The bacteria itself is typically harmless—it's what it signals that matters.
Each summer, the sea offers its invitation — but not always without condition. Along the shores of Ocean and Cape May counties in New Jersey, routine water testing in late June revealed elevated enterococci bacteria at five coastal beaches and one freshwater lake, prompting state advisories that ask swimmers to pause before entering. The bacteria itself is a messenger, signaling that unseen pathogens may be present, and the state's careful protocol — advisory first, closure only after repeated failure — reflects a measured faith that vigilance can hold the line between risk and harm.
- Five popular summer beaches in Ocean and Cape May counties have been flagged for fecal bacteria levels that exceed New Jersey's safety threshold of 104 colonies per 100 milliliters.
- Enterococci are not the danger themselves — they are the warning sign, pointing toward viruses and pathogens that can cause skin, eye, ear, and respiratory illness in anyone who swims.
- The advisories stop short of closures, leaving beaches technically open while urging caution — a distinction that places the burden of risk squarely on individual swimmers.
- This follows a similar wave of advisories issued just days earlier across Monmouth County, suggesting a seasonal, recurring pattern rather than a single isolated contamination event.
- State officials are collecting additional water samples, and only two consecutive failed tests will trigger an actual closure — a threshold that, as of June 21, no beach had yet crossed.
On a Saturday in late June, New Jersey's Department of Environmental Protection issued swimming advisories at five coastal beaches and one freshwater lake after water testing detected enterococci bacteria above the state's safety limit. The affected sites span Ocean and Cape May counties — Cedar Point Beach and Beachwood Beach West among them — along with three bay-adjacent locations in Lower Township. These are the kinds of places where families anchor their summer weekends.
Enterococci serve as a biological red flag. The bacteria themselves rarely harm swimmers, but their presence in water signals that disease-causing pathogens may also be there — organisms capable of causing skin infections, ear and eye problems, and respiratory illness. Shellfish harvested from contaminated waters carry their own risks. The sources are familiar and diffuse: wastewater discharge, leaking septic systems, stormwater runoff, boat waste, and animal activity.
Under New Jersey's protocol, an advisory is not a closure. Beaches remain open, but swimmers are warned. A closure requires two consecutive rounds of failed testing — a threshold designed to distinguish a temporary spike from a persistent problem. As of June 21, no beach had reached that point.
The episode was not without precedent. Just a week earlier, elevated bacteria had appeared at beaches in Monmouth County and along several river and bay sites. Many of those locations had since recovered after follow-up testing, suggesting the kind of episodic, seasonal contamination that summer routinely brings — and that careful monitoring is designed to catch before it becomes something worse. The water was being watched.
On a Saturday in late June, the New Jersey Department of Environmental Protection posted an alert that would keep some beachgoers out of the water. Testing had turned up elevated levels of enterococci—a bacterium used as a marker for fecal contamination—at five coastal beaches and one freshwater location across the state. The advisories were not closures, but they were a warning: something in the water had crossed a line.
The affected beaches sit in Ocean and Cape May counties, places where families typically spend their summer weekends. Cedar Point Beach and Beachwood Beach West in Ocean County made the list. So did three locations in Lower Township, Cape May County: Wildwood and Bay, Baywyn and Bay, and Ferry and Bay. The state's threshold is clear and unforgiving: no more than 104 enterococci colonies per 100 milliliters of water. When samples exceed that number, an advisory goes up. When they fail twice in a row, the beach closes entirely. As of mid-June, no beaches had reached that second threshold—no closures had been ordered.
The New Jersey Department of Environmental Protection, working with the Department of Health and local officials, tests these waters regularly. It is routine work, unglamorous but essential. The bacteria they hunt for tells a story about what else might be lurking in the water. Enterococci themselves are typically harmless to swimmers, according to the EPA. But their presence signals danger: viruses, bacteria, and protozoa that cause real illness. Swimmers can develop skin infections, eye infections, ear infections, respiratory problems. People who eat shellfish harvested from contaminated water face illness too.
The sources of enterococci are mundane and varied. Wastewater treatment plants discharge it. Septic systems leak it. Stormwater runoff carries it. Boats dump it. Animals—domestic and wild—contribute it. Any of these could be the culprit at the New Jersey beaches, though the state has not yet identified which.
This was not an isolated incident. A week earlier, on June 16, elevated bacteria had been detected at three ocean beaches in Monmouth County and six river and bay locations along the Jersey Shore. Many of those sites had since returned to acceptable levels after additional testing. The pattern suggested something seasonal, something episodic—the kind of water quality problem that emerges in summer and recedes with time and attention.
The state's protocol is deliberate. An advisory does not mean closure. Closure requires two consecutive failed tests. Until that threshold is crossed, the beaches remain open, though swimmers are warned. Officials continue collecting samples, watching the numbers, waiting for the bacteria to retreat to safe levels. It is a system built on the assumption that these problems are temporary, that the water will clean itself, that vigilance will catch the worst cases before they become public health emergencies.
As of June 21, no beaches were closed. The advisories remained in place. The monitoring continued. Summer was just beginning, and the water was being watched.

Why issue an advisory instead of just closing the beaches outright?
Because the bacteria itself isn't necessarily dangerous—it's a signal. The state wants to give people information without overreacting. Closure is reserved for when the problem persists, when two tests in a row fail. An advisory says: we found something, we're watching it, swim at your own risk.
But people don't always read advisories. They just show up and go in the water.
That's the real problem. The system assumes people are paying attention, that they check the DEP website before heading to the beach. Most don't. They see a sunny day and go.
What actually causes this? Is it sewage?
Could be. Could be a leaking septic system, stormwater runoff after heavy rain, boats dumping waste, even wildlife. The state doesn't always know which source is responsible. That's part of why it's hard to fix.
So these advisories—are they common?
Common enough that the state has a whole monitoring system for it. But they're usually temporary. Most of the sites from the week before had already cleared by the time these new advisories went up.
What happens if someone gets sick?
They might develop a skin infection, an ear infection, respiratory problems. It depends on what pathogen was actually in the water. The bacteria is just a warning sign that other, more dangerous organisms could be there too.
