GIS Map Application Total phosphorus in lakes
The map shows the mean annual concentrations of total phosphorus (TP) as mg/L TP in European lakes and reservoirs measured at Eionet-Water Lake monitoring stations during 2011. Total phosphorus includes all phosphorus components in lake water: phosphate dissolved organic phosphorus and particulate phosphorus in algal and bacterial cells, as well as in mineral particles (e.g. clay). For most countries the concentration values are based on measurements over the whole year, but for some countries the annual mean actually represents only the growing season (due to ice cover in winter).

Figure Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2008 in different sea regions of Europe
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations per region is given in parentheses.

Indicator Assessment chemical/x-pdb Emission intensity of domestic sector in Europe (WREI 002) - Assessment published Feb 2014
Absolute decoupling of nutrient emissions from domestic sector and the population growth over the period of almost two decades (1990-2009) is observed in thirteen countries (Austria, Belgium, Czech Republic, Germany, Greece, Finland, Ireland, Switzerland, 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..

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2013
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2005. On average, the nitrate concentration in European rivers declined by 0.5 mg N/l over the period 1992 to 2011 (20% relative to the average concentration), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades- On average concentrations declined by 0.08 mg P/l between 1992 and 2011 (72% decrease relative to the average concentration). Also average lake phosphorus concentration decreased over the period 1992-2011 (on average by 0.008 mg P/l, or 27% relative to the average concentration). The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.
