State Removes Cyanobacteria Warning for Eastern Cove of Big Island Pond, Atkinson, Hampstead & Derry
Concord, NH – The cyanobacteria cell concentration in the eastern cove of Big Island Pond in Atkinson, Hampstead and Derry is below the state standard of 50 percent of the total cells. As a result, the NH Department of Environmental Services (DES) has removed the cyanobacteria warning issued on August 19, 2010.
DES routinely monitors public beaches and public waters of the state for cyanobacteria. DES monitors public waters issued cyanobacteria warnings on a weekly basis until the cyanobacteria standards are again met. Cyanobacteria are natural components of water bodies worldwide, but blooms and surface scums may form when excess phosphorus is available to the water. Some cyanobacteria produce toxins that are stored within the cells but released upon cell death. Toxins can cause both acute and chronic health effects that range in severity. Acute health effects include irritation of skin and mucous membranes, nausea, vomiting, and diarrhea. Chronic effects include liver and central nervous system damage.

If you notice anything resembling cyanobacteria, please refrain from wading, swimming, or drinking the water. Keep all pets out of the water and contact DES immediately. Please call DES to report a cyanobacteria bloom at (603)419-9229.
