Description of the job
Remediation of polluted soils by Bioremediation technique
The characterisation plan realised in the warehouse's solvent area of the Aerosekur plant identified the presence of pollutants, mainly hydrocarbons. (see Characterisation plan sheet).
The effective remediation method used was a bioventilation process system, which optimises the local biological activity by injecting air, water, nutrients and oxygen into the subsoil.
According to the treatability tests performed in a laboratory on samples taken from the worksite, the contamination reduction programme aiming at bringing the levels below the limits set by the applicable regulation was respected as follows:
- 20% after 30 days
- 45% after 60 days
- 72% after 120 days
- 92% after 150 days
- below the limits after 180 days
