吉林省西部地区地下水越层污染问题现状浅析

Elementary analysis of groundwater transboundary pollution in the western region of Jilin Province

吉林省西部地处松嫩平原腹地,是我国重要的商品粮基地。地下水作为该区的主要用水水源,水质情况直接影响到该区的生产生活及经济发展。目前,该区潜水水质已受到不同程度的污染,深部承压水也因越层污染而受到一定影响。本次研究主要针对吉林西部地下水越层污染现状展开,共计测试水样73组,结果表明,该区第四系泰康组孔隙承压水含水层已受到越层污染影响,样品中氟化物、氨氮、砷、氯化物及铝组分等均超标。

The western part of Jilin Province is located in the hinterland of the Songnen Plain, which is an important commodity grain base in China. Groundwater is the main water source in the area, and the water quality directly affects the production, life and economic development of the area. Currently, the quality of phreatic water in this area has been polluted to varying degrees, and the deep confined water has also been affected due to the transboundary pollution. This study mainly aimed at the current situation of groundwater transboundary pollution in western Jilin Province. A total of 73 groups of water samples were tested, and the results show that the pore confined water aquifer of Quaternary Taikang Formation in the area has been affected by transboundary pollution, and the fluoride, ammonia nitrogen, arsenic, chloride and aluminum components in the samples exceed the standards.
