It will however outgas from the liquid  (I'm not sure this is the
technically correct term, but you should get the idea.)  For
example the chlorine in most municipal systems can kill fish
in your fish tank so it is generally treated first.  One way is
to add a neutralizer from the pet store, the other is to simply
let the water sit out for several days to a week.

I've seen bees use treated pool water when other sources dry up to
no ill effect, and I'm sure others have as well.  I have no idea what
percentage of chlorine typically is used in a pool.  I assume it would
be a relatively safe level for the bees, but I don't know how it relates
to the concentration in store bought bleach.
