Resource Quality Services

RQS is a directorate in the Water Resource Information Management chief directorate under the Policy and Regulation Branch of the Department of Water Affairs.

Purpose of RQS

RQS provides national water resource managers with aquatic resource data, technical information, guidelines and procedures that support the strategic and operational requirements for assessment and protection of water resource quality. Functioning aquatic ecosystems and an adequate supply of usable water are fundamental to the survival and development of any nation, and particularly so for water-stressed countries like South Africa.

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 and microbiology.
For more information on other types of water quality information, such as municipal water supply and sewage, please follow the links on our Reports page.

Water quality analysis

Note that our laboratories only process samples registered on the national monitoring database. To look for private laboratories, please try this search:
