SWM ponds require routine sediment removal in order to maintain stormwater quality and quantity control. Sediments typically contain common urban contaminants (e.g. petroleum hydrocarbons (PHCs), polyaromatic hydrocarbons (PAHs), road salt, etc.) which trigger non-hazardous waste disposal requirements. Landfill tipping fees can amount to hundreds of thousands to millions of dollars per pond. This webinar presents two recent sediment beneficial use case studies. These studies demonstrate how ecotoxicity tests and risks assessments allowed the sediments to be used as topsoil amendments as cost effective and environmentally sustainable alternatives to landfill disposal. These studies set the precedent for future SWM pond sediment beneficial use projects as well.
