1 in 5 Americans admit to peeing in the pool.

Americans, urine trouble! From LiveScience:

One in five people admitted to peeing in a swimming pool, in a recent poll of Americans.

In fact, the survey conducted by the Water Quality and Health Council found that almost half (47 percent) of the subjects admitted to one or more behaviors that contribute to an unhealthy pool.

Here are some of the survey's other findings:

• About one-third (35 percent) say they don't shower before entering the pool.
  
• 63 percent were unaware of illnesses associated with swallowing, breathing or having contact with contaminated pool water.
  
• Less than one quarter consider the frequency of pool cleaning and chemical treatment (23 percent) and even less (16 percent) think about chlorine levels to maintain clean pool water.

"Swimming is a fun and healthy activity for old and young alike. Proper water chlorination helps protect swimmers from germs that can make swimmers sick," said Michele Hlavsa, an epidemiologist in the Division of Parasitic Diseases for the Centers for Disease Control and Prevention (CDC). "But swimmers also have role to play in maintaining a clean and healthy pool. Unhygienic behavior brings germs into the pool and makes it harder for chlorine to do its job.”
