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.
