I'll front up here, I work in the Exploration and Production (E&P) business and have done now for over two decades. So to a degree I have a vested interest in these wells going ahead as it keeps me and my peer group in work. I also firmly believe that it is the most efficient, clean (yes, that's what I said) and effective way of ensuring our countries energy security for the foreseeable future.
The entire industry from a PR perspective is onto an immediate loser due to many historic events - and quite rightly so that there is a healthy amount of cynicism around the activities of large corporations.
Unfortunately media and activist groups have conveniently seized on the term 'fracking' and delighted in the various puns that can be made around it - and it's been very useful to certain groups in whipping up hysteria over what is pretty mundane gas extraction and to correct the OP, hydraulic fracturing has been used frequently in the UK historically and within the industry is almost so routine and unremarkable to not warrant any comment.
Yes, the initial drilling phase is fairly unsightly for a short period if I'm honest but no more impact than road improvements or a construction site might cause in an area for a while. I'd certainly much prefer to live close to a completed well site than wind turbines or a solar farm. Unless you were to go looking for it you probably wouldn't know it was there once commissioned.
The protection of aquifers and general safety for the general public is paramount, I don't have the space here to go into well casing design, down hole safety valves and and other safety features but as for pollution and radiation I would wager that farming and quarrying contribute far more in terms of chemical pollution and NORM (Naturally Occurring Radioactive Material) than these gas developments ever will. There won't be scorched earth, birth defects, catastrophic earthquakes or the ruining of groundwater.
What I do fear and think is more than likely is the fallout from professional agitators that are simply "anti" whipping up the well intentioned public into a frenzy of unnecessary protest via the use of what is effectively fake news to justify their arguments. Rational, calm, evidence based points of view are just being shouted down.
The UK leads the world in the technology and standards for safe and environmentally friendly hydrocarbon extraction and we export that knowledge around the world improving the way in which things are done in what historically has been a very messy business, this is something that we could and should be proud of and making the most of when the opportunity arises to use it at home. Don't get caught up in the protestors hype.
