How Much Pee Is in a Swimming Pool? Tests Reveal a Grim Truth
Canadian researchers studying urine levels in swimming pools have discovered just how high the levels are, and the results are not pretty, according to an article published on Wednesday.
Researchers at the University of Alberta developed a test to measure the amount of urine and took more than 250 samples from 31 pools and hot tubs in two Canadian cities.
The Grim Truth!
The results showed one 8,30,000 litre pool, which is about one-third of an Olympic-sized pool, had 75 litre of urine, while another, smaller, pool had 30 litre.
Humans introduce "a variety of chemicals" into recreational waters through bodily fluids, and the separate news of an overnight water colour change in the 2016 Rio Olympic pools highlight the need to monitor water quality, according to the study, published in the journal of Environmental Science and Technology Letters.
A Health Hazard?
Although urine itself is sterile, its presence in swimming pools is a public health concern as urine can mix with pool chemicals to harm swimmers' health, according to the study.
When asked about the study, the Alberta Health provincial ministry said it will be taking a "closer look" at it.
Under the Public Health Act, the ministry has a regulation that provides standards,” spokesman Tim Kulak said in an email. “Pools that don’t meet the standards may be closed for remediation.
The Amount of ACE Found
According to the study, researchers measured for the substance acesulfame K (ACE), an artificial sweetener that passes through the body completely, and is "an ideal urinary marker."
It found concentrations of ACE in the pools and tubs, which were not named, that were up to 570-fold greater than that found in normal tap water. Researchers then used the ACE concentration of the two pools over three weeks to estimate their levels of urine, according to the study.
