Remediation Demonstration Project 

Brownie Award Winner!

The City of Brantford's steam-enhanced extraction remediation demonstration project at the Greenwich Mohawk brownfield site has been awarded a Brownie Award from the Canadian Urban Institute! This award was in the category "Remediate" which recognizes achievements in sustainable remediation and technological innovation. The Project Team was comprised of the City of Brantford and Groundwater Technology, who attended the Brownie Award Ceremony in Toronto on October 29, 2014 to accept the award.

“This award is positive recognition of the ongoing work to remediate the Greenwich Mohawk brownfield site. Staff and Council have worked diligently to develop these resourceful partnerships and are working hard to advance the goal of Brantford as a centre for learning, and establish Brantford as the leader in brownfield remediation and redevelopment.” ~ Mayor Chris Friel

About the Project

The Technology:

Steam Enhanced Extraction

Who is Involved:

Groundwater Technology

Funding Partners:

How the Technology Works: 

Please see the Photo Album at the bottom of the page for a visual explanation.

There is a correlation between elevated temperatures in the groundwater and the mass removal of petroleum hydrocarbon product. Steam enhanced extraction technology injects steam into the soil that heats the groundwater and mobilizes the petroleum hydrocarbon contamination. Once mobilized, a vacuum based extraction system is used, which draws the mobilized contaminants towards it and into the extraction wells. Above ground, the extracted mixture is treated and petroleum hydrocarbon product is separated from the water. This technology is conceptually similar to what is used to extract oil from the tar sands in Alberta.

The Project Schedule:

  • Early September 2013: Installation of equipment
  • Mid-September 2013 - End of October 2013: Demonstration (approximately 8 weeks)<
  • End of October 2013: Final sampling and de-mobilization
  • November 2013 to Early 2014: Analysis and Reporting
  • Final Report 

Background:

In August 2012 Council approved retaining Groundwater Technology to demonstrate their remediation technology on a portion of 347 Greenwich Street. The City’s Agreement with Groundwater Technology was contingent on Groundwater Technology obtaining the necessary approval from the Ontario Ministry of Environment (MOE), as per the Environmental Protection Act, R.S.O. 1990.  Groundwater Technology retained Ontario-based environmental consultants Accuwerx to be its Canadian partner. On July 31, 2013 the MOE approved “one mobile in-situ thermal remediation process to treat contaminated soil and groundwater by the injection of steam into the contaminated soil and groundwater.”  

The demonstration project is now complete. The results of the demonstration project will be presented to City of Brantford Council on June 9, 2014 to share the results. A copy of the Final Results report will be available for download on June 6, 2014. If interested in receiving notice of the release of the report, please email Tara Tran.
