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 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 Nitrites in groundwater
The map shows the mean annual concentrations of nitrites (NO2), 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 nitrites 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 Nitrates in groundwater
The map shows the mean annual concentration of nitrates (NO3), expressed as milligrams of NO3-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 nitrates 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 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.

GIS Map Application Phytobenthos in rivers
The map shows the ecological status or potential of European rivers, expressed using a specific biological quality element (BQE), namely phytobenthos, 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.

GIS Map Application Phytoplankton in lakes
The map shows the ecological status or potential of European lakes and reservoirs, expressed using a specific biological quality element (BQE), namely phytoplankton, reported by EEA member countries via WISE.

The assessment may be based by one or more samples taken during the year of reporting.

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.
