A geophysical survey is underway around 22 Wing CFB North Bay, the Jack Garland Airport and various roadways.
They include sections of Airport Road, Carmichael Drive, Lees Road, Tower Drive, Trout Lake Road and Northmount Road.
Department of National Defence (DND) officials say the survey is being done as a part of their Per- and Polyfluoroalkylated Substances (PFAS) project to better understand the geology in the area.
The public is advised that traffic disturbances and sporadic noise (a small metal plate will be hit with a sledgehammer or truck-mounted hammer up to 30 times every hour) will occur during the work.
The project is running during the day and may include weekends until August 11th.
The residential wells are near the base where PFAS have been found, according to the Department of National Defence.
Firefighting foam containing high levels of PFAS was used from the 1970s to the 90s for training purposes before stricter regulations on the substances were enforced.
A report coming to North Bay City Council next week details a contribution agreement around remediation work, with DND providing $19.4 million over six years.
What is described in the report as “a very rough estimate” says the full project could cost upwards of $39 million.
The city will be able to file a second proposal to secure further funding once more detailed estimates are available.
Questions from the public regarding the geophysical survey can be directed to Department of National Defence’s Contaminated Sites Directorate at
