The most straight-forward method of soil remediation is to remove contaminated soils from the site. This approach is often recommended when the volume of impacted soil is relatively small or when contamination is only present within near-surface soils.

The steps associated with soil removal include:
Testing the soil for landfill approval
Staking out the removal area
Identifying and marking on-site utilities
Excavating the contaminated soil
Loading the soil into a dump truck
Collecting confirmation soil samples from the excavations
Sending the samples to a laboratory for analysis
Evaluating the sample results to approve backfilling the excavation
If any confirmation soil sample exceeds the cleanup objectives, then additional soil removal and additional confirmation soil testing is required.
