目的了解地震后江油市生活用水水源的污染状况,为保障生活饮用水卫生安全提供决策依据。方法采用方便抽样方法,采集震后9～25d江油太平镇和三合镇灾民居住点附近的水源水74份进行检测。对14份水质变黑的井水先进行铁和锰检测,再进行全分析。结果抽检水源水总合格率为38.5%,河水合格率为34.4%,井水合格率为57.1%。不合格指标中,大肠菌群、浑浊度占的比重最大。有6份井水中的铁锰超标。结论震后江油太平镇和三合镇的水源水受到较大污染,存在安全隐患,检测结果对灾民安全用水有重要指导意义。 Objective To understand the pollution status of domestic water sources in Jiangyou City after the earthquake and to provide decision-making basis for ensuring the sanitary safety of domestic drinking water. Methods A convenient sampling method was used to detect 74 water sources of water near the settlements in Taiping and Sanhe townships of Jiangyou between 9 and 25 days after the earthquake. Fourteen water blackened wells were tested for iron and manganese prior to full analysis. Results The total qualified rate of tap water was 38.5%, the pass rate of river was 34.4%, and the qualified rate of well water was 57.1%. Unqualified indicators, coliform bacteria, turbidity accounted for the largest proportion. There are 6 wells in the iron and manganese exceeded. Conclusions After the earthquake, the source water in Taiping Town and Sanhe Town of Jiangyou is greatly polluted, which poses potential safety hazard. The test results have important guiding significance for the safe water use of flood victims.
