My county uses chloramines now, but even before, I wouldn't drink the water from the tap, to say nothing of giving it to my animals. I have a triple osmosis system under my sink, and all my animals, dog's, cats, and reptiles drink it. When our water was tested by a guy that was selling those total home water systems, my osmosis system made the water almost completely pure. The unfiltered water from the tap, had more than 800 ppm of all kinds of sediments. He wasn't even certain what some of them were since his system didn't remove all of it. He said that in many places when the ppm get above 400 they tell people not to drink it.
