Jeff,
The point I am making is that Stephen Frink's sinus should be drained, assuming that he was treated with the correct antibiotic for an adequate amount and duration of treatment. This is irregardless of what organism is present as long as it is sensitive to the medication that was prescribed.
Since we do not know what is growing in Mr Frink's sinus, I don't believe we can comment on the etiology of his infection.
Regarding if contaminated water can cause a sinusitis, I would say yes it is possible. But you know that in general the vast majority of sinus infections are secondary to normal nasal flora like strep and H flu and fungal infections are associated with allergic sinusitis.

Elmer,
I'm not disagreeing with you about the standard treatment for sinus infections and whether Steve's sinus should be drained or not, but this thread is about diving in contaminated water and whether it is related in this case by implication to health hazards such as Steve's sinus infection.
To quote Steve "The issue I'm trying to research is one of ultra-poor water quality that might ultimately impact health ... ears, sinuses, gastrointestinal, etc. Let me rephrase then. Has anyone had health issues that they might think are directly attributable to poor water quality in some of the remote regions of the world where we choose to dive?"
I would submit that the only way to make a connection between contaminated water and infections is to connect the organisms in the contaminated water and the suspected infections. In this case,to make a connection between Steve's sinus infection and contaminated water, one would have to culture some atypical organism possibly found in contaminated water, and not one of the normal flora implicated in sinus infections. Simple example of Koch's postulates in practice.
And as you say we do not know what is growing in Steve's sinus, so my comment is that if we want to know, and if we want to see if it is possibly related to contaminated water, culture it!
