State Removes Cyanobacteria Warning for Province Lake, Effingham, NH
Concord, NH - The cyanobacteria cell concentration in Province Lake, Effingham, 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 July 11, 2013.
Areas examined today, July 19, 2013, included areas along Bonnyman Point, Bailey & Remick Roads. The growth has been reduced to small specks throughout the water column, but the overall concentration of cyanobacteria in the samples collected was low. 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. 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.
