Fecal bacteria levels exceed safety limits at five New Jersey beaches, health officials warn
Health authorities have issued swimming advisories for five coastal locations across New Jersey after water quality tests detected elevated concentrations of fecal bacteria. The New Jersey Department of Environmental Protection confirmed on June 21 that samples collected from beaches in Ocean County and Cape May County exceeded state safety thresholds for enterococci bacteria. The advisories affect Cedar Point Beach and Beachwood Beach West in Ocean County, along with three sites in Lower Township, Cape May County: Wildwood and Bay, Baywyn and Bay, and Ferry and Bay.
State regulations establish a maximum threshold of 104 enterococci colonies per 100 milliliters of water. When test results surpass this limit, officials issue a swimming advisory and collect additional samples until bacteria levels return to acceptable ranges. Despite the advisories, none of the affected beaches have been closed to the public. Under New Jersey rules, beach closures occur only after two consecutive samples fail to meet water quality standards.
Understanding enterococci bacteria and health risks
Enterococci serve as indicator organisms that help measure water quality at recreational swimming sites. The U.S. Environmental Protection Agency notes that while these bacteria are typically not harmful to humans, their presence signals potential contamination from other disease-causing microorganisms. Pathogens that may coexist with enterococci include viruses, bacteria, and protozoa capable of causing infections affecting the skin, eyes, ears, and respiratory system.
Several sources can introduce fecal bacteria into coastal waters. Wastewater treatment plant discharges, leaking septic systems, stormwater runoff, sewage released from recreational boats, and waste from domestic animals and wildlife all contribute to elevated bacteria levels. The EPA cautions that consuming seafood harvested from contaminated waters may result in illness, making water quality monitoring essential for public health protection.
Monitoring protocol and testing frequency
The Department of Environmental Protection conducts regular water testing at New Jersey’s public recreational bathing beaches in collaboration with the New Jersey Department of Health and local health officials. As of June 21, the department’s monitoring dashboard showed no active coastal or freshwater closures statewide. The current advisories represent a significant improvement from the previous week, when elevated fecal bacteria levels were detected at three ocean beaches in Monmouth County and six river and bay locations along the Jersey Shore on June 16.

Recent testing results show improvement
Many of the sites flagged during the June 16 testing round returned to acceptable levels following additional water quality assessments. This pattern demonstrates the dynamic nature of coastal water quality, which can fluctuate based on weather conditions, tidal patterns, and proximity to pollution sources. The rapid improvement at several locations suggests that contamination events may be temporary, though continued monitoring remains necessary to ensure public safety.
The distinction between swimming advisories and beach closures carries important implications for beachgoers. Advisories serve as warnings that water quality has temporarily declined, recommending that swimmers exercise caution or avoid contact with the water. Closures, in contrast, represent mandatory prohibitions enacted when bacteria levels pose a more serious health risk. The current advisory status at the five affected beaches means visitors can still access the shore, though swimming is discouraged until water quality improves.
Ongoing surveillance and public safety measures
Environmental officials will continue monitoring the affected locations and collecting additional samples until bacteria levels consistently meet state standards. The testing protocol ensures that beaches remain safe for recreational use while providing timely warnings when water quality deteriorates. This systematic approach balances public access to coastal resources with health protection, giving authorities the flexibility to respond quickly to changing conditions.
The current advisories highlight the importance of routine water quality surveillance at popular swimming destinations. Summer travelers planning visits to New Jersey beaches can check the Department of Environmental Protection’s monitoring dashboard for real-time updates on water quality conditions. Officials encourage beachgoers to heed posted warnings and avoid swimming at locations under advisory status until testing confirms that bacteria levels have returned to safe ranges.
