Project Background

Pipeline Release Incident

A pipeline failure resulted in approximately 20 cubic meters of condensate being released into the subsurface, creating significant environmental contamination that required immediate remedial action.

Contamination Scope

The release created substantial subsurface impacts:

• Initial Plume Area: 2,195 m²
• Original Impacted Soil Volume: 4,254 m³
• Contaminant Type: Condensate with benzene and associated hydrocarbons

Remediation Strategy

Site managers selected an integrated SVE/MPE (Soil Vapor Extraction/Multi-Phase Extraction) system to recover LNAPL and remediate subsurface contamination. The approach required optimization to maximize efficiency while minimizing operational costs.
