摘要
目的分析安源区2020年城镇、农村生活饮用水水质监测结果与影响水质的相关因素,为城乡居民的饮水安全管理提供科学依据。方法从2020年5月下旬到10月底,在丰水期、枯水期共收集农村与城区96份水样,进行水质监测,统计分析2020年安源区城乡生活饮用水水质监测结果与影响水质的有关因素。结果42个农饮水采集点共采集水样84份,而6个城区饮用水采集点共采集水样12份;检测结果显示,城区饮用水水质检测总合格率为100%(12/12),农村饮用水水质检测总合格率为80.95%(68/84);城区饮用水水质检测总合格率与农村饮用水水质检测总合格率相比,差异无统计学意义(χ^(2)=1.543,P=0.214)。城区出厂水、末梢水、二次供水的合格率均为100%,而农村的出厂水检测合格率为100%,末梢水检测合格率为66.67%(32/48);丰水期、枯水期,城区的出厂水、末梢水、二次供水的合格率均为100%,而农村在丰水期、枯水期的出厂水检测合格率为100%,但末梢水在丰水期的检测合格率为33.33%(8/24),与枯水期比较差异有统计学意义(χ^(2)=7.35,P=0.007);丰水期时,农村生活饮用水31项检测指标中,除硝酸盐氮(95.83%)、总大肠菌群(37.5%)、游离氯(37.5%)三项外,其余指标检测合格率均为100%;枯水期时,农村生活饮用水的31项指标检测合格率均为100%。结论2020年安源区的城乡生活饮用水水质情况总体较好,而游离氯缺乏与微生物污染为农村生活饮用水水质不合格的主要影响因素,故需加强农村生活饮用水的日常监测与管理工作。
Objective To analyze the monitoring results of urban and rural drinking water quality and the relevant factors affecting water quality in Anyuan District in 2020,so as to provide scientific evidence for the management of drinking water safety of urban and rural residents.Methods A total of 96 water samples from rural and urban areas were collected during the flood season and the dry period from the last ten-day of May to the end of October 2020,and the water qualities of the collected water samples were monitored.The monitoring results of urban and rural drinking water quality and the relevant factors affecting water quality were statistically analyzed in Anyuan District in 2020.Results A total of 84 water samples were collected from 42 agricultural drinking water collection points,while 12 water samples were collected from 6 urban drinking water collection points.The test results showed that the total pass rate of drinking water quality testing in urban areas was 100%(12/12),and the total pass rate of drinking water quality testing in rural areas was 80.95%(68/84).There was no significant difference in the total pass rates of drinking water quality testing between urban areas and rural areas(χ^(2)=1.543,P=0.214).The pass rates of factory water,terminal water,and secondary water supply in urban areas were all 100%,while the pass rate of factory water was 100%,but the pass rate of terminal water was 66.67%(32/48)in rural areas.During the flood period and dry period,the pass rates of factory water,terminal water,and secondary water supply were all 100%in urban areas.The pass rates of factory water in rural areas in the flood period and dry period were both 100%,but the pass rate of terminal water in the flood period was 33.33%(8/24),which was statistically different compared with that in the dryperiod(χ^(2)=7.35,P=0.007).During the flood season,among the 31 detection indexes of rural drinking water,except for nitrate(95.83%),total coliform bacteria(37.5%),and free chlorine(37.5%),the pass rates of other indicators were100%.During the dry period,the pass rates of 31 indicators of rural drinking water were all 100%.Conclusion In 2020,the quality of urban and rural drinking water in Anyuan District is generally good,and free chlorine deficiency and microbial contamination are the main influencing factors of unqualified drinking water quality in rural areas,so it is necessary to strengthen the daily monitoring and management of rural drinking water.
