Exploring the Use of Eleocharis Palustris and Phyleum pratense to Filter Out Cu and Pb in Stormwater Runoff Entering the Laramie River, Wyoming


Pollutants rrom urban stormwater are a tureat to tne water quality or tne receiving waters (Fulcher, 1994). In many places vegetation has been used to filter out contaminants from sewage treatment plants, mine effluent and agricultural effluent Native and non-native species of vegetation can also be used to help filter out heavy metal contaminants entering the fluvial environment through storm sewer outflows (Ellis, J.B. et al. 1994 and Startin, 1994). The objectives of this study are (1) to determine the dominant native and non-native herbaceous riparian species growing in storm water gullies which discharge into the Laramie River (2) to compare the uptake of Cu (Copper) and Pb (Lead) between two species in a greenhouse experiment (3) compare how the metals are partitioned between roots and shoots (4) to determine if the two species are suitable for revegetation of disturbed areas within the storm sewer gullies. The study area consisted of two stormwater outflow gullies which discharge into the Laramie River at Laramie, Wyoming. The greenhouse experiment was conducted at the University of Wyoming Plant Soil and Insect Sciences 30th Street Greenhouse in Laramie.
