The Saldur River has been a focal point for investigations since the 1980s for various biological and chemical laboratories of the Autonomous Province of Bolzano. There are four main measurement points along the 22-km river. One point serves as a regional and national biological water quality monitoring station. The EURAC Institute for Alpine Environment became involved in 2011, collecting additional physical, chemical and biological parameters. In addition to the four main measurement points, there are now sixteen additional points in the upper area of the river’s main tributaries.
