Honestly I do not know, that is just something I read in specialized forum very long time ago. But some points: - EU Shengen rules are pretty strictly enforced. EU even regulates "curvature of bananas". I can not imagine situation where Germany could not sell bottled water on Czech market. - All formulation are talking about human health; "essential quality and health parameters" or "if human life is endangered". I do not think this applies to german bottled water. Czech springs (and bottled water) are pretty high quality, and our limits were very strict even compared to international standards. - I mentioned it as a curiosity. Because communism caused lot of pollution in here. Back in 2000 it was a huge contrast to cross borders to Germany or Austria. It is surprising that we had stricter rules on water.
