The concentration of the tracers in the groundwater depends on the atmospheric concentration at the time of contact when the water fell as rain or snow, and the time since the last contact of the water with the atmosphere.
What is the age of water?
In the shallow aquifers you would expect young water, perhaps 50-100 years old, because its coming down as rain and flowing out towards the Nile Valley, said Sturchio. But in some of these aquifers, Mahmoud found water thats apparently 200,000 years old.
How long does it take rain to reach the water table?
The time it takes for surface infiltration to reach an aquifer as deep as 400 feet may take hours, days, or even years, depending on the rate of recharge. In some of the flood-irrigated areas, groundwater levels in nearby domestic wells rise within a few hours to days of flood-up.
What happens as water Ages?
You have less water on board to start with, so dehydration is more of a risk. With this loss of muscle you also lose a significant chunk of your “reservoir” of fluids as you age, meaning that dehydration when youre sweating a lot can occur more rapidly than it can for younger athletes.

How old is the oldest water in the ocean?
The worlds oldest known water was found in an ancient pool below Canada in 2016, and is at least 2 billion years old. Back in 2013 scientists found water dating back about 1.5 billion years at the Kidd Mine in Ontario, but in 2016, deeper investigation revealed an even older source buried underground.
Do you retain more water as you get older?
Heres Why. Researchers say that as people age, they need to drink more water to compensate for changes in their body temperature regulation. They say dehydration can cause a number of ailments, including muscle pain, fatigue, and heat exhaustion.
