I think it funny how this hobby is so uninformed about the physiology of the animals they keep. Unless a snake (we don't keep aquatic snakes in this hobby) somehow soaks so long in chlorinated water it might enter their blood stream by say their cloaca (not likely people, don't get crazy ideas!), it is impossible for a snake to have tissue damage from chlorine treated water because that is filtered out before hitting the bloodstream.
You can safely give your snake chlorine or chloramine treated water without harm because unlike fish and amphibians they lack membranes (skin or gill) that directly absorbs water to the bloodstream. That being said, there is no harm in removing it from the water using treatment agents like reptisafe. If you don't trust zoomed, use another product if you are concerned. There are dozens of products out there that do the same thing. Or look up a water report for your municipality online as they are all legally required to post them. Find out what is in your water and be informed.
For me I have used reptisafe or the equivalent longer than some of you have been alive and will continue to use it as long as I have reptiles, fish, or keep delicate plants
