Among the reasons for the persistence of chlorine as a water purifying
agent,
is a whole list of regulations that specify "residual kill time" for municipal
water systems. In short, while chlorine eventually becomes oxidized and
ineffective, it remains effective for quite a lot longer than ozone. Any water
system manager who wants to avoid litigation will specify chlorine as the
oxidizing agent for this reason. (It seems our friends in Europe are a bit more
understanding about risk, and don't seek to litigate as readily as we Americans
do.)
Further, I've seen some research somewhere (this was YEARS ago already)
suggesting that ANY oxidation agent increases long term cancer risks. If this
is
so, the question becomes: Do you want typhus and cholera now, or are you willing
to risk cancer in forty years?
Personally, I think point of use filtration should be mandatory for every
household--especially in developing countries, where many people do not have
access to clean water.
I'll get off my soap box now. . .
