Mixed: water is a mixture of recent and vintage (greater than 1 TU to less than 8 TU).
Vintage: water entered the ground before 1953 (less than or equal to 1 TU).
Recent: water entered the ground since about 1953 (8 to 15 tritium units [TU]).
Symbol color indicates tritium age of water sample.
Tritium age
Not sampled for tritium.
