Ex-Situ: Removal and Disposal

Thursday, August 12, 2010 by August Mack Environmental, Inc.

The Ex-Situ removal and disposal cleanup technology results in the following:

  • Contaminated soils are removed by physical excavation from the ground
  • Source area of contamination is eliminated
  • Soils need to be profiled through an appropriate landfill
  • Removal technique requires extensive pre-planning and scheduling
  • Confirmatory soil samples are collected around the excavation to confirm effectiveness
The advantages of the ex-situ removal and disposal method are the following:
  • It is effective on all soil types
  • It is an agency accepted cleanup method
  • The timeframe for cleanup is short
  • It removes potential contributors to groundwater impacts
The disadvantages of ex-situ removal and disposal are the following:
  • Must understand full extent of impacts
  • Disruptive to site operations
  • Depth limitations
  • Challenging with shallow groundwater present
  • Impacts may have to remain under structures and utilities and along property boundaries
