Nearly 40 beaches closed in Massachusetts on Tuesday

On a sunny and warm Tuesday across Massachusetts, nearly 40 beaches were closed, mostly due to bacteria in the water, according to the state’s public water quality panel.

In total, 39 beaches across Massachusetts were closed as of the dashboard update at 9:30 a.m.

The closures ranged from Great Barrington in western Massachusetts to Boston in eastern Massachusetts and beaches on Cape Cod and the islands. Of the 39 beaches closed in the state as of Tuesday morning, nearly all (29 of the 39) were attributed to excessive bacteria in the water.

The remaining ten closures were attributed to harmful cyanobacteria blooms, sewage overflows and “other.”

In Great Barrington, Lake Mansfield was closed, though the dashboard listed only “other” as the reason. In the eastern part of the state, Tenean Beach in Boston was closed, as were three beaches in Salem: Camp Naumkeag, the back side of Children’s Island and Ocean Avenue.

On the Cape, two beaches in Chatham were closed because of excessive bacteria, the same reason given for the closure of Washington Street Beach on Nantucket. Miacomet Pond on Nantucket was also closed Tuesday, with the monitoring board saying the cause was a harmful cyanobacteria bloom.

“If a beach is closed, do not swim or enter the water there to avoid the risk of getting sick,” the panel warns.

The dashboard is updated twice a day, once in the morning and once in the afternoon, and displays the results of water quality tests recently conducted at beaches across the state. More than 1,100 public and semi-public beaches in the state are monitored regularly.

And despite the closures, state officials say beaches remain perfectly safe for recreational activities other than swimming.
