a well written post, but for for others reading, and as a student of toxicology, risk assessment and evaluation I gotta ask, are you suggesting tap water is not safe to drink?
i use RO water for my coffee, RO/DI for my aquarium and drink tap water...

So before you freaking out about how rats urinated more from a water drinking study and how important it is to obtain that 0.0005% daily intake of calcium from water consider the following.
- Tens of thousands of chemicals are used, only a few dozen are actually tested and regulated by water treatment.
- Both government and independent scientists have linked even low levels of hundreds of legal contaminants in tap water to cancer, reproductive difficulties, and other diseases. There are more than 2100 known drinking water contaminants that may be present in tap water, including several known poisons.
- Drinking water regulations are out of date, many treatment plants were built decades ago to remove only harmful bacteria and nothing else.
- Pharmaceuticals have been found in the tap water, water treatment plants are not currently required to test for pharmaceuticals.
- Studies in some areas of Canada have shown high lead content in tap water, lead can increase the risk of learning disorders in small children.
- Every year, 18 billion pounds of new pollutants and chemicals are released into the atmosphere, soil, and groundwater.
- The only way to ensure pure, contaminant-free drinking water is through the use of a point-of-use filtration system such as an RO unit.
If you're worried about mineral content, take a multivitamin. Personally if you have RO water in your house I think you'd be a fool not to drink it. DI may be a separate issue but not something I worry about but those who do can simply tap in before the DI filter to access RO water for drinking purposes. |
