The bioreactor type of landfill is to operate to enhance waste decomposition by continuously supplying water such as leachate and wastewater within the landfill, which helps increase the landfill gas production, which in turn prematurely stabilize the landfill. Recently, the environmental law for the operation of the bioreactor type of landfill has been enacted and thereafter the bioreactor type of landfill has been introduced for the first time in Korea to the SUDOKWON landfill site. In order to properly apply for bioreactor to the landfill, it is necessary to investigate the water distribution inside the landfill so that water recirculation should be optimally allocated with the zone of concern. In this regard, electrical resistivity survey has been suitably performed to delineate the water distribution in the landfill. That is, it has surveyed for long-term of period that the recirculation of leachate has been properly reflected from electrical resistivity within the second landfill of SUDOKWON landfill site. As a result, the electrical resistivity immediately corresponded to the variation of the extent of the seasonal temperature dynamics. From this, a calibratrion could be accomplished by correlating between temperature and electrical resistivity obtained from this study that can be applicable for optimally monitoring to keep the ideal operating condition for the bioreactor type of landfill.
