The Myth of Bottled Water By Mrs Vera West

Nowadays everywhere you go, people, especially the young have their bottles of commercial water. It is thought to be healthy. But, is it?

“THE lid has been lifted on what’s actually in our bottled water — and it’s probably not what you think.

While some brands claim to be full of minerals you wouldn’t find in a tap, turns out filling the glass at home is better for you.

And if you’re one of those people avoiding fluoride, well the bad news is it’s in the bottled stuff too.

In fact, one company that’s been put to the test — Nature’s Best — was found to be really not that different to tap water at all.

In the season two premiere of ABC’s War on Waste popular water brands were put to the test, comparing them to Gold Coast water in one of Griffith University’s testing labs.

Australian tap water is subject to stringent testing and regulations to ensure it’s safe to drink but bottled water is classified as a food product and not subject to the same controls which means quality and mineral content can vary depending on the brand.

Testing showed tap water has a relatively high concentration of minerals like calcium and magnesium, more than most of the bottled brands, except Fiji water.

Water scientist Dr Fred Leusch also looked at the pH levels or acidity, with a seven being neutral and the lower the number the more acidic the water.

That’s when it can start to damage tooth enamel.

The tests revealed Pump and Mount Franklin were more acidic and wouldn’t pass stringent tap water tests, with Mount Franklin’s sparkling brand the worst in that category.

“Below four is something that does damage your enamel,” Dr Leusch said.

“We’re in the range of Coke and coffee — we know these are not great for our teeth.

“Tap water should really be marketed as mineral water.”

Tuesday night’s program showed how Nature’s Best might confuse people because it is simply branded as “pure, safe, Australian water” on the label.

The Sydney-based company does just put treated tap water in a bottle, with its owner previously revealing he just sees the business as “selling plastic bottles” because the “water is basically free”.

Dr Leusch said anything that said “safe, pure Australian water” was probably just tap water.

“I find the name ironic — Nature’s Best, pure, safe Australian — it’s an acknowledgment that tap water’s safe,” he said.

“In the end, I reckon when you’re buying this, most of the cost is the plastic container. What’s inside is just worth 0.1 of a cent.”

Even bottled water had fluoride in it, with the Nature’s Best brand having slightly more than the tap water. Picture: ABC Source: SuppliedWar on Waste’s Craig Reucassel at the Griffith University lab with Dr Fred Leusch. Picture: ABC Source: Supplied

Gold Coast tap water had a level of fluoride that was expected, but all bottles contained some amount of it, and Nature’s Best had more.

“It’s a natural element, it’s found in some of our groundwaters as well,” Dr Leusch said.

“It’s a chemical found in rocks and so if that groundwater has been in contact with fluoride containing rocks, it will have naturally higher concentrations of fluoride.”

Dr Leusch said it was easy for people to get confused with all the types on the market and the “gimmicks” being used.

“All our water is eventually from the same place, it’s a closed cycle,” he said.

“The water that fills our rivers is actually sometimes fed from the ground, sometimes fed from rainwater — it’s all the same water in the end.

“Because they’re regulated as food the words can have a very specific meaning — spring water must really mean it’s sourced from groundwater. Pure water is more generic than that and it can actually be tap water that has been filtered and bottled into this.”

A statement from Coca-Cola Amatil and Coca-Cola South Pacifics said all bottled water in Australia was required to pass stringent testing and regulations to ensure its quality and safety.

“Bottled water is tested both at the source and in the finished product, unlike tap water which is only tested at the plant,” the statement said.

“Concerns are sometimes raised regarding the pH of drinking water.

“Bottled springwater pH generally reflects the pH of the spring from which it is drawn. “Tapwater pH is maintained at close to 7.0 for purposes including the optimum efficacy of chlorination.”

The statement said many common foods and drinks had a standard pH higher or lower than bottled water.

“Pump and Mount Franklin are pure spring waters sourced from a range of local sources in Australia,” it said.

“The pH levels and mineral content of these spring waters are naturally occurring and determined by the water source from which it is drawn.

“The water is packaged in its natural state, with no adjustments made for pH or minerals during the bottling process.

“Pump water and Mount Franklin comply with the parameters set out by Australasian Bottled Water Institute’s (ABWI) Model Code, which stipulates a pH range of 3.5 – 8.5.”
