“Recent tests of water quality have found significant levels of antimony, a toxic chemical element, in polyethylene terephthalate (PET) bottles” says Professor William Shotyk, director of the Institute of Environmental Geochemistry at the University of Heidelberg, said The study, involving 132 brands, found increasing levels in bottled water that had been stored for six months at room temperature. Some results reached close to 2,000 parts per trillion, which is the Japanese limit for drinking water.
Mr. Shotyk said the findings raise questions about the purity of bottled water, but the industry is growing fast with limited public scrutiny.
