The purpose of this research was to evaluate the effectiveness of four catch basins in the removal of stormwater contaminants for fifteen storm events in the District of Columbia. The four catch basins in this study are known as the: Hydrodynamic, Regular, Filter and Vortex catch basins. From the data that will be presented throughout this report it is our conclusion that the general order of performance in descending order were: Filter, Vortex, Hydrodynamic and Regular catch basin. The Regular catch basin produced more pollutants that it removed for 10 parameters. The Hydrodynamic produced more for 8 of the pollutants, while the Filter and Vortex produced negative values for 2 and 4 of the pollutants. In addition, the Regular catch basin collected some sediment, however it does not remove trash. All of the other catch basins regularly required trash removal before sampling. The Filter and Vortex show some potential for the removal of small particles with TSS removal of 80% and 76%, respectively.
