North Harbour Sediment Project

 

EcoSuperior is currently collecting public input into the proposed remedial options for the site. 

An online survey on the sediment options can be found here.

A summary of the sediment management options studied can be found here.

Frequently asked questions (FAQs) for the site can be found here.


The Thunder Bay North Harbour Project is a study involving collaboration between Environment Canada, The Ministry of Environment and Cascades Incorporated.  Approximately 300,000-350,000 m3 of mercury contaminated, enriched organic sediment (EOS) is presently sitting within the breakwall in the northernmost section of the Thunder Bay Harbour.   Studies have been ongoing since 2002 with the intention of remediating the site. Currently EcoSuperior is acting as the Project Manager for the Thunder Bay North Harbour Project with technical guidance coming from the stakeholders listed above.  

In late June, early July 2013 an additional round of field work was completed using a barge to further assess the chemical and geotechnical properties of the contaminated material. DST Consulting completed the field work component of the investigation.  The field work component consisted of 21 borehole locations and 10 testpits.  The Enriched Organic Sediment (EOS) was tested for a variety of geotechnical and chemical properties by DST, Maxxam Analytical and ALS Labs. The EOS material does not behave like typical sediment and some specialized analysis was required to insure that the data collected would be sufficient to proceed with the next stage in the process.  

Please check this website regularly for updates on this very important project. EcoSuperior intends to continue to work towards finding an effective remediation plan for the Thunder Bay North Harbour. 

For more detailed information please consult the previous site studies located here. Please provide any requests for further information or to provide input into the remedial option selection process, contact Jamie Saunders at 807-624-2658 or by email at ecosuperior%23org|Jamie.
