• 摘要：本文根据河水与地下水中共存污染物、水位同步观测数据、河水断面流量以及水文地质勘探试验等资料,探讨浑河河水对地下水产生次生污染的程度、范围和机理。 浑河河水对两侧地下水造成次生污染。在横向上,近河床污染重,远离河床则逐渐减轻;纵向上,上游重于下游。其污染范围,在地下水连续开采区,大致在离河床800m左右宽度范围内;在非开采区,仅限于百米范围内。

• Abstract：This article is written based on information of common major contaminants of river water and ground water, synchronized observation data of water level, river water flow, and data of hydrogeology survey, in order to find extent, range and mechanism of secondary pollution by the seriously polluted Hun River upon ground water.The results show: on extent of secondary pollution on both sides of ground water effected by Hun River, there is such a pattern that latitudi-nally the closer it is to the river bed, the more serious is the pollution; the farther it is to the river bed, the less is pollution. And, longitudinally the upper stream is more serious than the lower one. The polluted width is within 800 meters from river bed in continuous ground water extraction area, and is limited within 100 meters in nonextraction area.
