Abstract

Litter, whether river-based, marine, or terrestrial, is an ever-increasing environmental and economic issue. However, litter in freshwater environments is studied less than in marine environments. To better understand factors impacting stream-transported floating litter, seven watershed characteristics were assessed across a network of thirty litter collection devices. The research objective for this study was to quantify litter loading and assess watershed characteristics relative to litter loading. Of the various watershed characteristics in this study, land cover classification had the greatest impact on the amount of litter collected from the Litter Gitters followed by median household income. Results from this study can strengthen litter collection device placement and best management practices for litter prevention.
