Electronic Theses and Dissertations
Georgia Department of Transportation (GDOT) has constructed various treatment facilities on its right-of-way (ROW) to collect and treat highway stormwater runoff, emphasizing total suspended solids (TSS) removal. The permit performance goal set by the Georgia Environmental Protection Division (EPD) is 80% TSS removal. Current stormwater best management practice (BMP) treatment facilities include complex and permanent infrastructures such as bioslope, bioretention basins, sand filters, infiltration trenches, and grass channels. Among these BMPs, bioslope has been becoming more popular due to its applicability for roadway embankments and areas with limited ROW constraints. It removes pollutants effectively by physical filtration and chemical adsorption …
