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 , 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: ~ 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
Strange determinands

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 ( )
e.g. NO3 – 12 countries, 90 bodies out of >400
hazardous substances
broad variety (determinands, time coverage)
core set of determinands: only latest year

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
