Phenol and Chromium Transport from Piuyngan Landfill, Yogyakarta, Indonesia

The groundwater contaminant transport is an important thing to sustain of groundwater resource and reduce the risk of groundwater. Further, those are useful for groundwaterresource management and policy. Piyungan Landfill has been operated since 1995 and is the biggest landfill in Bantul Regency. Day by day the wastes are increasing in Yogyakarta is dumped in Piyungan landfill that can produce leachates which give value of contaminant concentration. According to, the primary result of water quality samplings which measure from leachate to dug well and to river. The result of Cr total resulting was higher than 0.05 mg/l which outcome was among 0.2164 to 0.3885 mg/l. Base on, the water quality resulting which mentioned on upper part, the hypothesis is contaminant are moving from leachate pond, thus this research will do and focus on the contaminant transport map and plum map, to understand the nature of contaminant plume from Piyungan landfill. In order to circumvent, minimize, or mitigate the contaminants in groundwater and the river, the result will be used to carry groundwater contaminant plum map and modeling and plum.
