Geoeletrical Monitoring in Nanji Waste Landfill

Nanji Waste Landfill is one of the largest waste disposal site in Korea. The landfill had been dumped without any controls by municipal living wastes and industrial wastes since 1978 to 1992. During the landfilling, there was no controlled procedure to protect contamination of groundwater and soils in the site as well as in the vicinity of the area. The dumped height of landfill is about 90 m and this height is the biggest one of all the waste disposal areas in the world. So the landfill has become a serious social problem. Finally the remedy of the site has been needed to control the highly contaminated groundwater and gas from the landfill and to protect the landsliding for the efficient usage of the site and the vicinity area. This study has been initiated to elucidate the groundwater and subsurface conditions in the landfill.
