We will be in touch
Been thinking about this for a while, it came up in conversation during drinks. I believe that wast water is apparently the deepest and like most waters is filled at various points and exits elsewhere. Questions arose regarding how old is the water at the bottom? How is the age of water calculated? Does the flow in pass over resident water or just mix with it! As said we had been drinking but interested too know. Any thoughts anyone! Over to the hive.
how old is the water in your tap?
matter cannot be destroyed so everything around you, all the elements that go into making all physical matter including yourself are as old as the Earth.
Interesting thought jekkyl. Deeper than Was****er.
or possibly older?! when was all matter created?
One common definition for water age scientifically (in the context of oceans) is the time since it was last in contact with the air. Roughly 1000y for the deep ocean. No idea what it might be for a well-stratified lake.
And isn't colder water heavier?
There are trenches in the oceans that are like "well cold" at deep depths, unaffected by tides or wind, guess that water has been around for many millennia, yet the top (say) 50 mtrs is affected by tide, wind and sun and rain, therefore would move around.. but still might be really old water.
Good question.

But we cans til ask how long has that molecule been in that lake?
