The New York State Department of Environmental Conservation has confirmed the emergence of new cyanobacteria blooms, more commonly known as blue–green algae, in Poxabogue Pond and Old Town Pond in Southampton.  In addition, cyanobacteria blooms have re-emerged Wainscott Pond in Southampton.

Currently, cyanobacteria blooms are still present at Lake Agawam, Sagg Pond, Wickapogue Pond, Coopers Neck Pond and Little Fresh Pond in Southampton; Mill Pond in Watermill; Georgica Pond in East Hampton; Artist Lake in Middle Island; South Merritts Pond in Riverhead; Roth Pond on SUNY Stony Brook Campus; Lake Ronkonkoma, and Babylon Town Hall Pond.

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. 


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.
