Contaminated Soil Removal

We establish survey control and excavation grids, verify utility locates, install erosion and sediment controls, and prepare a stable loading area before disturbing impacted ground. Excavators remove soil in controlled lifts and cells while a spotter and the environmental consultant monitor visual, odour, and field-screening indicators. Separate buckets and haul paths prevent cross-contamination.

The governing documents are O. Reg. 406/19, the Excess Soil Rules, O. Reg. 153/04 when a Record of Site Condition applies, O. Reg. 347 for soil managed as waste, and the remedial action plan. Together they control characterization, storage, tracking, transport, destination acceptance, confirmation sampling, and site-specific release decisions.

The price responds to the contaminant profile, excavation depth, groundwater, shoring needs, soil volume and density, trucking distance, receiving-site fees, analytical turnaround, site access, and backfill requirements. Rain and groundwater can mobilize contaminants and interrupt sampling. Berms, covers, clean-water diversion, sump control, and planned dewatering keep the excavation manageable and the record defensible.

The controlling schedule factors are laboratory turnaround, receiving-site capacity, haul distance, excavation support, water management, and the Qualified Person's confirmation sampling release. Approved trucks are loaded to legal weights, tarped, documented, and dispatched only to the destination identified for that soil quality. We reconcile tickets, scale weights, and excavation quantities each shift.

Yes. We phase cells, isolate haul routes, use controlled loading windows, and maintain access for plant, tenant, or municipal operations while protecting clean areas from truck traffic and tracked soil. Rain and groundwater can mobilize contaminants and interrupt sampling. Berms, covers, clean-water diversion, sump control, and planned dewatering keep the excavation manageable and the record defensible.

Quality records include survey quantities, daily truck logs, scale tickets, destination receipts, stockpile IDs, field observations, and confirmation sampling results. The environmental consultant and Qualified Person make environmental release decisions, while Harrowgate maintains traceability between each excavation cell, temporary stockpile, transported load, receiving site, and placed backfill area.

Provide environmental reports, soil analytical tables, a remedial action plan, civil and shoring drawings, utility information, estimated quantities, proposed destinations, site access limits, and the target excavation and backfill schedule. We establish survey control and excavation grids, verify utility locates, install erosion and sediment controls, and prepare a stable loading area before disturbing impacted ground.
