Age Is Decay Against Mixing
The claim
The apparent age of groundwater is set by the ratio of tracer decay rate to mixing rate, so a mixed sample reports an age that no water in it has.
01Mechanism
Age tracers average over a distribution; mixing biases the mean.
02Prediction
Bias should track the ratio.
03Refutation
Bias tracking tracer half-life would remove mixing.
