Source to Sea Cleanup

Welcome to the Source to Sea Cleanup, a powerful and effective community event spanning the length of the 410-mile Connecticut River 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.

Volunteers will be able to join cleanup groups starting August 5th!

The 28th Annual Source to Sea Cleanup is Coming Up Soon!

Get your gloves and trash bags ready, the goal of the Source to Sea Cleanup is to remove as much trash as possible from our waterways, riverbanks, and communities. Trash moves from land to water, from upstream to downstream, and together we can make a BIG impact in preventing this trash from ending up in our rivers. 

The Source to Sea Cleanup will be on September 27-28th, 2024 (or a date that works for you!)

Overview of the Cleanup
Getting Dirty for Cleaner Rivers

What began as a group of volunteers organizing to remove trash from local rivers over two decades ago has become a hugely popular annual event that brings communities together in support of clean water and healthy habitats throughout the Connecticut River watershed - in New Hampshire, Vermont, Massachusetts, and Connecticut.


Volunteers are organized into groups with Group Leaders coordinating details at different trash sites (Group Leader registration is now open!). Trash tallies are also gathered after each cleanup, contributing to Connecticut River Conservancy's long-standing database which is used to inform our work in advocacy to reduce future pollution, support river restoration, and inform the public and policy-makers of issues affecting the environment.

Trash tally results throughout the 4-state watershed show that in 2023 132 groups consisting of over 1,251 volunteers collected over 34 tons of trash - and there'll be more this year! See our Cleanup Chronicle for more details.

While the Source to Sea Cleanup is all about picking up trash in our waterways, streets, and parks – it is also part of a greater effort that includes recycling our waste, speaking up for legislative actions to reduce pollution, and advocating for producers to develop products that are less harmful for the environment.


We are pleased to see that after years of advocacy by Connecticut River Conservancy and partners, a Tire EPR (Extended Producer Responsibility) bill has passed in Connecticut, becoming the first of its kind in the nation. This new legislation will decrease illegal tire dumping, save municipalities money, and boost tire recycling.


On the flip side, legislation does not always go as we hope, as in the case of Vermont’s bottle bill – which would add containers like water bottles, juice bottles, and wine bottles to the list of redeemables – getting vetoed in 2023. Our River Stewards regularly comment on permits and legislation to steer policy in a more river-friendly direction, and we encourage you to sign up to our state-based eblasts at to get river updates and action opportunities in your state.

Speak Up For Cleaner Rivers

All it takes is a series of small actions by lots of people to make a big impact on our rivers. Through personal power and responsibility, we can keep our rivers clean for all to enjoy.

Wondering how you can make a difference? Start with a few small steps:

Multiply your impact — Invite friends, family, and co-workers to join you in this effort.

Speak up for your rivers — Contact your elected representatives, show them the trash problem and let them know this is an issue that is important to you and deserves their attention and legislative action.

Use the power of your purchase — Tell businesses what products to make and sell; purchase only reusable items and refuse single-use plastic and foam.

Lead by example — Don’t litter and properly dispose of your waste — no wish-cycling!

Get involved when there's a bill —  Sign up for CRC's state-specific advocacy emails which include action alerts for when there is legislation you can directly support (or oppose!).
