If you find yourself considering some type of water activity at Port Jefferson Harbor Tuesday — or even eating shellfish from there — rethink your plans. The Suffolk County Department of Health Services issued a water warning following reports of a discharge of thousands of gallons of partia lly treated sewage after a malfunction on one of the UV disinfection units.

Health officials say corrective actions to mitigate the discharge have been completed. Officials say they can’t confirm the shellfish lands within the Port Jefferson Harbor complex, including its tributaries, are safe.
