Solid waste disposal has become a problem for municipal administrations due to the population growth and the limited availability of land for such uses, furthermore, the increase of rainfall for long periods produces a large amount of leachate that requires a proper disposal. This study was carried out to analyze the effect of municipal solid waste leachate in soils, in this way, different tests of physical, chemical, mechanical and mineralogical properties were performed on two samples of a residual soil from the Batolito Antioqueño, located in Rionegro city. For the first sample, geotechnical characterization tests were executed in the natural soil condition. On the other hand, the same tests were implemented in the second sample after go through a leachate process. Were found important variations in the properties of the soil affected by the process of contamination when compared with the properties of the natural soil condition.

Keywords : Leachate; solid waste; tropical soils.
