“that Tamiflu is being excreted into rivers”
I don’t think so. I’ve worked in a sewage plant and there ain’t much will survive that process in great quantities. Most of the content is just water.
So you tested the water for chemical elements? I’m not sure I understand what you mean by ‘most of the content is just water’. They’ve already found Prozac and Viagra in tap water in NYC. Why wouldn’t Tamiflu elements come through?
You didn’t think I mean big hunking peices of the medicine did you?
Here is the information;

The premier flu-fighting drug is contaminating rivers downstream of sewage-treatment facilities, researchers in Japan confirm. The source: urinary excretion by people taking oseltamivir phosphate, best known as Tamiflu.
There are several other sources, but this is the first one I came across. Microbeworld is where I read it though.
