Ex-situ (Off-Site) Decontamination: A Methodical Approach

The ex-situ method, involving the excavation of contaminated soil, is a meticulous approach that we execute with precision:

Emergency Responsiveness: Ex-situ decontamination ensures a swift response in case of spills, accidental leaks, or any urgent incidents requiring immediate intervention.

Adaptability to Dismantling: When dismantling petroleum equipment, buildings, or other structures, ex-situ decontamination often proves to be the preferable method.

Time Management: The ex-situ method is advantageous when time is crucial, facilitating prompt planning and execution.

Soil Conditions or Contaminant Nature: When soil conditions or the nature of contaminants do not allow for in-situ treatment, ex-situ decontamination provides an effective solution.

Precise Analysis: Ex-situ decontamination involves excavation followed by rigorous soil analysis, ensuring disposal in compliance with environmental standards.

Environmental Control: Opting for ex-situ decontamination allows for tight control over the management of contaminated soils, from excavation to disposal at a certified treatment site.

Risk Reduction: Ex-situ decontamination minimizes the risk of contamination spreading, providing a safer solution in certain contexts.

Flexibility of Site Use: Following ex-situ decontamination, the remaining soil on-site undergoes analysis to ensure it meets the required environmental quality for future site use.

The ex-situ decontamination process starts with the excavation of the contaminated area. A temporary pile is created to separate the “clean” soil from the contaminated soil, with the latter then transported to a certified treatment site. The soil left on-site undergoes analysis to ensure it meets environmental quality standards suitable for the intended use of the site.
