Water-quality measurements from the GEMStat archive. Explore stations, parameters, countries and annual trends.

How the data was collected

UNEP GEMS/Water Global Freshwater Quality Archive · GEMStat · ICWRGC / BfG

Method

The dashboard shows medians by station, year and parameter. Mass concentrations are normalised to compatible units. Sediment units, missing parameter codes and unusable measurements are excluded and counted in the processing report. Parameters follow the selection in the reference explorer snapshot.

Data quality

Colours describe the distribution of this parameter, not a regulatory water-quality classification. The original CSV files retain measurement flags and quality information.
