Reason not to trust competitive swimmers

Via NPR, I was linked to an article in Chemical and Engineering News, talking about the smelly and unhealthy disinfection by-products (DBPs) of chlorinated swimming pools:
But the biggest contributor to DBPs in pools is urine. Researchers estimate that swimming pools contain an average of 30 to 80 mL of urine for each person that’s jumped in. Some of that is released accidentally or without the person realizing.

But for elite swimmers, peeing in the pool is an accepted part of the culture. Eldridge, the Masters swimmer, confirms that peeing in pools is commonplace in elite competitive swimming. It’s a frequent topic of conversation and joking among swimmers.

Practices can last for hours, Eldridge says, and swimmers chug water during stops between intervals. Swimmers rarely leave the pool during that time. “Do you really think that all these people in the pool, exerting at the level they are, drinking as much as they are, don’t have to pee in two hours?” she asks.
Olympic swimmers Michael Phelps and Ryan Lochte have both been captured on video admitting to peeing in the pool and seeing nothing wrong with it. A quick YouTube search turns up multiple such videos highlighting their cavalier attitudes.
