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: Bodies

The Bodies table contains the physical characteristics of the Eionet-Water 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 and Pressures data.

Waterbase-Groundwater: QualityWater

The QualityWater 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 and Pressure data.

Additional information

Waterbase contains timely, reliable and policy-relevant data collected from EEA member countries through the Eionet-Water (formerly known as Eurowaternet) process. Eionet-Water 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 Eionet-Water 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.
