Riverkeeper Sweep campaign
Cleaning up shorelines along the Hudson River and its tributaries
The challenge
Trash that ends up in our rivers, creeks, and streams — also known as marine debris — is a big problem. In addition to disrupting the beauty of our waterways, litter directly impacts water quality and, by extension, the wildlife that lives there. Trash can also contain materials hazardous to both humans and animals.
Trash enters the Hudson River and its tributaries from a variety of sources, including storm drains, illegal dumping, and general littering. The majority of the trash found in and around the Hudson is plastic. Plastic is particularly problematic since it doesn't biodegrade, and instead often breaks down into tiny pieces known as microplastics that are nearly impossible to clean up. These microplastics absorb toxic chemicals that pose a threat for the hundreds of species that have been found to consume them.
In order to protect our wildlife, as well as the waters where we enjoy recreating, Riverkeeper is committed to making and keeping the Hudson and its tributaries free of trash.

What we're doing
Thousands of you make a lasting difference throughout the year.
Cleaning up our shores
Since 2012, Riverkeeper has set out to protect our waterways from the harms of trash. During our annual Riverkeeper Sweep, we work with thousands of volunteers from New York City to the Adirondacks to collect trash, plant native species, and restore shorelines at dozens of sites on the Hudson and its tributaries.
Sweep is one of our most popular events, offering a fun, memorable opportunity for residents of all ages to connect with the river and make a meaningful impact in their community. To increase our impact, we have made Sweep a year-round program!
Seeing firsthand all of the amazing and hard work that goes into organizing the Riverkeeper Sweep is both humbling and empowering. The staff are extremely knowledgeable and supportive, encouraging involvement from volunteers throughout the Hudson Valley. You meet others who are interested in educating themselves and taking the necessary steps toward making positive changes.

Sweep as ecological restoration
Sweep’s focus includes restoring the ecological health of our waterways, an effort that includes the maintenance and planting of trees, shrubs, and flowers, as well as removal of invasive species.
Riverkeeper and our partners have planted and maintained thousands of trees and plant species as well as removed thousands of invasive plant species from the Hudson and its tributaries.
As more trash is removed from the shoreline and other natural spaces, there is more light and space for native plantlife to flourish. Not only does this contribute to a healthier ecosystem, but it also helps protect the surrounding landscape from flooding during heavy rainstorms.

Protection through legislation
With your action and advocacy, Riverkeeper has helped pass legislation to stop trash at the source. This includes bills reducing the volume of single-use plastic and micro-debris in the environment, such as the 2015 Federal Microbeads Free Waters Act, the 2019 New York City bill restricting the sale or use of certain polystyrene items, and the 2020 New York State Bag Waste Reduction Law.
These bills provide the legal muscle to support our clean up efforts and help us mitigate the spread of trash throughout the Hudson River watershed.
