Environmental Remediation

Pioneer has successfully remediated over 1,000 sites of varying complexity in varying subsurface environments. Whether its soil remediation, soil gas/vapor mitigation, groundwater remediation, or commonly some combination of all three, Pioneer has designed and implemented remedial systems that work.

Pioneer’s remediation group consists of civil, mechanical, environmental and geotechnical engineers with extensive experience in the cleanup of sites impacted with petroleum and hazardous substances.

Each remediation project presents its own challenges and requires a thorough understanding of the contaminant and geologic conditions along with the specific type(s) of contaminant. Pioneer routinely handles sites contaminated with VOCs (volatile organic compounds), SVOCs (semivolatile organic compounds including PNAs), Metals, and PCBs (polychlorinated biphenyls). In many instances, co-mingling plumes and hot spot areas of differing contaminants means a hybrid approach may be the best solution.

The list below offers a sample of the different remediation systems and experience Pioneer can bring to your project.

  • Source Removal/Free Product Recovery
  • Conventional Soil Removal and Disposal (Dig and Haul)
  • In-Situ Chemical Oxidation
  • Vapor Mitigation
  • Metals Stabilization/Treatment
  • Biodegradation/Enhanced Natural Attenuation
  • Soil Vapor Extraction
  • Dual-Phase Extraction

From conventional remediation to complex in-situ remedial systems, Pioneer will evaluate the most feasible remedial approach from both an economic and technical perspective. We can design, install, operate and maintain virtually any remediation system to meet your specific needs.
