Groundwork Hudson Valley’s Great Saw Mill River Cleanup Kicks-off Earth Day

The annual Saw Mill River cleanup kicks-off Earth Day celebrations as in-person events return to Yonkers and greater Westchester County.


Yonkers, NY, April 8th, 2022 – The annual Great Saw Mill River Cleanup hosted by Groundwork Hudson Valley and The Saw Mill River Coalition returns to the City of Yonkers and other towns and villages throughout Westchester County on Saturday, April 23rd from 10am to 1pm. Every year, hundreds of volunteers gather to remove tons of trash and other pollutants from the Saw Mill River – home to the American Eel and many other species of plants and animals.

Groundwork’s Executive Director, Brigitte Griswold, said “The Great Saw Mill River Cleanup brings together communities across Westchester County for one single purpose – to help maintain and care for a river that unites them and is affected by the impacts of a changing climate and extreme weather patterns.”

The Saw Mill River is the only major tributary to the Hudson River in southern Westchester County, and when trash is thrown into the river, it goes through our communities and into the Hudson. Volunteers from all over Westchester County have the opportunity to make a great impact in their communities and on the health of the river by clearing it from trash and debris. This year, volunteers can choose from six sites in Yonkers, Irvington, Ardsley, Dobbs Ferry, and Hastings. Registration for the event is required and is currently open.

A wide array of local partners and sponsors are responsible for making this annual event possible. The Bonneville Foundation (BEF), Coors USA’s Change the Course Initiative, Cascade, Regency Centers, Westchester Community Foundation, Mom’s Organic Market, PS&S Engineering and Bartlett Tree Experts have signed on as early sponsors. For sponsorship information, contact Karen Tumelty at Groundwork Hudson Valley (

All public health protocols in place at the time of the Cleanup will be followed.
