Waterbase - Groundwater

Note: new version is available!
Topics: ,
Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

European data

Waterbase-Groundwater: Microsoft Access database (2 tables)

Database contains all data tables. Detailed table definitions are displayed in the section with individual tables.

Waterbase-Groundwater: Bodies

The Bodies table contains physical characteristics and proxy pressure data of the WISE-SoE groundwater bodies. Each groundwater body has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Bodies with their respective Quality data. Each record has a quality assurance field. Its meaning is explained in the QA documentation which can be found in the "Additional information" section.

Waterbase-Groundwater: Quality

The Quality table contains data on nutrients, organic matter and selected pesticides in groundwater bodies. Each groundwater body has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the QualityWater data with their respective Bodies. Each record has three special quality assurance fields. They are explained in QA documentation which can be found in "Additional information" section.

QA documentation

Quality control documentation briefly presents ETC/Water and EEA activities focused on quality of Waterbase-Groundwater dataset and results of these activities. In addition warning is given on the use of certain records for analytical purposes.

Metadata

Additional information

Waterbase contains timely, reliable and policy-relevant data collected from EEA member countries through the WISE-SoE data collection (formerly known as Eionet-Water and Eurowaternet) process. WISE-SoE data collection selects validated monitoring data from national databases and adds information on the physical characteristics of the water bodies being monitored and on the pressures potentially affecting water quality. The added value of Waterbase is that data collected through the WISE-SoE data collection process are from statistically stratified monitoring stations and groundwater bodies and are comparable at the European level. Waterbase data are primarily used in the production of the EEA's indicator-based factsheets.
