D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 2 International Office for Water Non profit making association (NGO with 150 members), State approved Created in 1991 (20 years!) Missions : international networking: INBO services in the water domain (Training centre, Information and data Centre) European and international cooperation: twinning, CIS-SPI, 6 th WWF Marseille 2012 http://www.oieau.org/

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 4 WFD priority substances: the project assistance to DGENV on WFD priority substances One main activity: monitoring based prioritisation Prioritisation methodology (INERIS) + data collection (IOW) EU relevant, scientifically based and pragmatic From universe of substances to a manageable list (30-50 substances) Minimum data requirements Target: pollution of surface water compartments (Water, sediment and biota) (Adapted from V.Bonnomet, INERIS)

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 5 WFD PS: the data collection steps 1.Define the needs: minimum mandatory and optional fields, voluntary basis 2. Create the End user tool (MS Access) for data collection 3. Data collection + helpdesk 4. Gather data, analyse, define the corrections and quality checks, test and implement 5. Import data in a central database 6. Treat data for prioritisation
6
D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 6 Tools to support the collection The Microsoft Access End user tool (+template) The How to use guide A Web page www.oieau.fr/WISE-end-user-tool and a helpdesk
7
D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 7 WFD PS: Data collection 2008 and 2009 A strictly defined template with 22 mandatory fields Flexibility introduced on 8 fields (longitude/latitude, LoD/LoQ, type of station, date of sampling, biota species, laboratory name) A flexible data collection tool, and detailed documentation for non experts, to: minimise reporting burden: except on some validity checks, any fraction, any unit, any substance even with missing mandatory fields is accepted allow decentralised distribution of the tool (experienced by RO) maximise quantity of data collected Interaction between data provider and consultant for Quality checking before selection of relevant dataset(s) correction of missing fields and coherence

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 8 WFD PS: Preliminary data treatment Only datasets for surface water River, Lake, Transitional, Coastal, Marine Elimination of : data measured before year 2000 non relevant parameters (e.g. P(tot), Nitrates, etc.) datasets for which neither LOD nor LOQ were provided Insufficient precision of matrix or fraction (all ”other”) Correction station location if missing substance name (in national language) or CAS code if detected wrong unit (in national language) fraction when it can be gathered with existing fractions date of sampling or date of analysis format or when one is missing Harmonisation of the measurement units ( 130 units on the 1130 substances provided and 102 units on 21 Tin compounds ) Water: µg/l, Sediment: µg/kg dw, Biota: µg/kg ww

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 9 WFD PS: Central Database creation A central database similar to the End User tool (Station, Sampling, Analysis) structured database (PostGre/PostGIS, SQL Language) on-line management tools for import of datasets (SQL based interface) Maintenance tools for storing and saving (SQL calculation modules) All individual files imported (more than 50 files, up to 40 GBytes) export XML file End User Tool : one for each data provider Use for prioritisation Internal checks and validation import Central database Discarded (cat. 1 incomplete)

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 13 WFD PS: The data quality aspects -Example: performance criteria set in Directive 2009/90/EC: LoQ < 0,3 x EQS
14
D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 14 WFD PS: Conclusion The first data collection of regular chemical monitoring data under WFD and a huge database A collaborative exercise involving EU and MS authorities A complete report on quality assessments (restricted, accessible to CIS expert) concluded future data collection will require: Adaptation of the data collection template and tool additional collection rules (more mandatory fields, checks…) A checking mechanism on the data content (station location, …) more quality information (LoD and LoQ, accreditation…) Use of WISE and INSPIRE reference lists Possible development could include: Use of a shared EU wide structured water language (Reportnet) Use of shared reference lists (Reportnet Data Dictionary, ROD…) Use of shared scenarios for example the French system: SANDRE and EDILABO

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 15 SANDRE, French data and metadata for water A cornerstone of French water information system Water Agencies RBD authorities IndustriesMunicipalitiesLaboratories Ministry of Environment I do not understand the data sent I can not read the format I need to develop a specific mapping for each data collection He used codes I do not know SANDRE Data interchange in an evolving context: WFD implementation, progress of scientific knowledge… Numerous actors with different needs and tools

D. Preux, B. Fribourg-Blanc, Norman data exchange Workshop, 20-21/04/2011 slide 22 Main conclusions Based on WFD PS first experience: the first voluntary exercise proved feasibility of collecting big datasets Tool known: can be used for future Quality of data expected to improve: QA/QC Directive entered into force Aug. 09 and transposed Aug. 11 (art 4 minimum performance, Art 5 calculation of mean, Art 6 ISO 17025) EQS Directive a need to improve robustness and reliability of data collections More mandatory fields a need for more automatic data interchanges French SANDRE proves the feasibility of automating the process A collaborative work: crucial for the success !!!
