Toxic Element Analyses of Summer and Winter Storm-Water Sediment by Neutron Activation Analyses

To maintain the effectiveness of a storm-water detention/retention pond, the sediments accumulating at the bottom the pond must be periodically removed and treated for ultimate disposal. The required pond clean-outs may be executed during the winter months to minimize the impact on the pond’s operation and the recreational use of surrounding areas. However, the difference in trace element concentrations of storm-water sediments between the …
