Abstract

Trash is a pervasive form of pollution in aquatic ecosystems. A lot of work has been done on trash in the ocean, but less work on trash in streams and rivers and how they contribute to this worldwide problem. This work is focused on trash in urban stream ecosystems, where it is, and how it moves. Mark-recapture trash surveys were performed in Potash Brook, an urban stream in South Burlington, Vermont. In four reaches, data on the location of the trash and its properties were recorded along 30 m transects. Repeat surveys were conducted on at least 4 subsequent dates during summer and fall 2024, and 5 dates in 2025. The trash was only removed during the last fall sampling date each year. Residence times were calculated as days between the surveys when the trash was first seen and when it was no longer found.
