The following report from The Guardian dated 03/08/2013 paints a devastating picture of one UK shale gas 'exploiter'. Always, it is an 'oversight' or the fault of 'the contractors', never actually them/their fault.
If we are to believe that fracking can be done 'safely' ( sic ) with 'proper regulation' then operators
( and their political masters ) will have to try a great deal harder than this: http://www.theguardian.com/environment/2013/aug/02/fracking-cuadrilla-trespassed-private-land
Depressing to say the least.
