The process of fracking begins drilling deep holes into the ground, at depths of 2 km or more. Then millions of liters of a water, chemical, sand combination are inserted into this hole at really high pressures in order to fracture the shale rock and release natural gas. But along with the natural gas comes out thousands of liters of contaminated water known as ‘flowback’. Flowback contains the original fracking chemicals along with other heavy metals and radioactive material that had been peacefully sleeping in the shale before these drillers came by and woke them up.
