Water is Goulburn is pretty good. I personally have never had a problem with Goulburn water. Though my mother in law for example doesn't drink water out of the tap and uses only filtered water. I have heard some people say that the water makes them very sick and it's quite often that people will buy bottled water. Let's just say, all water bowls for animals, should be cleaned every one to two days to avoid slime and brown bowls..
