During the environmental assessment process for the Lower Churchill Project, an interim Human Health Risk Assessment was produced with a commitment to complete a final assessment following project sanction before changes to river conditions.

Components of this effort included:

• Consultation with relevant communities.
• Collection of human hair samples from the relevant communities for baseline determination of mercury concentrations.
• Dietary surveys – country and store-bought foods.
• Update of the Human Health Risk Assessment to include new baseline and updated exposure inputs.
• Development of a comprehensive monitoring program and health advisory protocol in consultation with Health Canada and the relevant communities.
