[Greenbuilding] [BULK] Re: Acidic Water

[wmdorsett at sbcglobal.net]

Water supplies in cities are often referred to as depositing supplies,
indicating that the water is basic enough to deposit a slight layer of
calcium carbonate or other similar basic deposit in the waterlines. In older
towns, this can isolate the water from lead pipes in older segments of both
the cities' side and the residents' side of the plumbing. So the lining is
protective. If the ph of the water is lower, then the water not only doesn't
deposit a slight lime layer but corrodes the pipes as you've mentioned with
the copper pipes. Too much of any metal is not healthy, ie the silver tint
that becomes perminent with too much silver, and I think copper can impart
the blue color in the same way.

Exactly what do you think is obvious about the desirability to avoid acid
water.   Except in extremes, I don't see the problem.   Enlighten me.
