Water in CH too hard?

Dear all,

over lunch I heard from a colleague that he and his family only drink mineral water instead of pipe water here in Switzerland as the content of hardness could be very high and he has two friends who suffer kidney problems because of that...apparently it depends on the source of water and as usual it varies also here in CH.

I would like to know if it is true as I never heard of the concern before and I drink pipe water directly here in CH all the time...

Re: Water in CH too hard?

There are always worriers aren't there? Ask your friend to read the label for the mineral contents of his bottled water. Ask him for the chemical analysis of his local water supply. Then see which one has the most minerals.

Re: Water in CH too hard?

Yes, he said (again, I did not verify) that CH has the highest rate of kidney stone cases of the world...and he does check the values published by canton Vaud which is higher than his mineral water.

I tried to find online but still can't find a conclusive study which says hard water is bad...

Re: Water in CH too hard?

I drink mostly tap water here in CH. But I've wondered before if too much calcium (from the water) is bad. I know that there is a condition where too much calcium can actually weaken your bones:

"Your body needs a balance of calcium and phosphorous to rebuild your bones. If this balance is disrupted, including by intake of calcium that exceed intakes phosphorous, your body is unable to break down and reabsorb calcium to form new bone, and your bones become brittle and weak"(http://www.livestrong.com/article/49...cium-on-bones/).

I also found an article where:

"One study found that women who consumed 1,400 milligrams or more of calcium a day had more than double the risk of death from heart disease."

So perhaps it's not wise to take both calcium supplements AND to drink a lot of the tap water here, but I don't know...

Tell your friend to stop complaining and buy a BRITA filter.

Re: Water in CH too hard?

Just add a teaspoon of vinegar to every cup or glass of water you drink.

Is it OK if I chase each glass of water with a packet of salt&vinegar crisps?

Re: Water in CH too hard?

The water is indeed hard in many areas. Our area is especially hard. When making beer, the pH of the raw water has to be adjusted to make things work.

As for health concerns...when in doubt drink red wine.

Is there a specific area/region where you would like more information?

Re: Water in CH too hard?

There have been 100s of official scientific studies comparing tap water and bottled water in Switzerland recently. All have come to the conclusion that drinking bottled water here is a nonsense in more ways than one, including ecologically. Actually most bottled waters contain a lot more salt and minerals.

I typed "hard water kidney stones" into google (I'm so smart!) and the first hit was:

Re: Water in CH too hard?

I second what Sbrinz said. Also found this online: http://www.kidneystoners.org/information/myths/

The last one in the list references hard water.

Well, the hardness here is zero, it depends where you live if you have hard water or not, it's not the same even 30km away.

I don't see those poor African kids complaining about the hardness of their water after traipsing across the dirt 50km to fetch it, do you? Eh? EH? *shakes head*

Re: Water in CH too hard?

Our water was also so hard, it seemed to be easier to measure the water content of the stone coming out of the tap. The hot water tank was descaled in 2010 and here's a picture of the limescale mountain inside it in 2012. It's a bucketful. The toilets were also 80% blocked with scale formations, which required a full strip-down and mechanical removal of the formations. This scale was a bit discoloured, due to the frequency of passing submarine traffic.

We got a water softner fitted (ion-exchange) and now:
No more limescale mountains in the HW tank (which we have just replaced).
No more limescale in the kettle, iron, coffee machine, steamer, or anything else that heats up water.
Need much less detergent in the dishwasher and washing machine and in general.
No salt required anymore for the dishwasher.
No more limescale ring marks on the surfaces and floors in the bathroom or kitchen, or when cleaning the windows
Skin feels amazing after a shower, even shaving is slightly noticably better
No more deposits in the toilet (limescale, that is)
Nice cups of Yorkshire tea
No longer need to replace the aerators on the taps, or descale the shower heads.

Very happy indeed. There's some bla-bla about increased sodium-ion intake, but I'm really not interested.
It cost 3500SFr from Felix in Gebenstorf; this also included all pipework, new water filter and pressure reducing valve, new drip tray, with a 100CHF photo-discount, plus another 100CHF off as we included their Duck Mascot in the photos.

It's the Eskimo kids I feel sorry for. Look how hard their water is.

1. Swiss water is, at worst, very much softer than can be found in parts of neighbouring countries, including France and the UK.

2. Hard water doesn't cause kidney stones.

3. Where does this myth about Swiss water being hard come from?
