State Removes Cyanobacteria Warning for Otternic Pond, Hudson, NH
Concord, NH – The cyanobacteria cell concentration in Otternic Pond, Hudson, NH, is below a level of public health concern. As a result, the New Hampshire Department of Environmental Services (DES) has removed the cyanobacteria lake warning issued on August 1, 2014.
Samples collected and examined August 21, 2014, had no visible signs of cyanobacteria. However, once a bloom has been seen in a lake, that lake is more likely to have future blooms. Please continue to monitor your individual shoreline for changing conditions and avoid any large amounts of growth in the water.DES routinely monitors public beaches and public waters of the state for cyanobacteria, a natural component of water bodies worldwide, but 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 problems (skin irritation, nausea, vomiting, and diarrhea) and chronic problems (liver and central nervous system damage).
