The UK’s lack of fracking regulation is insane

The UK’s lack of fracking regulation is insane by George Monbiot, August 31, 2011, The Guardian
There are two issues here: the chemicals injected into the rocks and the contaminants released by the fracturing. … Both the fracking fluids and the flowback fluids can contaminate water either through the cracks forced open in the rocks by the fracking process, or through drilling bores through aquifers. In the US this has happened repeatedly. The Tyndall Centre found that water supplies have been contaminated not only by the fracking chemicals and dissolved pollutants from the rocks, but also by gas bubbling out through the cracks.
