Project:

Hydrocarbon leak in steppe environment

Action:
Soil and groundwater remediation.

Location:
Argentina

Customer:
Confidential

Methods
High vacuum in double phase

Products:
Gasoil y diesel.
TPH, LNAPL

Background information

Estimated loss of 2000 m3 of hydrocarbon in a poly-pipeline in the Argentine steppe zone affects the quality of the subsoil, reaching the groundwater at a depth of 12 m, in three sectors of 20, 4 and 1 ha.

Objective and limitations

Free phase elimination hydrocarbon y reinfiltration of extracted groundwater given the steppe and isolated environment.

Methodology applied

High vacuum two-stage extraction and reinfiltration

Sector 20 ha: 500 wells – 400 action wells – 10 remediation modules.

Sector 4 ha: 140 wells -120 of performance – 3 remediation modules.

Sector 1 ha: 25 wells – 20 action wells 1 remediation module.
