Stormwater Management Pond Sediment – Valuable Resource or Costly Waste

Watch Here

Stormwater management (SWM) ponds play a crucial role in flood control and water quality treatment across Canada and the United States. Over time, these ponds accumulate sediment containing soil particles and urban contaminants. Municipalities and private owners often face high costs for sediment disposal, compounded by dwindling landfill space and increased environmental concerns. This session explores a 17-year study analyzing sediment from 121 SWM ponds to assess contaminant sources, leachability, and ecotoxicity. Attendees will gain insight into sediment characterization, contamination risks, and sustainable management practices.
