I was just using that as an example. You are wrong about having “no known pollutants,” though. Pollutants need to be below some agreed-upon level, so they exist but in theory should be below harmful levels. There can be a perceived difference between industrial chemical wastewater and household wastewater and that’s what I was getting at. One is far riskier for a “spill” accident, and more rigorous prevention measures may need to be discussed upfront. The article didn’t differentiate which it’s going to be. I feel like by not differentiating, the article may be somewhat sensationalized. Without knowing which it is, I’m left wondering.
