摘要

本研究考察了瓦查河阶地冲积含水层复合体中地下水污染引起的问题。考虑了两个可行的假设。在第一种情况下,人们普遍认为弱透水层在区域上具有良好的可持续性,并限制了锰污染水向下层含水层的渗透。在第二种情况下,假设弱透水层中存在水文地质窗口,通过该窗口,两个含水层之间可以进行积极的物质交换,并且在开始开采后,抽水井中可以出现锰。

Hydrogeological models for the conditions causing the occurrence of manganese in wells for groundwater extraction from the terrace of the Vacha River, Southern Bulgaria
The presented study examines the problem caused by the groundwater pollution in the alluvial aquifer complex formed in the terrace of the Vacha River. Two working hypotheses are considered. In the first one is accepted that the aquitard is regionally well sustained and limits the penetration of Mn-contaminated waters into the lower aquifer. In the second one is assumed that there are hydrogeological windows in the aquitard, through which active mass exchange between the two aquifers can take place and manganese can occur in the pumping wells after their exploitation is started.
