The resource was discovered by the Council for Geoscience (CGS), a statutory Science Council reporting to the Minister of Mineral Resources, while conducting research on the development of shale gas.
The preliminary results indicate that the water is of good quality for drinking and other uses.
Mineral Resources Minister Mosebenzi Zwane says the much-needed water resource brings about a huge relief to the drought-stricken Beaufort West and the Western Cape Province.
Shale gas resources
Minister Zwane directed the CGS to conduct a baseline study to enable government to make informed decisions on the balance of science-based evidence on the development of shale gas resources in the vast Karoo Basin of South Africa.
“A geoscientific team from the CGS has concluded the geological mapping, geophysical survey (both ground and air-bourne), hydrogeological monitoring (which is continuous until the drilling of a deep borehole +3km) and environmental screening.
“The water boreholes intended for the baseline studies and future monitoring of the water resource have also been used to pilot the casing methods to ensure maximum protection of the water resource in the Karoo,” the department notes.
Minimising drilling impact
The final characterisation of the five boreholes will be concluded by the end of January 2018.
“The research work will be done in stages in order to minimise the potential impact of drilling to the environment.
“In due course, the borehole will be officially handed to the municipality to ensure that the people of Beaufort West and nearby communities can have access to water,” the department says.
