How NJ Beach Water Quality Is Monitored
New Jersey tests beach water for bacteria like enterococcus, especially after heavy rain. The state and local health departments publish results to help swimmers decide when it is safe to enter the water.
When Water Quality Alerts Are Issued
Advisories or closures are issued when bacteria levels exceed safe limits. Common causes include stormwater runoff, sewer overflows, and high tides that push contaminants near the shoreline.
Tips for Checking Beach Water Quality Before You Go
Visit official NJDEP or county beach program pages for current test results. Avoid swimming near pipes, drainage outlets, or within 24 to 48 hours after heavy rain. For more information on beach monitoring and safety, see NJ Beach Water Quality Monitoring.
