solid waste disposal is a huge problem that different cities face due to low soil availability. Additionally, incorrect management and control practices in some landfills means they become potential sources of hydrogeological and environmental contamination due to the risk associated with leachates percolating the ground and reaching the groundwater, which is a toxic hazard. Urban solid waste management is, nowadays, an important global environmental, economic, and social problem as solid waste is growing faster than the global population. Therefore, leachates are an important problem; thus, evaluation and risk management is essential. If good leachate management practices such as proper collection of solid waste, isolated storage sites, suitable treatments, and controlled shedding are not applied in landfills, they will become a potential contamination source that threatens the soil as well as shallow and underground waters. As such, there is a clear importance to control the compacted soil layers in order to prevent the advance of contamination fronts as well as the effect caused by leachates in the geotechnical properties of the soil exposed to these contaminants. This research studies the change of certain geotechnical properties of a soil sample that has been subjected to the effect of solid waste leachates in the field as well as a soil sample subjected to leachates in the laboratory. This methodology allows us, in the laboratory, to deduce possible property variations such as the void ratio, structure, chemistry, shearing resistance, consolidation, and suction of the soils that were exposed to leachates from no-controlled landfills in the field.
