Chemical Monitoring Activity Draft Guidance Document on Surface Water Monitoring

1. Chemical Monitoring ActivityDraft Guidance Document on Surface Water Monitoring

2. Original Time Schedule • Comments in the draft outline • December 15 • Nomination of technical experts • December 15 • Exchange of already existing national monitoring strategies and respective guidance documents • December 31 • First expert meeting to distribute work amongst experts and exchange of experiences and views • January, venue and date to be decided • First draft • March 15

3. Drafting Group • Chair: UBA / JRC-IES • Nominations for the drafting group from: • Austria, Belgium, Denmark, France, Germany, Ireland, Italy, Norway, The Netherlands, Sweden, Spain, UK • 1st Drafting group meeting • JRC-IES in Ispra, January 23/24 • Participants from Austria, Denmark, France, Germany, Ireland, Italy, Norway, The Netherlands, Sweden, Spain, UK and DG ENV • Discussion of the comments received by CMA members • Agreement on the structure and principal content of the draft guidance document • Distribution of work amongst members of the drafting group

4. Main Comments on the Draft Outline • General Agreement • Principal issues of discussion: • Structure and content of chapter 3 (monitoring design) • Terms and definitions: • Chemical monitoring, significant, …. • Aspects to clarify: • Matrix selection and related subjects • Monitoring design (monitoring points, frequency) • General physico-chemical parameters for SPM, sediment and biota • Sampling representativeness • Monitoring designed for specific purposes (e.g. trend)

5. Structure of the Document • 1. PURPOSE AND SCOPE • 2. BACKGROUND • 3. TERMS AND DEFINITIONS • 4. MONITORING DESIGN RELATED TO • SURVEILLANCE MONITORING • OPERATIONAL MONITORING • INVESTIGATIVE MONITORING • 5. TECHNIQUES FOR SAMPLING • 6. TECHNIQUES FOR ANALYSIS • 7. ALTERNATIVE MONITORING METHODS • 8. REFERENCES • 9. ANNEXES • SUBSTANCE GUIDANCE SHEETS • CASE STUDIES New version!

6. Common Understanding (1) • Current guidance is supplementary to CIS monitoring guidance • Reference to the CIS Guidance where appropriate • Additional guidance where necessary • Solely focus on chemical monitoring • Chemical monitoring refers to • Priority Substances • Annex VIII Compounds • Physico-chemical parameters • Co-factors required for interpretation of results • Compliance issues and statistical treatment of data should be dealt with in the common issues group • No guidance on deriving background reference concentrations for heavy metals, for the time being

7. Common understanding (2) • Non-legally binding guidance document • unequivocal interpretation of WFD chemical monitoring obligations • the production of coherent and comprehensive monitoring data with demonstrated and comparable quality throughout Europe • Harmonisation of WFD monitoring strategies and practices throughout Europe • A balanced document that does not compromise existing good practice operated in member states • Flexibility for adaptations to local conditions • Principal matrix for assessing compliance with EQS • Whole water • Compliance with non-deterioration principle • Whole water, biota or sediment

8. Identified Problems/Questions • EQS Directive has not yet been published • Environmental quality standards? • Added risk approach? • Definition of indicator compounds? • Compliance issues not yet clarified • How to deal with “less than values”? • Guidance on how to determine method performance criteria (uncertainty, LOD/LOQ)? • Criteria to reduce monitoring frequencies?

9. Identified Problems/Questions • How to assess results in case method performance criteria cannot be met? • How to use results from sediment and biota monitoring to assess compliance? • How to use expert judgement for assessment of compliance with EQS • Passing sampling techniques provide time-weighted average concentrations • Only dissolved water concentrations • Fit for assessment of compliance with EQS? • Uncertainty? • What compounds?
