"The amount of urine a swimmer can introduce into the water is small compared to the amount of urea coming off their unwashed body" - really? how much urea does a normal human have on their body, assumed they wash at all e.g. if they showered this morning, and go to pool after work ? Assuming they don't spend the day pissing on themselves, do we just secrete urea?

Yes, we do (a little bit).

Also remember the number of people getting in the pool is likely much larger then the number of people peeing in it.

That's weird, because the only reason to go to a public pool is so you could pee in it.
