Since it has no calories, it's not "food" by even a very loose definition.
As someone who lives in a neighborhood where most tapwater is still delivered by lead service lines, I'm sympathetic to the argument that it provides hydration. I'd prefer that my tax dollars went to solving that problem more directly, however.

I think it could be argued either way. There's plenty of non-food necessities (toilet paper, feminine hygiene products, etc.) that aren't covered by SNAP.
