to 2020 in Liuzhou City was collected and statistically analyzed. Results A total of 1 877 rural drinking water samples were collected from 2018-2020.The total qualification rate of the monitored samples was 69.26%(1 300/1 877).By chi-square test, the qualification rate of the water samples in different years showed an upward trend(χ^(2)=39.548,P=0.000).The qualification rate in dry season(63.59%) was significantly lower than that in flood season(75.11%)(χ^(2)=29.240,P=0.000).The qualification rate of microbiological indicators(71.12%) was obviously lower than that of other indicators, and the difference was statistically significant(χ^(2)=1.062,P=0.000).The qualification rate of finished water(69.44%) was slightly higher than that of tap water, but the difference was not statistically significant(χ^(2)=0.037,P=0.848). Conclusion Microbial contamination is the main hygienic problem in rural drinking water quality in Liuzhou area, which should be paid attention to by relevant authorities.
