Ocean Conservancy, through its International Coastal Cleanup program, coordinated a volunteer effort to clean the Anacostia River in Washington, D.C., on September 26 and 27, 2026.
Participants removed litter from the river and gathered data for researchers, aiming to keep trash from entering the ocean and to generate information that can support environmental policy advocacy.
The International Coastal Cleanup initiative regularly arranges similar local events to address marine debris and to inform policy decisions.
