the chemicals used in fracking in the UK were relatively common, including compounds close to those found in household detergents and contact lenses, and were unlikely to cause problems of pollution. He also said the seismic activity that had been prompted by the Cuadrilla drilling near Blackpool was very small, and similar to that found in coalmining areas. However, he urged monitoring of drill sites and said that if further earthquakes caused problems in the wells drilled – for instance, by cracking the cement casing – then the wells would have to be reformed, a very expensive process.
