We have a county council water supply and this has been checked and shown to conform to acceptable standards.
We have seen the report and note that there is arsenic, cadmium and lead in the water amongst others but still withing acceptable limits.
Is this the case in general regarding these minerals/contaminants?
We have looked at reverse osmosis and been told that the water may be so pure that it may attract ions etc from your own body as the water may be unstable due to its purity?
Unfortunately, the urban myth of RO water being so pure that it does odd things within your body, is a nonsense that still does the rounds.
Globally, no authority yet large or small has authenticated any evidence to show that residential RO water filters are able to draw ions from the human body or affect our hyperstasis.
The World Health Organisation after looking at thirty years worth of odd opinions that have emerged from time to time regarding minerals or lack of minerals in water have now settled on an approach that massively recommends RO technology large and small for helping towards the world's future water demands.
The W.H.O. also put out an official statement recently that states that water cannot be reliably looked upon as a source of minerals.
All residential RO systems available cannot provide water at a purity that affects bodily hyperstasis, and the truth is that if water was commercially refined to the ultimate level of purity to 18.3 megaohm D.I. quality for semiconductor, pharmaceutical and nuclear uses, it still would be perfectly fine to drink for most people, as the pH would still be an exact 7.0 balance.
Residential RO systems do not raise water purity to commercial levels however, and generally work on excess minerals and salts not in the 99.999999 removal level, but actually in the 85% to 95% removal level.
It is the nasty stuff like heavy metals that RO are very good in removing in the 99.9% range, even on a domestic level.
For four or more decades, residential RO systems have had a perfect world wide medical track record for exceptional quality water, and because RO is so proven it has been used for decades as the only water treatment technology for re-processing water on all long term space station missions, and long term naval submarine missions for all crew.
GE and Siemens are two of the worlds largest technology firms and both have been making and selling top level residential and commercial RO systems for decades.
I can absolutely qualify that remarks made by certain microbiologists based in Dublin that have appeared in the past on TV to give opinions about RO water quality from residential devices as being so misleading that they are both unable to re-substantiate past opinions and have now withdrawn from making any repeat of mistakes of trying to describe the performance of RO systems in general, such was their past embarrassment of their comments.
The thing with RO systems, for the new age hippy types, is that you can pop on a mineral cartridge after the RO if there are spiritual doubts about the water energy, or contaminant reduction to levels where minerals come down to the levels of Volvic water.
Volvic bottled water is the example of a highly successful water sold globally with a refreshing sort of taste, that actually has little or no minerals at all. It is so low on minerals it is actually classed as a spring water and not a mineral water, but is generally mistaken by 90% ? of the population as a mineral water.
Most RO systems after an average span of operation leave as many minerals in water (well as much as the 9.9 mg/L calcium in Volvic) as many spring bottled waters and more so above the new chunk of the RO bottled waters from the world's food giants like Kraft and Coke that are selling Zero mineral level bottled waters (commercial process RO) that now have over 30% of world market share.
