How good is bottled water?

Lately I've seen governments making a lot of fun about trying to get people to avoid bottled water in favour of something else. I suppose it's probably better than drinking sugar-water, but I wonder how many people really think about what they're getting given that many seem totally opposed to drinking (filtered) tap water.

Admittedly the following is from Germany, but I wouldn't expect to see much different results out here:

A research project in conjunction with the German Environment Ministry showed that some were as contaminated as water from sewage works for the estrogen-like substances.

Martin Wagner, who worked on the study, said in a statement, “When we started the work we did not expect to find such a massive estrogen contamination in a foodstuff which is so strictly controlled.”

The scientists examined 20 different brands of mineral waters, 12 of which displayed heightened hormone content.

In all the discussions of gender issues today, I wonder how much attention people really pay to environmental factors. Leonard Sax, for example, author of the book Boys Adrift: The Five Factors Driving the Growing Epidemic of Unmotivated Boys and Underachieving Young Men has use of plastics as one of the primary causes that he thinks is making the current/future generation of men less manly.
