Abstract: Currently, the landfill is a major method for the municipal soil waste disposal. The disadvantage aspects of the solid disposals become more and more prominent. One of the disadvantage is that the landfill leachate liquid accumulated at the bottom of the landfill will cause a serious pollution of the groundwater system. This paper presents the groundwater pollution evaluation results of Jinkou Landfill in Wuhan City. The groundwater at different depths underneath the landfill was sampled and analyzed. The results indicate that the groundwater system is polluted at the upper 50 meter below the ground surface. The upper perched water system is polluted by the ammonia nitrogen and the chloride compounds, and no other chemicals are detected. The lower artesian groundwater system has not been affected by the landfill leachate.

Key words: Municipal Landfills, Landfill Leachate, Groundwater Quality, Contamination
