Abstract

Abstract

The groundwater quality parameters determined both at the well head and in the laboratory of Qijia water supply base, Daqing city, differ from what happens in the real situation. Hydrogeochemical method is used to simulate the changes of pH and Eh values due to the inevitable degassing of CO₂ and H₂S resulting from the pressure drop in the course of the groundwater pumping from the water-earing bed to the earth surface. The trends in the groundwater sampling are proposed in the final part of the paper.
