  1. EEA/ETC Water – EIONET Annual Workshop Helga Lindinger Andreas Scheidleder

  2. Progress on EWN – groundwater network Update 2003

  3. Progress on EWN – groundwater network overview 1/10

  4. Progress on EWN – groundwater network Quality data 2/10 • NO3, NO2, NH4, O2 provided by most of the countries (20) if missing  O2, NO2 • Pesticides, Hazardous substances provided by a few countries (10) broad variety concerning substances and time period

  5. Progress on EWN – groundwater network GIS Information 3/10

  6. Progress on EWN – groundwater network GIS Information 4/10 • map is compilation of last years‘ GIS deliveries (13 countries) • still open questions concerning GIS relevant information (e.g. for projection) • maps as .jpg files • asked to provide GIS information in ETRS 89

  7. Progress on EWN – groundwater network data flow general 5/10 Feedback • Less requests from NRCs • Less changes of NRCs • Less contribution via e-mail, mostly via CDR • Some requests on format checking in advance • Data formats closer to the requested formats • Still homemade formats • Additional unexpected data formats (Access database: ~500.000 datasets for self search)

  8. Progress on EWN – groundwater network Formal criteria 6/10 Formal (templates) • Original templates not used (homemade etc.) • Old templates used • Original templates modified(field names, raws and columns deleted or moved, …) • Resending of old data, overwriting of validated • Data linked to the wrong year • ! New templates  automatically generated DD

  9. Progress on EWN – groundwater network Formal criteria 7/10 Formal / Values • Datasets do not fit the interface description • Parameter names in local language • Data files not named correctly • Commas instead of dots • missing links between bodies and measurement points • units different to the template (mg/l - µg/l) without notice • co-ordinate system not specified

  10. Progress on EWN – groundwater network Formal criteria 8/10 Strangedeterminands

  11. Progress on EWN – groundwater network lack of data 9/10 • core set of determinands (number of countries) latest year available • NO3 (26), NO2 (22), NH4 (24), O2 (17) • atrazine (12), lindane (7), simazine (9) • consistent time series (1993-2002) e.g. NO3 – 12 countries, 90 bodies out of >400 • hazardous substances broad variety (determinands, time coverage)

  12. Progress on EWN – groundwater network lack of data 10/10 • saltwater intrusion (5) even statement missing • GIS information (13) data should be provided in ETRS 89 groundwater body Code is key link between quality data and map
