Some Proven Benefits of Polymer Use in the Treatment of Sediments in Recent Dredging Projects

To show the success of polymer use in highly contaminated areas, two recent projects are presented: at Port-La-Forêt harbour in La Forêt-Fouesnant, France and at the Kishon River seven kilometres downstream from Haifa, Israel.

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.
