Boston expands cyanobacteria advisory on Charles River Lower Basin
State health officials found blue-green algae above recreational guidelines in the Charles River, and the advisory now covers all points downstream of Boston University's "Jenga Tower."
Boston health officials expanded a public health advisory Thursday warning people and pets to stay out of the water in the Charles River Lower Basin because of a cyanobacteria bloom.
The advisory now covers all points downstream of Boston University's Duan Family Center for Computing and Data Sciences building, known as the "Jenga Tower," the Boston Public Health Commission said. The expansion was recommended by the Massachusetts Department of Public Health, whose staff tested the river and found cyanobacteria at levels above state guidelines for recreational waters, according to the commission.
The commission said people should avoid swimming and other water activities and stay away from the affected shoreline, including any spots where algae has collected. Dogs should not be allowed to swim in or drink the water. Anyone who touches the water or shoreline algae, including children and pets, should rinse off right away, the commission said.
Blue-green algae can produce toxins that make people and animals sick, health officials said. Contact can irritate skin and eyes, breathing in water droplets can irritate the lungs, and swallowing the water can cause vomiting and diarrhea. In serious cases, the toxins can affect the liver, kidneys and nervous system and can be fatal, according to the commission, which said dog deaths tied to harmful algae have been documented in Massachusetts.
State health officials will keep monitoring the area. Two rounds of samples taken a week apart must fall below 70,000 cells per milliliter before the advisory can be lifted, the commission said.
