This story focuses on a volunteer event organized by the Anacostia Watershed Society. Participants categorize, count, weigh, record information on, and dispose of trash that was collected from the Nash Run Trash Trap located in the Kenilworth neighborhood of D.C. The trap is located in a tributary that feeds the Anacostia River. Data collected from events like these help the organization advocate for policy changes in the District, such as the D.C. Bottle Bill.
