Public Health Warning Issued Related To Recent Sewage Discharge

Boston officials announced a public health warning on October 13, 2025, due to recent sewage discharges from a combined sewer overflow (CSO). This overflow happens when heavy rainfall exceeds the sewer system's capacity, leading to the mixing of rainwater and wastewater. Residents must avoid contact with affected water bodies for at least 48 hours after a discharge to minimize health risks associated with bacteria and pollutants. The public health warning complies with state regulations that mandate notifications for discharges lasting over two hours. Local health departments monitor these events closely to protect community health.

Residents can find further information and sign up for notifications through the Boston Water and Sewer Commission’s website. Additionally, alerts for sites around the Charles River are available via the MWRA. This proactive approach aims to enhance public safety during such environmental incidents.
