You're in Urine

Researchers say it's staggering how many people are peeing in pools.

any pool that has people in it, also has urine in it,

--Ernest Blatchley III, an environmental engineer at Purdue University

The average swimmer leaves about roughly the equivalent of a shot glass (1 to 2 ounces) of urine in the pool

But Its Not Just ONE Person peeing in The POOLS

Estimated 20 Gallons of Urine would be in a 220,000-gallon pool

--Researches at University of Alberta

This provides us evidence that people are indeed urinating in pools,

--Lindsay Blackstock researcher involved in the Study at Alberta

A recent university study found more than 100 chemicals in pools and hot tubs, some of which are toxic.

urine and sweat can react with chlorine to create toxic compounds known disinfection by-products, or DPBs

there is definitely a risk for asthma from these compounds,

--Susan Richardson, PhD environmental chemist at the University of South Carolina,

Spoting Unhealthy Pools

when your eyes get red in the pool or you smell that classic "chlorine" odor, it’s not due to chlorine.

It’s not the chlorine that is making your eyes red, it is the urine and sweat that combines with the chlorine,

--Michele Hllavas, RN chief of the CDC's Healthy Swimming Program

Scientists are looking

for solutions. Richardson says her team is looking into a promising new treatment that uses silver/copper disinfection and doesn't rely on much chlorine, or potentially no chlorine at all. They are testing it in pools in Myrtle Beach, SC. "From what we can tell so far, it does a great job keeping the water clear and disinfected, without necessarily needing to add chlorine," Richardson says.
