摘要
为了评估内蒙古自治区包头市农村集中式饮用水水源地水质状况和存在的潜在风险,于2015年对包头市农村45个主要集中式饮用水水源地进行调查评估,对其中24个水源地水质进行了抽样监测,分析了农村饮用水源地水质状况、超标原因、饮用水源地保护情况等。调查评价结果显示:对包头市农村集中式水源地环境管理状况评估,发现水源井建设和管理不到位,保护区内存在违章建筑等;抽样监测包头市农村集中式饮用水水源地水质,情况不容乐观,超标污染物主要有总大肠菌群、pH、氨氮、氟化物、硝酸盐氮等,其超标原因主要是:地质条件背景值较高、农村生活源污染等。针对以上农村水源地的水质状况和存在的问题提出对策建议。
In order to assess the water quality and potential risks of rural centralized drinking water sources in Baotou of Inner Mongolia,45 main sources were investigated and evaluated in 2015,among which water quality of 24 sources were sampled and monitored.Their water quality status,reasons for exceeding the standard and current protection situation were analyzed.The results show that the construction and management of water source wells were not very well,and there are illegal buildings in the protected areas,etc.The water quality of the sources is not optimistic.The main pollutants of exceeding the standard are total coliform bacteria,pH,ammonia nitrogen,fluoride,and nitrate nitrogen,etc.The main reasons for exceeding the standard were high background value of geological conditions and pollution of rural living sources,etc.The countermeasures and suggestions had been put forward to improve the drinking water quality and to solve the existing problems.
