Highlight PostScript document Europe's water information at your fingertips
Our demand for water and wastewater discharges, often have a substantial impact on the quality and quantity of freshwater resources. On World Water Day, 22 March, the European Environment Agency (EEA) and partners presented a new and improved version of the web portal Water Information System for Europe (WISE).

Publication Europe's ecological backbone: recognising the true value of our mountains
Europe's mountain areas have social, economic and environmental capital of significance for the entire continent. This importance has been recognised since the late 19th century through national legislation; since the 1970s through regional structures for cooperation; and since the 1990s through regional legal instruments for the Alps and Carpathians. The European Union (EU) first recognised the specific characteristics of mountain areas in 1975 through the designation of Less Favoured Areas (LFAs). During the last decade, EU cohesion policy and the Treaty of Lisbon have both focused specifically on mountains.

Press Release C source code header EU bathing water quality remains high
Clean bathing waters are vital for key economic sectors such as tourism and for plant and animal life. The annual bathing water report presented by the European Commission and the European Environment Agency shows that 96 % of coastal bathing areas and 90 % of bathing sites in rivers and lakes complied with minimum standards in 2009. It also describes where to obtain detailed and up-to-date information on bathing sites.

Press Release C source code header Bathing water quality remains high around the EU
The quality of bathing water across Europe declined slightly between 2009 and 2010, but the overall quality was still high. More than nine out of 10 bathing water sites now meet the minimum requirements.

GIS Map Application Macrophytes in lakes
The map shows the ecological status or potential of European lakes and reservoirs, expressed using a specific biological quality element (BQE), namely macrophytes, reported by EEA member countries via WISE. The ecological status class is assessed by each country according to their national classification system, following the principles established by the Water Framework Directive (WFD). The assessment may be based by one or more samples taken during the year of reporting. The map displays the latest reported information under the WISE SoE reporting, so the year of reference may vary. Note that under the WFD reporting, the ecological status or potential based on all BQEs combined is represented by the BQE with the worst class - the "one-out-all-out" principle - which does not apply here, given that only one BQE is represented and that the reporting is done annually. The purpose of the map to enable the user to compare values per country or per monitoring station, depending on the scale of visualisation.

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 Orthophosphates in rivers
The map shows the mean annual concentration of orthophosphates (OP), expressed as milligrams of PO4-P 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). High or increased (compared to reference condition) concentration of phosphates represents a risk to normal functioning of river ecosystems, causing eutrophication with potentially excessive growth of benthic algae or other aquatic vegetation, oxygen deficiency in the bottom substrate and reduced biodiversity. The purpose of the map is to provide an overview of the mean annual value of orthophosphates 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 1993 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.

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.

Highlight More than half of EU surface waters below ‘good’ ecological status
Water pollution and physical modifications are still affecting the ecology of many of Europe’s lakes, rivers, transitional water bodies and coastal waters. These problems are likely to prevent the water bodies reaching ‘good’ status by 2015, a target set by the EU’s Water Framework Directive (WFD).
