Abstract

This research focuses on investigation of geological and geotechnical information that will aid the construction of the proposed FUTA waste containment facility (landfill) before the design, development, and construction due to non or inaccurately conducted geological and geotechnical investigation of selected land area used for solid waste disposal. The proposed landfill site is 4,795 m2 of FUTA municipal solid waste. Evaluation of the suitability for the construction of an engineered landfill was determined with geological, geophysical and geotechnical investigation. Geological test was carried out using previous study of the area. The geophysical investigation of Vertical Electrical Sounding and Electrical Resistivity Sounding method were carried out. Disturbed samples were taken at depths of 0.5 and 1.0m respectively with moisture content ranging from 14.20% to 23.40% for 0 – 0.5m depths, 16.20% to 20.40% for 0.5 to 1.0m, specific gravity. The Plastic Index (PI) for samples at depth 0.0-0.5m ranges from 10.9% to 13.2 while the Plastic Index (PI) for samples at depth 0.5-1.0m ranges from 11.1% to 15.3%. The Maximum Dry Density (MDD) for 0.0 – 0.5m depth ranges from 1.68 g/m3 to 1.78 g/m3 and the optimum moisture content ranges from 11.3 g/m3- 15.7g/m3 while the Maximum Dry Density (MDD) for 0.5m - 1.0m depth ranges from 1.68g/m3 to 1.83g/m3 and the optimum moisture content ranges from 13g/m3 to 19g/m3. The coefficient of permeability for 0.0 - 0.5m depth ranges from 2.82E-04 to 4.92E-04 and ranges from 5.43E-04 to 9.11E-04 for 0.5 - 1.0m depth. The soil samples were classified to be A-4 and Silty Clay using AASHTO and USCS methods respectively. The result concluded that proposed area based on the geophysical and geotechnical investigations is suitable for the construction of engineered landfill.
