Another algae bloom emerges at Lake Attitash

(Continued)

According to the DPH, exposure to high concentrations of cyanobacteria can cause skin, eye and ear irritations, and occasionally respiratory and gastrointestinal illnesses as well.

As for the origin of the blue-green algae, the Lake Attitash Association believes high levels of phosphorous in the lake is the main cause of the frequent blooms, and over the past year the Environmental Protection Agency has been conducting a study to try to pinpoint the sources of phosphorous in the lake so that a targeted solution can be pursued.

In addition, the Centers for Disease Control has also said that algae blooms can form in the water at any time, particularly in warm, slow-moving waters that are rich in nutrients such as fertilizer runoff or septic tank overflows. The bacteria is also influenced by the temperature and the level of sunlight, making it more difficult to predict how it will behave in the future.
