An Evaluation of Pollutant Removal by a Demonstration Urban Stormwater Detention Pond
Construction of a demonstration urban stormwater detention pond in Greenville, NC in 1992 led to this study, the goal of which was to assess the effectiveness of the pond in removing urban runoff pollutants. Specific project objectives were:
• To perform a detailed analysis to quantify land use and other pertinent features of the detention pond drainage area.
• To quantify the inflow and outflow hydrology for the pond and to characterize the quality of runoff from its watershed.
• To perform settling column tests to measure the times required for maximum settling of runoff pollutants.
• To measure the stormwater detention pond removal efficiencies for total suspended solids, nitrogen, phosphorus, organic carbon and selected metals.
