My program of research investigates the capacity of First Nations to manage drinking water resources. Through the federal drinking water system surveys I examine the capacity of First Nations to implement a multi-barrier approach. Following the federal risk evaluation guidelines, five categories – source water, design, operation, reporting, and operators – are combined to determine an overall risk ranking (i.e. low, medium, high) of First Nations drinking water systems. The risk rankings and other attributes are linked to a map of First Nations to examine spatial clusters and temporal change. I am currently participating in focus group discussions in First Nations to determine the perception of drinking water risk. How does the perception of risk compare with the federal governments assessment of risk? This research is funded through the Social Science and Humanities Research Council (SSHRC) and Nipissing University.
