Great Massachusetts Cleanup

27th Annual Earth Day Charles River Cleanup

Friday, April 24, 2026Saturday, April 25, 2026
Newton, Weston, Wellesley, Dedham, and more locations west through the Upper Charles River Watershed.

Working with our partners at the Emerald Necklace Conservancy, Charles River Conservancy, Waltham Land Trust, and Esplanade Association, we collect trash from the Charles River and surrounding area with thousands of incredible volunteers. The Earth Day Charles River Cleanup builds on a national effort as part of American Rivers’ National River Cleanup®, which has removed over 25 million pounds of trash from America’s waterways. Our cleanup brings together over 3,000 volunteers each year to pick up litter, remove invasive species, and assist with park maintenance along all 80 miles of the Charles River.

Individuals, families, and small community groups will volunteer on Saturday, April 25th. We recommend registering early to secure your spot. Please let us know of any members of your group that you will be participating with to be assigned to the same site.
