Public vs. Private
A public swimming pool is any indoor or outdoor structure that is intended to be used collectively for swimming, diving, or bathing.
A private residential pool is one located at a private house with no more than three families and used exclusively by those residents or their guests (who are non-paying).
Recreational Water Illnesses
Recreational water illnesses (RWIs) are caused by germs and chemicals found in the water we swim in. They are spread by swallowing, breathing in mists or aerosols of, or having contact with contaminated water in swimming pools, hot tubs, water parks, water play areas, interactive fountains, lakes, rivers, or oceans. RWIs can also be caused by chemicals in the water or chemicals that turn into gas in the air and cause air quality problems at indoor aquatic facilities.
Knowing the basic facts about RWIs can make the difference between an enjoyable time at the pool, beach, or waterpark, and getting a rash, having diarrhea, or developing other, potentially serious illnesses.
