Blue-Green Algae Found In East Marion Lake

EAST MARION, NY — Blue-green algae has been detected in Marion Lake in East Marion, according to the Suffolk County Department of Health Services.

Analysis of surface water samples performed by SUNY Stony Brook has confirmed the presence of new cyanobacteria blooms, or blue-green algae, the SCDOH said.

Due to these findings, health officials ask residents not to use or swim or wade in the water and to keep their children and pets 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, officials said.

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, the SCDOH said.

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. and 4:30 p.m. or by email at any time at scdhsweb@suffolkcountyny.gov.
