Contaminated soil disposal connects the material being excavated to representative investigation evidence. We arrange removal based on the source, composition and receiving requirements. Results from another stockpile or depth should not be assumed to describe soil simply because it comes from the same site.

Classification and landfill acceptance
Waste classification and landfill acceptance testing answer different questions about excavated material.
Stockpiles and unexpected findings
Keeping stockpiles linked to their samples helps prevent assessed and unassessed soils becoming mixed.
Classification and landfill acceptance
WM3 classification establishes the waste description and hazardous properties. Waste acceptance criteria testing, where required for landfill, answers a different question about acceptance at a landfill category. WAC results do not replace the classification assessment, and neither assessment should be separated from the actual material being loaded.

Stockpiles and unexpected findings
Separate stockpiles and sampling references help preserve that link during excavation. Suspected asbestos, visible waste or free liquid needs explicit consideration before loading. We confirm an authorised receiving destination and explain any further assessment required, so a collection does not rely on the appearance of clean-looking soil.
Material changes during excavation
Unexpected staining, odour or buried debris can mean the next excavation area differs from the sampled stockpile. We keep that change visible rather than continue using an earlier description without review. The receiving site’s acceptance needs to cover the soil actually loaded. This also helps separate material suitable for an agreed route from stock awaiting further classification or testing.
Contaminated Soil Disposal: common questions
Does clean-looking soil count as inert waste?
Appearance does not establish an inert classification. Source and representative composition evidence are needed.
Is a WAC test the same as hazardous waste classification?
Classification identifies the waste and its hazards. WAC testing concerns landfill acceptance and does not replace classification.
Can soil containing suspected asbestos be loaded normally?
Suspected asbestos must be considered explicitly before handling and acceptance are agreed; routine loading cannot simply be assumed.
Can soil colour prove it is non-hazardous?
No. Classification follows composition and representative evidence, not appearance.
Does every stockpile need identical testing?
The investigation and receiving criteria determine the evidence needed; one result should not be assumed representative of different materials.
