Contaminants may be lurking in beach, lake or 'old swimming hole' water. Local reporting can help readers swim safely.

Want to go for a swim? Sounds appealing, but it's best to see what's in the water before donning your flippers and face mask. 

"A stark 1,930 out of 3,187 beaches sampled across the nation in 2024 experienced at least one day on which indicators of fecal contamination exceeded federal safety levels, a new report has revealed," Sharon Udasin of The Hill reports. "The Gulf Coast had the biggest share of beaches with at least one unsafe day in 2024, reaching 84%, followed by the West Coast, with 79%, and the Great Lakes, with 71%."

The list of diseases swimmers can get from contact with contaminated water includes "cryptosporidium, some forms of filariasis (not elephantiasis), Legionnaires' disease, swimmers' itch, swimmers' ear, typhoid, giardiasis, salmonella, schistosomiasis, campylobacter … and more," reports Joseph A. Davis for the Society of Environmental Journalists. Many of the listed diseases are spread when swimmers swallow fecal-contaminated water. Research confirms almost all recreational water activities cause swimmers to ingest at least a small amount of beach, lake or pool water.

Historically, the U.S. strives to maintain "fishable, swimmable waters. That’s the stated goal of the 1972 Clean Water Act," Davis adds. "The nation certainly hasn’t met the goal yet — but it is still trying. . . . Under the CWA, the Environmental Protection Agency sets nationwide 'criteria.' These state how clean water must be for any particular use (like swimming or total body contact recreation)."

Each state has its own water pollution control agency that determines "specific uses (like swimming) for each lake, stream or estuary within its borders, and regulates discharge permits to reach the criteria for those uses," Davis explains. "That’s the theory, anyway."

For community journalists, reporting on local "water hole" quality could be information readers will appreciate. Story ideas by Davis are shared below:

• Where do people in your audience area go to swim in the summer? How far away are they willing to go? Go there and talk to people.
• Are there beach closings in your area? Why? It’s often storm discharges from sewer systems. What are the records of your local sewage and stormwater agencies on storm discharges? Have they ever been cited for permit violations?
• What do your state and local health agencies say about the incidence of waterborne illness from local swimming areas? Are the diseases common or uncommon?
• Talk to managers and patrons of local pools, public and private. Talk to the swim coaches. Have they ever had a swimmer out because of waterborne illness?
• Are there ever algal blooms in your local swimming waters? Are they harmful?
• Talk to people whose water recreation mainly involves things other than swimming: sailors, skiers, parasailers, etc.
• Is there a community health center near your swimming area? Go there and talk to the staff about water contact diseases.
