Sampling performed by SUNY Stony Brook has confirmed the presence of new cyanobacteria blooms, more commonly known as blue–green algae, at Fort Pond in Montauk, Poxabogue Pond in Sagaponack, and Sayre Pond and Coopers Neck Pond in Southampton.
Due to these findings, health officials ask residents not to use or swim or wade in these waters and to keep their pets and children away from the area. This advisory will remain in effect until the concentration of blue-green algae chlorophyll-a meet New York State threshold and the water is not visibly discolored for at least 24 hours.
Though blue-green algae are naturally present in lakes and streams in low numbers, they can become abundant, forming blooms in shades of green, blue-green, yellow, brown or red. They may produce floating scums on the surface of the water or may cause the water to take on paint-like appearance.
Contact with waters that appear scummy or discolored should be avoided. If contact does occur, rinse off with clean water immediately. Seek medical attention if any of the following symptoms occur after contact: nausea, vomiting or diarrhea; skin, eye or throat irritation; or allergic reactions or breathing difficulties.
To report a suspected blue-green algae bloom, contact the Division of Water at New York State DEC: 518-402-8179 between 8:00 a.m. – 4:00 p.m. or anytime via email at firstname.lastname@example.org
