Healthy and Safe Swimming

Protect yourself and others from recreational water illness

Recreational water illnesses (RWIs) are caused by germs and chemicals found in the water we swim or play in, including swimming pools, water parks, hot tubs, splash pads, lakes, rivers, or oceans. They are spread by swallowing, breathing in mists or aerosols of, or having contact with contaminated water. Visit the Centers for Disease Control's Healthy and Safe Swimming webpage for more information.
