...Again, to be clear, a 1 year half life does not mean that it will be gone in one year. It means that the chemical is reduced by half each year.

This is all assuming laboratory conditions. In the real world, I would expect some chemical to migrate. Perhaps through migration of water horizontally, or vertically. I'm not sure what happens to the chemical after uptake in plants. Some chemicals move through evaporation, although it appears that the vapor pressure of aminocyclopyrachlor is pretty low (this may not be true for its methyl ester formulation though).
Thanks rlitman for helping explain the chemical lifespan in more detail. Very helpful.
