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.

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.

One of our students has done quite a lot of research on it , so please let us know asap.
