【 摘 要 】

This study examines the contamination radius that caused by Bakung Landfills and the impact to the surrounding community. The study was carried out based on geological and hydrogeological surveys. Regional geological conditions of this area identified as volcanoclastic rocks. Volcanoclastic rocks are interpreted as the aquifers in this area. This has rock has able to moderately pass the water. It means the leachate from the surface will infiltrate to the subsurface and might cause the contamination of the groundwater system of the study area. The hydrogeological study was carried out by measuring the depth of the bore wells around the study area to identify the groundwater flow in the unconfined aquifer of this area. Hydrogeology study of this areas also gives the information regarding the groundwater levels, which is ranging from 19-66 m below mean sea level. In addition, the direction of groundwater flow from the Northwest direction towards the South-Southeast. This indicates the South - Southeast region will be affected worse than the Northwest region.
