Bottled Water Comparisions

Clive emailed me yesterday with some interesting observations he's made on so-called spring water in plastic bottles that now costs more than gasoline per litre.

"Dear Ian,

I have one of your Alphion alkaline water makers, which I think is wonderful.

I have recently analysed a number of the bottled still water brands on sale around Perth and found to my surprise that most of the water is acidic; however when I looked at the bottled water on sale in Brisbane, most of the water was alkaline. I did note also that the components of Woolworths “own brand” was different in both states, suggesting that they source water locally to fill their bottles.

Attached is a view of Perth bottled water – I was surprised at how acidic one of the popular brands is (Peats Ridge) – I have decided to use it as top up water for my car battery instead of using it as water to drink while driving my car!"

If you'd like a copy of Clive's excellent report, click here to download an Excel file.

And while I'm on the subject, here's a graphic that tells us why people drink bottled water.

This is very useful so thanks to Clive. I use the alkabalance drops in bottled and/or tapwater and this has raised a question about adding the drops to water that is already alkaline. Would it make the water too alkaline for consumption then? Sue

Oh.. and looks like it turns out to be a little more to Evian.. there really is some quality and it's not just a well marketed designer water that has had us all stooged.

Hi, Sue, AlkaBalance only adds sodium and potassium bicarbonate. generally, already-alkaline municipal water is higher in calcium than these minerals so you'll get a more balanced pH.

Re Evian; I think the time is near when the transport of a litre of water in a plastic bottle for thousands of kilometres will become a climate change NONo! We need to be looking for alternatives now. (The plastic bottles used in the US in one year would fuel a million cars in the same period.)

Thanks Ian. I won't think I'm ODing on alkaline if such a thing is possible :o)

Re Evian - I was strictly speaking about the contents not the container.. all plastics are a problem but it's a problem is much more widespread than just Evian and bottled water, it's soft drinks, health drinks (?) and a myriad of other plastics that we should be seeking to reduce. I think, and I preface this with my eternally optimistic view, that the world is waking up and change is heralded.

I use a my own water container anyway and don't buy water unless it's imposed on me situationally and usually then you're paying triple the price for it.
