New Cyanobacteria Bloom Found in Georgica Pond and Sagg Pond


The New York State Department of Environmental Conservation confirmed this weekend the presence of a new cyanbacteria bloom, also known as a blue-green algae bloom, in both Georgica Pond in East Hampton and in Sagg Pond in Sagaponack. Other blooms have already been reported in Agawam Lake in Southampton, Fresh Pond on Shelter Island, Mill Pond in Southampton, Roth Pond at SUNY Stony Brook, Laurel Lake in Laurel, Maratooka Lake in Mattituck and Wainscott Pond in Wainscott.

Officials from the Suffolk County Department of Health Services are advising residents not to swim or wade in any of these waters and to keep children and pets away from the area. If contact does occur, the DEC advises rising the affected area with clean water immediately, and suggests seeking medical attention if a resident has nausea, vomiting or diarrhea, skin, eye or throat irritation, or difficulty breathing as a result of exposure.

To report a suspected blue-green algae bloom at a body of water that contains a Suffolk County-permitted bathing beach, contact the Suffolk County Department of Health Services’ Office of Ecology at (631) 852-5760 between 8:30 a.m. to 4:30 p.m. or by email at any time at
