Yeah, and I am in Gwinnett. Perhaps that's contributing to my success (or rather, lack of problems).
I've spent a bit of time trying exactly to find out what IS in waste water anyway. Came up empty handed though. I suppose if there are things that are not removed by the sediment and carbon filters that they'd be more concentrated, but unless I get a better understanding, I still feel it's off to call it 'waste' water.
