mayor not happy that the public was notified of high
turbidity levels; calls for investigation (Arizona
Republic, January 28); Manager
of Phoenix water department removed from his job
(Arizona Republic, January 29);
is what the Mayor should have read before reacting!
(Arizona Republic, January 31)
Obviously, this was a tough call for Mike
Gritzuk last week during the high-pressure situation
where a treatment plant was putting out high turbidity
water and there was no flexibility to shut the plant
down. We do not know all of the facts of this
situation, but if a water manager decides public health
may be at risk and a boil water advisory is necessary,
he should be given a lot of latitude by his bosses.
We hope that other water managers will not be intimidated
by this action and, during crisis events, will have
the courage to make the hard choices where public
health protection is of paramount importance.

Cryptosporidiosis Decline after Membrane Filtration
of Public Water Supplies, England, 1996-2002
(Emerging Infectious Diseases, February 2005)
Talk about your confounding factors! Wow!
This effort to epidemiologically evaluate the benefits
of putting in membrane filtration was dramatically
impacted by a Foot-and-Mouth-Disease outbreak shortly
after the new treatment was put on line. How
so? Crypto exposure was decreased both by the
culling of herds and by limiting public access to
the cows. But, the researchers were able to
tease out the answer: Membranes be good! Great
school well has sporadic coliform problems; continuous
chlorination planned (Daily Oakland
Press, January 29)
Hampshire town is boiling water because of positive
E. coli results (Littleton
Courier, January 26)
Examples of the adage "don't believe everything
you read in a newspaper." For instance:
"Last January, the EPA suggested that Welch
turn off the chlorinators for the town’s water supply.
They informed him of the health risks associated with
chlorine, and the potential environmental impacts
from chlorinated water entering surrounding lands.
At the time, Lisbon was one of the few towns in New
Hampshire to draw its water from a well and still
employ chlorination. Concerned about the risks
to the health of Lisbon residents, Welch shut down
the chlorinators." and "...it
is relatively common to have water samples test positive
for different types of fecal coliform."
Not in finished drinking water, as evidenced by
the many, many thousands of samples taken every year
by US drinking water suppliers that have zero coliform
of any kind.
Profile Analysis: An Analytical Method that Every
Water Utility and Lab Should Have Available
of drinking water is crucial to the success of anyone
serving drinking water customers. Dr.
McGuire, founder of McGuire Environmental Consultants,
Inc. (MEC), led the way in adapting the Flavor
Profile Analysis (FPA) method to the analysis
of drinking water in 1981, and since that time it
has become the "gold standard" for assessing
the taste and odor characteristics of drinking water.
McGuire Environmental Consultants, Inc. is
a specialty firm whose goal is to help utilities
produce safe drinking water. In addition to Flavor
Profile Analysis, we provide a wide range of
services to the municipal and private water utility
market, especially in the areas of water quality
and water treatment.
