Bottled water and bacteria.

Buyers of bottled water, mistakenly believing it “greener” and safer than the tap variety, have had a terrible shock recently.

Journalists reporting the volte-face have also been pointing out that the product is nothing like as pristine as its purveyors claim. It contains large numbers of bacteria.
