Charles River Conservancy

The Conservancy is thrilled to be able to offer small, in-person cleanups to celebrate Earth Day 2021. During the week of April 19th – 24th, participants will remove trash and debris from an assigned section of the Charles River Basin.  We hope you will join us for a safe and fun way to get outside and give back to the parks that have given us so much! We are so thrilled at the response to participate in the 22nd Annual Charles River Earth Day Cleanup!

We still have spots available for groups to participate on Monday (4/19), Tuesday (4/20), and Wednesday (4/21) and space for individuals and families at our Wednesday (4/21) and Saturday (4/24) events!

Charles River Watershed Association

We hope you will join us for this year's Annual Earth Day Charles River Cleanup with a virtual twist!

Registration for Individuals, Families, and Small Groups

Individuals, families, and small groups are encouraged to participate in this year’s Charles River Cleanup. We ask volunteers to clean 2 to 3 blocks within their home address, or at their local river access location. Feel free to participate at your leisure - though you may want to conduct your cleanup prior to your trash day as volunteers are responsible for disposing of the trash they collect. Individual volunteers are gently suggested to donate $5 to support CRWA. 

Register as an individual, family or small group with the CRWA here.

Registration for Large Groups and Corporations

Each group can register for a three-hour time slot during the week. Group sizes will range from 10 people to 25 people, depending on the assigned cleanup location. We can accommodate groups larger than 25: we will split your group into teams, and assign several locations or time slots, depending on your organization's preferences. 

Register for a large group or corporation with the CRWA here.
