Shane, apologies for the delayed response. Not actively following this thread. But well casings are made from layers of cement and steel, they fail because the materials degrade over time. They are not immortal. Time may not be the short period for which fracking has been in use (it was, after all, only invented in 1948 or thereabouts), but the world is going to be around for a little longer than that (one hopes).

Here are a few more examples of the sorts of difficulties that can arise from this process:

This one is a bit of nice pedantics, to avoid addressing the problem...

If it is the well casing failing, not the fracking that causes the problem, then, sorry, it is the fracking that causes the problem - why? Because if they weren't fracking, they would not be installing the well casings.
