Thanks for the info Emil. I remember now reading of the silver coin in water from another thread. Somehow I think it sounds kind of weird though. We use untreated well water and I could stand a bit of chlorine in an emergency. Usually we have some water supply interruption during Winter. It is reassuring to have a palatable water supply stored. Better safe than sorry. Brian
