I also wanted to add one more thought to this very unusual topic. Have you considered the animals and wildlife that drink from those streams? While urine is not toxic, humans find it to be a "pollutant" animals do not seem to take much notice, HOWEVER, when you put a toxic substance into an animals drinking water, that animal has a GREAT chance of suffering a horrible death. Have you ever read what gasoline in an animals system can do to them? It is disgusting. You pronounce your Christianity repeatedly, we will see what your god thinks of you harming his innocent creatures when your time comes.
I am not a Christian, not really anything actually, but I love the world I live in, and I love the animals that are in it. I tend to like them more then people. What you are doing is murder. Last time I checked, god wasn't okay with that.
