Studies have revealed that hydraulic fracturing of rocks underground for shale gas otherwise known as 'fracking' could be responsible not just for minor earthquakes close to where the fracking goes on such as what happened earlier this year near Blackpool, but also the cause of a number of lakes and reservoirs seeing their water levels gradually lowering in spite of regular rainfall. There has also been evidence of coloured water further downstream from fracking sites - possibly chemicals used in the fracking process getting into the main water supplies.
Geologists have studies the rock formation and concluded that new underground rivers are forming along the cracks and over time will pose a threat to land and properties close to where the fracking has taken place. The immediate effects will not be seen while the fracking goes on but over the years (something like in about twenty years) there will be evidence of something going on underground and by the turn of the century it may not be safe to build properties with these human-induced underground rivers.
Geologists would like to make it clear that natural rivers pose no threat since nature does things properly - it is when man interferes it creates greater risks and so unless nature heals these scars there is a great risk of unstable land close to fracking sites with a radius of about five miles.
Protestors at various sites in the UK have been getting rather fracked-off with all these rigs popping up around the beautiful countryside as well as concerns over the damage done - not just to the earth but village life and the concern over the chemicals used.
A spokesperson for FrackingGood a company involved in several sites in the UK including Lancashire and The Vale of Glamorgan in South Wales said that this was early days and they will do what they can to ensure they don't disturb the natural structure of the geology and rocks where they do their fracking. But protestors believe that doesn't say how much damage could be done in the areas where fracking has taken place and the companies get instructed to frack off by the authorities over safety concerns.
