Hmmm, interestingly, I attended a talk about drinking water this week hosted by Dr. Xuan, an MD with years of clinical and research experience, with recent research into healthy lifestyles which led him to research the water situation here in Shanghai. A few notes about what he said about the water...
China has been trying to attain a standard for tap water for years but so far, because of the limits with the older infrastructure, no drinkable water standard has been attained yet. Current water in Shanghai, for example is very "hard' in that there are many minerals, particulates and heavy metals that have not been filtered in the processing at the water treatment plants. What DOES come out of the pipes is disinfected water with chlorine content and a few other contaminants. "Ironically", he stated, "there is nothing that can be boiled out of the water ther than Chlorine these days."
He continued to talk about what he considers "healthy" water. 1) Non toxic and no toxins; 2) Mildly Basic 7.2-7.4pH, which incidentally is the blood pH of newborns, 3) contains necessary minerals (not like many DI and distilled water which are left devoid of any minerals)
What I learned from the talk is that while drinking "pure water' without minerals is not necessarily bad for you, it does tend to leech minerals away from what it comes in contact with as osmosis kicks in, though it should NOT take any thing away from cells already utlizing these minerals. Along the same lines, Reverse Osmosis is also the only way to truly filter out heavy metals to a suitable level for drinking (96% heavymetal free for drinking / 99% free for medicinal use per US FDA standards) Given this, its my goal to find a proper filter that utilised Reverse Osmosis AND can still provide a mildly basic (pH level 7.2-7.4) water with some essential minerals.
As for rinsing and showering, he mentioned that technically, we are showering and rinsing with chorinated water (chlorine being the main active disinfecting ingredient used in public and private water systems ) Heating it up in a hot shower actually make it easier to absorb... so we are actually absorbing much mroe Chlorine than is healthy with all those hot showers. Sorry to make things seem worse... Sigh.
Reg- you mentioned beer...so did the dear Doctor. He mentioned that the best beers and alcohols, come for areas with the best source for clean water. Fresh water is clear, and soft, with a minimum of minerals and the water molecules tend to be clustered in smaller bunches. this water is a better solvent and blends better to make better beer and drinks...as well as a better cleaning solution. Guess a good beer will clean you right out!
Anyhow, i am going to look inot this more and follow up as i find more info.
