Oceans, Lakes, & Rivers | Healthy Swimming | Healthy Water | CDC









In warm weather, oceans, lakes, and rivers are a source of swimming enjoyment across the country each year for about 91 million people over the age of 16 1. CDC’s Healthy Swimming website is heavily focused on swimming in chlorinated and disinfected swimming venues. However, you will find useful information from the Environmental Protection Agency(EPA) and other groups that are focused on natural bodies of water like oceans, lakes, and rivers. Please remember that the steps of healthy swimming  also apply to swimming in these natural bodies of water.
