Re: Hippies? Chemicals unknow?
Maybe to those of you in the UK, others have that information....

A lot of this is carcinogenic and I wouldn't want this leaching into my ground water, which can and does happen:
Water contamination caused by fracking is well-documented. In December 2011, the US Environmental Protection Agency (EPA) released draft findings that link water contamination to hydraulic fracturing which have since been confirmed by later investigating and testing:
It's not only the poisoned water in the ground, the millions of liters of water that lorries have to haul into each 'play' (driving through your towns and neighbourhoods, destroying your roads and lanes, polluting your air) for every frack, that then get pumped up after a frack are saltier than sea water, contain substantial amounts of radioactive isotopes and are either stored in open pits (that have leaked), pumped back into the ground in spent wells or trucked out with lorries again and disposed of who knows where. In the USA they have been dumping this into rivers and creeks or 'legally' into sewage treatment plants (that have no technology to deal with either the salt content nor the radioactive elements) which ends up killing the bio cultures in those treatment plants and results in ALL the sewage and fracking water ending up in someones river/creek/canal in an untreated state.
You also have no idea of how many of these wells are needed. It's not just one in the vicinity of your back yard, there will be scores of them all over the county, being serviced by thousands of trucks and it will turn your pristine English countryside into this:
There won't be any point in singing 'Jerusalem' the next time you are at the Last Night of the Proms after the oil companies have wasted your land and drinking water.
Oh and while I'm at it, natural gas might be cleaner than coal but not fracked gas. You need to calculate the end to end cost which includes the thousands of truck/lorry trips back and forth to all the sites and the millions of cubic feet of Methane that is lost to the atmosphere due to current sloppy recovery and prevention practices in the industry, which is worse for the climate than CO2.
The enthusiasm for fracking by the apparent majority of readers on this site is appalling and disappointing. I would have expected that the above average intelligence gathered here would have spent some time on the web to read about these issues instead of displaying the levels of ignorant bliss currently on show. Start here to get some proper insight into what is really going on:
You might also question why the recovery period is 15-60 years. It seems that the fracking industry has also discovered a new income source with the licensing and sales of drilling rights. There has been a lot of 'pump and dump' with regards to hyping up possible reserves then selling the licenses for a huge profit to let some other subcontractor sucker frack a site only to find that it runs out of gas in a very short time, forcing them to either drill more wells in that area and frack more often.
A lot of the operations are running at a loss since the gas price has plummeted and quite a few have already gone broke as a result.
With parts of the world going to war over water in the future (http://phys.org/news/2012-09-world-crisis-priority.html) how can anyone in their right mind think that fracking is an acceptable risk to their drinking water?
