Normally fish live in rivers and the like. It’s a pretty straightforward thing. Here in Albuquerque, we’re building a sort of quasi-river for them instead, on account of the actual river is sort of messed up.
This is the new intake structure, down in the south valley, for the Bureau of Reclamation’s minnow sactuary.
You have no problems. In the 90s I lived in Essen-Karnap, between the garbage burning power plant (sometimes it did not, let us say burn completely), the glass factory, the abandoned coal mines, and the queen of polluted rivers, the Emscher, which was so bad that it was surrounded by fences so that nothing could fall in. Fish or fowl, you did not swim in the Emscher.
The good news is that it is being cleaned up.
