Problem statement: Hangjiahu regions belong to the Yangtze River Delta region in Zhejiang Province in China. The vast majority of this region is flat, so surface and groundwater both have a low flow rate. With the rapid economic development of the area, a large number of industrial and domestic garbage are generated. These landfill or garbage are exposed and stacked. Because of mismanagement of environment, the atmosphere under the leaching rainfall, results in harmful gases and leachate. A serious pollution of the atmosphere surrounding the dump, soil, surface water and groundwater occurred. By studying the area under different hydro geological conditions this groundwater pollution due to the landfill can be stopped and prevented. This research can also provide a scientific basis. Approach: Some samples were taken to some specific sampling points in order to do chemical analysis. A hydro geological investigation was done on the study area. By using all these data, groundwater pollution was evaluated and predicted through numerical simulation software: Groundwater Modeling System (GMS), from 2006-2007. Results: A total of six main organic pollutants were found in the entire study area including: toluene, dichloropropane, benzene, dichloroethane, chloroform and dichloromethane. There concentration increased form 2006 to 2007 and is higher in surface water than groundwater. Conclusion/Recommendations: Experimental and simulation results were compared and showed that close agreement between these two values were obtained. The application of ecological methods to remove harmful substances such as the cultivation of suitable plants is also necessary
