Several New Jersey beaches have been temporarily closed this season after water tests revealed elevated levels of fecal bacteria. Health officials issue swimming advisories and full closures when samples show increased enterococcus or similar indicator organisms.
Below is a quick reference for beach status, followed by detailed sections on health impacts, monitoring methods, and visitor guidance.
| Beach | Town / County | Closure Reason | Status |
|---|---|---|---|
| Shark River Beach | Neptune, Monmouth | Consistently high enterococcus | Closed until further notice |
| Hackensack River Park Beach | Fairview, Bergen | Combined sewer overflow risk | Posted advisory; limited access |
| Laurence Harbor Beach | Old Bridge, Middlesex | Stormwater runoff spikes | Intermittent closures |
| Mystic Island Beach | Little Egg Harbor, Ocean | Elevated bacteria after rain | Advisories, partial closures |
| Leonardville Beach | Spring Lake, Monmouth | Unknown source contamination | Closed, water testing ongoing |
Health Risks of Swimming in Bacteria-Contaminated Water
Exposure to high bacteria levels can lead to gastrointestinal illness, skin infections, eye irritation, and respiratory symptoms. People with weakened immune systems, children, and older adults are at higher risk for more serious complications.
How NJ Monitors Beach Water Quality
State and local agencies collect water samples weekly along the coast and test for enterococcus bacteria. Results determine posting of advisories, partial restrictions, or full beach closures to protect public health.
Sources of Bacterial Pollution on NJ Beaches
Major sources include stormwater runoff carrying pet waste and trash, aging sewage infrastructure overflows, wildlife contamination, and improper septic system discharges. Rain events often lead to rapid spikes in bacteria levels.
Current Hotspots and Seasonal Patterns
Certain areas, especially inlets, river mouths, and urban-adjacent beaches, experience repeated issues. Warm, stagnant water and combined sewer systems contribute to persistent bacteria problems during summer months.
Protecting Public Health and Beach Access
Targeted infrastructure upgrades, green infrastructure for stormwater control, and ongoing monitoring help reduce closures. Residents and visitors play a role by minimizing pollution sources and heeding posted advisories.
- Check water quality reports before visiting any New Jersey beach.
- Avoid swimming for at least 24 hours after heavy rain.
- Do not feed wildlife and properly dispose of pet waste.
- Support local initiatives that upgrade aging sewer and stormwater systems.
FAQ
Reader questions
Which beaches in New Jersey are currently closed due to bacteria?
Shark River Beach in Neptune and Leonardville Beach in Spring Lake remain closed, while Hackensack River Park Beach and Laurence Harbor Beach have posted advisories with limited access. Closures are triggered by repeated high enterococcus readings.
How can I check if a beach is safe for swimming today?
Visit the New Jersey Department of Environmental Protection beach status page or your local health department website for same-day results. Many municipalities also post real-time alerts via email or mobile apps.
What should I do if I swam in bacteria-contaminated water?
Dry off thoroughly, shower with clean water, and monitor for stomach cramps, diarrhea, fever, or skin rashes. Seek medical attention if symptoms persist, especially if you have underlying health conditions.
Are certain beaches more likely to have bacteria problems than others?
Yes, beaches near stormwater outfalls, marinas, and urban centers, as well as those downstream of rivers and inlets, tend to have higher readings. Coastal geography that limits flushing can increase risk during warm weather.
