This work deals with the problem of gasoline indicator compounds (BTEX – Benzene, Toluene, Ethylbenzene and Xylenes) behavior in different types of soils, in the unsaturated zone. Laboratory simula - tions were used to create the contamination conditions and to study the interaction processes developed among existing phases in three different soils with BTEX, in controlled geotechnical and chemical condition systems. The simulation aimed at understanding which aspects of the interaction between the phases of the soil are the most important ones. The laboratory simulations for contamination were developed to understand and to pre - dict the contaminant retention process on solid phase. The results obtained concluding that water content (> 4%) plays a role that minimizes the influence of the soil mineralogy. Soils mineralogy is especially impor tant in dry to very dry soil conditions, helped by the concentration of the contaminants.
