The world’s oldest water, which is locked deep within the Earth’s crust, just got even older.
According to BBC, the liquid was discovered deep down in a mine in Canada in 2013 and is about 1.5 billion years old.
But now, at the same site, University of Toronto scientists have found a deeper source of water that is at least 500 million years more ancient.
The work was presented at the American Geophysical Union Fall Meeting in San Francisco.
This new investigation led by Dr Oliver Warr, from the University of Toronto, found water at a depth of nearly 3km.
And tests have revealed that it is at least two billion years old.
