Figure Percentage of classified surface water bodies in different river basin districts (RBDs) holding less than good ecological status or potential, for rivers and lakes (top panel) and for coastal and transitional waters (bottom panel)
The figure shows percentage of the total number of classified water bodies. See the indicator specification for more details.

GIS Map Application Total phosphorus in lakes
The map shows the mean annual concentration of total phosphorus (TP), expressed as milligrams of TP per litre of water, observed in lakes and reservoirs 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 phosphorus includes all phosphorus components in water: phosphate, dissolved organic phosphorus and particulate phosphorus in algal and bacterial cells, as well as in mineral particles (e.g. clay). High or increased (compared to reference condition) concentration of total phosphorus represents a risk to normal functioning of lake ecosystems, causing eutrophication with potentially harmful or toxic algal blooms in the surface waters, reduced biodiversity, and oxygen deficiency in the bottom waters. The purpose of the map is to provide an overview of the mean annual value of total phosphorus in lakes and reservoirs 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 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 Water quality monitoring stations
The map shows the location of the water quality monitoring stations reported by EEA member countries via WISE SoE reporting. The purpose is to provide an overview of the spatial distribution and density of monitoring stations per water body category: rivers (including canals), lakes (including reservoirs), groundwater, and transitional, coastal and marine waters. The map displays all stations ever reported since 1992, so not all are currently active.

Daviz Visualization D source code Nutrient trend
The data series are calculated as the average of annual mean concentrations for groundwater bodies/river stations/lake stations in Europe. Only complete series after inter/extrapolation are included (see indicator specification). The number of groundwater bodies/river stations/lake stations included per country is given in the notes below the individual substance charts.

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment published Feb 2015
Since 2005, average nitrate concentrations in European groundwater have declined and in 2011, the mean concentration had almost returned to the 1992 level. The average nitrate concentration in European rivers declined by 0.03 milligrams per liter of nitrogen (mg N/l) (0.8%) per year over the period 1992 to 2012. The decline in nitrate concentration reflects the effect of measures to reduce agricultural inputs of nitrate, as well as improvements in wastewater treatment. Average orthophosphate concentration in European rivers has decreased markedly over the last two decades (0.003 milligrams per liter of phosphorous (mg P/l) or 2.1% per year). Also, average lake phosphorus concentration decreased over the period 1992-2012 (0.0004 mg P/l, or 0.8% per year). The decrease in phosphorus concentration reflects both improvements in wastewater treatment and the reduction of phosphorus in detergents.
