A Fitness for Use assessment of the waters of the Orange-Senqu Basin
This ‘Fitness for Use’ assignment forms part of the EU support to ORASECOM and provides an assessment of the suitability of use for both ground and surface water in the Orange-Senqu basin based on key water quality parameters. ‘Fitness for Use’ in the context of this report is actually an assessment of the possible impacts of known key water quality concerns on the major water users. It does not provide an overall assessment of the suitability of water for use, nor does it necessarily provide an assessment of the suitability for any particular use of water. It is intended only to provide a broad overview of the possible impacts of water in the basin on the use of water.
The outputs from this work are ‘Fitness for Use’ maps for each of the major water uses in the basin. This method has provided a consistent, robust and statistically defensible approach to assessing water use suitability at a high level. It also identifies areas where inadequate data (i.e. insufficient data values or range of variables tested) does not allow for an assessment to be made. The overall aim is to improve water resources in the four member states (Botswana, Lesotho, Namibia and South Africa) by promoting a common understanding of water quality issues from a transboundary perspective.
