William,
Boiling will kill most, but not all micro-organisms.
Steam at 15psi for 15 minutes will kill all known micro-organisms including aids.
Since few of us have autoclaves on our boats you will have to resort to a disinfectant to kill what the boiling won't kill. Bleach or iodine will work.
To be perfectly honest with you I can't remember how much iodine per gallon, perhaps another list member, might know.
After the disinfectant is added to the water, shake and wait at least 15 minutes before using.
With bleach we use 1 or 2 milliliters per gallon after filtering for people or for birds.
On our city water we use a 5 stage R.O filter setup and add bleach afterward.
As an interesting sidenote, we were having a 100% mortality rate for all macaw prehatch chicks before switching to this system.
Note, all filters must be disinfected on a regular basis.

Subject: [worldcruising] Water Purification
Hey group,
I was buying bottled water for my drinking water. Then I
decided to just boil the water from my water tanks
that came from the dock water and let it cool
overnight for my drinking water. I don't have any
reason to doubt the quality of the dock/tap water
at the marina I'm currently docked (SF bay area). Maybe
me just being paranoid and for future cruising
reference as well.
Questions:
1- Is boiling water the most simple and cheapest way
to purify drinking water?
2- Do any of those at the faucet water filters purify
the water to the same level or better than boiling
or bottled water (depending on how pure bottled water
is in the first place!)? I was thinking of one of those
PUR at the faucet with on/off switch for filtered/unfiltered.
Are there other good at the tap water purifiers? Anything
important I should look for in a at the tap water filter?
Microns, what it filters, etc.?
3- What ways do any other list members on the more paranoid
side of the fence like me quality control their drinking water?
Thanks very much... for all your great answers in advance.
William
