Get dirty for cleaner rivers!

Plan Your Cleanup

Thanks to all who participated in this year’s cleanup!

The 2023 Source to Sea Cleanup has now concluded. Thank you so much to the 130+ groups who participated! Your dedication to keeping our rivers clean is making a huge positive impact. You are welcome to see some of our early highlights and be on the lookout for the new Cleanup Chronicle which will provide many more stories, photos, and trash stats. We’ll be back with the 28th annual cleanup in 2024.

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.

How To Get Involved

Year-Round Cleanups

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


Fall Cleanups

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:

  1. Sign up with a group you know or find a group accepting volunteers
  2. Clean up!
  3. 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.
