Thermal Remediation of Diesel-Impacted Soils Beneath Existing Infrastructure

Approximately 247 m³ of diesel-contaminated soils were treated using In-Situ Thermal Desorption, achieving remediation targets to a depth of 7 m and supporting the redevelopment of the site into a parking facility.

SITE DESCRIPTION

       Treated Volume

247 m³ of contaminated soil

          Thermal technology

   In-Situ Treatment 

       Main contaminant

Hydrocarbons

        Site challenges

  Contamination located beneath & adjacent to a building

        Project Timeline

2016 



SOLUTION

          Treatment Method

  In-Situ Thermal Desorption

          Treatment program

Excavation of a 9.7 m × 6.6 m pit to a depth of 3 m, Installation of 6 Smart Burners and 12 steam tubes

         Contaminated Vapors                          Management

Reburn

       Process control

Performance was verified through post-treatment soil sampling conducted both inside the building and within the excavated treatment area. 


RESULTS

✅          Successfully treated 247 m³ (445 tonnes) of contaminated                    soil

✅          Treatment objectives achieved throughout the excavated area

✅         Site prepared for future parking lot development
