Abstract [en]

In a small lake in the subarctic region of Sweden an area of 250 m 2 was dredged using a novel dredging technique: Freeze Dredging. Freeze Dredging is performed by freezing the sediment and lift it while frozen. During the operation approximately 28 tons of contaminated material was removed. The environmental monitoring showed no harmful redistribution of sediment. Levels of petroleum contamination in the dredged area was reduced by 90%. Overconsolidation caused by the freeze/thaw cycle reduced the water content when the material thawed. Freeze Dedging can be used for removal of contaminated sediments. The technique is especially aimed for sediments with low water content and sediments with debris, boulders and rocks.
