Is It Safe To Pee In The Pool? Researchers Say, No
Sanitary-minded pool-goers who preach "no peeing in the pool," despite ordinary and Olympic swimmers admitting to the practice, now have scientific evidence to back up their concern. Researchers are reporting that when mixed, urine and chlorine can form substances that can cause potential health problems. Their study appears in ACS' journal Environmental Science & Technology.
They mixed uric acid and chlorine, and within an hour, both NCl3 and CNCl formed. Though some uric acid comes from sweat, the scientists calculated that more than 90 percent of the compound in pools comes from urine. They conclude that swimmers can improve pool conditions by simply urinating where they're supposed to — in the bathrooms.
