泰安市地下水污染现状与成因分析

Present Condition and Origin Analysis of Underground Water Pollution in Tai′an City

采用参数分级评分叠加型指数法对泰安市地下水污染现状进行的评价结果显示 ,泰安地下水已遭受严重污染。地下水污染以地下水中宏量组分、NO-3 、硬度、TDS的迅速上升高以及地下水遭受人为环境物质的污染为主要标志 ;地下水污染主要受地下水系统水文地质结构、纳污河流、污水灌溉及地下水开采控制和影响 ,地下水污染是人类活动影响的结果。

As showed by the evluation result by using superimposing index method with a parameter of giving a mark, present condition of underground water pollution in Tai′an city has been polluted badly. Rapid rising of macrocompositions, NO 3-, degree of hardness and TDS, and underground water pollution caused by environmentsal matters are major symbols of underground water pollution. It is controlled and effected by hydro-geological structures, rivers holding dirty matters, useless water irrigation and underground water exploitation. Underground water pollution is the result of human being′s activities.
