Dear Potential Speaker or Participant,
Please contact me by email at Berger.philip@epa.gov or telephone (202)
564-5255 if you wish to present or attend.
The 2008 EPA GW Epi Symposium was oversubscribed and we had to add a
third day of presentations. This year, the key speaker will present the
results of the Sonoma Water Evaluation Trial (SWET), published in the
American Journal of Public Health. Sonoma County Water Agency is
regulated as both a ground water and as a ground water under the direct
influence of surface water (GWUDI). Another key speaker will present the
results of the US Geological Survey work at the Miami Dade Northwest
Well-Field to establish the potential Cryptosporidium hazard using
tracers.
Conference registration is FREE. At this time, I have NO travel dollars
available to assist speakers or participants.

The Sonoma Water Evaluation

Trial: A Randomized
Trial to Reduce
Older Adults
PhD, MPH, Joan F. Hilton, ScD, Catherine
F. Arnold, MPH, Sona Saha, MPH, Timothy
Scott, PhD, and Joseph N.S. Eisenberg,
Objectives. We estimated the relative rate of highly credible
gastrointestinal
illness (HCGI) per year associated with active versus sham household
water
filtration devices among older adults in a community receiving tap water
meeting current US standards.
Methods. We conducted a randomized, triple-blinded, crossover trial in
714
households (988 individuals), which used active and sham water
filtration
devices for 6 months each. We estimated the annual incidence rate ratio
of
HCGI episodes and the longitudinal prevalence ratio of HCGI days at
population
and individual levels with a generalized estimating equation (GEE) and
generalized
linear mixed models (GLMMs), respectively, adjusted for covariates
associated with outcome.
Results. The incidence rate ratios (active versus sham) were 0.88 (95%
confidence interval [CI] = 0.77, 1.00) and 0.85 (95% CI = 0.76, 0.94)
HCGI episodes
per year estimated by GEE and GLMM models, respectively. The
corresponding
longitudinal prevalence ratios were 0.88 (95% CI = 0.74, 1.05) and 0.84
(95%
CI = 0.78, 0.90) HCGI days per person per year.
Conclusions. We observed reductions in population- and individual-level
measures of HCGI associated with use of the active filtration device.
These
findings suggest the need for further research on the impact of drinking
water on
the health of sensitive subpopulations. (Am J Public Health.

Hello Philip,
I just had a snack with the other Berger (Paul) and your name came up.
There's an opening for a speaker on 27 Jan 2010 at GSW. We'd love to
hear about this or other water-related topics.
Yours,
