Hudson River plastic pollution – Detailed data from Riverkeeper Sweep 2018

Plastic pollution plagues the Hudson as it does the world over, and a new compilation of trash data from eight Riverkeeper Sweep locations gives a clearer picture of the problem.

The results are indicative of a culture of single-use: plastic bags, straws, Styrofoam coffee cups and takeout containers. The volume of these items entering our waterways is staggering. 

Our annual Riverkeeper Sweep brought out 2,300 volunteers on Saturday, May 5, 2018, for 120 cleanups and other projects to restore the shorelines and remove invasive species. Since 2016, we have worked with a handful of Sweep sites to gather comprehensive data based on the Ocean Conservancy’s Coastal Cleanup Data Card. During our first year of data collection, we teamed up with seven student and community groups to collect data at five sites.

Each year of our comprehensive data collection initiative, we have seen Styrofoam, cigarette butts, plastic beverage bottles, and single-use plastic bags in the top 5 most commonly found items. The rank varies by year, but these items consistently top our list, which is constant with data collected by The Ocean Conservancy.

Over seven years of Riverkeeper Sweep events, we have removed a total of 227 tons of debris from shorelines of the Hudson River, its tributaries and the New York City waterfront.

In 2018 alone, Riverkeeper Sweep volunteers cleaned up 38 tons of trash. A handful of project sites have been adopted as official unofficial parks by local residents and are maintained throughout the year. However, as Sweep continues to grow, the trash problem persists. We have not seen an overall decrease in the volume of trash we find.

Cleanups are an important component of the fight for a Trash Free Hudson, providing an opportunity to speak with our neighbors about our reverence of the Hudson River and its tributaries, remove as much trash as we can, and begin conversations about ways to prevent trash from entering our waterways in the first place. We hope you will be a part of it.

Here are ways you can help us work for a Trash Free Hudson:
