I stand corrected.
My information was from the water treatment plant in Denver, and I considered this a valid source without doing any further research.
I still maintain, however, that water from the tap is completely safe for chameleons and that, regardless of the FDA regulations, there are bottled water companies that treat their product in the way I originally described.
Further, although it is true that the FDA does not require that chlorine be added/included in bottled water, it is also true that some bottled water has been chlorinated and had the chemical removed.
