Abstract:
The effectiveness of a short-circuiting stormwater pond draining a residential neighborhood was determined for total suspended solids (TSS), total phosphorus (TP), and soluble phosphorus (SP) were determined and the major pollutant sources in the watershed predicted. The study included nine storm events and the mean pollutant load removals in the pond were 80% for TSS, 69% for TP, and 60% for SP. The source loading andmanagement model (SLAMM) predicted streets and driveways as the major sources of TSS and TP contributing 75% and 57% respectively even tough they constitute 9% of the total area of the watershed. Landscaped areas were the biggest source of SP. The detention pond control in SLAMM predicted removal rates of 79% for TSS and 62% for TP for the pond. SLAMM predicted TSS and TP removal rates will increase 10 and 8% respectively if the full surface area of the pond were involved in pollutant treatment. The results highlight the importance of surface area in the treatment of stormwater runoff and the need to identify critical source generation areas in a watershed and target management practices at those sources.
