Abstract

Abstract: Agricultural runoff is non-point source pollution that is unpredictable and difficult to control. Best Management Practices (BMPs) and Low Impact Development (LID) has been utilized as a method to manage agricultural runoff. Treatment train systems are LID-BMPs arranged in a series that aims to treat and manage agricultural runoff. This study focuses on the use of treatment train systems to reduce the concentration of BOD in agricultural runoff. A treatment train system was set up with three varying configurations to evaluate the efficiency of BOD removal. The three configurations consisted of no vegetation set which acts as the control, vegetated set, and vegetated set with the saturated zone. All three configurations showed good final removal rates of BOD at 56% for the control and 75% and 85% for both vegetated sets without and with the saturated zone. The control is classified classifying it as Class III according to Water Quality Standards, while both vegetated set without and with saturated zone had classified both sets as Class II and I, respectively. The performance of the treatment train system was compared to the use of a single bioretention system.
