This is a cross-post of mine from EU Referendum; one that is best shared:

Anyone in need of a Shale Gas reality check, particularly if they have been exposed to the GasLand video agitprop should find the following web links useful (Energy-in-Depth):
All you need to know about fracking from overview and history to general technical details such as fluid composition:
GasLand debunked:
FAQ of fracking, including some basics of legislation and regulation:
Poster of fracking fluid composition:
A timeline:

Well [intended?] that should keep most people busy and well-informed; but don't forget there is much much more on that website.

Below is a post I made on BishopHill Blog and aimed at UK residents:

Quote:I've not seen the whole Gasland film but I did view the trailer. It is simply propaganda. Not only that, but to suggest the claimed issues (as seen in the video) might happen in the UK, particularly at the Blackpool (Bowland Shale formation) is stretching the imagination beyond reason.

The main fright tactic is to show gas in the water supply. It certainly looks impressive. However in the UK it is extremely unlikely for two basic reasons. Firstly, well over 99% of all water comes from the mains. Whilst water some is extracted from boreholes (I don't have local knowledge of the region's supply structure, so there may be none), it always goes through many levels of treatment and quality assurance. Any problem would be picked up very quickly and remedial action taken.

Secondly, the target shale is at least 1000m down. Typical domestic boreholes for water are less than 100m and more normally less than 70m. The chances of any fracturing (by hydraulic or any other non-natural process) from the shale depth to that of the borehole is miniscule. Without a path, the fluids cannot migrate. The fracking fluids and any gas released will not be able to reach any aquifer hundreds of metres above.

Boreholes are always lined and cemented-in to prevent flow and contamination between strata. Great care is taken to avoid damage to aquifers and to circumvent flow from them. Water in the gas pipeline is no laughing matter. Indeed the industry is extremely conscious of all these issues and perfectly capable of addressing them with well-established methods.
"Correlation is NOT Causation"
In the UK energy suppliers often sell other products. As a colleague pointed out, with water and gas coming down the pipeline, maybe they could supply power and internet access down it too? Just think of the cost savings.
