I don't know of chloramine and bees, but chloramine and chlorine are also
toxic to aquarium fish.
 
There are various "chlorine removers" available for fish at pet supply
shops to remove chlorine/chloramine from tap water.  The solution may be as
simple as using this for the bees, unless it is also toxic to them.
I believe the active ingredient in chlorine removers is sodium thiosulfate.
