New Cyanobacteria Blooms in Mattituck and Southampton

Written by Long Island News & PR  |  13. June 2016

Mattituck / Southampton, NY - June 10, 2016 - Sampling performed by SUNY Stony Brook has confirmed new cyanobacteria blooms, more commonly known as blue–green algae, in Lake Maratooka in Mattituck, Agawam Pond and Wickapogue Pond in Southampton, NY.

Currently, cyanobacteria blooms exist at the following Suffolk County locations:

  • Maratooka Pond, Mattituck
  • Agawam Pond, Southampton
  • Wickapogue Pond, Southampton
  • Wainscott Pond, Wainscott

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 mostly typically in shades of green but also in shades of 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 that is in a body of water that does not contain a Suffolk County permitted bathing beach, contact the Division of Water at New York State Department of Environmental Conservation (DEC): 518-402-8179 between 8:00 am – 4:00 pm or anytime via email
