Research priority water soils obv multi-criteria analysis
Description
‘The research priority water soils is an integrated measure of pollution, ecological value, the chance of sustainable restoration and the social importance of Waterloop segments, developed in a spatially explicit way. The research priority is based on the known status of the watercourses. The result is an interactive map layer of research priorities in which a ranking of Flemish Waterloop segments has been created through a multi-criteria analysis (MCA) that draws up the research list. The higher the research priority of a watercourse segment, the higher that segment is on the research list. The red Watercourse segments on the map have the highest research priority. The criteria underlying the research priority for a watercourse are the triad quality assessment, the physico-chemical signal values, the multimetric macroinvertebrate index, the structure, the fish index, the strahler order, the adjacent use of space and location in surface water extraction area. Attention: The results included in the water floor explorer are a snapshot. In a number of cases, the water bottom may have been sampled to carry out the clearance work. In this case, the results are no longer representative of the current status of the waterbed. After all, the sampled sediments have been cleared from the watercourse. The research priority water soils supports the identification of water soils to be examined as a matter of priority. Testing against trigger values, soil remediation standards and Vlarebo Annex V & VI give an initial insight into which pollutants may be problematic parameters for the clearance and processing of the water soils. Statements are only based on historical and recent water bottom quality data available per segment. Only analysed pollutants are taken into account. Not all measurement results are available digitally and can be consulted in the Waterfloor Explorer. This is particularly true for pollutants which were not frequently analysed at the time of sampling. For these “new emerging substances/emerging contaminants”, it is important to consult the data contained in the reports themselves. The absence of certain measurement results in the Waterfloor Explorer should therefore not lead to the conclusion that no contamination is present. Additional water soil testing is always necessary to provide a correct picture of the current water soil quality per watercourse segment.’
