I'm not sure where that info comes from, but from the manufacturer, see here:http://www.bluescopesteel.com.au/litera ... ater-tanks
""The polymer film is not resistant to ultraviolet light (UV) and as such should not be exposed to sunlight.
The polymer film is a 200µm thick, food grade material manufactured in accordance with Australian
Standard AS2070-1999, Plastic Materials for Food Contact Use"
I would think that there is no UV stabiliser in it, as it is not supposed to be exposed to UV radiation/sunlight. As for BPA, I don't know- they don't mention it, but neither do most plastic container manufacturers mention it, only its absence!
I've been drinking water from a galvanised tank here for about 20 years (and occasionally from other gal tanks elsewhere for many years prior to that), and also from an aquaplate tank here for about 10 years, and seem to be surviving so far
I also store excess in poly tanks, and have been drinking water from them as well for the past 10 years or so. Stainless steel tanks would be nice, except for the $$!
