Field resesearch dissemination of sediment

Sediment that is released during the maintenance of watercourses may contain small quantities of pollutants. Because the sediment is disseminated on farmland, the question arises whether this affects the quality of the soil.

Abstract

In the maintenance of waterways lots of dredging comes up, that usually will be distributed on adjacent parcels. The dredging can and may contain small quantities of pollutants. This raised the question whether the spread of slightly contaminated dredged material is environmentally sound. The purpose of this study is to examine on a practical scale or distribution now and in the future results in a degraded soil quality.

The project started 2008. In 2011, the research data were interpreted and presented in a final report. Until now the spread of slightly contaminated dredged material on adjacent parcels has not led to a deterioration of soil quality in clay and peat lands. In order to prevent distribution of dredged material with a higher impurity concentration, additional criteria are required with regard to the quality of the dredged material to be spread.
