Welcome to the Source to Sea Cleanup, a powerful and effective community event spanning the length of our 410-mile watershed in NH, VT, MA, & CT. Each fall, thousands of volunteers of all ages and abilities come together to do their part and spend a few hours making the water cleaner, the river banks safer, and the wildlife happier.
Although our annual event runs each fall, we encourage folks to consider cleaning up rivers, streams, parks, and city streats at other times of year, such as hosting an Earth Day Cleanup in spring, when foliage is still low and poison ivy at bay!
Cautions to spring cleanups: cold, high, and fast-moving water
Lead a Group
Group Leaders organize the details of their own group(s) throughout the watershed. Start planning your group here.
Join a Group
If you’re most excited about cleaning, but less interested in organizing, you can join us as a Group Volunteer:
- Sign up with a group you know or find a group accepting volunteers
- Clean up!
- Tally the trash you collect to help CRC keep track of what’s out there. We use this data to advocate for pollution solutions.
Go out on your own
You may register as a Solo Volunteer! This helps us know that you’re out there & where you’re planning to clean. After your Cleanup, please share your Trash Tally with us.
