Analysis of 106 indexes on 79 drinking-water samples in Jiangsu Province from 2012-2014

目的监测饮用水水质卫生状况,为保障饮用水卫生安全提供科学依据。方法选择江苏省12个集中式供水单位的出厂水及部分末梢水进行监测,监测指标为106项全分析。结果 2012—2014年79份全分析水样,共有4份水样不合格,合格率为94.9%。不合格项均为常规指标,分别为总大肠菌群、菌落总数和锌,合格率为96.2%、98.7%和98.7%。超标风险大于50%的指标有铝(55%)、耗氧量(56%)、氟化物(56%),均为常规指标。结论常规42项指标能够基本反映水质的卫生状况,为民众安全饮水提供科学依据。

[Objectives]To monitor the sanitary situation of drinking water,provide scientific basis for the safety of drinking water.[Methods]The finished water and pipe water from 12 centralized water supply projects in Jiangsu Province were monitored for106 indexes analysis.[Results]Among 79 water samples from 2012-2014,4 samples were unqualified with the qualified rate of94.9%. The unqualified indexes were the regular indexes,including total coli group,total bacterial count and zinc,which the qualified rate was respectively 96.2%,98.7% and 98.7%. The indexes which the risk of exceeding standard was higher than 50%were aluminum（55%）,oxygen consumption（56%）,and fluoride（56%）,which all were regular indexes.[Conclusion]42 regular indexes can reflect the sanitary situation of drinking water and provide scientific basis for the safety of drinking water.
