    Knowledge is power! Even if that knowledge causes you to rethink some of those lovely summer memories.

    Summary: I visited Lindsay Blackstock at the University of Alberta to learn about her ingenious method for measuring the amount of pee in a pool by looking at the concentration of an artificial sweetener called Acefulfame Potassium. We looked at some samples from some pools in my area to determine how much pee was in them and I conducted an experiment of my own to see what was the cause of that "classic pool smell". I also presented average amounts of pee in large pools as well as an equation to determine how much pee is in your own pool.

The fact that the pool smell is caused from pee is never going to leave my mind

Growing up, our friends had a pool. They had a sign: “We don’t swim in your toilet, don’t pee in our pool”.

Can you imagine how awkward it was for him to walk around the airport with about 6 bottles of different types of pool water 😂

When I was on a cruise some years ago, I sat by the pool bar having drinks.

Mark, could you revisit this considering the nitrogen content in proteins such as hair and skin that could form trichloramine that would give the smell too?

The fact that he was skeptical and went out of his way to test the smell of chlorine vs trichloramine is why I just subscribed. A+ content. This is an excellent display of scientific literacy.

Thank you, never was a fan of pools or swimming, now this has cleared up any of my doubts of whether I should go into the water ever again.

I am never gonna see and smell other pools the same way again. Thank you Mark and Lindsey for that wonderful experiment.

Moral of the story: Don't pee in the pool because you'll give people asthma.

I wish you would have also consulted a certified pool cleaner as well. The reason your results were skewed was because you pulled from the top layer of water. In order to properly test a pool you need to get samples from 18" deep. The water may not have been changed recently but they could have filled it or it could have rained. In order to get rid of that smell is... wait for it... more chlorine. Would love to see this again with say Scott Ford there would be so much more useful information about pools too. Anyway love your work.

Could that "pool smell" also be caused by sweat? The reason they couldn't test the amount of urine is because sweat has the same chemical makeup. Wouldn't that lead to the same conclusion that sweat also reacts in the same way with the chlorine as urine?

Mark: asthma is more likely to occur in elite swimmers

Note to Self: If pool smells like chlorine - enjoy swimming in pee water.
