Southampton’s Old Town Pond has blue-green algae: officials

Because of the confirmed presence of blue-green algae, residents are asked to avoid using Old Town Pond in Southampton, Suffolk County health officials said Friday.

Pets and children should be kept away from the area, officials said.

Similar precautions should be taken with other locations with blue-green algae: Agawam Lake, Southampton, and Lake Ronkonkoma. In addition, extra care should be taken to avoid direct exposure at Mill Pond, Southampton, and Marratooka Pond, Mattituck, where algae levels and associated toxins are “very high.”

Any water looking “scummy or discolored should be avoided,” officials said in a news release. If contact does occur, rinse off with clean water and see a doctor for symptoms that can include nausea, vomiting or diarrhea; skin, eye or throat irritation; allergic reactions or breathing difficulties, the health department said.

Blue-green algae, also known as cyanobacteria, is naturally present in low numbers, but can increase, forming blooms of green, blue-green, yellow, brown or red, as well as floating scum, the county health department said.
