Numerical modeling of the environment impact of landfill leachate leakage onudgroundwater quality-A field application

摘要

There are more than 372 big uncontrolled landfilludareas in China. Waste disposal facilities are mainlyudresponsible for the gradual quality degradation ofudgroundwater. This paper reports an integrated studyudundertaken to develop an environmental assessment of theuduncontrolled sanitary landfill area of the city of Jiaxing,udZhejiang, China. The USGS modular 3D finite differenceudgroundwater flow model (Mod- flow) and Modular 3D FiniteudDifference Mass Transport Model (MT3D) software wereudused to simulate groundwater flow and contaminantudtransport modeling. The results indicated that landfilludleachate leakage has significant effect on groundwaterudquality.
