Data Waterbase - Lakes
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
Located in Data and maps Datasets
Data File QA documentation
Quality control documentation briefly presents ETC/ICM and EEA activities focused on quality of Waterbase-Lakes dataset and results of these activities. In addition warning is given on the use of certain records for analytical purposes.

Data Waterbase - Emissions to water
Emissions to water are an important element (describing the pressure) in assessment of the state of Europe’s environment (SoE). This database contains data on emissions of nutrients and hazardous substances to water, aggregated within River Basin Districts (RBDs), in the EEA member countries. The reporting process, endorsed by the Water Directors, and this publication of the data, enables all stakeholders to use the data and contributes to streamlining with other reporting processes.

GIS Map Application Ammonium in rivers
The map shows the mean annual concentration of total ammonium (TA), expressed as milligrams of N-NH4 per litre of water, observed in river monitoring stations and reported by EEA member countries via WISE. For most countries the mean annual value is based on observations over the whole year, whereas some countries only collect samples during the growing season (due to ice cover in winter). Total ammonium concentration can increase as a result of discharges from waste water treatment plants, industrial effluents and agricultural runoff. Ammonium exerts a demand on oxygen in water as it is transformed to oxidised forms of nitrogen. It is also an important nitrogenous fertilizer for aquatic plants, so it can cause eutrophication and indirectly reduce the dissolved oxygen due to increased BOD. In addition it is toxic to aquatic life at certain concentrations in relation to water temperature, salinity and pH. For example ammonium hydroxide in water is extremely toxic to fish and aquatic life at elevated pH levels. It can also pollute drinking water and bathing water. The purpose of the map is to provide an overview of the mean annual value of total ammonium in rivers across Europe and to enable the user to compare values per country or individual monitoring station, depending on the scale of visualisation. Historical data since 1993 can be displayed using the time slider.

GIS Map Application BOD in rivers
The map shows the mean annual value of BOD observed in river monitoring stations since 1993, reported by EEA member countries via WISE. BOD (Biological Oxygen Demand or Biochemical Oxygen Demand) is the amount of dissolved oxygen, expressed in milligrams of oxygen per litre of water, consumed by micro-organisms to decompose the organic matter present in water. BOD is commonly reported as BOD5, the amount of oxygen consumed over a 5-day period of incubation. Some countries report BOD7, the amount of oxygen consumed over a 7-day period. For comparability, the values of BOD7 are converted to BOD5 (BOD7 = 1.16 BOD5). Large quantities of organic matter (microbes and decaying organic waste) in water are a potential risk to aquatic ecosystems and human health. The reduction in the amount of dissolved oxygen as a result of the decomposition of organic matter can endanger aquatic life through asphyxiation and disrupt the ecological balance of the water. Organic matter can also pollute drinking water and bathing water. High levels of BOD can indicate such organic pollution. The purpose of the map is to provide an overview of the mean annual value of BOD in rivers across Europe and to enable the user to compare values per country, River Basin District (RBD) or individual monitoring station, depending on the scale of visualisation. Historical data since 1992 can be displayed using the time slider.

GIS Map Application Water quality monitoring station density
The map shows the density of water quality monitoring stations, reported by EEA member countries via WISE SoE reporting. The density of river monitoring stations is represented per national River Basin District (RBD). Note that the set of monitoring stations used by Member States to assess the chemical and ecological status of river water bodies under the Water Framework Directive may not be the same set of stations used for the annual WISE SoE water quality reporting. Historical data since 1992 can be displayed using the time slider.

GIS Map Application Ammonium in groundwater
The map shows the mean annual concentrations of ammonium (NH4+), expressed as milligrams of NO2-N per litre of water, observed in groundwater monitoring stations and reported by EEA member countries via WISE. The purpose of the map is to provide an overview of the mean annual value of ammonium in groundwater across Europe and to enable the user to compare values per country or per groundwater body, depending on the scale of visualisation. Historical data since 2000 can be displayed using the time slider, and different horizons can be selected using the layers menu.
