| Heating oil was spilt during the filling of an oil tank.More than 1000 litres heating oil was spillt. This led to a heavy contamination of the groundwater. Remediation was undertaken using mobile oil treatment equipment and by skimming. |
| Project description |
Further spread of contamination was prevented with the help of groundwater depression technology. The clean groundwater from the subsurface depression pump was reinfiltrated through the peripheral infiltration wells.
Benefits:
Additional soil washing effect
Significant reduction in the time to complete remediation
Date of operation: 1990-1993
Groundwater table: 18 m below ground level
| Groundwater well with oil skimming equipment |
Free floating product was removed from the surface of the groundwater in the central remediation well by means of oil skimmers and mobile oil separators / oil storage tank.
