Abstract

Groundwater in waste landfills can be contarninated by leachates produced from wastes and flow down toward rivers. These accidents are easily discovered in uncontrolled landfill sites. In this study, applications for controlling groundwater pollution and protecting river pollution were studied using installation of cut-off walls around the waste landfill. Analyses for the efficiency and applicability of the cut-off wall were made under environmental, economical anc technical considerations. Cut-off walls were installed at the upgradient and the downgradient. prediction analyses for the hydraulic head distribution over the site were made for concerning with the final cover and without the final cover. Also, the hydraulic head distribution was predicted with well-pumping on both cases, upgradient cut-off wall and downgradient cut-off wall.
