Public Health Warning in effect until 3 PM, August 10, 2023
People and pets should avoid contact with the lower Charles River from August 8 – 10 due to the release of stormwater mixed with sewage into the river.
The release of mixed stormwater and sewage—known as a “combined sewer overflow (CSO)”—is needed to prevent contaminated water from backing up into homes, businesses and city streets.
State regulations require local public health departments to provide notice to the public when these discharges may create a risk to public health, including when a discharge lasts for more than two hours.
The CSO release occurred on August 8, 2023 between Magazine Park and the Boston University Bridge (MWR201 – Cottage Farm). It began at 11:56 a.m and ended at 3 p.m. This warning is in effect until 3 p.m.,Thursday, August 10, 2023.
The impacted areas of the Charles River may include the Cambridge and Boston sides of the river just upstream of the Boston University Bridge to the Mass. Ave. Bridge.
The public should avoid contact with impacted areas of the river for 48 hours from the time the overflow ends because of increased health risks due to bacteria or other pollutants carried by the stormwater, such as fertilizers or pesticides. Contact with this water can make you and your pets sick. Avoid paddle boarding, boating, fishing, or other activities that can bring you in close contact with this water.
Information about Cambridge CSO events are posted on the Cambridge Department of Public Works (www.cambridgema.gov/CSOReport) website. Additional information is available on the Massachusetts Water Resources Authority (https://bit.ly/MWRA-CSO-Notifications). Translations of the web pages are available using the translate box in the top right corner of the websites.
The City of Cambridge continues to make major improvements to the city’s sewer and stormwater systems. As a result, there are fewer CSO events than in the past, but they still occur after heavy rain. To learn more, please visit: www.cambridgema.gov/csoPlanning
The state law requiring public notification of sewage discharges into waterways took effect in 2022. Environmental groups advocated for the law because they were concerned that Massachusetts had no system in place to alert residents when sewage discharges occurred and what people could do to avoid illness. The new law requires municipalities to alert residents in multiple ways when discharges occur and to make the information available in other languages.
If you have questions about potential health risks from contaminated water, contact Sam Lipson at the Cambridge Public Health Department at [email protected] or 617-665-3838.
