摘要
通过历时13年的长春市地下水水质的监测工作,对长春市地下水污染现状及污染趋势作了分析,结果表明,长春市潜水污染重,化学组合中Cl^-、SO_4^(2-)、NO_3^-、COD、总硬度、矿化度在很多地方出现高含量,且上升趋势明显;承压水在市中心集中开采地污染,其它地区尚未污染或污染较轻。并提出五点防止地下水污染的对策性意见。
Through the thirteen years' water quality monitoring in changchun groundwater, the present situation on pollution of the groundwater in Changchun city and its tendency are discussed. The results show that the phreatic water are polluted seriously, and in some places, high total hardness, high intensity of mineralization and high contents of Cl^-, SO_4^(2-), NO_3^- COD are showed with a more serious tendeney. In this paper, five counter measures are proposed to protect from the groundwater pollution.
