Oh! I see what you did there, yes, very clever.
Honestly, I think the hubbub about drinking water (and the things found within it) point to the fact that we need to find a better way to recycle it more than anything. I mean, the drugs and what-have-you that we’ve been finding come from when people wash left over meds down the sink and, um, once they’ve been used. We really can’t clean the water well enough to get that stuff out again? Really? What else is being left in post-use?
(Seriously, the worries about things like drugs in the drinking water or whatever else simply reinforce where they entered the stream to me.)
