Proven Technologies for Source Zone Remediation

AST installs a wide range of engineered mechanical remediation systems designed to remove or treat contaminants in soil and groundwater. Our capabilities include:

  • Soil Vapor Extraction (SVE) and Passive Vapor Extraction (PSVE)
  • Air Sparge (AS) Systems
  • Dual-Phase Extraction (DPE) and Multi-Phase Extraction (MPE)
  • High Vacuum Extraction (HVE) and Enhanced MPE (EME)
  • Groundwater Extraction and Treatment Systems (Pump & Treat)
  • Oil Water Separator (OWS) Systems

These systems are designed to efficiently reduce contaminant mass and vapor-phase risk in both saturated and unsaturated zones.

End-to-End Project Execution

AST provides support across every stage of the remediation process:

  • Site investigation and mass distribution assessment
  • Conceptual Site Model (CSM) development
  • Pilot testing and optimization
  • Full-scale system installation
  • System startup, operation, and maintenance (O&M)
  • Long-term monitoring and reporting

Our in-house technical staff, field crews, and equipment allow us to move from assessment to implementation without hand-offs or delays—ensuring tight project control and accountability.
