UNIVERSITY OF NEWCASTLE UPON TYNE School of Civil Engineering and Geosciences COURSEWORK- CIV702 PROJECT BRIEF ON: ASSESSMENT OF THE RESPONSE OF LATERITIC CLAY COMPONENT OF A LANDFILL LINING SYSTEM TO EXPOSURE TO LANDFILL LEACHATES BY: Mr Godwin Eton Department of Engineering Geology A59089203 1.0 INTRODUCTION 1.1 Statement of the Research Problem Solid wastes comprising refuse, garbage, sludge, slurries, etc. are unwanted heterogeneous materials, residue from domestic (household etc.), commercial, industrial and agricultural activities (Leton, 1990). Disposal of solid waste could be by pre-treatment, incineration, composting, landfill or any desirable combination of them (Leton & Omotosho, 2004). Landfill is by far the cheapest known method of final disposal of solid waste. One very undesirable by-product of landfill operation is the leachate or contaminated water produced by rainfall on the surface of waste which percolates, picking up and/or dissolving soluble material pollutants-organic, inorganic, etc. If unchecked, leachate seriously pollutes natural water sources. To prevent this pollutants from contaminating the ground water system below...
