Restoration Roadmap
Collection → separation → resource reuse → ecosystem restoration
From pollution-source removal to restoration,
one integrated process.
Ecosystem restoration is more than removing contaminated sediment. It is an integrated process connecting collection, separation, stabilization, resource recovery and riverbed restoration.
Soil Resources safely collects contaminated sediment, controls pollutant spread through separation and stabilization, and reuses recovered aggregate as restoration material in a circular restoration system.
Ecosystem Restoration Roadmap
After contaminated sediment is collected, useful aggregate is separated from contaminated fines, which are stabilized. Recovered aggregate is then reused for riverbed restoration and Capping to create the foundation for aquatic recovery.
Safely remove bottom-layer pollution by dredging
Separate gravel, sand and sludge to reduce contaminated fines
Reduce heavy-metal leaching and dispersion
Reuse washed aggregate for restoration
Create habitat through Capping and reapplication
Improve water quality and rebuild aquatic habitat
Remove nutrient-rich contaminated sludge to reduce odor, algal blooms and turbidity.
Manage turbidity and contaminant spread during collection, transfer and treatment.
Use recovered aggregate and improved soil to create a stable base for aquatic life.
A restoration approach that reduces disposal and increases on-site reuse.
Technology and restoration must work together
to bring waterways back to life.
Contaminated-sediment treatment is the starting point for restoration. Water-quality and habitat recovery become more effective when source removal is followed by clean-aggregate reapplication, Capping, waterfront improvement and ongoing management.
- Direct Benefit Pollutant removal and containment
- Ecological Benefit Return of aquatic life and natural resilience
- Community Benefit Improved waterfront spaces for communities
