Oldest water ...2 Billion years

Oldest water in the world found in Ontario by U of T scientists
2 billion-year-old water won't kill you, but would taste 'absolutely disgusting,' U of T researcher says

a lttle water with your whiskey sir....?

err maybe not

Exotic chemical cocktail

The water is up to eight times saltier than seawater, and likely has some trace metals in it, he said.

It barely mentions life, wouldn't it be possible for there to be some kind of remains that could be identified, or would it have gotten filtered out? There is a lot of life in rocks at that depth, or at least to 2 klicks down, if I remember correctly. I've seen in a couple of places at least that the biomass in all the rock could exceed that on the surface. Anyone know if this is correct?

What is the radiation level? If it contains post-nuclear age radiation contamination levels then the 2 billion year figure may be called into question. :ask:

The early atmosphere
Scientists believe that the Earth was formed about 4.5 billion years ago. Its early atmosphere was probably formed from the gases given out by volcanoes. It is believed that there was intense volcanic activity for the first billion years of the Earth's existence.
The early atmosphere was probably mostly carbon dioxide with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans.

http://www.bbc.co.uk/science/earth/earth_timeline/late_heavy_bombardment
In other words, water was being brought to the earth as it was forming, at about 4BnYa.

EDIT: If all they find if water up to 2Bn years old, perhaps they should keep looking!

Timmins is hard rock mining...no sedimentary rocks so this pocket would not have been ever on the surface .....would have been part of the Canadian Shield and the very oldest part at that.

Don't you mean the oldest part of the crust?
There seems to be a contradiction between this 2BnYr result and the idea that the late heavy bombardment (LHB) brought water to the planet about 4Bn years ago, as described in my link above. Are they claiming that the heating of the planet during LHB drove all the older water out and away from the earth forever?

EDIT: Didn't that process simply put a lot of water temporarily into the atmosphere, fromn where it would have recondensed at the end of the LHB?

Has anyone determined the age of the water that comes out with the magma from erupting volcanoes, because that could be older than any crustal water.

Um the Canadian Shield last time I checked was part of the crust.

Here is a good read and the conclusion seems to point to water as part of the original formation.
