Toxic bacteria outbreak strikes before the Head of the Charles

A toxic cyanobacteria outbreak threatens the Head of the Charles Regatta, scheduled for October 17-19 in Boston and Cambridge. The Massachusetts Department of Public Health reported harmful water conditions downstream of the Cambridge Street/River Street bridge as of October 6. According to Stefan Geller of the Charles River Watershed Association, climate change has led to more frequent and long-lasting cyanobacteria blooms in the river. State officials warn that contact with the contaminated water can cause skin rashes and eye irritation, urging the public to avoid water contact, stating, "WHEN IN DOUBT, STAY OUT! " Despite these risks, organizers plan to proceed with the regatta, hoping that cooler temperatures will help dissipate the blooms.

They are working closely with state officials to monitor the water conditions and ensure safety for participants and spectators. The event is expected to attract around 12,000 rowers and thousands of spectators along the Charles River. This incident underscores the ongoing challenges posed by climate change to local waterways and public health.
