You're mostly spot on but your last sentence is flawed, as it's chloramines that are the problem with pools, not chlorine, and urine is all-too-often the root cause

https://www.chemicalsafetyfacts.org/health-and-safety/how-ch...



From the article, reasons why chloramines get created:

> perspiration, oils and urine that enter pools from swimmers’ bodies.

I choose to be an optimist and will believe that list starts with most common source and ends with the least common.


According to the article, chloramines come from the reaction of pool chlorine with human urine, sweat, and body oils.

It seems like that would still be happening in the absence of urine?
