You almost certainly make it through most days without thinking about groundwater. All you know is that drinking water will come out of the faucet when you switch the manage, and there’s clean make (and beer!) at the grocery store. Some locations count on surface area drinking water to make these things come about, but many other folks pull their water from wells.
The “age” of the groundwater coming out of those wells may well sound like a weird thing to problem oneself with, given that the atoms in the molecules have clearly been listed here about as extended as the Earth has (and ended up born long just before that). But some groundwater was rainwater that seeped by way of the floor just previous 12 months, and some groundwater has been underground for above a million many years.
Regional groundwater reports might look into age, but no one has at any time tried to set jointly a world-wide picture since, properly, it’s really difficult to do. A new review led by the College of Victoria’s Tom Gleeson takes a whack at it, although, and shows us just how minor of our groundwater is significantly less than a hundred years aged.
