I do not remember hearing anything about what burned.  What was in that smoke?  What chemicals and minerals entered the groundwater system as part of the fire fighting operation. That water that was poured onto the fire had to go somewhere.  It flowed through a lot of burned liquid and special waste facility.

I think the public needs to be told.   No investigation by the Ministry of the Environment?

Nothing?    Why?

If I lived in Rosslyn, I sure would want to know.
