In June, the Department of National Defence (DND) sampled off-site residential water supplies near 22 Wing North Bay for PFAS and of 27 results received so far, two tested residences exceed the Health Canada screening values for drinking water.
BayToday has requested the actual numbers from DND.
Once confirmed, results will be made available.
"Acceptable levels for PFAS are guided by Health Canada drinking water screening values.
Screening values are established at a level designed to protect the health of Canadians, including children, based on a lifetime’s exposure to the substance.
The five remaining water sample results are expected shortly.
DND says it will immediately notify homeowners of any results that exceed the Health Canada screening values for drinking water, and will contact residents within one to two weeks of receiving validated results that are within the Health Canada screening values.
The last round of water testing, conducted in June, was to monitor for seasonal variability and to expand the sampling program in certain areas.
Residents that have not been contacted by DND regarding water sampling, are not in the affected area," says a DND release.
From the early 1970s to the mid-1990s, DND used extinguishing substances containing Perfluoroalkylated substances at former firefighting training areas at the North Bay Airport.
