   Bottled water companies often brag 1 about the purity of their drinks. Just imagine if they found a water source that's been cut off from the outside world for well over a billion years. Well, scientists have discovered just that, in isolated 2 reservoir 2.4 kilometer underground in Ontario, the examined fluids seeping 3 out fractures in a mine, and found particular ice tubes of noble gas xenon. By comparing the ice tubes to those known truth being in the ancient atmosphere, the researchers dated that the slowest escape water to be at least 1.5 billion years old. Some of oldest known. As the rocks around the water are 2.4 billion years old, the water may be too. The finding is in the journal Nature. The liquid also contains the dissolved gases such as Methanol Hydrogen, which in some lis* environments support microbial life. The discovery of any microbes will support the hope that similar underground life might exist on Mars and elsewhere. Insure, this ancient water could hold gas, microbes and hints about extra treasure* of life, so let's for a go finding out how it tastes.
