The present invention relates to a consortium of microorganisms useful for the bioremediation of bodies of water contaminated with 1,2-dichloroethane (1,2-DCA). In particular, the present invention relates to a consortium of microorganisms able to degrade 1,2-DCA to ethylene, substantially without producing toxic halogenated intermediates, said consortium, when present in an aqueous liquid, preferably under anaerobic conditions, being tolerant to a concentration of 1,2-DCA in solution in said aqueous liquid greater than or equal to 1000 mg/L, preferably comprised between 1000 mg/L and 4000 mg/L, and more preferably comprised between 2000 mg/L and 4000 mg/L. In a second aspect, the present invention relates to a method for the bioremediation of a body of water contaminated by 1,2-DCA, where in said body of water the concentration of 1,2-DCA may be greater than or equal to 1000 mg/L, preferably comprised between 1000 mg/L and 4000 mg/L and more preferably comprised between 2000 mg/L and 4000 mg/L, which comprises placing in contact with said body of water, preferably under anaerobic conditions, the aforementioned consortium of microorganisms able to degrade the 1,2- DCA.

The present invention concerns a decontamination process. More specifically, the present invention concerns a process for treating a soil contaminated by organic non-hydrocarbon water insoluble pollutants, comprising the concentration of said pollutants in a fraction of "fine particles" of soil and the separation of the latter from the other fractions of soil. The aforementioned fraction of "fine particles" of the soil in which the organic non-hydrocarbon water insoluble pollutants are concentrated, which is lower than the quantity of soil treated, may be decontaminated through further appropriate treatments or sent for safe disposal. The process according to the present invention also differs due to the fact that no liquid contaminants are produced to be subjected to decontamination treatment prior to recycling or release into the environment.
