JOINT DANUBE SURVEYTechnical Report of the International Commission for the Protection of the Danube River September 2002 Joint Danube Survey 1
The Joint Danube Survey 2001 was carried out by the ICPDR and is the most homogenous analysis of the water quality and the ecological status of the Danube River. Over 140 chemical and biological parameters were analysed and over 40.000 laboratory results were generated.
Water Quality
Water quality in the Danube has improved over the years, but there is still much work to be done to meet the region’s goals for water status. To improve the water quality, an ambitious programme of measures for the whole Danube River Basin District has been agreed under the EU WFD. To assess trends in water quality, the ICPDR oversees the TransNational Monitoring Network (TNMN). The network carefully monitors physical, chemical and biological conditions in the Danube and its tributaries, and provides in TNMN Yearbooks an annual overview of pollution levels as well as long term trends for water quality in the basin.
