Measuring Pollutant Removal Efficiencies of Stormwater Treatment Units

This study evaluated the bacteria removal efficiency, and bacteria distribution and survivability within a structural best management practice (BMP) called Vortechs System (manufactured by Stormwater 360, formerly Vortechnics, Inc.) installed at two different sites in Providence, Rhode Island. Twelve rain events with precipitations greater than 0.1 inch were sampled over a two year period. Five pathogenic indicator bacteria, E. coli, Enterococci, Fecal Streptococci, Total Coliform, Fecal Coliform, were analyzed. Based on the author's research, maintenance strategies such as more frequent sediment removal may be necessary to prevent pathogen-rich washouts to receiving waters. Structural BMPs near busy streets and highways should be cleaned our more frequently.
