More than half of America’s beaches contain potentially dangerous levels of feces, according to a new report described as ‘troubling’ by experts.
Testing carried out at more than 3,000 beaches across the country’s coastlines showed that 55 percent had potentially unsafe levels of sewage in their waters at least once last year.
Experts say about one in every 31 people who swim in sewage-contaminated water get sick. Swallowing water laced with feces can cause stomach infections leading to diarrhea, abdominal cramps and vomiting, while bacteria in the water can also colonize the skin raising the risk of skin and ear problems.
One in nine — or 363 — beaches were so dirty that they had potentially unsafe levels of sewage in their water on at least 25 percent of days that testing took place.
Southern states along the Gulf Coast — including Florida, Texas and Louisiana — were the worst affected, with 84 percent of their beaches having at least one day in 2022 when the water was contaminated with feces.

In recent years, there have been warning signs over the deteriorating health of the seas. In March, Florida faced a gigantic 5,000-mile-long blanket of rotting seaweed across its shores. The seaweed deaths were caused by toxic red algae, which proliferate when waters become nutrient-rich — such as when sewage is spilled into them
There have been concerns over the quality of water at American beaches — visited 400million times annually — for years.
In 2020, the group estimated that 53 percent of beaches had potentially unsafe levels of feces in their water at least once while in 2019, the figure was 56 percent.
Congress cleared $11.7billion for repair work to sewage systems and for constructing new stormwater drainage systems in 2021, although this is yet to help drive down water pollution. The Environmental Protection Agency (EPA) estimates some $271billion is needed.
John Rumpler, the clean water program director who led the report, told DailyMail.com: ‘What we CAN say is that several factors all mean that this beach pollution is likely to continue and perhaps get worse unless bold action is taken to address it.’
The factors he pointed to were aging sewage systems, sprawling impervious surfaces from urban areas and climate change making intense storms more likely.
He added to Fox News: ‘While the data do not allow us to say whether beach pollution is worse now than in some prior years, there are several troubling trends that increase the likelihood of beach pollution.’
Feces can be swept into the sea after storms, with rainwater causing drains and sewage systems to overflow and spill their contents. It can also be carried into the sea by rivers that pick up manure from industrial farms.
People who swim in water contaminated with sewage can ingest the waste — and its dangerous bacteria — by swallowing the water, breathing in mists or aerosols at the water’s surface or having their skin colonized.
The data on the state of US beaches was compiled by Colorado-based pressure group Environment America for its annual ‘Safe for Swimming?’ report.
It was based on figures from the National Water Quality Monitoring Council, part of the Environmental Protection Agency (EPA), which tracks water quality at beaches across the United States.
A total of 3,192 beaches were included in the report. On average, states test the water at their beaches for sewage contamination about once a week.
The second most contaminated beaches in the US were along the West Coast — in California, Oregon and Washington — where 70 percent of beaches were polluted at least once last year.
Beaches surrounding the Great Lakes — like those in Wisconsin and Illinois — were the third most polluted, with 63 percent having feces detected at least once last year.
Oregon had the most polluted beaches in the United States, with half of its counties — three of six — having beaches that were too dirty for swimming from six months to 12 months of the year.
Environment groups say that farming in the state is to blame for the contamination. The EPA has been urging Oregon to clean up its act for years, with a report finding last year that 95 percent of the state’s lakes are now too polluted to be used for drinking water.
At the other end of the scale were Alaska and Hawaii, where 24 percent of beaches had unsafe levels of pollution at least once a year.
In the report, the experts have included a graphic on the beach water quality in each state. Shown above are the measures for Oregon (left) and Wisconsin (right) in 2022

Earlier this year more than 200 dead dolphins and sea lions washed ashore in California. This was likely caused by an algal bloom out at sea, it has been suggested
There have been several signals of problems with water at beaches across the US just this year.
In July, more than 200 dead dolphins and sea lions washed ashore across beaches in California with hundreds more beached in distress.
Experts believe the disaster was triggered by an algal bloom on the west coast, which can be caused by an explosion of nutrients in the water — such as that caused by sewage.
In March, a gigantic 5,000-mile blanket of rotting seaweed — dubbed the ‘red tide’ — was washed onto the shores of Florida.
Residents were quick to complain of burning eyes and breathing problems, while dead fish were also reported to have washed up onto the beach.
The area was facing a flare-up of toxic red algae, which had caused the seaweed deaths. The blooms are caused by a build-up of nutrients in the water such as nitrogen, which can also be linked to sewage dumps.
To minimize beach pollution, Environment America recommended boosting investment in systems to prevent or reduce runoff from urban areas.
This could include installing features such as permeable pavement and adding more green space and even ‘green roofs’ to neighborhoods.
Sewage systems should also be repaired and modernized, they said, to stop them from overflowing and polluting waterways.
The experts also called for more work to be put in to protect wetlands, which can reduce contamination by absorbing flood waters and filtering out pollutants.
