Abstract
Rapid population growth and industrialization have led to large quantities of untreated waste being disposed of on land. During the rainy season, this waste mixes with rainwater to form a toxic liquid known as leachate. The leachate percolates downward under gravity, contaminating the soil and groundwater. This contamination adversely affects the geotechnical properties of the soil: interaction with the effluent degrades these properties and can cause cracking, settlement, and heaving of structures built on the soil, and in severe cases may lead to their collapse. There is therefore a need to examine how the nature of the pore fluid affects the geotechnical properties of soil. Leachate may be acidic or alkaline, and it sometimes contains a high salt content. This study therefore investigates the effect of the pore fluid’s nature on the plasticity and compaction characteristics of soil.
