With ozone there are sometimes disinfection byproducts. In drinking water issues it usually smells and tastes a little bit like bananas. Certainly, it depends on the source water quality that's coming in. That's a fairly rare case. In the case of Windsor, they don't have any disinfection byproducts in that particular case. I wasn't actually aware of this information, so I find it quite interesting.
