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

to the North Sea (NL)
 Catchment area: 35,000 km2
 Population: 8.8 million
 Rain river; large differences
between summer and winter
discharge (< 10 – 3,000 m3/s)
 Source of water for drinking
water production, agriculture,
industry
 Important for navigation
