Ten Atlantic City beaches are under swimming advisories after state water testing found fecal bacteria levels more than three times the legal threshold, and officials still haven't identified the source of the contamination.
The New Jersey Department of Environmental Protection issued health advisories on Aug. 18 for a string of beaches along the Jersey Shore after routine monitoring detected elevated concentrations of enterococci, the bacteria group most commonly linked to sewage and animal waste in coastal water. One beach, States Avenue, tested at 320 colony-forming units (CFU) of enterococci per 100 milliliters of ocean water. New Jersey's safety cap is 104 CFU. States Avenue blew past it by a factor of three.
The advisories remained in effect as of midweek, FOX Weather reported, and the NJDEP said daily testing would continue at all 10 locations until water quality drops back below the state standard.
The flagged beaches span a wide stretch of Atlantic City's shoreline. In addition to States Avenue, the advisory covers Connecticut Avenue, Iowa Avenue, Mississippi Avenue, Missouri Avenue, North Carolina Avenue, Pennsylvania Avenue, South Carolina Avenue, Texas Avenue, and Virginia Avenue beaches. The NJDEP did not release individual test results for the other nine locations, only the States Avenue reading appeared in the agency's public data.
That single number tells the story well enough. At 320 CFU, the water at States Avenue carried bacteria concentrations that the state's own environmental regulators consider a direct health hazard. Swimming in water above the 104-CFU line increases the risk of gastroenteritis, low-grade fevers, and skin or ear infections, according to the New Jersey Environmental Protection Agency.
No illnesses tied to the contamination have been reported so far. But the advisories landed squarely in peak beach season, when Atlantic City draws tourists by the tens of thousands and families count on clean water as a baseline expectation, not a gamble.
The NJDEP has not publicly identified what drove the bacteria spike at these 10 beaches. The U.S. Environmental Protection Agency lists several common sources of enterococci in coastal water: outflow from wastewater treatment plants, leaking septic systems, stormwater runoff, domestic animal and wildlife waste, improper land application of manure or sewage, and runoff from manure storage areas, pastures, rangelands, and feedlots.
Any one of those could be the culprit. None has been confirmed. The state agency has said only that it will keep testing daily until the numbers come down, a process that offers no timeline and no guarantee.
That silence matters. Beachgoers can read an advisory sign. What they cannot do is assess whether the contamination is a one-day anomaly caused by a heavy rainstorm or a recurring infrastructure failure that the state has been slow to fix. Without a confirmed source, the public is left guessing, and the agency is under no visible pressure to explain.
Under the NJDEP's water quality monitoring program, the affected beaches will be sampled every day until readings fall below the 104-CFU threshold. Only then can the advisories be lifted. The agency has not indicated how long that process typically takes or whether conditions at any of the 10 sites have already begun to improve.
The advisories do not amount to formal beach closures. Swimmers can still enter the water at their own risk. But the state's own health guidance makes clear that doing so carries real consequences, stomach illness, fever, and infection among them.
Atlantic City's economy runs on its beaches. When 10 of them carry a government warning that the water may make you sick, the damage isn't just environmental. It's economic, and it falls hardest on the small businesses, boardwalk vendors, and seasonal workers who depend on a shore season that is already short.
Taxpayers and tourists deserve more than a daily test and a shrug. They deserve an answer about what fouled the water, and a plan to make sure it doesn't happen again.
