IIRC they built a treatment plant near the river to catch the nitrates running off from all the dairies in Ontario/Chino. Everything in the area flows down hill north (from the mountains) to south to the river.

Now the dairies are moving out and houses coming in. Don’t know the impact on the river.

The dairies have been gone for quite some time...I'd gather.

I used to live in RVSD...before I moved here. I know the area pretty well.

Thanks-
