Grand CommitteeI thank my noble friend for giving way. I have listened carefully to his arguments and would like to ask him whether he is excluding the other risks associated with fracking. Whether or not there are earthquake risks, surely we have the pollution of the groundwater, the toxic chemicals being released, the ground level ozone, air pollution and the use of large volumes of water in a country which had water shortages not that long ago and indeed where the geography seems to be rather different from that in other countries where fracking has been so successful.
I have good news for the noble Baroness, because those issues were covered in Shale Gas Extraction in the UK: A Review of Hydraulic Fracturing, produced by the Royal Society and the Royal Academy of Engineering. We are all constantly urged to follow the science, so let us follow the science in that review. She discussed water, and according to the review:
“Overall water use is important. Estimates indicate that the amount needed to operate a hydraulically fractured shale gas well for a decade may be equivalent to the amount needed to water a golf course for a month”.
That seems something with which we can probably cope. She then discussed the possible results leading to the pollution of aquifers. The review says:
“Concerns have been raised about the risk of fractures propagating from shale formations to reach overlying aquifers. The available evidence indicates that this risk is very low provided that shale gas extraction takes place at depths of many hundreds of metres or several kilometres.”
In the UK’s Bowland shale, it would be kilometres deep. The review continues:
“Geological mechanisms constrain the distances that fractures may propagate vertically. Even if communication with overlying aquifers were possible, suitable pressure conditions would still be necessary for contaminants to flow through fractures.”
When you have a kilometre or more of stone—impermeable rock—bearing down, you could not get a better seal.
Nevertheless, we do not have to worry about scientific analysis and theory, because we have practical experience. Over a million wells have been fracked in North America; not a single one has resulted in a building falling down from tremors or in a single person being poisoned by contaminated aquifers. So we are bound to conclude that lots of people have been spreading the sort of scaremongering that would make anti-vaxxers blush—even Andrew Bridgen would probably blush if he heard some of the stuff that has been put out by the friends of the noble Baroness, Lady Bennett, at their various camps around every conceivable attempt to get fracking going. We should rely on the science and the scientific reports and regulate the industry well, as we have done in the past.
