Locations from Brooklyn to the Adirondacks

Thanks to our Sweep Leaders, volunteers, partners, and sponsors, our 10th Riverkeeper Sweep was our biggest yet! On Saturday, May 1, over 2,600 volunteers came together to cleanup 29 tons of debris. For a comprehensive overview of our 10th Sweep, read our blog post, 10th Annual Riverkeeper Sweep – Our Biggest Yet. To take a deep dive into our Sweep data and comprehensive data collection project in our other recent blog, http://What’s in our river? Sweep volunteers examine Hudson River plastic pollution.

Also, please save Saturday, May 7, 2022 for the 11th Riverkeeper Sweep! Check back later this year for more information about next year’s volunteer and sponsorship opportunities.


We welcome you to participate in the 10th Annual Riverkeeper Sweep, our annual day of service for the Hudson River and its tributaries by joining a shoreline cleanup or tree planting project at a location near you. Over the last nine years, Riverkeeper volunteers have completed 804 projects along hundreds of miles of shoreline during our annual day of service for the Hudson, where volunteers have removed 275 tons of debris, and planted or maintained 4,490 trees or native grasses.

Join us at one of 125 project sites along the Hudson River and tributaries for cleanups, invasive species removal, and planting projects. Find a project near you and register to participate (full list below!). Pre-registration is required to participate. Is there a location in your community in need of cleanup, removal of invasive plants, or another type of restoration project that’s not on the map below? Submit the Prospective Community Cleanup Locations SurveyIf you are interested in sponsoring the 2021 Riverkeeper Sweep, please e-mail Jen Benson at [email protected] for more information.

Due to the on-going COVID-19 pandemic, we’re making changes this year to ensure safety for all participants. Event capacity is smaller and social distancing is absolutely necessary. Please observe the following social distancing requirements:

    • Pre-registration is required to participate.
    • All participants must bring their own masks, gloves, hand sanitizer, and reusable water bottles.
    • All volunteers must maintain a minimum distance of 6 feet and wear masks that fully cover nose and mouth at all times – no exceptions.
    • When announcements are being made, a distance of 15 feet should be maintained.
    • Volunteers should carpool only with members of their own household.
    • Volunteers should not participate if they have ANY signs of illness or if they have potentially been exposed to COVID-19 within the previous two weeks.

Riverkeeper Sweep Brewery Partnership

Riverkeeper Sweep is proud to partner with dozens of breweries around New York City and the Hudson Valley. In the past, our brewery partners have generously donated a free beverage for each 21+ volunteer at one of three dozen participating breweries and bars. The COVID-19 pandemic has posed unique challenges for our partners, and we would like to support them.
