OTIE delivers remediation investigations, treatability testing, design, and construction using innovative and traditional technologies to achieve restoration and closure. We are investigating emerging contaminants, including per- and polyfluoroalkyl substances (PFASs) at multiple sites. As an advocate for sustainable remediation, we have designed, pilot-tested, built, operated, and optimized enhanced in situ bioremediation (aerobic and anaerobic) systems to treat fuel residuals, chlorinated ethanes/ethenes, and chlorinated benzenes using compound specific isotope analysis (CSIA) to confirm biological activity.

With staff certified in the USACE three-phase construction control process, OTIE delivers sound, practical solutions with reduced life-cycle costs for long-term project value. Services include:

  • Remedial Investigation/Feasibility Studies and RFI/CMS
  • Risk Assessment (Human Health and Ecological)
  • Pilot/Treatability Testing
  • Remedial Design
  • Remedial/Removal Action
  • Long-Term O&M and Optimization
  • Habitat Restoration
