Indicator Assessment Oxygen consuming substances in rivers (CSI 019/WAT 002) - Assessment published Feb 2015
Concentrations of biochemical oxygen demand (BOD) and total ammonium have decreased in European rivers in the period 1992 to 2012 (Fig. 1), mainly due to general improvement in waste water treatment.

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.
