Students from the Fayerweather Street School are inviting residents to join them on a May 17 “Save Our Brook” march to the Alewife Brook.

Due to big storms overloading old sewer systems, 50 million gallons of sewage contamination were dumped in 2021 into the 2.5-mile brook leading to the Mystic River. There is too much pollution for the fish known as alewives to live in Alewife Brook, and they fled to spawn somewhere else, according to the students’ research.

There are groups trying to stop the pollution, and residents can help. “We need to tell our cities to finish separating sewer and stormwater lines and do what it takes to save the Alewife Brook,” students said

“We will march down to the Alewife Brook and spread the word,” said students in the third- and fourth-grade class of Nabia Meghelli, Katie Bruno, Aaron Bennett and Diana Tatz.

The march is at 8:30 a.m. May 17 starting at the Fayerweather Street School, 765 Concord Ave., in the Cambridge Highlands. The school is also having a bake sale; the proceeds will go to an organization that’s help to clean rivers, organizers said.
