Transport Canada took years to notify residents of ‘forever chemicals’ in groundwater near airports
Transport Canada delayed notifying residents about toxic 'forever chemicals' in groundwater near airports for eight years. The chemicals, linked to serious health issues, were found in drinking water exceeding Health Canada's guidelines. Affected communities are now relying on bottled water as the federal government plans to impose further restrictions on these substances.
- ▪Transport Canada officials met with federal agencies about groundwater contamination from firefighting foams at least eight years before notifying affected communities.
- ▪The toxic compounds, known as PFAS, have been linked to cancer and other health issues.
- ▪Residents near Yarmouth International Airport and St. John's International Airport were only informed of the contamination recently, despite the known risks.
