Synopsis

Regular removal of sediments is a necessity for proper water quantity management in the Netherlands. Sediment contamination causes problems for this. Where can the contaminated sediments be deposited? The New Dutch soil policy aims at the sustainable use of soils, and allows for area-specific regulatory approaches. The current approach, based on sediment classes, does not provide sufficient insight in risks of sediment deposition on land for terrestrial organisms, and does fir the new policy. In a research project of RIVM, RIZA and Alterra, focus was on the site-specific, integrated risk assessment of sediment deposition on land. A systems-approach was designed, so as to model where compounds come from, where they go, and which risks could exist as a consequence. The results of the project are reported in three consecutive reports. In this report, the systems approach is described, in a basic scientific-technical way. In the subsequent report, the integrated risk assessments are described similarly. The overview-report presents the prototype of a decision-support model for sediment deposition on land as developed from the systems-approach, including examples of its application. The prototype of the decision-support model has not yet been finished, as various regulatory decisions are awaited.
