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.

Indicator Assessment Emission intensity of domestic sector in Europe (WREI 002) - Assessment DRAFT created Dec 2014
Absolute decoupling of nutrient emissions from domestic sector and the population growth over the period of almost two decades (1990-2011) is observed in fourteen countries (Austria, Belgium, Czech Republic, Germany, Denmark, Greece, Finland, Ireland, Malta, the Netherlands, Norway, Portugal, Slovenia and Turkey). The actual extent of decoupling, and the differences in trends among countries, may be partially explained by different levels of numbers of inhabitants connected to tertiary wastewater treatment technologies When making the EU wide comparison of the extend of decoupling of nutrient emissions from population growth, the actual rate of population connected to different types of treatment (elaborated in the CSI 024) should be taken into consideration, and completeness of the data available on population connected to collecting systems without treatment. The status of the implementation of the UWWTD which protects the water environment from the adverse effects of discharges of urban waste water, the level of investment in the water and wastewater management ,as well as the status of the implementation of the Water Framework Directive (WFD) and Groundwater Directive may have an impact.   Furthermore household patterns as well as the household income level  affecting the production and composition of waste water should be considered as well. It is assumed that the use of actual data on loads discharged from wastewater treatment plants combined with the load values calculated for population not connected to the waste water treatment would add value to the decoupling indicator, as it would better reflect the real situation..

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.
