A Free State professor says there is a high risk that hydraulic fracturing, or fracking, in the Karoo could result in one of the biggest water pollution problems in the world, it was reported on Friday. “This is serious stuff. There will be trouble, and Shell and the other companies involved must take note,” University of the Free State professor Gerrit van Tonder told the Cape Times. Last July he had told Karoo farmers they need not fear water pollution from fracking, but his stance had changed since completing his latest research.
