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.
