there are a whole range of things which need to be said about this subject.
Firstly, there are some areas in the US where tap water comes virtually unpurified from local, sometimes private, wells. This isn't the case in the UK, so forget about your kitchen tap turning into a flamethrower.
Secondly, hydraulic fracturing is a long-established technique with a very wide range of applications and methods. Some of them leave a lot to be desired, some are very harmful and most do no harm at all.
What worries me is the lack of open-ness about the whole subject. When things go wrong in the oil industry they can go very wrong indeed.
