宜州市2008年—2013年农村生活饮用水监测结果分析

目的了解宜州市农村居民饮用水状况,为今后改善当地饮用水水质提供科学的依据。方法 2008年—2013年期间在全市16个乡镇随机选择398个取样点采集水样,样品在实验室进行检验和评价。结果 6年共检测集中供水样品796份,总体合格率为36.43%,枯水期与丰水期水质合格率分别为37.69%,35.17%,差异无显著性（P〉0.05）,通过整改后水质的合格率由2008年的13.89%提高到2013年的70.74%。引起水质检测合格率低的主要原因是细菌学指标,当地的江河水、泉水和井水监测合格率均未超过31%。结论宜州市农村居民饮用水质量虽得到不断改善,但饮用水中的细菌学指标合格率仍然是监测和改善的重点。

Analysis of the results of rural water quality monitoring for drinking purposes from year 2008 to 2013 in Yizhou city

The main cause of low water quality testing is qualified bacteriological indicators. Local river water, springs and wells to monitor the pass rate did not exceed 31%.Conclusion The city＇s drinking water has been continuously improving the quality of rural residents, but the passing rate of bacteriological indicators in drinking water is still the focus of the monitoring and improvement.
