The implementation of the EC Water Framework Directive

in Norway

Activity By Update

Division into River Basin districts; Designate responsible authority

Characterisation of water bodies and assessment of human impact

2004

Development of biologically based classification system (to establish ecological status)

2006

Intercalibration of systems for separating between good and moderate status

2006

2012?

Main time table -> 2006

Norwegian progress

• Designate responsible national authority – Ministry of Environment, 2004

• Division into river basin districts and regional river basin authorities, autumn 2005

• Characterise the water bodies of each river basin, good progress

• Find reference conditions,currently being done

• Surveillance programmes• Develop plans to achieve the good status

Characterisation of water bodies in Norway

Ecological status is divided into

By 2015, all water bodies should have a ”good” status.

These will be water bodies AT RISK of not achieving a good status.

Norway has also made a group ”Possibly at risk”

Criteria for risk assessment

• Measurement data whenever they exist

• Otherwise pressure is used: – Extent of agricultural land– Urban areas– Industry, Mining activities– Sewage treatment plants and settlements not

covered by STP– Introduction of new species and loss of others

Development of a GIS-tool

Characterised water bodies in River Glomma, Norway’s largest river

Large areas are not at risk

Pressures increase in the south of Glomma

Next step – regional quality assessment

• Since regional river body authorities have not yet been designated, all 18 counties have been given this task

• The GIS-tool has been distributed to all counties for QA and input of additional regional/local information

• NIVA is assisting the counties in Eastern Norway

WFD – spin-off effects

• Increased co-operation between Directorates dealing with water

• Increased co-operation between science/monitoring institutes (water quality – quantity)

• Increased co-operation between regional management?
