A new survey revealed 40 percent of adults that said they've peed in a swimming pool - and that's not the worst of it!

The survey by the Water Quality & Health Council found 24 percent of Americans say they would go into a pool within an hour of having diarrhea. Despite rules to the contrary, 48 percent report they never shower before swimming.

The study said more than half of those surveyed said they use a pool as a "communal bathtub," either swimming instead of showering or using the pool to rinse off after doing yard work or exercising.

Showering makes a difference, because when the dirt, sweat and personal care products on our bodies react with chlorine there is less chlorine available to kill germs in the pool.

Chlorine is effective, but it's not magic. It doesn't kill everything and what it does kill isn't instant.

While well-maintained pools are generally safe, it's a good idea to wear goggles, avoid swallowing water and shower after you get out of the pool, too.

The Water Quality & Health Council is offering free pool test kits, noting that only 1-in-5 Americans reports ever using a kit to check chlorine levels and pH in a public swimming pool. Click here to sign up to get your test kit.
