I read with interest the conflicting views of Nick Riley and Chris Jack concerning fracking in the UK. Fracking is a highly controversial subject and one which has attracted a lot of media attention.
I have to agree with the views of Chris Jack that there are legitimate and convincing concerns about fracking that have not yet been resolved. Some test boreholes have been drilled but the results have not yet been revealed or certainly not to the general public. My view is that there are risks and the geology and groundwater regime of areas where fracking is proposed needs to be carefully mapped and studied. The presence of any aquifers in the vicinity would obviously be a major concern.
