I read yesterday that 200,000 liters of sodium chloride have been
distributed in Indonesia; this is enough to purify water for one
million persons, the article said. I am totally unfamiliar with
sodium chloride, but this is what is on the scene.
I still want to get a supply of those resublimated iodine crystals
mentioned below, but I have not yet stumbled on a source of them.

Hi folks,
I clipped this from this very list some unknown time ago - very
fascinating in the light of the Tsunami tragedy.

From(Principles of Pharmacy--Arny-Fischeles). From Remington's
Pharmaceutical Sciences 17th edition:
Iodine is one of the three best all-around antiseptics. It is active
against
bacteria, fungi, yeasts, protozoa, and viruses. Iodine may be used to
"purify" drinking water. 5 to 10 drops of 2% iodine tincture to a
quart of
water left for 1 hr. is both amebacidal and bactericidal. Some
communities
use iodine in lieu of chlorine for water purification because organic
matter
has little effect to antagonize iodine, as it does chlorine, and
carcinogenic compounds are not generated.
Related topic: I read in a great Reader's Digest hardcover book on a
"back to nature" theme that the best, simplest water purification kit
for hikers and survivalists is a small, clear screw-top jar with five
grams of resublimated iodine crystals. I have never heard the term
"resublimated" and hope our pharmacist Mr. R. Harris can enlighten us.
Bottom line: one bottle of these crystals can be used ONE THOUSAND
TIMES. Fill up the jar with any old water and shake it. Three tsps.
of shaken water can purify a quart in 20 minutes. Remarkable, I
think. Seems to be a modest supply of these crystals would last the
average family for decades. They are available only from a pharmacy
I read.

What a good idea to use our contacts to get this AND CS information to
some of the aid agency people? Anyone?
BTW: SUBLIMATED: Having passed from the solid to the gaseous state
(or vice versa) without becoming liquid. RE-sublimated?
Cheers,
Himagain
