Assessment of the Chemical Water Status: Phosphate
This dataset is part of Switzerland's National Surface Water Quality Monitoring Programme (NAWA), under which water quality is jointly recorded by federal and cantonal authorities at around 100 monitoring stations across the country. It provides an assessment of the chemical water status based on phosphate concentration, following the Physicochemical Water Quality assessment methodology. The data is published by the Swiss Confederation, specifically the Federal Office for the Environment (BAFU), and offers a nationally consistent view of nutrient pollution levels in Swiss surface waters over time and across monitoring sites.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 chemical water status is assessed on the basis of the phosphate concentration by the “Physicochemical Water Quality…
