Water is probably the most important basic nesessity, and is often taken for granted. I have a couple of old wells on my property that I am going to have tested for safety, this summer. I'm thinking that this is an "Underrated Concern", and will get increased attention soon. The Ogalalla Aquifer, which feeds much of the ground water sources locally has been on a steady decline for many years. At some point this will effect agriculture, and contribute to an increasing demand on all fresh water sources. The prospects for West/Southwestern States seems even more serious considering the growing population. Conservation, or alternatives, or don't worry, that's the question.
