Her obJective <br /> was to determine how well the Vortechsm System retained pollutants fi�om parking lot runoff, <br /> including total suspended solids (TSS), nutrients, metals, and petroleum hydrocarbons. <br /> A Vortechs° Model 5000 was installed in 1998 to treat runoff from the 82-space parkir.g lot of <br /> Timothy Edwards Middle School. The entire watershed was approximately 2-scres (G.81 ha), and <br /> was 80% impervious. <br /> Testin Period Jul 2000 to A ril 2001 <br /> # of Storms Sam led weekly composite samples taken <br /> Mean Influent 324 mg/L <br /> Concentretlon <br /> Mean Effluent 73 mg/L <br /> Concentretion <br /> Removal Efficienc 77% <br /> Additionally, the Vortechsm System was particularly effective in removing zinc (85%), lead (46%), <br /> copper (56%), phosphorus (67%) and nitrate (54%). <br /> The study concluded that the Vortechsm Stormwater Treatment System significan[ly reduced <br /> efFluent concentretlons of many pollutants in stormwater runoff. <br /> Rev 4-29-U4 (WSG? <br />
