Help us collect fish samples to support arsenic research

What is this research about?

A human health risk assessment (HHRA) is currently being 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 will look at whether people are being exposed to chemicals at levels of concern, specifically arsenic, and will determine their level of risk. Canada North Environmental Services Ltd. (CanNorth) is conducting this assessment on behalf of the Government of the Northwest Territories (GNWT) and Indigenous and Northern Affairs Canada (INAC).

How can I participate?

An analysis of available data as part of the HHRA found there was limited information on fish from inland lakes around Yellowknife. A voluntary community fish sampling program will help to address this data gap.

To help with the study, we are looking for fish samples from the following lakes*:

  • Walsh
  • Banting
  • Prosperous
  • Prelude
  • River
  • Pontoon
  • Landing
  • Madeline
  • Ryan

*If there other additional lakes used for fishing, the program will also accept those samples from local residents. We are not currently looking for fish from Great Slave Lake.

Information on how to collect and return samples can be found here.

Samples will be collected until August 10, 2018.

Where can I find more information?

The Government of the Northwest Territories, Government of Canada and CanNorth held a public engagement session to talk about ongoing risk assessment work on legacy arsenic contamination on May 10, 2018.
