On June 19/20, 2007 a visit was paid to a suspended particulate matter (SPM) sampling and monitoring site in the Ourthe river (Liège region), between the confluence with the Vesdre river and the mouth of the Ourthe in the Meuse river. The next day, a workshop was organised in which backgrounds, methods and procedures for SPM sampling and monitoring were discussed. Results of measuring SPM quantity and quality in the Meuse river basin were presented. The discussions were focused on the implementation of this matrix in WFD instigated monitoring programs. The workshop was very successful, with animated discussions.
