President Jacob Zuma says ‘Frack You’ to Karoo
The process that will be used to extract the gas – hydraulic fracturing, or ‘fracking’ – is carried out by drilling deep into the earth and injecting hundreds of millions of litres of a high-pressure mixture of water, sand and chemicals into shale rock, which in turn releases shale gas. The flow-back liquid from this process is highly radioactive.
