Assessment of the Biological Water Status: Diatoms
This dataset is part of Switzerland's National Surface Water Quality Monitoring Programme (NAWA), operated jointly by federal and cantonal authorities at around 100 monitoring stations. It provides the assessment of biological water status based on diatom investigations, carried out using the diatom module of the Modular Stepwise Procedure. Diatoms are microscopic algae whose community composition indicates nutrient levels and organic pollution in rivers and streams. The data support evaluation of ecological water quality across Switzerland and are maintained by the Federal Office for the Environment (BAFU).Within the National Surface Water Quality Monitoring Programme (NAWA), water quality is recorded jointly by the federal and cantonal authorities at around 100 monitoring stations. The biological water status is assessed on the basis of diatom investigations by the diatom module in the Modular Step…
