  1. REFCOND EU Water Framework Directive project funded by the European CommissionDG EnvironmentIncluded in the EU Water Directors “Common Strategy on the Implementation of the WFD”

  2. REFCOND • Lead country: • Sweden • Administration: Swedish EPA • Co-ordination: Swedish Univ. of Agr. Sciences • Associated partners: • Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, The Netherlands, Norway, Portugal, Spain and UK; JRC

  3. Objectives • To develop an operative definition of type specific reference conditions • To develop criteria for selecting techniques for establishing type specific reference conditions • To develop principles for setting the boundaries between high, good and moderate ecological status

  4. WFD requirements • Biological reference conditions should be identified for each type of body of water • The reference conditions must satisfy certain chemical and hydro-morphological criteria

  5. WFD requirements • Criteria for reference conditions: • Hydro-morphological and physico-chemical parameters should reflect totally, or nearly totally, undisturbed conditions • Specific synthetic pollutants should have concentrations close to zero or at any rate below the limit of detection • Specific non-synthetic pollutants should have concentrations within the range normally associated with background levels

  6. WFD requirements • Identification of reference conditions: • Spatial data - existing monitoring sites • Historical data • Paleolimnology • Models - hindcasting and/or predictive • Expert judgement

  7. Classification Deviation Status 1  High No/minimal  Good Slight Biological parameter value observed Reference biological value  EQR= Moderate Moderate Poor Bad 0

  8. Work programme Work packages: 1. Co-ordination 2. Establishment of project web-site 3. Agreement on common definitions 4. Review of techniques 5. Evaluation of techniques 6. Elaboration of first protocol draft 7. Review and validation of protocol 8. Finalisation of protocol

  9. Evaluation of techniques WORK PROGRAMME WORK PROGRAMME Evaluation of techniques and principles used by Member states for identification of reference conditions and principles for delineation of quality classes.

  10. First draft guidance • Elaboration of first draft of guidance. • Typology • Reference conditions • Principles for setting class boundaries

  11. Typology (1) • In the WFD implementation typology is required for different purposes: reference conditions, reporting, intercalibration • Reference conditions and reporting have different typology requirements

  12. Typology (2) • System A is not suitable for type-specific reference conditions • types are not ecologically meaningful • within-type variability is not tested, but is likely to be too large

  13. Typology (3) • Because in System B class boundaries are unspecified, there is a risk that different countries use incomparable systems • This would be an obstacle for comparison and harmonisation of assessment systems • A single, transparent core typology (to be refined locally) would be beneficial

  14. Typology (4) • Reference conditions: site-specific RC preferable, but this requires models based on data and/or expert knowledge • To achieve this, a European initiative to bring together the data would be required

  15. Availability of data for water body type Suggested Approach Yes Spatial network + predictive model No Minimally impacted sites available elsewhere? Borrow data and use in spatial network + predictive model Yes No Yes Predictive model eg.palaeoecology; hindcasting Historical data? No Yes No relevant sites or data? Expert judgement model concept and test when data become available Determining reference conditions Minimally impacted sites available?

  16. Setting Class Boundaries

  17. WFD - the normative classification can be summarized as: • high≈ no or only minor deviations; • good≈ low levels of disturbance, but deviate only slightly; • moderate≈ moderate deviations and significant effects; • poor≈ major biological alterations and substantial deviation; • bad≈ severe biological alterations and large deviation.

  18. Factors to be considered in setting class boundaries • number of classes - scientific or political • stressor - response relationship • variance within and among classes • errors

  19. high good moderate poor bad 1 0 EQR Quantifying ecological status: problem of errors

  20. Review and finalisation of guidance • Review and validation of protocol. • All Member States are expected to review and comment on the guidance document • Will be finalised autumn 2002
