Re: Is it okay to boil water more than once

The exception might be the household that leaves a tea ketle on the
wood range 24/7, adding water as it steams or boils away.  Normally
50% or more of that water would be used daily but if refilled
repeatedly for days without using much or any, you could get
(estimating here) a 10:1 concentration of anything non-volatile and
non-heat labile.  Any potential risk would depend on pre-existing
borderline levels of heavy metals or very stable organics in the water
source.

There's no risk from using "previously boiled" water.
