Abstract

Storm runoff pollutants are among the major sources of surface water impairments in the U.S. However, there are several guidance on stormwater best management practices and pollution prevention plans, but there are many streams still impaired by the urban runoff. The first chapter of this thesis investigates the influence of microplastics (MPs) weathering on their heavy metal uptake in stormwater. The results underscored the critical role of MPs in transporting the heavy metal contaminants from urban environment to the water resources. The second chapter evaluates the self-reported stormwater quality data collected during 2014-2018 for an industry sector involving twelve facilities in West Tennessee. The results demonstrated both organic and inorganic release to the stormwater at studied industrial facilities. This thesis results could prompt more informed decisions by policy makers and monitoring agencies to control the plastics and other contaminant release to the stormwater.
