Do you ever urinate in public swimming pools?

That should be pretty low for health concerns because urine typically has no pathogenic bacteria. There can be all sorts of fungi or bacteria coming from skin, nasal and oral secretions, perineal, and anal sources that end up in the pool water. Given time, the chlorine usually knock them down to a safe level. But if you happen to be swimming right behind someone who snorts in the water, you can have exposure to viable infectious material.

If you want reassurance, ask how often pool maintenance is done and what records are kept. Water pH and chlorine level are the most important factors to test.

I got banned from a public swimming pool for urinating in it. Maybe It was because I was at the top of the diving tower when I did it!
