Bioremediation uses degradation capacity of indigenous or inoculated microorganisms to biodegrade organic constituents adsorbed to soils. It is a technology that generally requires long periods of treatment to reach the desired clean-up goals. The objectives of the reported work were to evaluate the capability of bioremediation to achieve legal clean-up goals in a humic soil with an organic matter content of 14% and contaminated with benzene. The benzene quantification was performed by gas chromatography. The results of the experiments were used to calculate process efficiency and remediation time. It was concluded that: a) the bioremediation is an effective process; b) bioremediation efficiencies were near 100%; and c) the remediation times were 92, 139 and 354 hours for soils contaminated with benzene levels of 70, 90 and 120mg*kg-1, respectively.
