Harmful Bacteria Levels Continue to Rise in Jamaica Pond

Jamaica Pond is no where close to being reopened after another week of testing indicated rising levels of harmful blue-green algae blooms in the water, also known as cynobacteria.

The Boston Public Health Commission closed the pond two weeks ago and according to a report on Wednesday, cynobacteria levels are three times higher than what’s considered to be safely acceptable for humans and animals.

“The results of this sampling indicate that algae levels exceed the state-established 70,000 cells/milliliter. Massachusetts Department of Public Health analysis of the sample taken on July 27th shows cyanobacteria levels of 240,000 cells/mL, above the DPH guideline level of 70,000 cells/mL threshold,” the health commission said.

The spike in the bacteria level is quite alarming, considering last week’s testing found levels to be at 81,576 cells/mL.

Officials say the blooms produce toxins that can make people and pets sick. It some cases, exposure can prove fatal.

As a result of the findings, the ordered ban on swimming, fishing and boating will remain in effect until further notice. Dogs or any other pets are not allowed in the water.

Those who may come in contact with the algae bloom are urged to rinse off immediately.

“The Boston Public Health Commission will continue to review state sampling results for the presence of a algae bloom in Jamaica Pond over the coming weeks. Water sampling will occur at least weekly while the algae bloom persists, and for several weeks after it is no longer visible. DPH recommends that the recreational water advisory not be lifted until two consecutive weekly samples show algal cell counts below the safe limit of 70,000 cells/milliliter of water,” the health commission said.
