Pee isn't so bad. You could actually drink pee in a survival situation. It is gross to think that you are bathing in peed in pools, but htat is the reality of it.
Poop is a whole different story. There are many bacteria in poop. Some can cause very seroius diease. The chemicals in the pools will kill most of it, but too many poops in the pool is not good.
Bottom line, keep you mouth closed, ears plugged and say a prayer.
