Chemists have long recognized water as a substance having unusual and unique properties that one would not at first sight expect from a small molecule having the formula H2O. It is generally agreed that the special properties of water stem from the tendency of its molecules to associate, forming short-lived and ever-changing polymeric units that are sometimes described as "clusters". These clusters are more conceptual than physical in nature; they have no directly observable properties, and their transient existence (on the order of picoseconds) does not support an earlier view that water is a mixture of polymers (H2O)n in which n can have a variety of values. Instead, the currently favored model of water is one of a loosely connected network that might best be described as one huge "cluster" whose internal connections are continually undergoing rearrangement.

All water tastes the same, Right? Actually wrong.  While many people think of water as a tasteless liquid that is necessary for survival, the truth of the matter is that water does vary in taste considerably due to many factors.

Water is absolutely essential to life.  In fact, it can make up to about 70% of our body weight.  Although water is important in our daily lives, many of us still don’t consider just how important slight changes can be to our daily drinking water supply.
