This work results from a laboratory simulation study of the ventilation decontamination process of diverse soils, which were reconstituted in reactors designed and constructed at specific purpose, after they had been doped with BTEX. The soil specimens were reconstituted with different characteristics, two spe ci - mens for each kind of soil. By using that laboratory simulation, the interactions among BTEX (Benzene, To - lue ne, Ethylbenzene and Xilenes) contaminants in gas phase and soil aqueous and solid phases were studied for the diverse soils. The soil conditions that might allow higher or smaller reversibility of intervenient pro - ces ses were also evaluated. The results obtained concluding that the influence of soil nature and their geo - technical conditions are not so clear, how was foreseen, being obvious the importance of water content, that was maintained constant during all tests, by saturation of percolant air flux.
