Thank you, Mr. Chair.
Thank you to the witnesses.
I'd like to start with Mr. BĂ©langer.
I know there's been some experience around the Mercier lagoons with PCBs, the contamination of groundwater and the plume that's created, which is a real challenge to drinking water.
Up in Kearl, we met with the representatives around the leak in the tailings pond. I recently spoke with Chief Tuccaro from the Mikisew Cree First Nation about the challenges there, which have naphthenic acid and heavy metals.
You mentioned in your testimony the monitoring and the tools that have been developed to monitor contamination. Could you tell us how those could be modified for areas where naphthenic acid is the concern, or where PCBs would be the concern somewhere else? Is this monitoring adaptable to the different conditions we're trying to monitor?
