| The Dutch process involves first making a preliminary investigation of an area which should be able to pull in temporal as well as spatial contamination information, this is defined the Dutch standard NEN5717. | The Dutch process involves first making a preliminary investigation of an area which should be able to pull in temporal as well as spatial contamination information, this is defined the Dutch standard NEN5717. |

| As stated in §5.3.3 of the NEN 5720, the research strategy may be adjusted by changing the compartmentalization, the number of sediment cores, the thickness of the sampled layer or the number of analyses. Although the number of sediment cores may be limited, enough cores have to be taken in order to get a clear insight into the spatial distribution of the sediment contamination. Sampling of the top sediment layer suffices. This is the sediment layer that interacts with the water column. The thickness of this interactive layer depends on factors such as water type and water dynamics (flow rate, number of passing ships etc.). It is advisable to include a layer of 20-50 cm thickness in the survey." | As stated in §5.3.3 of the NEN 5720, the research strategy may be adjusted by changing the compartmentalization, the number of sediment cores, the thickness of the sampled layer or the number of analyses.
