  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DG ENV • Discussion of the comments received by CMA members • Agreement on the structure and principal content of the draft guidance document • Distribution of work amongst members of the drafting group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?

  12. Gaps in the Current Draft 4.4 Surveillance Monitoring 4.5 Operational Monitoring 4.6 Investigative Monitoring 6. TECHNIQUES FOR ANALYSIS 6.1 General – Quality Assurance 6.2 Water Analysis Annex A Glossary Annex B Substance Guidance Sheets Annex C Case Studies

  13. Group Parameters • Definition of indicator compounds if possible • Polybrominated diphenyl ethers • Nonylphenols • Octylphenols • Short-chain chlorinated paraffin's • HCH • Endosulphan • DDT • What congeners/isomers should be analysed for? • How to report results for substance groups or mixtures of isomers? • How to set performance criteria? • How to handle “less than” results for individual isomers/congeners?

  14. Substance Guidance Sheets • Idea behind it • Provide summary information for a certain substance/parameter on • Physico-chemical properties • Environmental quality standards • Available standard methods • Method performance characteristics • Other suitable methods • References • Specific comments and recommendation • Applicable to priority substances, other pollutants, and physico-chemical parameters • Adding information on available CRMs? • What about methods for analysis of biota and sediments? • 23 Substance guidance sheets have already been completed

  15. Annex – Case Reports • Experience reports regarding chemical monitoring from Member States on e.g. • Monitoring design • Selection of surveillance monitoring sites • Use of rotating monitoring networks • Time and design of investigative monitoring • …… • Sampling strategies • Use of screening methods • Confidence and precision • ……

  16. Time Schedule • Filling the existing gaps in the current document as far as possible • April 13 • Written comments on the draft guidance document • April 13 • Second revised draft • May 3, 2006 • Information to SCG • May 3, 2006 • Presentation of the second draft to the plenary • May 22, 2006, Rome
