Environmental Dredging of a Chromium Contaminated Fjord
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.
Environmental Guidelines for Aquatic, nearshore and upland Confined Disposal Facilities for Contaminated Dredged Material
Information and recommendations regarding Confined Disposal Facilities, including the management of contaminated dredged materials.
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.
Framework for Research Leading to Improved Assessment of Dredge Generated Plumes
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.
Mechanical Treatment of Dredged Material. The Malcontenta Plant in the Lagoon of Venice
In an extensive pilot study, contaminated sediment dredged from an industrial channel in Venice has been mechanically treated by dehydration at a purpose-built plant near the harbour.
Realisation of the Ketelmeer Storage Depot
A well-planned storage depot will change the entire scenery of the highly polluted Lake Ketelmeer, simultaneously cleaning up contamination and creating recreational islands and non-cultivated nature reserves.
Emissions of Porewater Compounds and Gases from the Subaquatic Sediment Disposal Site “Rodewischhafe”
The 1997 IADC Award was given to this paper which was presented at the International Conference on Contaminated Sediment in Rotterdam, in September.
The Sweep Dredge: High Accuracy Dredging Trials Continue
More techniques for dredging thin layers in contaminated waters have been tested on the Ketelmeer in 1996. A summary.
