  2. Introduction case study: Dutch Meuse • Internal discussions • System approach required for decision support • How to deal with historic pollution and other types of diffuse pollution • Visits to water boards and RWS • Point sources largely eliminated • Lack of focus on chemical status • Measures should be taken on national or EU policy level Final Conference June 24 - 25 Maastricht, The Netherlands
