SITE DESCRIPTION
Treated Volume | 340 m³ of contaminated soil |
Thermal technology | In-Situ Treatment |
Main contaminant | PCE/TCE, DNAPL, LNAPL |
| Site challenges | Treatment performed directly beneath a high-voltage transformer |
Project Timeline | 2016 |
SOLUTION
Treatment Method |
In-Situ treatment of a 36 m² area, Installation of 15 heating tubes and 24 steam tubes connected to an EVS system |
Treatment program | Target temperature 88°C for 42 days |
Contaminated Vapors Management | Non-condensable gases were thermally destroyed to meet discharge standards, while condensable vapors were collected in a tank and transferred to the GEO facility for treatment. |
Process control | Continuous temperature monitoring into the soil throughout the treatment |
RESULTS
✅ No VOCV residues detected in the soil after treatment |
✅ Successfully treated 288 m³ (524 tonnes) of contaminated soil |
✅ Cleanup objectives for chlorinated solvents achieved |
