Microplastics data collected from streams in the northeastern United States, 2017-2018 These data were collected to characterize the quantity and quality of microplastic particles found in 17 streams in the northeastern United States, from New York to Virginia. USGS staff who represent the Urban Landscapes Capabilities Team (ULCT) within the North Atlantic-Appalachian Region designed the study and collected the water samples on which the data are based. Data were collected during 2017 and 2018 and included a baseflow and stormflow sample at each site. Additionally, the various microplastic particles in each sample were characterized by one of two different size-fraction categories (categories of 355-1000 micrometers and 1000-5600 micrometers), by type of particle (fiber/line, fiber clump, bead/pellet,...

Daily streamflow was estimated for all the nontidal parts of the Chesapeake Bay watershed with the program "Unit Flows in Networks of Channels" (UFINCH; Holtschlag, 2016), together with the observations of measured streamflow at gages at the downstream ends of major rivers. The estimated streamflow was aggregated at the HUC12 level and reformatted as an Optimal Hydrograph Separation (OHS) input file...
