Title

Treatment Efficiencies For Residential Stormwater Runoff In A Hardwood Wetland

Abstract

The fate of nutrients and heavy metals contained in storm-water runoff was investigated in a 3 ha hardwood wetland near Orlando, Fla. The wetland receives stormwater runoff from a large residential community through a small shallow canal and provides treatment prior to discharge to Hidden Lake. Field investigations begun in 1984 were divided into the following tasks: (1) assessing the quantity of nutrients and heavy metals entering the wetland by stormwater runoff, (2) attenuation of the pollutants during travel through the wetland, (3) monitoring movement of nutrients and heavy metals in ground water, and (4) accumulation of nutrients and heavy metals in the sediments of the wetland. During continuous flow, the wetland system was found to be very effective in removing heavy metals but less effective in removing nutrients. Heavy metals appear to be tightly bound into the upper sediment layers. Treatment of runoff by infiltration through wetland soils resulted in good removal of nutrients as well as heavy metals. The results suggest that treatment schemes involving infiltration or retention are possible and more effective than flow-through systems. © 1986 Taylor and Francis Group, LLC.
