Oceans, Lakes & Rivers
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 web site 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 Six steps for prevention of recreational water illnesses (RWIs) also apply to swimming in these natural bodies of water.
Checking Water Quality at the Beach
- State Beach Bacterial Monitoring Program Information
- This site posts recent beach monitoring information for coastal and Great Lakes states. Visit this site to find out if selected beaches are open for swimming based on recent bacterial testing results.
- Local Beach Information
- Check out whether bacterial levels in the water are monitored at your local beach and whether the beach is open for swimming (information available from EPA and is only for U.S. coastal/marine and Great Lakes beaches).
- Beach Watch
- EPA's homepage for their beach protection activities includes beach reports, references, action plans, upcoming meetings, and frequently asked questions.
Prevention
- Before You Go to the Beach (EPA brochure) [PDF - 2 pages]
- Since many factors affect the water quality at the beach, it is important for you to know about the environmental conditions that affect water quality. This brochure tells you what you need to know about beach water pollution, the health risks associated with swimming in polluted water, and who to contact if you think the water at the beach is contaminated.
Beach Management
- The Beach Manager’s Manual: Harmful Algal Blooms [PDF - 8 pages]
- Harmful algal blooms, commonly referred to as HABs, are an environmentally complex problem throughout the world. This document discusses HABs, their impact, and prevention strategies for beach managers and community members.
