Soil- or groundwater contamination’s above specified limits are necessary to be decontaminated. A decontamination can be realized through a variety of options, such as:
- Discharging of the soil from the original location;
- 'Pump and treat';
- Air extraction;
- Nutrient injection;
- IBC criteria (Isolate-Manage-Control);
- Monitoring (biological decontamination).
These decontamination options need decontamination plans. Depending on the choice of decontamination operation a leveling plan need to be produced.
Execution of the decontamination is supervised by a environmental inspector. The environmental inspector is functioning as an intermediair and keeps records of discharged soil- and groundwater quantities.
Afterwards a evaluation report is produced.
