Pee is sterile and unless you got somethin' nasty from your last one night stand, feel free to water anywhere. #2, on the other hand(and if you got it on the other hand, learn to wipe with paper), should be handled as a biohazard (can you say fecal coloform bacteria). Burry at least 1 foot deep and 100' from the water, 200' is better.

When we were kids, we always caught fish AFTER peeing in the water. Go figure?
