Volunteer Engagement Fees

One of the largest river cleanups in the country, the Charles River Cleanup draws more than 4,500 volunteers. This complex event requires materials and coordination from the Cleanup’s program partners – all nonprofit organizations working to improve water and greenspace quality in the greater Boston area. Because of this, we ask our corporate and for-profit volunteer groups to support our management of this great event with a tax-deductible donation to the organization hosting your work site. This donation is mandatory and is based on the size of your group. Similarly, we ask that individuals and non-profit participants consider supporting the event with an optional donation. All donations are fully tax-deductible and support the Charles River Cleanup and the missions of our partner organizations. Thank you!

Individuals and Community Groups

Thousands of friends, families and Charles River neighbors roll up their sleeves every year to make the Charles River Cleanup a success! Individuals are encouraged to participate alone or with friends and family. We suggest a donation of $10 per person to cover the cost of materials and coordination. All donations to the event are fully tax-deductible
