Given that we have a chalk aquifer below us and then nothing that would act as a cap rock between it and the (potential) gas bearing formation, then yes, fracking would be the name of the game for gas extraction.'Fracking' is fracturing the shale gas formation by injecting very high pressure water mixed with a few chemicals, colloquially called 'slick water'.  The chemicals are detergents and acids which penetrate and break up the shale rock to allow all the trapped gas to run to the wells. It's the chemicals that cause the problems because if you inadvertently run a fracture up to the aquifer you end up with drinking water that is bubbly, acidic and full of detergents. ie not very good.  When you talk about risk, then this is really the only risk there is.  There is no problem with subsidence because the gas is replaced with high pressure water. There's also (next) to no risk of blowouts because the gas pressure is nothing like the high pressures we get from normal reservoirs.There would be disruption though, caused by the drilling site itself which would run 24hrs a day and use high speed diesels for power needs, plus the large number of tankers needed to ship in the chemicals and large number of trucks for drill pipe etc. Plus the drillers themselves - generally an unsavory bunch at the best of times (snigger, personal experience)You'd have to make your own mind up on the balance between the negatives and the positives. The positives of course are that natural gas is the greenest of the fossil fuels, and we all use it for heating and electricity generation so why should we complain about having it in our back yard.  For the negatives then I'm not the best person to ask.

Coming to waterway near you if we don't take action...Greenpeace sent this mail out today and it looks like Cameron is pushing forward with plans to frack anywhere, Nicola-----Wow -- David Cameron's plan to force fracking on us just hit a new low.The prime minister wants to change the law to allow fracking firms to drill under our homes. But now he's fast-tracking his plan through Parliament at a blistering rate.Only a HUGE backlash from our MPs can stop him -- and we've got just days to make it happen.Can you forward this email to a friend and ask them to sign the petition? If thousands more of us join in, our MPs will think twice before voting for Cameron's plan.Your friends can sign here: https://secure.greenpeace.org.uk/fracking-vote-2Thanks to public pressure, fracking bans are already in place in France and Bulgaria. And just last month New York joined the list of US states that have taken action to stop the industry.Despite massive opposition, David Cameron is determined to bring fracking to the UK. And right now, he's on the cusp of changing our laws to make it easier to roll it out.But the prime minister's plan can't get the go ahead without approval from MPs -- and inside the halls of Westminster, a backlash is starting. The Scottish National Party and the Green Party have spoken out against Cameron's plan. Amongst Labour and the Lib Dems voices of dissent are on the rise, whilst Conservatives are feeling increasingly nervous as we approach the election. MPs will vote on the issue before the end of this month -- that's far earlier than expected and a move that would slash the time for debate and scrutiny.146,000 people have already asked our MPs to vote against Cameron's plan, but if we're going to make this huge, we'll need as many as possible of us on board.Please ask your friends to sign the petition to all MPs: https://secure.greenpeace.org.uk/fracking-vote-2We're piling the pressure on before the crucial vote. Alongside our friends at 38 Degrees and Friends of the Earth, teams of volunteers will visit several MPs at their offices -- handing over our petition face-to-face. And then next week we'll double our impact by sending letters to every single Westminster MP, telling them who's signed the petition in their constituency and calling on them to vote down Cameron's plan.Together we’ll make this petition unmissable, so please forward this email to your friends today.They can sign at: https://secure.greenpeace.org.uk/fracking-vote-2Let's keep going!
