Right but apparently that doesn't kill me. The question is what happens to industrial runoff in the water stream and if that has any effect on food safety.

I think (someone correct me if I'm wrong) US stormwater / runoff systems have to be isolated from sewer systems. Maybe an EPA requirement?

So reclaimed water is typically dealing with "anything anyone puts down a piped drain in their house."

(That said, I think there are also runoff processing requirements before discharge into waterways too)
