This paper describes the progress made by the Department of Water Affairs and Forestry in the development of documented water quality guidelines for aquatic ecosystems in South Africa, which will be able to take into account local and site-specific conditions. Proposed guidelines for toxic substances, nutrients and physico-chemical variables are described.
