Excavation and Classification

  • Excavation and ClassificationExcavation activities for a remedial or recycling project should be based on technology timelines and technology requirements unless there is a possibility of the contaminant migrating to water table.
  • Excavations should be conducted in a way that moisture, contamination, and matrix are considered and calculated.
  • Excavation activities should include a gathering area where materials are blended and screened for maximum production rates at the remediation or recycling area.
  • Cross-contamination should be considered when transporting to the remediation and recycling area. Trucks moving materials from the contaminated area should not be the same trucks moving material from the excavation zone.
  • Ultimately the person in charge of excavation activities should be the same person performing the remediation.
