Not suitable as drink? inedible for food, how about an adjective for drinks

[moonlike]

Hi
Could you say what we use for drinks that aren't suitable to drink? I'm looking for an adjective like 'inedible' that we use for something that's not suitable as food.

Thanks a lot.

"undrinkable"

I agree with bhai.

Additionally, we do have the word potable, meaning 'fit to drink', but for some reason which I have never understood, no major dictionaries, and only two minor ones, list its opposite – impotable.

Non-potable.

That's fine, but I rarely see it used.

I see "Non potable" so often in France that it looked absolutely normal when Barb posted. Then I realised I've never seen the English hyphenated version used.

I've seen it used on taps and also not for drinking. I think the problem is that in many English-speaking countries you can drink the tap water, so there isn't a standard phrase.
