I actually thought this thread was started as a spoof but after reading it I guess it is genuine. The aquifer is nothing more than the underground water supply. In some areas such as the one I live in the aquifer stretches over forty miles in length. At some point the rainwater and surface water descends and becomes part of this underground "lake" and is in turn returned to the surface in the form of springs, creeks, lakes etc. There are in some places (Florida) where sink holes open up and swallow houses, roads etc. The old saying "Poo happens" comes to mind. But to put your mind to rest I doubt that bringing in all the additional building supplies is going to speed up the rate the state is sinking. There will come a day when there will need to be a levee system (as in Holland) to keep things habitable but that will be several thousand years or so into the future. I might suggest that you find a new topic to be concerned about and put this one to rest. Respectfully Geese.
