Bottled Water – Damaging The Environment

7th August, 2009 - Posted by health news - No Comments

For the past decade or so, the level of bottled water sales has been steadily rising by 7 – 8% per annum. The level of consumption globally is estimated to have more than doubled between 1997 and 2005.

Around about 200 billion bottles of water are consumed worldwide annually. The US market is the biggest by far, making up 25% of global sales.

However, there has been a backlash against the use of bottled water. One of the main causes for concern is the environmental impact of bottled water. The actual bottles are usually made from Polyethylene terephthalate (PET), which is a recyclable material – but the actual level of recycling is believed to be less than 25%.

The energy required for production, transportation and disposal of the bottles is also a source for concern among environmentalists. When compared with tap water, bottled water produces carbon emissions which are 5,000 times greater per litre.

In spite of the very effective marketing of the bottled water suppliers, there seems to be little evidence that bottled water is, in developed countries at least, more beneficial for your health than plain old tap water. Some bottled waters have been found to contain estrogenic chemicals and even uranium. Most bottled waters have some level of salt present – which is bad for your blood pressure.

In terms of taste there is little firm evidence that bottled water is superior to tap water. In a blind tasting in the UK, London tap water finished in third place from a selection of 24 different water varieties. In the USA, a 2007 episode of Penn and Teller (which may have been more entertaining than scientific – but is still worth mentioning) demonstrated that diners could not distinguish between bottled water and water drawn from a garden hose.

In terms of cost to the consumer the precise ratio will vary according to the brand of water under consideration, but generally speaking bottled water is priced at several hundred times more per litre than tap water.

So, in terms of environmental impact, health, taste and cost, bottled water really doesn’t have a lot going for it. If you really can’t bear the taste of the water that comes out of your tap then you might be well advised to consider some type of home filtration system. The cost will be higher than tap water, but much lower than bottled water. If you opt for a solution such as the Brita water filter jug then you can be certain that it’s better for the environment as all parts of the filters are recyclable.

Of course, home filtration systems are great for when you’re at home – but if you like to carry water with you when you’re out and about then you could use and reuse a bottle which you fill at home, or the office, before you leave. Again, Brita water are a good example having partnered with international designer Orla Kelly to produce the Wottle – which claims to be the world’s first designer reusable bottle and is manufactured from 100% recycled material. Or you could just try a bit of recycling of your own and use an old soda bottle.
