All of those folks you see toting water bottles must know something about the value of drinking water. If water is good for you then, ultra pure water must be even better--you would think. But is this in fact the case?
As a youngster I would work a full day in the field and have a cup of tea around 10:30 and another at 12. That was it! No thought of dehydration or anything like that. I'm still here so it can't have been all that bad for me.
These days, I notice ladies walking around the block with a flask at their hip. Methinks they go too far.
Later in life that it was suggested to me that I would live longer if I drank more water, and so started to drink more of it. What I am finding is that I definitely feel more alert after a drink of water, so I'll keep doing it.
Pure water sounds good and ultra pure water would appear to be even better--but I think not.
Back on the dairy farm, my father would say that fresh milk got its flavour from the bugs that were in it. After pasteurization (heating for a time), microorganisms in the milk are destroyed, slightly altering the taste. So it is with water.
I'm not suggesting that microorgansms shouldn't be removed from water--they should be. What I am suggesting is that to obtain good tasting, beneficial water, selective removal of substances is the answer.
The problems with pure water are not so much that there is anything left in the water that may harm you, but that beneficial minerals are taken out. Calcium and magnesium are two such minerals that would be removed and they are vital for good health. Also, the pleasant taste would no longer present.
Of course, with a process which did this, while there would be nothing left in the water that could harm you, it wouldn't be as good for you as a process which left the beneficial substances there.
Distillation is one method used to produce ultra pure water. Another is reverse osmosis.
Distilling water involves heating water and cooling the steam to produce water. Reverse osmosis involves forcing water through a semi permeable membrane. Distillation is too costly for home use and reverse osmosis fails to remove many toxins.
Bottled water isn't really a solution either. That industry is unregulated and tests have shown there is little difference between bottled and tap water.
The solution to obtaining pure water that has a pleasant taste; which is good for you and which is cost effective for home use, is to use a system that employes at least 2 fitration methods in its filtering process.
