The European Eutrophication Activity and the UWWT and
Nitrate Directives
Ana Cristina Cardoso
Overview
WFD-CIS Eutrophication Activity
Eutrophication in EU policy− Requirements for assessment
and classification in UWWTD, ND and WFD
− Harmonisation of class boundaries
Introduction− Eutrophication is an issue in various water policies and
regional conventions− There remains considerable divergence in the specific
requirements for assessing eutrophication and different monitoring and reporting requirements
− These lead to a Eutrophication Activity that take a wide view to harmonise across all policy areas but firmly based on the WFD
− Contemplating all water categories− Discussions on content started mid-2003 involving all
relevant working groups (ECOSTAT, EMMA, ND and UWWD Committees)
− In 2004 the Eutrophication activity was initiated under the CIS of the WFD

1. Introduction2. Overall conceptual framework for the assessment of
eutrophication3. Overview and common understanding of eutrophication in EC
and international policies4. The WFD concept of ecological status in the context of
eutrophication (Ecostat)5. Overview of current eutrophication risk assessment
methodologies and criteria in European countries6. Towards harmonisation of classification criteria7. Monitoring- Guidance on integration of requirements
stemming from various obligations 8. Case Studies9. Next steps
Contents - Eutrophication Guidance
Annexes - Eutrophication Guidance
• Annex 1: The understanding of eutrophication
• Annex 2: Indicative check-lists for category specific features of the impact of eutrophication
• Annex 3: Summary tables of information collated under this activity on existing eutrophication related assessment methodologies and criteria used for lakes, rivers and marine waters
−After an extensive consultation, an interim version of the guidance document has been presented to the Water Directors in London, November 2005
−The Water Directors have decided for the publication of this interim version (No11) of the guidance with the following title: "Towards a Guidance Document on Eutrophication assessment in the context of European water policies. Interim document"
Eutrophication Guidance Current Status
• WFD (2000/60/EC)
• Urban Waste Water Treatment Directive (91/271/EEC)
• Nitrates Directive (91/676/EEC)
• Habitats Directive (92/42/EEC)• Shellfish Waters Directive (79/923/EEC)• Freshwater Fish Directive (78/659/EEC)• Bathing Water Directive (76/160/EEC)• Abstraction of Drinking Water Directive (75/440/EEC)• National Emission Ceilings Directive (2001/81/EC)
Eutrophication in European policies
Directive/ Policy Assessment requirements Monitoring requirements
WFD Part of assessing Ecological Status Pressure from nutrientsProtected Areas
Phytoplankton, aquatic flora, macroinvertebrates, fishHydromorphological QEs Physicochemical QE
UWWT Directive
To identify Sensitive Areas
(…eutrophic or may become eutrophic in the near future)
Review Sensitive Areas at least every 4 years
Nitrates Directive
To identify polluted waters and designate catchments as Nitrate Vulnerable Zones
Review the eutrophic state of surface water at least every 4 years
Requirements to assess eutrophication

UWWT Directive Nitrate Directive
High Nearly undisturbed conditions
Non Eutrophic, designation of sensitive area is not required
Non Eutrophic, not a Polluted Water, designation of NVZ is not required
Good Slight change in composition, biomass
Non Eutrophic, designation of sensitive area is not required
Non Eutrophic, not a Polluted Water, designation of NVZ is not required
Moderate Moderate change in composition, biomass
May become eutrophic in the near future, designation of sensitive area is required
May become eutrophic in the near future, polluted water, designation of NVZ is required
Poor Major change in biological communities.
Eutrophic, designation of sensitive area is required
Polluted water, designation of NVZ is required
Bad Severe change in biological communities.
Eutrophic, designation of sensitive area is required

Avoid deterioration in status in accordance

Future developments–The Steering Group has prepared a proposal to continue the activity in 2007-2008 which was presented to the Water Directors meeting in Finland (30 November - 1 December 2006)
– Update will consider the outcome of the WFD intercalibration and results of second application of the OSPAR common procedure
