Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment published Dec 2010
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, and have remained relatively constant since then. The average nitrate concentration in European rivers decreased by approximately 9 % between 1992 and 2008 (from 2.4 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being almost halved between 1992 and 2008 (47 % decrease). Also average lake phosphorus concentration decreased over the period 1992-2008 (by 26%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflect 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.
