摘要: The Nanjido Landfill is the largest uncontrolled landfill in Korea and it causes various kinds of environmental problems. gases leachate are recognized as most serious problems associated with landfill. This study employs a series numerical models uses test data to interpret distribution flow leachate. Leachate seepage appears about 40–60 m higher than estimated basal groundwater table. Thus, indicate that perched or floating layers formed unsaturated zone production rate using infiltration model for flow. Geochemical degrades quality along downgradient zone. impact on river water estimated.
