Controversial use of Hydrofluoric Acid as Part of Fracking Process in Wressle, Yorkshire
The proposed fracking in Wressle is set to use a technique known as duo frac. One of the involved stages is acidisation, this uses hydrofluoric acid (as well as other chemicals) to dissolve material collected at the drill head. The Environmental Agency has stated that this is the first time hydrofluoric acid has been used for onshore drilling. There are concerns that these chemicals, as well as hydrocarbons, could contaminate ground water and affect the neighboring steel production.
