Licencing of dredging activities is based on environmental analysis, including measuring levels of contamination. The contaminated dredged materials may upset the ecosystem balance at their disposal site. In these cases, officials take actions before the licence is granted. The types of contaminants
The Hunze en Aa’s water authority and Ecoshape recently built a 40-metre-long test dike in front of the sea dike on the Dollard. For the construction of the test dike the contractors used clay taken from the clay ripening plants that processed sediment from the seaport channel of Delfzijl and the Br
