How Much Urine Is In The Average Swimming Pool?

We promise we're not taking the piss...

A new study has figured out just how much urine you’ll find in the average swimming pool and it’s an alarming amount.

We’ve all done it at some point in our lives – sometimes you just have to go, right? – and a swimming pool sometimes seems like the best bet. Who would know?

You might expect that the eye-burning chlorine present in the water would take care of human waste immediately. Not so much. Turns out, we are floating in gallons of piss.

Inspired by the mysterious green swimming pool at the Rio Olympics, a group of scientists from the University of Alberta in Canada took samples from 31 different pools to determine the pool to pee ratio.

Alarmingly, one pool had 132 pints of urine in it, and the average pools can contain more than 16 gallons of wee. Gross.

This isn’t good news, despite the sterility of urine, when mixed with pool chemicals it’s a cocktail from hell that could cause conditions as serious as asthma.

‘Urine contains many nitrogenous compounds such as urea, ammonia, amino acids, and creatinine. These compounds can react with disinfectants (e.g., chlorine) in swimming pools to form disinfection byproducts,’ wrote the team of researchers in a paper published in Environmental Science and Technology Letters.

The conclusion reached by the group is that we need to be more aware of the quality of the water we’re diving into and use the flipping toilet before jumping in.

We suggest maybe avoiding public pools until they come up with better pee-removing methods.
