There is no chemical that will turn pool water a different color if you pee in it

We wish it were true but, alas, there is no chemical that turns pool water blue if someone pees in it. At Mel Magazine, Mike Rampton investigates:

“Most pools are 20,000 gallons (91,000 liters) or more, so to make a few ounces of urine show up as a bright color would take some serious chemistry,” says bzsteele, a former pool supplies store employee, who recalls new pool owners asking about the dye. “There are cheap tests that could detect urine, but things like sweat, detergent and lotions would also be likely to spike them, so you’d be thrown off by all kinds of false positives. And once the reaction had happened, I’m not sure how you would undo it and get the pool back to stable.”

There’s also the fact that disinfection byproducts, or DBPs — created when the chlorine in pools reacts with the endless streams of pee released into them — are far more harmful than chlorine or urine would be on their own. Haloacetic acid, trihalomethane and chlorite can all be created by chlorine and organic matter (sweat as well as pee) reacting together, and can lead to respiratory issues, eye complaints, “lifeguard lung” and asthma. Adding more volatile chemicals, then, is unlikely to improve matters. And although pool disinfection techniques that require less chlorine (such as UV light, saltwater and hydroxyl-based systems) are increasingly being taken up by pool owners concerned about DBPs, a color-changing substance to stop people peeing in the pool is still nowhere in sight.

Your chance to swim in a Hearst Castle pool is now

Ever dream of taking a dip in one of those gorgeous pools at Hearst Castle? YES, ME TOO. Well, get out your credit card, because it's going to cost you.

Architectural Digest:

...it will require you to join The Foundation at Hearst Castle with a minimum donation, which helps fund the castle’s art conservation and education programs (and the minimum amount for a members-only swim event is $950). But can you really put a price on the opportunity to swim at this storied San Simeon landmark within the California State Parks system, built for newspaper publisher William Randolph Hearst between 1919 and 1947? Open for only five pool nights this summer and fall (July 6, August 4, August 24, September 21, and October 20), it’s a rare chance to float and frolic where famed stars like Howard Hughes, Joan Crawford, and Charlie Chaplin have. Admission is capped at 40 people, so lucky attendees aren’t elbowing one another for the privilege of swimming in one of America’s most iconic design attractions.
