"But the real public relations disaster came later. After the recall, it came to light that the water was simply treated and purified tap water from the factory, a practice which many point out is common in the bottled water industry."
Germany is very strict about it´s classification of waters...Since studying over here, I´m afraid I know more about the German classifications than about those in my own country

anyway here there are basically 5 categories:
1.Natural Mineral Water (Natürliches Mineralwasser)
2.Natural Healing Water (Natürliches Heilwasser)
3.Spring Water (Quellwasser)
4.Table Water (Tafelwasser)
5.Drinking Water (Trinkwasser)
Numbers 1 and 2 are the most restrictive. They require original purity, origination from an underground and contaminant free water source, minimum mineral and trace element levels (for #1), proof of healing ability (for #2), official recognition (for #1) and official approval (for #2), bottling at the source.
Number 3 only requires the underground source, minimum mineral/trace element levels, and bottling at the source.
Number 4 doesn´t require any of the above!
Number 5 applies to all water (original
and treated) that is fit for consumption, cooking (or preparation thereof), or for household cleansing and sanitation. This water category applies regardless of the source of the water or it´s form.
There are a lot more intimate details. To me, saying that a water has been "treated and purified" is not necessarily a bad thing, however I think that the German system allows us to be more choosy in picking which bottled water to drink from. I don´t know how it is in England, but here bottled water is a very loose classification. The water here is safe for sure -whichever category one drinks from, but we have to assume that the quality control programs are effective!
