Final Conference June 24 - 25 Maastricht, The Netherlands

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
3
Case approach followed
Additional interviews
- Water boards- Rijkwaterstaat Waterdienst- Ministry of VROM- WFD project office- CSN- RIWA Maas
Results evaluated in inquiry

Meuse River Basin Length: 905 km; h: 384 m From Pouilly-en-Bassigny (Fr)
through the Ardennes (Be) 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

Specific challenges
• International river basin: five countries/six regions(FR, LU, WL, FL, GE, NL)
• Fear to get “punished” by the EU when the ambition level is set too high

Lessons learned from case study (1)
Focus on diffuse emissions reduction
e.g. cadmium, PAH,
pesticides, fertilizers, pharmaceuticals,
...

Delay for achieving good chemical status expected until 2015, 2027, or later...
reconsider WFD demands / EQS adjust ambition level
(take more /other measures) effect of measures?

Lessons learned from case study (4)
Growing importance of emerging substances
look beyond WFD demands pay attention to extreme conditions
(floods, calamities)
