I personally think using treated sewage for growing livestock crops is a good idea.
I understand if you have certain manufaturing in your city there is a chance of heavy metals contamination, which is a bad thing.
In the past one couldn't grow human foods for a year from land that had sewage applied; not sure if those regulations changed but it seemsa good idea anyhow.
From the wording of the original message, it's possible in this case the waste has not been properly treated but is an emergency deal where they are picking the lesser of 2 evils - spread it somewhat raw or let it seep raw into a waterway? It would bug me too I guess if I were deemed the lessor of 2 evils in that way.

In any event, like you say, not to question the original intent of this thread, just my calm opinion since you asked.
Another story - there was one of those TV news hound stories on the Twin Cities TV a couple years ago. A homeowner was all aghast that the meadow grass field next door to him was used for spreading septic tank pumpings. It was done according to code, with full inspections; but this couple was just increadulous about it. He kept saying his young daughter went over to the meadow to play all the time, and he didn't want her exposed to all that.
I guess some of us will see that issue one way, and others will see it a different way. Myself, I found it sad that 'dad' was teaching his daughter to tresspass just because the pretty meadow was there - and found it odd he would get on TV and admit such a thing.
