I heard somwhere that it is possible to tell the "age" of groundwater (the 
year it was last on the surface of the earth) through a "signature" of an 
isotope left on the water when it was last on the surface.
I have a well / bore that is very deep and am curious to ascertain the 
"age" of the water.
can anyone help?
Thanks
Geoff
