Town warns community of algae bloom at Menotomy Rocks Park


The Arlington Board of Health on July 21 issued a public health advisory for Hill’s Pond at Menotomy Rocks Park because of a visible algal bloom.

The board strongly advises residents not to swim or stand in the water and especially urges residents to keep pets away from the water because of the risk associated with a visible algal bloom.

A harmful algal bloom is an overgrowth of algae in a water body that could affect water quality and aquatic life. Some blooms produced by bacteria can create toxins that may also harm people, animals and the local environment. Contact with high levels of a algal blooms has been found to contribute to eye, ear and skin irritation, the board said.

During an algal bloom, the amount of algae and toxin in the water can become elevated and exposure can be potentially harmful to people and animals. Ingestion of elevated concentrations of the algae and its toxin can lead to more serious health effects, such as muscle cramps, twitching and liver damage.
