Abstract

In addition to the continuous emission of contaminants into groundwater at the old cemeteries (or landfills), the lack of treatment measures to prevent and decrease the contaminant transport has caused the concerns of the groundwater quality which is beneath these cemeteries. In this paper, according to the main goal is to remove NH₄⁺ arising from the Con Dao cemetery to Pleistocene aquifer of  Con Son Valley, the  in-situ treatment of NH₄⁺ (pump and treat measure) is proposed to apply and the treatment process of NH₄⁺ is sumulated on RT3D code of  GMS 10. The  simulation results show that NH₄⁺ treatment efficiency depends not only on location, quantity and flow rate of the extraction - injection pumps, but also on the fluctuations of  groundwater level, namely the groundwater drawndown.
