Abstract
Data for a study in Portland, OR determining the occurrence of microplastics in stormwater catch basins and the potential effectiveness of stormwater biofilters in removing microplastics as described in a manuscript by Wolfand et al. (2023).
The README file provide details for the following data: (1) Results from grab samples taken from five catch basins during four storm events. Suspected microplastics were quantified visually with a microscope and confirmed with FTIR. (2) Results from a column study that was conducted to determine the removal of microplastics by three types of geomedia: a proprietary mix, the City of Portland standard mix, and layered compost and sand. Each geomedia was tested in triplicate for five tests.
