If there are still those among our number who believe that the water will be safe to drink once wholesale fracking gets under way in the UK perhaps they should take just two minutes to read the following: http://truth-out.org/news/item/22407-contaminated-water-supplies-health-concerns-accumulate-with-fracking-boom-in-pennsylvania#.UyREvduuFug.email
In the US of course, fracking activity is exempted from the Clean Drinking Water Act. Perhaps Cameron will make a similar exemption for his pals in the O & G industry.
If you are aware of doubters/deniers please circulate as widely as possible. Thank you.
