Evaluation of Media Effectiveness for Phosphorus Removal at the Rosland Park Filtration System

Abstract

unique surface water filtration system at Rosland Park (referred to as the “Rosland Park Filtration System” or “Filtration System”) as a Best Management Practice (BMP) to manage phosphorus loading to Lake Cornelia. The filter consists of four filter vaults (or “cells”) through which urban-impacted runoff and stormwater is pumped. Construction of the Filtration System was completed in July 2022 and the performance monitoring program began in August 2022. This report summarizes the results of the monitoring program. Because of the unique design of the Filtration System, the initial performance monitoring program was intended to be intensive to provide information for future improvements to the system and to provide valuable lessons-learned to the stormwater and watershed management community.
