How sure are we that the gasohol in service station tanks contain no water?

It's pretty sure to contain some water, at least some of the time,
especially in summer and especially in the east. As the tank is drawn
down, air is going to replace what's been pumped out. That air is
going to contain some water, which will be absorbed in time by the
alcohol.


Is it possible that all tanks containing gasohol contain at least some water
dissolved?

See above.


Is it a certainty that the alcohol added to gasoline contains no dissolved
water?

Well, the alky presumably was shipped in full tanks / barrels /
whatever, so we can hope it's undiluted.
