Beaches and lakes in at least five states shut their gates to swimmers this month after water tests revealed dangerous levels of fecal bacteria, a coast-to-coast failure of water infrastructure that health officials warn could sicken anyone who wades in.
From the Bronx to the shores of Lake Washington, public health agencies issued closures and swimming advisories tied to elevated enterococci, E. coli, and cyanobacteria. The causes are not mysterious. Officials in New York City pointed to stormwater runoff and aging sewer systems. In Iowa, inland lakes tested positive for E. coli. In Washington state's King County, authorities closed swimming areas and said the shutdowns would last at least a week.
The scope of the problem is difficult to dismiss as a local fluke. FOX Weather reported closures and advisories in New York, Massachusetts, New Jersey, Iowa, and Washington, all during the first weeks of summer, when millions of families head for the water.
In New York City, swimming advisories hit beaches in the Bronx, Queens, and Brooklyn after samples showed enterococci bacteria above state health standards. Waterfront areas along the Long Island Sound and the city's southern coastline were affected. Officials blamed the contamination on stormwater runoff and infrastructure that has not kept pace with demand.
The problem extended beyond the five boroughs. The Washington Examiner reported that three Long Island beaches in Suffolk County, Benjamin Beach in Bay Shore, Sayville Marine Park Beach, and Bayport Beach, were closed to swimming until further notice. Suffolk County Health Commissioner James Tomarken warned that swimming in the contaminated water could cause gastrointestinal illness and infections of the eyes, ears, nose, and throat.
Massachusetts saw 24 beaches close on Father's Day weekend alone. The Massachusetts Department of Public Health reported closures from Cape Cod communities like Brewster, Plymouth, and Provincetown to North Shore towns including Gloucester, Manchester, Rockport, and Salem. Inland swimming areas in Natick, Pittsfield, and Templeton also drew advisories. Sections of Constitution Beach in East Boston were affected as well.
New Jersey's Department of Environmental Protection, which tests roughly 195 ocean stations and 25 bay stations along the coast each week, flagged eight beaches and lakes for high fecal bacteria levels. One beach in Upper Township was shut down entirely. Inland recreation spots in Burlington, Sussex, and Morris counties, including Mirror Lake, Sleepy Lagoon, and Vernon Valley Lake, also received advisories.
In Iowa, the Department of Natural Resources issued "swimming not recommended" advisories for eight beaches after detecting elevated E. coli. Named locations included Backbone Beach in the northeast, Beeds Lake in north-central Iowa, Lake Darling in the southeast, and Black Hawk Lake in western Iowa. Four additional beaches received the same advisory but were not identified by name.
King County health officials in Washington closed several swimming areas around Lake Washington, in Seattle, Kirkland, and Renton, as well as Lake Meridian in Kent. Follow-up testing would determine when those sites could reopen.
The closures are not an anomaly. A 2024 report from the Environment America Research & Policy Center found that 61 percent of U.S. beaches had potentially unsafe contamination levels, Fox News reported. Sources of contamination ranged from urban runoff and sewage overflows to pathogens traced to factory farm operations.
The numbers from the AP paint an even grimmer picture. Nearly two-thirds of beaches tested nationwide in 2024 experienced at least one day with unsafe levels of fecal contamination indicators. The Gulf Coast fared worst, 84 percent of beaches exceeded safety standards at least once, followed by the West Coast at 79 percent, the Great Lakes at 71 percent, and the East Coast at 54 percent.
John Rumpler, clean water director at Environment America, put the stakes plainly:
"These beaches are a treasure for families across New England and across the country. They are a shared resource. We need to make the investment to make sure that literally our own human waste doesn't wind up in the places where we are swimming."
That investment has not materialized at the pace the infrastructure demands. Combined sewer systems, designs that route both stormwater and raw sewage through the same pipes, remain common in older cities. When storms hit, the systems overflow and dump untreated waste directly into waterways. The result is what families encountered this month: beaches that look inviting but carry invisible hazards.
The contamination crisis is not limited to the East Coast or the Midwest. Southern California's Tijuana River sewage crisis has sickened Navy SEALs and shuttered beaches for years, driven by cross-border sewage flows that federal and state authorities have struggled to contain.
The EPA's guidance on contaminated beach water is blunt. The agency states that "swimming, diving or wading in water contaminated with fecal bacteria can result in gastrointestinal illness (such as diarrhea or vomiting), respiratory illness and other health problems." It adds that "skin, ear, eye, sinus and wound infections can also be caused by contact with contaminated water."
Health officials cited by the New York Post went further, warning that swallowing contaminated beach water can cause severe illness, including nausea, vomiting, watery diarrhea, or painful skin and urinary tract infections from enterococci exposure. The Post also noted that eight of 11 New York City beaches along the Long Island Sound received poor grades, D or F, for water quality in a 2025 summer season report.
That detail deserves emphasis. These are not remote stretches of shoreline. They are public beaches in the nation's largest city, graded and found wanting, yet still open to families the following summer until bacteria counts forced officials to act.
Erin Bryan-Millush, of the North Carolina Department of Environmental Quality, described the risk from storm drains: "Those storm drains carry everything. It could be really bad for someone who is immune compromised."
The threat is not confined to saltwater beaches. Freshwater lakes and ponds carry their own dangers, from E. coli to cyanobacteria blooms. And as summer temperatures rise, brain-eating amoeba warnings add another layer of risk at inland swimming holes across the country.
The common thread across every affected state is infrastructure that has not been maintained, upgraded, or replaced at the rate the public deserves. Combined sewer systems in cities like New York were built generations ago. Suburban sprawl has increased impervious surfaces, driveways, parking lots, rooftops, that channel runoff loaded with pet waste, fertilizer, and whatever else sits on the pavement straight into waterways.
Failing septic systems in rural and exurban areas add to the contamination. Factory farm operations contribute pathogens at scale. None of this is new information. The EPA has studied it. State agencies monitor it. Reports quantify it. Yet the pipes keep overflowing, the beaches keep closing, and taxpayers keep arriving at the shore to find warning signs instead of open water.
The situation in San Diego offers a cautionary tale of what happens when sewage problems go unaddressed for too long. Residents near the Tijuana River have been forced to abandon their homes after toxic sewage gas reached 150 times California's safety limit, a crisis that started with contaminated water and escalated into an environmental disaster affecting entire neighborhoods.
Washington, D.C., has spent lavishly on climate-related programs, equity initiatives, and regulatory expansion in recent years. Meanwhile, the basic function of keeping human waste out of swimming water remains unmet in communities from Cape Cod to Puget Sound. The federal government's priorities are visible in its budgets. So are its failures.
For now, the practical advice is straightforward but frustrating. Check local advisories before heading to any beach or lake. State environmental agencies maintain monitoring programs, Iowa's Department of Natural Resources, for instance, runs a beach monitoring site that tracks conditions in real time. New Jersey's DEP tests nearly 220 stations weekly along the coast.
But monitoring is not the same as fixing the problem. Testing tells you the water is unsafe. It does not make the water safe. And closures that last "at least a week", as King County officials projected, can swallow a family's entire vacation window.
The broader pattern raises questions that no state agency has answered satisfactorily. If 61 percent of tested beaches showed potentially unsafe contamination in 2024, and closures are spreading across five or more states in the opening weeks of summer 2026, what exactly has improved? Where did the infrastructure money go? And who is accountable when a family drives two hours to a beach only to find it roped off with a bacteria warning?
Coastal and environmental disruptions may only intensify. NASA satellite data confirms a Super El Niño is building across the Pacific, a weather pattern that historically drives heavier rainfall, and heavier rainfall means more sewer overflows, more runoff, and more closures.
Americans do not ask for much from their government when it comes to public recreation. Keep the parks open. Keep the water clean enough that a child can swim without getting sick. When the system cannot deliver even that, the failure is not technical. It is a failure of basic governance, the kind that no amount of federal spending on fashionable causes can excuse.
