Environmental Dredging of a Chromium Contaminated Fjord
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.

A newly developed environmental feedback monitoring system allows a much quicker evaluation of impacts, which in turn enables dredgers to respond more quickly.

To build the 16 km long bridge-tunnel link from Denmark to Sweden requires the dredging of extremely hard layers of limestone, often in extreme weather conditions, with strictly controlled spillage limitations.
