GROUNDWATER POLLUTION AND ITS GEOCHEMICAL MODELING IN SHIJIAZHUANG CITY

摘要

Groundwater pollution features and its main chemical mechanisms are discussed in the paper. The results of synthetical analysis and geochemical modeling show that the main reason caused groundwater pollution of Shijiazhuang city is the leakage of sewage arid the main chemical mechanism is the dissolution of dolomite and gypsum and the ion exchange of Ca-Na happening in the process of sewage leakage.
