Marlborough – Officials have announced that Memorial Beach is temporarily closed for swimming due to elevated levels of cyanobacteria (blue green algae) bloom. The problem is not uncommon; it has occurred in other parts of the state recently as well.
According to a press release, the city of Marlborough is working closely with the Massachusetts Department of Public Health to monitor the cyanobacteria levels at the beach. The formation of a scum layer and visibly stronger blue-green hue throughout the water column yesterday warranted the issuance of a Health Advisory by the city's Board of Health. Water samples were taken by the state for analysis. While Memorial Beach is only closed to swimming, officials advise boaters and beachgoers to exercise personal discretion and caution at this time. Samples will continue to be taken until the water is safe for recreational use. Officials remind residents that even if there is no longer a visual buildup present, cyanobacteria levels may still be above guideline levels.
