A human health risk assessment (HHRA) was carried out for areas that are offsite but near to the former Giant Mine, primarily to the west and northwest of the mine site, and other areas that have been impacted by historical mining.
This study looked at whether people are being exposed to chemicals at levels of concern, specifically arsenic, and their level of risk.
Canada North Environmental Services Ltd. (CanNorth) conducted this assessment on behalf of the Government of the Northwest Territories (GNWT) and Indigenous and Northern Affairs Canada (INAC).
