As I said, similar to every EIA risk assessment I've reviewed in the oil sands region in the past 15 years, pathways were excluded based on the consultant's discretion of how the land was used.
The consultant looked at Health Canada guidance and worked through the guidance. It was really difficult for this region, knowing that it was Millennium EMS Solutions, which supports oil sands risk assessments. It does a lot of work in Alberta. The consultant would have had to almost actively ignore that indigenous people live in Fort Chipewyan to designate it commercial and exclude those pathways. I can't put it any other way.
In my professional opinion, I would expect the Alberta Society of Professional Biologists, if something like this came up, to look into how I conducted this study. I think APEGA would do the same.
