    I don't think its a definite time! It depends on soil. After a heavy rain, some
    soils could still be saturated. So I will go for at least 2 days.

    What where the other answers?

    I have not been able to find this in hard language (specifically IEEE 81 or FOP procedures), but most specifications call for fall-of-potential testing to only be performed after 48 hrs following any generous rainfall to allow the ground to dry.
