No risk of fracking poluting underground water resources – scientists say

Despite claims made by green campaigners assisted by celebrities – most recently Emma Thompson – scientists believe that hydraulic fracturing poses no real danger to underground water supplies. These are the findings of a new research carried out by Glasgow University’s School of Engineering.

In a paper published in the journal Earth and Environmental Science Transactions of the Royal Society of Edinburgh, Professor Paul Younger insists that fracking on a large scale is unlikely to affect underground aquifers. He was led to this conclusion after carrying out a detailed study of the Selby coalfield in Yorkshire.

Prof Younger said: “In order for aquifers to be contaminated, an interconnection between a fracture and an aquifer would need to be created during the fracturing process.”
“Firstly, shale gas developers have a major vested interest in preventing this from happening, since it would result in a great deal of expense to pump it away before gas production could begin. Secondly, we can see from Selby, which is located at less than half the depth of proposed shale gas fracturing zones, that total isolation from aquifers is entirely likely.”

He added: “There may be other reasons for opposing the use of indigenous gas resources, but aquifer pollution due to fracking at great depths is not one of them.”

The work was partly funded by the Natural Environmental Research Council and the Engineering and Physical Sciences Research Council.
