Swimming Pools Are Public Toilet Bowls for Many:
If you're taking a refreshing dip in a pool with four other people, odds are one of you is urinating. This is not gross-out myth, but cold, depressing fact from a recent survey conducted by the Water Quality & Health Council, a scientific research group sponsored by the American Chemistry Council.
The survey, conducted in April, asked nearly 1,000 adults whether they urinate in pools. One in five bravely admitted their mistakes. And those are the ones who admitted it.
The high risk offenders, according to the Center for Disease Control, are those water recreational parks, a dangerous combination of packs of young swimmers and lots of accidental gulps. One targeted study by Georgia's Division of Public Health found that e.Coli infected at least 26 people at one water park in the summer of 1998, ultimately resulting in one fatality. Another study found the parasite Cryptosporidium survives even well-chlorinated water parks, posing a potentially fatal threat to those with lowered immune systems.
But small private pools and large public ones are also potential health hazards, depending on how they're maintained. The CDC notes a rapid rise in gastro-intestinal illnesses borne from dirty swimming pools across the country in the past two decades.
To find out of your pool is safe, look for some tell-tale signs of bacteria.
"Check if you see the bottom," says Dr. Wiant. "If a pool is clear it's likely very clean and balanced, but if it's it cloudy or the sides are slimy, those are signs that bacteria is prevalent and the pool isn't filtering out germs the way it should."
Hyper-vigilant swimmers can also purchase pool test strips at any drug store and do their own scientific assessment. "They're easy to use," he adds, "just crack one open and dip it in the pool and you'll be able to tell right away if the pool is clean."
Another signal it's time to get out of the pool: burning, stinging eyes. Although it's not seriously harmful, when "urine combines with chlorine it becomes an irritant," Wiant says. So if you find yourself squinting in pain after a dive, ask yourself why that person doing the backstroke in the next lane looks so relaxed. It's not that nice of a day.
