This 6 Facts Might Make You Quit Swimming in Public Pools

Swimming-pool-people 

As the summer season unofficially kicks off this weekend, millions of people will be flocking to swimming pools for some fun in the sun.

But while taking a dip is a great way to beat the heat, many public pools are crawling with germs -- and, if not treated properly, can pose a major health risk.

Before heading to the pool this weekend, find out what could be lurking in the water -- and learn how to protect yourself and your family.

1 in 5 adults pees in the pool

Though it may seem like a habit most people would grow out of after childhood -- or preferably, never pick up in the first place -- many adults admit to relieving themselves while swimming.

In fact, a 2012 survey conducted by the Water Quality & Health Council found that one in five U.S. adults urinates in the pool.




But as tempting as it may be to avoid drying off and trekking to the bathroom, experts have a clear message: don't do it.

"No matter how easy it is to pee anonymously in the pool, swimmers should avoid doing so and take their children on frequent bathroom breaks," Dr. Chris Wiant, chair of the Water Quality & Health Council, said in a press release.

There’s probably poop in the pool, too

A recent report from the Centers for Disease Control and Prevention found that 1 in 8 public pools, hot tubs, and water playgrounds were shut down because of health and safety violations, including excessively dirty water.

The most common cause of contamination: fecal matter that rinses off children or people who go swimming while suffering from diarrhea.

"Contamination can occur via direct release of formed or diarrheal feces or as much as 10 grams of fecal material can rinse off a young child's perianal surface and into the water," the report states.

Furthermore, the authors note that swim diapers do not completely prevent feces, urine, or infectious pathogens from contaminating the water.


Some bacteria is resistant to chlorine

While chlorine is added to pool water to kill germs that can cause illness if ingested, it takes time to work.

The chemical eliminates most germs in minutes, but some, such as Cryptosporidium, or "Crypto" for short, can live in properly treated pool water for several days.

Most people go swimming without bathing



The 2012 report from Water Quality and Health Council also found that nearly 70 percent of people do not shower before taking a swim in the pool -- adding to the number of germs in the water.

"Swimming is not a substitute for bathing. Too many people unknowingly treat the pool as a communal bathtub," Wiant said in the release. "It may seem counter-intuitive, but it's important to shower before you jump in the pool to help keep swimming healthy for everyone in the pool.

It’s not the chlorine that turns your eyes red



Though it's a commonly held belief that red eyes while swimming means there's too much chlorine in the pool, that's not the case, health officials say.

It turns out, red eyes (and an irritated nose or throat) after spending time in a pool is a direct result of bodily fluids in the water -- including urine, feces, and sweat.

That “chemical smell” isn’t what you think it is

A recent survey from the Water Quality and Health Council found that three-quarters of Americans incorrectly believe that the strong, chemical smell at many public pools is a sign that there's too much chlorine in the water.
However, that distinct smell is usually a sign that there's not enough chlorine, officials say.
When the chemical combines with urine, feces, sweat, and dirt from people's bodies, irritants called chloramines are produced and give off a chemical odor. These chloramines use up the chlorine, meaning there is less of it to kill germs.
"It's understandable why most people think that a chemical smell means there is too much chlorine in the pool, but the truth could be the opposite," Wiant said in a statement.



You can keep yourself and others around you safe by following a few golden rules while swimming, officials say.

First, never go swimming if you're suffering from diarrhea, and always shower before entering a pool. Parents should also check children's diapers and take them for regular bathroom breaks every hour.

And when it comes to making sure the water is safe to swim, take matters into your own hands. Pool goers can use a test strip -- available at most pool-supply stores, or free on the Water Quality and Health Council's Healthy Pools campaign website -- to determine if the pH and free chlorine or bromine concentration are correct. The CDC recommends the following levels:
  •     Free chlorine concentration of at least 1 ppm in pools and at least 3 ppm in hot tubs/spas.
  •     Free bromine concentration of at least 3 ppm in pools and at least 4 ppm in hot tubs/spas.
  •     pH of 7.2-7.8.
