'Peeing in a pool depletes chlorine and actually produces an irritant that makes people's eyes turn red,' said Michele Hlavsa, chief of CDC's Healthy Swimming Program.
'What you smell [isn't chlorine] are chemicals that form when chlorine mixes with pee, sweat and dirt from swimmers' bodies,' said Chris Wiant, Chair of the Water Quality and Health Council.
The 'fix' is copious chlorine and cutting-off urinators before they unload.
