National Chemical Monitoring Programme for Surface Water

National Water Resource Quality Status Report: Inorganic Chemical Water Quality of Surface Water Resources - The Big Picture :

This 2002 report provides information on the major inorganic chemical water quality constituents of surface waters across South Africa, for water resource managers, scientists, decision-makers, and the public. It provides an overview of the status of surface chemical water quality according to the water quality requirements of two water user sectors, namely, domestic water use and irrigated agriculture water use. See the Executive Summary (PDF) and Full Report (HTML index) for further details.
