Drafting Group on Reporting on State of the Environment and Trends Current Status of Eionet-Water
Background and scopeReporting process and information visualisationCurrent status of Eionet-Water data flowsConcluding comments
Eionet-Water (formerly Eurowaternet) • Designed to give a representative assessment of water types and variations in anthropogenic pressures within a country and also across the EEA area • Does not necessarily give a representative view of individual catchments or of River Basin Districts. • Based on national monitoring networks • Changes in station selection may be required as national monitoring becomes WFD compliant
Eionet-Water • EEA Priority Data flow for: • rivers, • lakes, • groundwater, • transitional, • coastal and marine waters • Water quantity • Updated annually • Moral rather than mandatory reporting obligation
Requested determinands • Nutrients, organic pollution indicators and hazardous substances in rivers and lakes; • Nitrate, ammonium, dissolved oxygen and pesticides in groundwater; • Nutrients, chlorophyll and hazardous substances in transitional, coastal and marine waters (TCM); • Hazardous substances in biota and sediments in TCM; • Water quantity in terms of precipitation, river flows and renewable water resources.
New (non-Priority) data flows are being developed • Need more and different data to improve assessments • Emissions to water • Working closely with Pilot River Basins, WFD Article 5 reports, • Data from national sources, river and marine conventions • Biological and hydromorphological quality elements
Quality elements selected for initial work on biology and hydromorphology • Rivers benthic macro invertebrates habitat quality elements • Lakes phytoplankton (cyanobacteria) macrophytes habitat quality elements • Transitional and coastal waters macrophytes macroinvertebrates introduced species
ROD - Reporting Obligation Database Keeps all environmental relevant reporting obligations for international organisations DD - Data Dictionary Contains the precise definition of requested data: • Content, Data structure and data elements • Definitions and methodologies • Format, data type, plausibility limits of elements • Data Exchange Modules (xls-templates, web-form)
Aggregation of requested data • Initially some countries did not want to report disaggregated data • Now becoming more accepted • Aggregated data: • more work for NRCs, less for EEA/ETC • data should be aggregated in a common way • summary statistics also required • Disaggregated data: • more work for EEA/ETC, less for NRCs • guarantees the same treatment/aggregation of data • more possibilities for statistical testing
Spatial aggregation/resolution of requested data • Station level • Location level • Linkages to surface water bodies • Groundwater sampling site to groundwater body • Stations from national/Federal monitoring networks • Supplemented by stations from regional/local monitoring networks
Annual update 2005 - timetable • Update request to NFPs/NRCs, 29 July 2005; • Deadline for delivery of data to EEA/ETC, 31 October 2005. • Delivery of Waterbase data for the EEA data service. January 2006.
Reference Waterbase - http://dataservice.eea.eu.int/dataservice/metadetails.asp?id=660 Reference - WATERBASE
Data Service - Waterbase • holds validated aggregated data • timely, reliable and relevant data from statistically stratified river & lake stations, from GW-bodies, transitional, coastal and marine waters, and water quantity • data comparable at European level • data used for indicator production http://dataservice.eea.eu.int
Eionet-Water River Stations
Eionet-WaterQuantity 2016 precipitation stations 1118 river gauging stations From 16 countries
Concluding comments • Eionet-Water is established and has had long-term support from many countries • Eionet-Water will have to adapt to (monitoring) changes relating to WFD • Will need data from surveillance and operational monitoring networks with contextual information to allow valid assessments • Will continue to need data on individual quality elements rather than just highly aggregated indicators (e.g. ecological status) for assessment of issues • Annual updates • Data and information from more monitoring stations needed to obtain representative overview of catchments and RBDs – WFD relevance! • Will progressively develop and become integrated into WISE
Concluding comments • Content of WISE needs to be agreed with countries and data users e.g. • Determinands • Statistical aspects • Spatial and temporal aggregation of data • Schedule for regular updating (based on existing Eionet-Water data flow) • Business rules on data handling and dissemination • Meta data to support the reported SOE data e.g. details of the monitoring station’s physical characteristics • Aspects of QA/QC and comparability
