So long as you can stand the smell, unscented bleach is no more hazardous to you than chlorinated tap water if you didn't go overboard. If you just can't swallow with the stink, let it air out over night or add something with some vitamin C or some make tea/coffee out of it.

I store my water is OJ cartons in the freezer, or three jerry cans, one of which gets refilled every other week (6 weeks max storage time) so I'm not so worried about expiration dates.
