Award-Winning Oil Contamination Cleanup

  • Oil-contaminated site, before.
  • Successful site remediation in Azerbaijan

In less than two years, EnSafe cleaned up massive, decades-old oil contamination in the former Soviet Republic of Azerbaijan, demonstrating advanced western remediation technologies and project management approaches that the emerging democracy can apply to similar Cold War-legacy sites.

EnSafe was prime contractor in a design-build, full-scale remediation demonstration project on a 370-acre site contaminated with crude oil, highly mineralized produced water (brine), and solid waste.

For this successful technology-transfer effort, full-scale equipment has been left in place to continue remediating adjoining contamination on the Absheron Peninsula.

The project represents the first major cleanup effort of this legacy oil contamination using state-of-the-art bioremediation and soil-washing technologies and by an innovative approach of recycling contaminated soil into asphaltic concrete for use as pavement.

This innovative work won the 2007 Grand Iris Award in the American Council of Engineering Companies of Tennessee's Engineering Excellence competition.
