With more Americans turning to bottled water believing it safer and healthier than tap water, there are growing concerns over how water is marketed, sourced and tested for safety and purity.

在美国，越来越多的人引用瓶装水，并认为瓶装水比自来水更安全、更健康。同时，对瓶装水的销售、来源和安全及纯净程度检测的担忧也越来越多。

Beverage Marketing Corporation的统计显示，在过去的十年里，美国人对瓶装水的消费量翻了一番。

"Consumers spend 1,900 times more for bottled water than for tap water, yet they rarely know basic information about exactly what's in their water bottle," said Jane Houlihan, an Environmental Working Group researcher.

“消费者饮用的瓶装水量是自来水的1900倍，但是他们中很少有人知道这些瓶子里的水到底是什么。”一位环境工作研究者珍·胡莉说。
