Our team's project is related to using microbes to filter nano-silver out of waste water going through sewage plants. We were "unofficially" told (by VA-DC staff) that since nano-silver was the actual contaminant (not the waste water itself), that we should be fine.
Can I get a final go/no-go on this?
The team is currently looking at experiments with various silver filtration methods.
I would like a final, authoritative answer to this question.
The exception rule indicates Sewage (Ex. waste water, human or animal excrement) should not be included. I would not considered trace water waste water unless it has excrement or goes through a water treatment plant. If the trace water is free of excrement and is not treated, it should be good to explore.

Subject: [VADCFLL-L] project research question
One of our FROGBOTICS teams wants to know if they can "trace" run off into water / streams as a pollutant for their project?
One of our students has done quite a lot of research on it , so please let us know asap.
