The City of North Bay and the Department of National Defence (DND) say they have reached an agreement that includes federal funding for remediation of per- and polyfluoroalkylated substances (PFAS) at Jack Garland Airport.

Immediate next steps will include issuing a request for proposals for engineering consulting services to aid the City in the environmental remediation process for the airport lands.

The scope of work will include environmental assessment, site-specific risk assessment, development of remediation objectives, treatability studies and remediation design.  Once a design is complete, the works will be tendered and remediation can begin.

“The city has been working proactively toward this agreement for the past two years. It is a major step that will advance PFAS cleanup efforts at the airport,” said Mayor Al McDonald. “The health and safety of our residents is our highest priority and we will continue to do all we can to move this remediation work ahead as quickly as possible.”

DND will provide up to $19.4 million over six years toward the airport PFAS cleanup, study, removal and remediation. The city will fund the balance of up to $600,000 over the same period. Additionally, the agreement allows the North Bay to submit a second proposal in the future for additional costs, if required.

“Our government has been working hard with our partners to leave a better environment to future generations. Though our work to solve the PFAS issue in North Bay is complex and ongoing, we remain committed to addressing this issue with the seriousness it deserves. By working together with our partners, including the City of North Bay, we are making real progress,” said the Hon. Harjit S. Sajjan, Minister of National Defence.

PFAS are manmade substances including firefighting foam. Past use of the airport lands for firefighter training between the early 1970s and mid-1990s has been identified as the main source of PFAS on the airport property.  Although firefighting foam containing PFAS was an accepted practice and was in accordance with regulations at that time, its use is very limited today.

Since 2017, testing and monitoring has been conducted for PFAS in Trout Lake, Lees Creek and residential wells in close proximity to the North Bay Jack Garland Airport lands. In order to expedite the remediation process, the municipality also completed its own environmental investigations into PFAS soil and groundwater contamination on the airport site.

The level of PFAS detected in the municipal water supply remains significantly lower than drinking water screening values set out by Health Canada and the interim guidance level provided by the MECP. A long-standing drinking water advisory for Lees Creek remains in place as well as a fish consumption advisory for fish from the creek issued by the MECP.
