1 Vienna, 22.06.2005 | Slide 1 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Quality of Groundwater in Europe Vienna, 22 June 2005 Andreas Scheidleder Umweltbundesamt, Austria Member of the European Topic Centre on Water (ETC/WTR)

2 Vienna, 22.06.2005 | Slide 2 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Content EEA mission Groundwater quality in Europe Indicator development, underlying data Dataflow (EIONET, Reportnet) Outlook - Integration into WISE

3 Vienna, 22.06.2005 | Slide 3 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER EEA EEA mission The European Environment Agency is the EU body dedicated to providing sound, independent information on the environment.... timely, targeted, relevant and reliable information to policy-makers and the public. http://www.eea.eu.int

4 Vienna, 22.06.2005 | Slide 4 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER EEA indicators 37 policy-relevant core indicators = stable and manageable basis for indicator reporting by EEA Used for: … State of environment reports every five years, indicator reports focusing upon specific issues Indicators were discussed by members, approved by EEA management board

5 Vienna, 22.06.2005 | Slide 5 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Indicator profile Policy question Policy context and targets Graphical presentation Assessment Methodology of – assessment – data collection and treatment Uncertainty of – Methodology – Data

6 Vienna, 22.06.2005 | Slide 6 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Quality of Groundwater in Europe (part of CSI 020 - Nutrients in freshwater) Key policy question Are nutrients decreasing in our freshwaters? Specific policy question Is nitrate concentration in groundwater decreasing?

7 Vienna, 22.06.2005 | Slide 7 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Key message There is no evidence of a decrease (or increase) of nitrate concentrations in Europe's groundwaters + Detailed assessment … + Description of methodology Quality of Groundwater in Europe (part of CSI 020 - Nutrients in freshwater)

8 Vienna, 22.06.2005 | Slide 8 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Nitrate in GW in different EU regions Methodology Arithmetic means of: Stations GW-body EU region Consistent time series (no data gaps)

9 Vienna, 22.06.2005 | Slide 9 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER PROBLEM: Consistent time series

10 Vienna, 22.06.2005 | Slide 10 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Nitrate trends in countries Methodology LOESS smoother min 8 years, max 15 years Consistent time series (with max 1 data gap)

11 Vienna, 22.06.2005 | Slide 11 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Nitrate status in countries Methodology Latest year available Concentrations classes at station level

12 Vienna, 22.06.2005 | Slide 12 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Underlying Groundwater Data What is covered? All important groundwater bodies Criteria for important At least 300 km² OR of regional, socio-economic or environmental importance in terms of quantity and quality OR exposed to severe or major impacts

13 Vienna, 22.06.2005 | Slide 13 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Information and Data collected GW-bodies - Location (GIS-data) GW-bodies - General characterisation – … (hydro-)geology, pressures, etc. Sampling sites - Location (co-ordinates) and type Quality data – raw data on: – Nitrate, Ammonium, Dissolved oxygen – Hazardous substances (e.g. pesticides) – Time series as long as possible Saltwater intrusion - Location + supportive information

14 Vienna, 22.06.2005 | Slide 14 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Data collection Based on already available data (derived from the policy questions) Annual data collection … performed via the EIONET … supported by Reportnet EIONET's integrated data reporting system Internet based tools Transparent and tracable data reporting

15 Vienna, 22.06.2005 | Slide 15 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER EIONET EEA NRC NRC NFP ETC ~ 300 national institutions 1 Agency 5 Topic Centres 31 + 6 NFPs … is a collaborative network of the EEA

16 Vienna, 22.06.2005 | Slide 16 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER 31 6

17 Vienna, 22.06.2005 | Slide 17 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Reportnet Data Preparation What to do ? How to prepare ? How to deliver ? Central data repository Data Delivery

18 Vienna, 22.06.2005 | Slide 18 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Key element - Data Dictionary Precise definition of requested data – Data structure and data elements – Definitions and methodologies (tables, elements) – Format, data type, plausibility limits of elements Clear preparation & provision guidance Basis of Data exchange modules (xls, WebForm) Data is quality checked against Data Dictionary

19 Vienna, 22.06.2005 | Slide 19 EUROPEAN ENVIRONMENT AGENCY EUROPEAN TOPIC CENTRE ON WATER Outlook – Integration into WISE All future water data collection should fit into one common data stream in a shared information system (WISE). Shared pool of SOE information for all organisations preparing EU level assessments Make best use of EIONET developments
