The ongoing Water Research Commission-funded project, the South African Mine Water Atlas, will provide water managers with a comprehensive reference on the extent of mine-influenced water in the country, both on the surface and underground. The project is being led by consulting firm Golder Associates. Once completed, it will be the most comprehensive document of its kind in South Africa.
Mining has been an integral part of the South African economy for over 100 years. The industry employs close to 500 000 workers and contributes 18% of the country’s gross domestic product. The mining sector is also a large user of water in certain areas, with the water pollution problems associated with mining becoming well publicised in recent years.
Relatively small volumes of water are used by mining compared to other industrial sectors, but water is needed for extraction and concentration of metals and non-metallic minerals. Water is also used to generate electricity required for crushing ore, on-site processing, and smelting, refining and other aspects of treating resources to improve their properties. The crucial difference between mining and other industries is the severe and long-term nature of its impact on the aquatic and terrestrial environments – an impact which is widely acknowledged, but has not been mapped in South Africa.
“The Atlas will be a significant and timely contribution that can inform the implementation of commitments made in the past two years,” reports WRC Research Manager, Dr Jo Burgess. “Decision-makers will also be able to look to the atlas for background information and tools to assist in fulfilling commitments made in other recent events and declarations.” It is hoped that the general public and water professionals will also find this publication educational and beneficial.
While the first chapters will provide an introduction to mine-water and its geological, hydrological and legal context, the following chapters will provide the geographical foundations of water quantity, quality and distribution across South Africa. The Atlas will use various measures to illustrate South Africa’s hydrological characteristics by charting and mapping water resources at the provincial scale. Topics to be covered include water resources, water distribution, and the physical setting within which water is found. These features will be overlaid with a map of mining and mineral-refining activities in order to understand the locations at which surface and groundwater and mining collide.
In the next chapters, challenges and opportunities facing South Africa, as it strives to improve the quantity, quality and protection and use of its water resources, will be examined. Each of the mining-affected provinces will be presented by discussing the challenge, the situation, the constraints and the opportunities.
The final chapter will be a province-by-province look at water availability and withdrawals, as well as water use by the mining sector. In addition, two of the most important water issues in each province will be identified and discussed.
It is reported that all of those who have taken part in the initial stages of the project have been extremely positive and enthusiastic – both private and public organisations alike. A significant challenge of the project is getting access to the large amount of data residing with private consultants and the mining companies themselves. “This is where the WRC’s mode of operation in using reference groups to evaluate and monitor its research projects is crucial,” notes Dr Burgess. “If we didn’t have a collegial reference group full of people willing to share whatever data they can, the Atlas could not become a reality.”
To date, contributions and pledges have been received from the Department of Water Affairs, Coaltech Research Association, the Chamber of Mines, Golder Associates Africa, CSIR, Anglo Gold Ashanti, SLR Consulting, Glencore, Anglo Platinum, BHP Billiton, the Department of Environmental Affairs, and the Council for Geoscience. “All of these organisations are being extremely generous with in-kind support of this project, and are sharing as much as they can,” says Dr Burgess.
The project is set for completion in 2016.
