description: This dataset provides assessments of chemical water status based on nitrite concentration, produced under Switzerland's National Surface Water Quality Monitoring Programme (NAWA). Water quality is jointly recorded by federal and cantonal authorities at around 100 monitoring stations across the country. The assessment applies the Physicochemical Water Quality module to classify nitrite levels in surface waters, contributing to the systematic evaluation of chemical water status nationwide. The data is published by the Swiss Confederation, specifically the Federal Office for the Environment (BAFU), as part of its broader environmental monitoring activities.
