The sediments in Valdemarsviken fjord in Sweden were contaminated with chromium from the discharge of untreated wastewater from tannery operations decades ago. The contaminated sediments were dredged, dewatered, solidified and placed as a engineered fill in a nearshore area.

Dredging and Valorisation: Treatment of Contaminated Dredged Material in the Port of Dunkirk, France
To meet recent legislative requirements in France, the Port Authority of Dunkirk has pioneered a new method for dewatering contaminated dredged material and readying it for further use.
There are two types of driving force that urge us to assess the effects of dredge-generated plumes, a genuine concern for the environment and the regulations that forbid us to dredge unless we can demonstrate that harm will not be caused to the environment.
