Resource Quality Information Services Data and Reports

A selection of data and reports related to water.

Water quality results

The national monitoring programmes mostly monitor "raw" surface water quality in rivers and dams and produce long-term trend reports and visualisations of, for example, chemistry, eutrophication, microbiology and ecosystems.

Browse water chemistry time-series graphs using Google Earth or text lists.

You may also request archived "raw" water quality data from the Resource Quality Information Services national monitoring programmes for specific rivers and dams by E-mail.

For retrospective studies, download an inorganic water chemistry dataset of rivers, dams, and lakes in South Africa, prepared from the DWS data, 1972-2011, by North-West University.

The DWS NIWIS dashboards integrate water-related data from many sources.
