2018年成都市金堂县“7·11”洪灾后生活饮用水应急监测
|
摘要
目的掌握灾后生活饮用水安全现状,及时进行干预,保障生活饮用水安全。方法对金堂县受灾的城区及6个乡镇供水进行应急监测,所采水样按照《生活饮用水标准检验方法》(GB/T 5750.12-2006)检测,结果依据《生活饮用水卫生标准》(GB 5749-2006)判定。结果共采集171个水样,总体合格率为90.6%,其中分散式供水最低(62.5%),不同供水类型间合格率差异有统计学意义(P<0.01);灾后管网水总大肠菌群、分散式供水浑浊度和细菌总数合格率降低,且差异有统计学意义(P<0.05)。结论洪灾对生活饮用水水质影响较大,及时并持续开展灾后生活饮用水监测,对确保灾区生活饮用水安全有重要意义。
Objective To investigate the safety of drinking water after a flood and provide scientific advice for intervention and health education. Methods Emergency surveillance of drinking water in all the flooded towns and villages was performed by analyzing water samples according to Standards for drinking water quality-test methods(GB/T 5750.12-2006) and the results were evaluated according to the Standards for drinking water quality(GB 5749-2006). Results A total of 171 drinking water samples were analyzed, and the overall conformity rats was 90.6%. The conformity rate of non-central-supply water was the lowest(62.5%). Differences in conformity rate were statistically significant among different water supply types(P<0.01). The conformity rates of total coliforms of network water and the turbidity and total bacteria of non-central-supply water decreased after the flood,and the differences were statistically significant(P<0.05). Conclusion Flood could significantly affect quality of drinking water. Timely and continuous surveillance is very important for ensuring safety of drinking water after floods.
