According to a new independent study, "Bottled Water: Understanding a social
phenomenon", commissioned by WWF, bottled water may be no safer, or healthier
than tap water in many countries while selling for up to 1000 times the price. Yet, it is
the fastest growing drinks industry in the world and is estimated to be worth US$22
billion annually. The study reveals that the bottled water market is partly fuelled by
concerns over the safety of municipal water and by the marketing of many brands which
portray them as being drawn from pristine sources and as being healthier than tap water.
However, some
bottled waters only differ from tap water in the fact that they are distributed in bottles
rather than through pipes. In fact there are more standards regulating tap water
in Europe and the US than those applied to the bottled water industry. "Our attitudes
towards tap water are being shaped by the pollution which is choking the rivers and
streams which should be veins of life," argues Richard Holland, Director of WWF's
Living Waters Campaign. "We must clean up and properly protect these waters at
source, and not just at the treatment works, so that we can all rest easy in drinking from
the tap."
The study acknowledges
that while bottled water has the advantage of being generally safer in areas where tap
water may be contaminated, boiling or filtering local water renders it safe at a
much lower cost for people on a low income. However, according to the United
Nations Food and Agriculture Organization (FAO), in terms of nutritional value, bottled
water is no better than tap water. It may contain small amounts of minerals but so does
tap water from many public municipal water supplies. Some consumers prefer bottled water
to tap water for taste reasons. WWF argues that water companies have an important
responsibility to ensure that they consistently produce water that is not only safe but
also pleasant to drink.
The study also finds that
every year 1.5 million tons of plastic are used to bottle water. Toxic chemicals can be
released into the environment during the manufacture and disposal of the bottles.
Furthermore, a quarter of the 89 billion litres of water bottled worldwide annually are
consumed outside their country of origin. Emissions of the green house gas carbon dioxide,
caused by transporting bottled water within and between countries, contribute to the
global problem of climate change. "Bottled water isn't a long term sustainable
solution to securing access to healthy water," said Richard Holland.
