| dc.description.abstract | The Addis Ababa City Administration started a project to establish a new sanitary landfill site at Chebe Weregenu, which is 26 km from the city center of Addis Ababa. The project feasibility studies were already conducted. It is now under design study phase. In the feasibility studies, one of the main gaps noted was on the permeability of the residual soil, 1.164x10-4 to 2.329x10-4cm/sec which is below the standard. The standard requirement for sanitary landfill should be 1x10-7cm/sec or less. The permeability test result in the present research was found1.897 X10-7 to 1.085x10-8 cm/sec which is within the standard. The other gap was, both studies stated that the existing residual soil 0-5 meters is black cotton soil. In the present research, based on site investigation and test data the residual soil 0-4.5 meters have different soil profiles, black cotton soil and tuff material. The purpose of this research work is to identify possible gaps in the feasibility studies and to conduct geological and environmental appraisal of the Chebe Weregenu Sanitary Landfill Project. Eleven representative soil samples, two rocks and four water samples were collected from the site and were tested for the purpose of geological and environmental appraisal of the landfill site application. All representative soil sample test results complied with the standard requirements of permeability for clay cap and clay liner application. Regarding plasticity, the liquid limit value of seven out of ten samples complied with the standard requirement, but three are above the standard. The water quality test result was found fit for drinking purpose as per WHO standard. The water quality and soil fertility test results are base line data to be used as a reference point during the operational phase. This research filled the gap of the feasibility studies and further established different findings based on the primary data. Those results found within the standard range were presented as acceptable values and those test results out of the range were recommended for further investigation during the design study | en_US |
