Bioremediation is a tool that can be effectively used in certain contaminated environments. Its main advantages reside in its low aggressiveness with the environment when applied “in situ”, and in the capacity to destroy contaminants.As a result of our research we are able to present the novelty of using our methods, as the way to avoid more expensive actions such as thermal desorption, or much terrible and ineffective, such as identifying the waste as dangerous, and its subsequent storage and custody without reaching to a definitive solution.This article presents the results we reached to and how we proceeded in the treatment of soils contaminated with hydrocarbons on land located in the engineering work of the high-speed train between Córdoba and Málaga. Thanks to the way of proceeding we obtained, within six months, decreases below 1500 ppm of TPH.We would also like to make available to the scientific community the success of using different mixtures, as well as the techniques and properties must be performed and measured.Coexistence of biosulphants, phosphants and the novelty of treating them with magnesium hydroxide, the results of the interactions between microrganisms and the pollutant and what conditions are needed of aeration and stimulation by mixture, shows the degradation capacity of the hydrocarbon and its sostenibility.Keywords: bioremediation, descontamination, hydrocarbon degradation , micro-organisms
