MODE OF OPERATION

The facility is divided in three sections, each having its own access points so that they may be used individually. The platforms inside the building allow for the treatment of a significant amount of contaminated soils.

All soils delivered to the facility have been previously characterized so that the contaminant concentration be known. Samples are randomly extracted and verified to certify the concentration. Soils contaminated with petroleum hydrocarbons are piled in a specific location based on the type and concentration of the main contaminants.

The treatment used by Décontam does not generate contaminated water as the process does not require a significant amount of water and no sludges are accepted at the facility. Furthermore, the process being indoors, the soil is protected from the rain.

After treatment, the soils are disposed of in accordance to the table for the management of contaminated excavated soils ("Grille de gestion des sols contaminés excavés") published by the ministère du Développement durable, de l’Environnement et des Parcs, found in Annex 1 of the guidelines for the treatment of soils by biodegradation, bioventilation and volatilization.
