The environment underground pollution from ETBE and MTBE has increased in recent years due to the augmentation of consumption of petroleum hydrocarbons. These are the main source of this kind of pollution.
After four years of research and development GEOAMBIENT has developed BACTEAU technique based on bioestimulation and bioaumentation for soil and groundwater polluted by additives of oil and its derivatives.
The research has identified bacteria that can degrade notably ETBE, MTBE and also petroleum hydrocarbons and BTEX.
When it is time to treat oil pollutants in the subsoil, a group of enriched bacteria is injected as a suspension through treatment piezometers.
