30 Years of the TNMN: Guarding the Danube’s Water Quality Amidst EU Innovation
As the TransNational Monitoring Network (TNMN) marks its 30th anniversary, it stands as a model of international cooperation in water quality monitoring. Since 1996, the TNMN has provided a structured, long-term view of pollution and water quality in the Danube River Basin, tracking chemical and biological parameters across more than 100 monitoring locations. Its data not only informs local and national policies but also supports compliance with the EU Water Framework Directive.
