RE: Swimmers should take E. coli warnings seriously

[Molina.Marirosa@epamail.epa.gov]

It almost sounds to me like it could be six of one or half a dozen of
the other.  It is obvious that both the storm drains have a strong
influence on the counts as well as resuspension from the swash zone.
Under a rain event, presumably both sources will increase the numbers,
one from flushing and the other one from resuspension.  Has anybody
compare the numbers of one vs. the other in the same study, and of
course, establish the relationship with the environmental parameters
(rain events, turbidity, TSS, etc).  If not, maybe a suggested study is
in place, the output probably needs to be considered as additions to the
predictive modeling efforts going around.  Maybe from the stand point of
more process based modeling?
