This year (or maybe late last year) I received a letter saying chlorine was no longer going to be used in our water supply and that Chloramine would replace it. They cited that it had no aftertaste. I don't know about you folks, but I like to know what I'm consuming and if there's likely to be any side effects. If anyone has noticed new symptoms since the switch-over it would be useful to share. Some folks in the USA have noticed skin rashes, difficulty breathing etc. The first link is very important: https://www.ewswater.com/chloramine-what-is-it-and-how-do-you-remove-it/ http://www.chloramine.org/chloraminefacts.htm http://articles.mercola.com/sites/articles/archive/2012/11/27/drinking-water-with-chloramine.aspx http://www.fbas.co.uk/Cmines.html
